🧬 ICD-10 CM I69.120 — Aphasia Following Nontraumatic Intracerebral Hemorrhage
Billable Code Confirmed
ICD-10 CM I69.120 is a fully billable, valid 7-character ICD-10-CM diagnosis code effective for FY2026 (October 1, 2025 - September 30, 2026) with no changes to the code since its introduction in FY2016.1 It lives in Chapter 9 (Diseases of the Circulatory System) under category I69 (Sequelae of cerebrovascular disease) — specifically within the I69.12 subcategory (Speech and language deficits following nontraumatic intracerebral hemorrhage), which is itself a non-billable parent requiring extension to the fifth or sixth character for valid reporting.1 The code is designated as POA Exempt, meaning the present-on-admission indicator field on an inpatient claim must be populated with “1” (exempt) rather than Y/N/U/W, and CMS does not evaluate this code’s POA status for CC/MCC DRG payment determination purposes.1 I69.120 carries a chronic condition indicator, reflecting that post-stroke aphasia is a lasting condition affecting self-care, communication, and independent living for the duration of the patient’s life.1
Non-Billable Parent Codes
I69 (Sequelae of cerebrovascular disease) is a non-billable 3-character parent category — it serves as the chapter-level grouping for all cerebrovascular sequelae and cannot be submitted on any HIPAA-covered claim transaction without the required additional characters.1 I69.1 (Sequelae of nontraumatic intracerebral hemorrhage) is a non-billable 4-character subcategory identifying the hemorrhagic etiology class of the sequela, but it is insufficiently specific for billing and will be rejected by payers expecting a fully specified code.1 I69.12 (Speech and language deficits following nontraumatic intracerebral hemorrhage) is the non-billable 5-character parent immediately above I69.120, grouping all speech/language-specific sequelae of ICH — coders must extend to I69.120 (aphasia specifically) or one of its siblings to achieve a valid billable code, and using I69.12 alone constitutes a coding specificity error that will generate claim edits.1
Clinical Context
ICD-10 CM I69.120 is specifically assigned when the provider has documented aphasia — a language disorder affecting the ability to speak, comprehend, read, and/or write — as a direct residual deficit resulting from a prior nontraumatic (non-injury) intracerebral hemorrhage, meaning bleeding directly into the brain parenchyma from a non-traumatic cause such as hypertension, arteriovenous malformation, or amyloid angiopathy.2 The critical clinical and coding distinction separating I69.120 from its sibling I69.121 (dysphasia following nontraumatic ICH) is severity and completeness of language loss: aphasia indicates a more profound, global or near-global disruption of language function (expressive, receptive, or both), while dysphasia represents a partial or milder disruption of language ability — a distinction that must be anchored to the provider’s documented clinical impression, not the coder’s inference.2 This code should not be used for aphasia arising from ischemic stroke (use I69.320), subarachnoid hemorrhage (I69.020), or traumatic brain injury (S06.-), as each etiology has its own code series within I69.1 The sequela coding framework requires that the underlying original hemorrhagic event (I61.x) be coded separately when clinically relevant, particularly in inpatient rehabilitation and LTACH settings where the etiology informs the care plan.3
Code Classification
ICD-10 CM I69.120 is an ICD-10-CM diagnosis code representing a sequela — not an acute condition, not a symptom, and not a disease in its own active phase.1 It belongs to Chapter 9 (Diseases of the Circulatory System, I00-I99) rather than Chapter 6 (Diseases of the Nervous System) or Chapter 18 (Symptoms and Signs), which is a common source of lookup confusion because aphasia as a standalone presenting symptom is coded to R47.01 (Aphasia, not elsewhere classified) when no established neurological etiology has been documented.1
🔍 Code Description
ICD-10 CM I69.120 describes aphasia — a language disorder characterized by impaired ability to speak, understand spoken or written language, name objects, or formulate coherent verbal or written communication — occurring as a sequela (late effect) of a nontraumatic intracerebral hemorrhage (ICH).2 ICH refers to bleeding that occurs directly within the brain parenchyma from a nontraumatic cause; the most common etiology is chronic hypertension causing rupture of small penetrating arteries, followed by cerebral amyloid angiopathy in older adults, arteriovenous malformations, coagulopathies, and anticoagulant use.2 The hemorrhage causes direct neuronal injury and mass effect on the language-dominant hemisphere — typically the left hemisphere in right-handed individuals and in most left-handed individuals as well — with Broca’s area (inferior frontal gyrus, responsible for expressive language) and Wernicke’s area (posterior superior temporal gyrus, responsible for receptive language comprehension) being the most critical zones for aphasia generation.2 When I69.120 is coded, the language deficit is understood to be a chronic, persistent residual effect of the original bleed rather than an acute manifestation of ongoing hemorrhage — the acute phase of the hemorrhage itself, when present within the same episode of care, is coded from the I61.x category.3
Per ICD-10-CM Official Guidelines Section I.C.9.d, the category I69 is used to indicate conditions in I60-I67 as the cause of sequelae and includes conditions specified as such or as residuals that may occur at any time after the onset of the causal cerebrovascular condition — there is no time requirement before applying a sequela code, meaning I69.120 can be assigned in the same episode of care as the acute I61.x code if both the hemorrhage and the aphasia are documented simultaneously.3 R47.01 (Aphasia, not elsewhere classified) is the appropriate code when aphasia is documented as a presenting symptom without an established neurological etiology; once the physician documents aphasia as resulting from a prior ICH, R47.01 should be replaced by I69.120 for all subsequent claims.1 Coders working inpatient neurology, rehabilitation, and SNF claims will encounter I69.120 frequently and must be precise in distinguishing it from I69.121 (dysphasia — partial language disruption), I69.122 (dysarthria — motor speech disorder affecting articulation rather than language), and I69.123 (fluency disorder/stuttering following ICH), all of which are distinct sibling codes requiring separate and specific clinical documentation.1

Sequela Coding — No Time Limit and No POA Required
Unlike most inpatient diagnosis codes, I69.120 is exempt from POA reporting — you do not need to determine whether aphasia was present on admission because by definition a sequela exists from a prior event; enter “1” in the POA indicator field for this code on all inpatient UB-04 claims.1
Tip
The distinction between I69.120 (aphasia — complete or profound language loss) and I69.121 (dysphasia — partial language disruption) must come directly from physician documentation; do not infer aphasia severity from the SLP evaluation alone unless the attending physician has referenced or adopted those findings in their clinical notes. Query the attending when documentation uses the terms interchangeably or ambiguously, as code selection significantly impacts clinical accuracy and quality reporting metrics.2
✅ Includes
- Aphasia as sequela of nontraumatic intracerebral hemorrhage — The ICD-10-CM Alphabetic Index entry for “Aphasia — following — intracerebral hemorrhage” routes directly to I69.120; this is the only official inclusion term, and it encompasses all clinical types of aphasia (expressive/Broca’s, receptive/Wernicke’s, global, anomic) arising from the ICH sequela context.1
- Global aphasia following ICH — When the provider documents loss of nearly all language functions (inability to speak, understand, read, or write) as a post-ICH residual, I69.120 is the appropriate code because global aphasia is the most severe form of aphasia and falls within the aphasia descriptor; no separate code exists for global vs. expressive vs. receptive sub-types in ICD-10-CM within this series.2
- Expressive (Broca’s) aphasia following ICH — Post-ICH damage to Broca’s area resulting in halting, effortful speech with preserved comprehension is captured by I69.120 when documented as a residual of the hemorrhagic event.2
- Receptive (Wernicke’s) aphasia following ICH — Post-ICH damage to Wernicke’s area resulting in fluent but meaningless speech with severely impaired comprehension is coded to I69.120 when the provider documents this as an aphasia sequela of the hemorrhage.2
- Anomic aphasia following ICH — Word-finding and naming difficulties arising as a residual deficit of nontraumatic ICH fall within I69.120 when the provider characterizes the deficit as aphasia-type rather than a milder dysphasia.2
❌ Excludes
Excludes 1
Z86.73 — Personal history of cerebral infarction without residual deficit — An Excludes 1 note indicates mutual exclusivity: if a patient had a prior cerebral infarction with no remaining deficits, you code Z86.73, not I69.120 — the two cannot appear together on the same claim because I69.120 represents an active, present residual deficit while Z86.73 explicitly denotes an infarction that resolved without deficit.1 This exclusion is specific to the personal history of cerebral infarction (ischemic origin), and I69.120 captures hemorrhagic (not ischemic) origin sequelae, so this Excludes 1 functions as a guard against coding a hemorrhagic sequela alongside a history-of-ischemic-event-without-deficit code — they describe mutually exclusive clinical scenarios.1
S06.- — Sequelae of traumatic intracranial injury — Aphasia resulting from traumatic brain injury (TBI) must be coded from the S06.x category rather than I69.120, which is reserved exclusively for nontraumatic sequelae.1 Reporting I69.120 alongside a ∫ code violates the ∫ and misclassifies the etiology of the aphasia — this is a critical distinction for trauma cases, medicolegal documentation, and payer coverage determinations, as traumatic and nontraumatic etiologies trigger different authorization pathways and quality metrics.1
Danger
The most common Excludes 1 error with I69.120 is attempting to code post-ICH aphasia alongside a traumatic intracranial injury code (S06.-) — these two categories are mutually exclusive and describe completely different etiological mechanisms, and dual-coding them on the same claim will generate an NCCI edit denial and will be flagged in post-payment audits as an etiology misclassification error.1
Excludes 2
No official Excludes 2 notes are listed in the FY2026 ICD-10-CM Tabular for I69.120.1 Coders should note, however, that when a patient has both post-ICH aphasia (I69.120) and separately documented cognitive deficits following the same ICH (e.g., memory deficit — I69.111, or frontal lobe dysfunction — I69.114), both codes may and should be reported simultaneously on the same claim when both conditions are documented and addressed — each represents a distinct residual deficit from the hemorrhagic event and the absence of an Excludes 1 instruction between them permits multiple sequela codes from the I69.1x block to be reported together.1
📋 Clinical Overview
Aphasia vs. Related Speech/Language Sequela Codes Following ICH
The I69.12x subcategory captures five distinct speech and language deficits following nontraumatic ICH, and selecting the correct code requires precise alignment with provider documentation of the type and severity of communication impairment.2 The table below illustrates the key distinctions between I69.120 and its three most closely adjacent siblings, which are the codes most commonly confused in inpatient neurology and rehabilitation coding.2
| Feature | I69.120 | I69.121 | I69.122 | I69.123 |
|---|---|---|---|---|
| Condition captured | Aphasia — complete or profound disruption of language (expressive, receptive, or global); inability to speak, comprehend, read, or write at normal function. | Dysphasia — partial disruption of language ability; patient retains some language function but with significant impairment; milder than aphasia. | Dysarthria — motor speech disorder; articulation and phonation impaired due to muscle weakness or incoordination; language comprehension is intact; “slurred speech.” | Fluency disorder — stuttering or cluttering arising as a new onset residual of the ICH; characterized by involuntary interruptions, repetitions, or prolongations in speech flow. |
| Underlying mechanism | Cortical or subcortical damage to language network (Broca’s area, Wernicke’s area, arcuate fasciculus, or their interconnections) causing language processing failure at a linguistic level. | Same network as aphasia but less severe damage or more peripheral/subcortical involvement; partial preservation of language processing capacity. | Damage to motor speech pathways — corticobulbar tract, basal ganglia, cerebellum — impairing the muscular execution of speech without affecting linguistic comprehension or formulation. | Damage to supplementary motor area, basal ganglia, or cerebellar circuits regulating speech fluency and rhythm; represents a neurologically-based fluency disruption, not a developmental stutter. |
| SLP evaluation indicator | WAB-R (Western Aphasia Battery), BDAE, or similar aphasia-specific battery; aphasia quotient (AQ) is measurably reduced below normal limits. | WAB-R or similar; AQ is reduced but less severely than frank aphasia; patient may communicate with effort and cueing. | Frenchay Dysarthria Assessment, Motor Speech Evaluation; intelligibility ratings used; language testing reveals intact comprehension and formulation. | Stuttering severity instrument; speech fluency analysis; frequency of disfluencies, blocks, and repetitions measured as percentage of stuttered syllables. |
| CDI trigger | High — physician often documents “communication difficulties” or “word-finding problems” without specifying aphasia; query to establish aphasia vs. dysphasia vs. dysarthria based on SLP evaluation findings adopted by the attending. | Moderate — distinguish from aphasia via severity of language disruption; query when “aphasia” and “dysphasia” appear interchangeably in the same record. | Low confusion with I69.120 — dysarthria is mechanistically distinct; however, coders must not assume dysarthria equals aphasia because both involve speech difficulty. | Low frequency but high specificity — new-onset stuttering post-ICH is easily distinguished from developmental stuttering by the history of no prior fluency disorder. |
Important
Every inpatient encounter involving I69.120 is a CDI query opportunity — physicians and hospitalists frequently document “communication deficit,” “speech problems,” or “word-finding difficulties” in post-ICH patients without specifying the type of language impairment.3 An SLP evaluation in the chart almost always contains the specific characterization ([[aphasia]] vs. dysphasia vs. dysarthria), and when the attending physician adopts or references those findings, the more specific code can be reported. Concurrent physician query to establish the specific type of communication impairment improves coding accuracy, supports appropriate therapy utilization documentation, and ensures the correct code is assigned for quality metric purposes.
Manifestations & Symptom Burden
- Expressive language loss — The patient is unable to produce fluent, meaningful speech despite understanding what is being said; Broca’s aphasia variant results in telegraphic, labored output that is frustrating and exhausting for the patient, with significant impact on quality of life and independent communication.2
- Receptive language impairment — Damage to Wernicke’s area causes the patient to produce fluent but meaningless or paraphasic speech while being unable to comprehend spoken or written language; these patients may appear uncooperative or confused to clinical staff unfamiliar with aphasia presentations.2
- Reading and writing deficits (alexia/agraphia) — Post-ICH aphasia commonly involves co-occurring deficits in reading (alexia) and writing (agraphia), further compounding communication disability and reducing the patient’s ability to use compensatory strategies; these are included within the aphasia construct and do not require separate coding.2
- Functional communication dependency — Patients with I69.120-level aphasia typically require communication aids, caregiver interpretation, or AAC (augmentative and alternative communication) devices to participate in healthcare decisions, making informed consent and shared decision-making complex in the inpatient setting.2
- Psychosocial and behavioral sequelae — Post-stroke aphasia is strongly associated with depression, social isolation, and reduced participation in rehabilitation activities; when depression is separately diagnosed and documented, F32.9 or a more specific F32.x/F33.x code should be co-coded alongside I69.120 rather than assuming it is included in the aphasia code.3
Tip
When post-ICH aphasia is coded alongside other I69.1x sequela codes (e.g., hemiplegia, cognitive deficits, dysphagia), all documented residual deficits from the hemorrhagic event should be captured — there is no restriction limiting the number of I69.1x codes that can be reported on a single claim. Thorough sequela coding from the I69.1x category supports accurate functional status documentation, inpatient rehabilitation admission criteria justification (particularly for IRF-PAI requirements), and SNF MDS coding accuracy. Failure to capture all residual deficits is a CDI and compliance gap that can affect IRF case mix index and SNF RUG/PDPM category assignment.
💰 HCC Risk Adjustment
| Component | Value |
|---|---|
| HCC Model | CMS-HCC v28 (2026) |
| HCC Category | N/A — I69.120 not independently HCC-mapped |
| RAF Score Contribution | 0.000 (for I69.120 directly) |
| Chronic Condition Indicator | Chronic — meets 12-month duration and functional limitation criteria |
| Risk Adjustment Applicability | Indirect — signals need for annual I61.x capture |
| Annual Recapture Required | No for I69.120; Yes for underlying I61.x codes |
| Medicare Advantage Impact | Indirect — I69.120 presence should trigger I61.x HCC capture audit |
| PACE/ESRD Model Mapping | Not mapped |
ICD-10 CM I69.120 does not directly contribute to CMS-HCC risk scores under any active risk adjustment model, as sequela codes in the I69.x series are generally not assigned to HCC categories — the risk burden is captured by the underlying disease codes (I61.x) during the acute phase.4 However, the chronic condition designation of I69.120 and its clinical significance as evidence of ongoing neurological impairment make it a meaningful trigger for CDI review: any patient carrying I69.120 should be assessed annually to determine whether I61.x (nontraumatic intracerebral hemorrhage) is being documented and captured on claims, as that code does carry HCC weight and must be reported each calendar year when it continues to affect the patient’s health.4 For Medicare Advantage risk adjustment coders and CDI specialists, the presence of I69.120 on an outpatient or inpatient claim without a corresponding I61.x code elsewhere in the record is a gap that should be investigated through provider query — is the underlying hemorrhage still impacting the patient’s health status? If so, it must be documented and coded annually for accurate RAF capture.4
🏥 MS-DRG Assignment
| DRG Component | Value |
|---|---|
| MCE Principal Dx Restriction | None — I69.120 is valid as PDx when aphasia management/rehabilitation is the reason for admission |
| CC/MCC Status | Non-CC — does not contribute to DRG severity tier elevation |
| DRG Severity Contribution as Secondary | None |
| POA Indicator | Exempt — enter “1” on UB-04; field left blank or marked exempt |
| Typical DRG as PDx (Inpatient Rehab) | MDC 01 — Nervous System DRGs; IRF cases grouped by IRF-PAI CMG, not MS-DRG |
| Typical DRG as PDx (Acute Care) | DRG 056 — Degenerative Nervous System Disorders without MCC or DRG 052-053 grouping (context-dependent) |
| Common DRG when Secondary | Follows principal diagnosis MDC/DRG — no independent weight |
ICD-10 CM I69.120 is POA Exempt, meaning present-on-admission documentation is not required for this code and the “1” indicator must be entered in the POA field on inpatient UB-04 claims — failure to enter the correct POA indicator can generate a billing edit even for exempt codes.1 As a Non-CC secondary diagnosis, I69.120 provides no DRG severity uplift and does not shift a case between base, CC, and MCC DRG tiers — coders should not expect this code alone to improve DRG weight on an inpatient claim.1 In the inpatient rehabilitation (IRF) setting, MS-DRG logic does not apply; instead, the IRF-PAI Case Mix Group (CMG) drives reimbursement, and I69.120 as the rehabilitation impairment category (RIC) primary diagnosis directly contributes to CMG assignment when stroke is the impairment category — ensuring I69.120 is accurately listed as the rehabilitation diagnosis on the IRF-PAI is critical for correct CMG and tier assignment and therefore accurate IRF payment.3 CDI programs targeting post-ICH inpatient encounters should focus on capturing all secondary residual deficit codes (I69.1xx siblings) to ensure completeness, and should query for any CC/MCC-eligible comorbidities (e.g., hypertensive urgency, dysphagia, aspiration pneumonia, deep vein thrombosis) that co-exist with the sequela presentation and do carry DRG severity weight.
🔗 Related ICD-10-CM Codes
Aphasia by Cerebrovascular Etiology — Sequela Series
- I69.020 — Aphasia following nontraumatic subarachnoid hemorrhage — use when the hemorrhage originated in the subarachnoid space (not the parenchyma); etiology driven by ruptured aneurysm or AVM bleeding into CSF space.
- I69.120 — Aphasia following nontraumatic intracerebral hemorrhage — this code; parenchymal bleed etiology.
- I69.220 — Aphasia following other nontraumatic intracranial hemorrhage — use for bleeds classified to I62.x (e.g., subdural or extradural hemorrhage as sequela).
- I69.320 — Aphasia following cerebral infarction — use when the aphasia sequela is from ischemic stroke (I63.x), not hemorrhagic; this is the most common aphasia sequela code encountered in general practice given that ischemic stroke accounts for approximately 80% of all strokes.
- I69.920 — Aphasia following unspecified cerebrovascular disease — use only when the type of prior cerebrovascular disease cannot be determined from documentation; always query to specify etiology.
Acute Phase and Underlying Condition Codes
- I61.9 — Nontraumatic intracerebral hemorrhage, unspecified — the acute ICH code that may be reported simultaneously with I69.120 when both the acute hemorrhage and the aphasia sequela are documented in the same episode of care; also the code that carries HCC weight and should be reported annually when the hemorrhage continues to affect the patient’s health.
- I61.3 — Nontraumatic intracerebral hemorrhage in brain stem — a more specific acute ICH code when brainstem location is documented; brain stem ICH producing aphasia is relatively rare given language lateralization but occurs with thalamic extension.
- R47.01 — Aphasia, not elsewhere classified — the symptom-level code for aphasia when no definitive neurological etiology has been established; replace with I69.120 once the ICH etiology is documented.
- I61.0 — Nontraumatic intracerebral hemorrhage in hemisphere, subcortical — a common etiology for aphasia-producing hemorrhage when the bleed involves subcortical structures of the dominant hemisphere.
🛠️ Commonly Associated CPT Codes
- 92507 — Treatment of speech, language, voice, communication, and/or auditory processing disorder; individual. This is the most commonly billed CPT code paired with I69.120 for speech-language therapy services — SLP treatment of post-ICH aphasia is typically provided in individual sessions with I69.120 as the supporting medical necessity diagnosis; typically billed in 15-minute timed units per payer guidelines.5
- 92521 — Evaluation of speech fluency (e.g., stuttering, cluttering). While primarily associated with I69.123 (fluency disorder following ICH), this evaluation CPT may be billed alongside I69.120 when a comprehensive speech-language evaluation includes fluency testing as part of the aphasia workup; I69.120 supports medical necessity.5
- 92523 — Evaluation of speech sound production with evaluation and report of language comprehension and expression. The most comprehensive speech-language evaluation CPT code, capturing both language and speech sound assessment; paired with I69.120 when a full aphasia evaluation is being conducted including expressive/receptive language, articulation, and functional communication assessment.5
- 96105 — Assessment of aphasia (includes assessment of expressive and receptive speech and language function, language comprehension, speech production ability, reading, spelling, writing, e.g., by standardized instruments, with interpretation and report), per hour. This is specifically the aphasia assessment CPT code — a direct and natural pairing with I69.120 as its supporting diagnosis; billed per hour and requires a qualified SLP or physician.5
- 99223 — Initial hospital care, high complexity (inpatient). When a patient is admitted to acute inpatient with I69.120 as a primary concern alongside significant comorbidities, the admission H&P driving a high-complexity E/M is commonly reported; I69.120 supports the medical complexity documentation alongside the underlying ICH and other neurological codes.5
- 97129 — Therapeutic interventions that focus on cognitive function, initial 15 minutes; with subsequent 97130. These cognitive-behavioral intervention codes are frequently reported alongside I69.120 when the post-ICH patient presents with both aphasia and cognitive deficits — I69.120 pairs with relevant I69.11x cognitive deficit codes when multiple sequelae are present and being treated concurrently.5
NCCI Bundling Considerations
CPT 96105 (aphasia assessment) is not typically bundled with 92523 (speech-language evaluation) per NCCI edits when performed in the same session, but coders should verify current quarterly NCCI edit tables because evaluation code combinations are subject to medical necessity scrutiny by payers and bundling edits are regularly updated.5 Speech therapy treatment code 92507 is frequently subject to payer-specific caps, prior authorization requirements, and medical necessity criteria for post-stroke aphasia — particularly for Medicare beneficiaries under the therapy cap exceptions process, where I69.120 must be present on each claim to document the chronic nature of the communication deficit justifying continued skilled therapy beyond standard thresholds.5 When multiple speech-language evaluation codes are billed on the same date of service (e.g., 92523 with 96105), payers will scrutinize the claim for duplicate billing, and coders must confirm the scope of each service was distinct, separately documented, and not duplicative of the other before reporting both on the same claim.
🔬 ICD-10-PCS Crosswalk
ICD-10 CM [[I69.120]] as a diagnosis code maps to several ICD-10-PCS procedure codes that would appear on an inpatient record when the sequela is being actively treated or evaluated:
- F00Z6ZZ — Speech Treatment, Nonspoken Language, None — from the Physical Rehabilitation and Diagnostic Audiology section (F), Body System 00 (Rehabilitation), Root Type Z (Speech Treatment), Qualifier 6 (Nonspoken Language); used when AAC (augmentative and alternative communication) interventions are provided to the patient with global aphasia who cannot produce or understand spoken language, a common inpatient rehabilitation procedure for severe I69.120-level presentations.1
- F00ZHZZ — Speech Treatment, Aphasia, None — the most directly applicable PCS code for aphasia-specific speech therapy in the inpatient rehabilitation context; qualifier H specifically designates aphasia treatment, making this the PCS code most precisely aligned with I69.120 as the driving diagnosis on an IRF or acute inpatient rehab claim.1
- F00Z5ZZ — Speech Treatment, Voice Analysis, None — used when voice and speech production analysis is performed as part of the inpatient comprehensive speech-language rehabilitation program alongside aphasia treatment; may be coded in addition to F00ZHZZ when both services are documented.1
- GZ3ZZZZ — Mental Health Screening, No Qualifier — may appear on records with I69.120 when psychiatric screening is conducted as part of the inpatient evaluation for post-stroke depression or adjustment disorder complicating the aphasia rehabilitation course; coded from the Mental Health section when performed by a qualified mental health professional.1
💊 Coding Scenarios and Examples
Scenario 1 — Acute Inpatient Admission with Simultaneous ICH and Aphasia Documentation
A 67-year-old male with a history of poorly controlled hypertension is brought to the ED by his wife who noticed he suddenly could not speak and had right-sided arm weakness. CT of the head reveals a left basal ganglia intracerebral hemorrhage measuring 2.3 cm in diameter. MRI confirms parenchymal hemorrhage without midline shift. The attending neurologist documents: “Patient presents with acute nontraumatic intracerebral hemorrhage, left basal ganglia, with resultant global aphasia and right hemiplegia.” Neurosurgery is consulted and determines no surgical intervention is needed. The patient is admitted for medical management and SLP/PT/OT consults are placed. The SLP evaluates the patient and documents global aphasia with WAB-R aphasia quotient of 12/100. The attending adopts these findings.
Correct Coding:
- PDx: I61.0 — Nontraumatic intracerebral hemorrhage in hemisphere, subcortical — the acute hemorrhage is what prompted the admission; it is the condition chiefly responsible for the admission and is sequenced first.
- SDx: I69.120 — Aphasia following nontraumatic intracerebral hemorrhage — per ICD-10-CM guidelines, when the acute event and sequela are both present and documented in the same episode of care, both can be reported; the sequela code is appropriate here given the neurologist explicitly documented the aphasia as resulting from the hemorrhage.
- SDx: I69.151 — Hemiplegia and hemiparesis following nontraumatic intracerebral hemorrhage affecting right dominant side — the right hemiplegia documented should be captured as an additional sequela code; confirms bilateral coding of I69.1x sequelae is permitted.
- SDx: I10 — Essential (primary) hypertension — documented comorbidity contributing to the etiology of the hemorrhage.
Sequencing: I61.0 is the PDx per UHDDS guidelines as it is the reason driving the admission. I69.120 and I69.151 are additional diagnoses per Section I.C.9.d of the ICD-10-CM guidelines, which explicitly permits sequela coding in the same episode as the acute event when both are documented. POA for I69.120 must be entered as “1” (exempt). CDI Note: Confirm the attending physician has documented the aphasia as directly resulting from the ICH in their own words — SLP documentation alone does not establish etiology for coding purposes unless the attending adopts those findings.
Scenario 2 — Inpatient Rehabilitation Admission for Post-ICH Aphasia
A 71-year-old female is transferred from acute care to an inpatient rehabilitation facility (IRF) 8 days after a left hemisphere nontraumatic intracerebral hemorrhage. She presents with significant expressive aphasia (Broca’s type, WAB-R AQ = 38), mild right arm paresis, and is able to ambulate with supervision. She is admitted to IRF for intensive speech therapy, OT, and PT. The physiatrist’s admission note documents: “Patient admitted for intensive rehabilitation following nontraumatic intracerebral hemorrhage with residual expressive aphasia as primary rehabilitation impairment, right arm weakness as secondary impairment.” The IRF-PAI lists stroke as the RIC.
Correct Coding (IRF Facility):
- PDx (IRF-PAI Primary Impairment): I69.120 — Aphasia following nontraumatic intracerebral hemorrhage — the primary rehabilitation diagnosis and reason for the IRF admission; drives CMG assignment on the IRF-PAI.
- SDx: I69.191 — Monoplegia of upper limb following nontraumatic ICH affecting right dominant side (or appropriate I69.13x code per specificity) — the right arm paresis is an additional residual deficit from the same hemorrhage.
- SDx: I61.9 — Nontraumatic intracerebral hemorrhage, unspecified — the underlying hemorrhage should be coded as an additional diagnosis to provide etiologic context and support HCC capture in the patient’s longitudinal record.
Sequencing: I69.120 is the appropriate PDx for the IRF admission as it represents the primary rehabilitation impairment driving the admission. Multiple I69.1x codes can and should be reported when multiple residual deficits are documented. CDI Note: The IRF-PAI impairment category code for “Stroke” requires specific rehabilitation impairment documentation — ensure the physiatrist’s admission note clearly links each residual deficit to the hemorrhagic event rather than using vague language like “neurological deficits.”
Scenario 3 — Outpatient Neurology Follow-Up Post-Discharge
A 58-year-old male presents to outpatient neurology for a 90-day follow-up after discharge from acute inpatient care for a right thalamic intracerebral hemorrhage. The neurologist documents: “Patient continues to demonstrate aphasia as a sequela of his prior nontraumatic intracerebral hemorrhage. Aphasia has mildly improved per SLP report; patient continues weekly outpatient SLP therapy. No new neurological events. Hypertension well-controlled on current regimen.” The visit is a moderate-complexity established patient E/M.
Correct Coding:
- CPT: 99214 — Office or other outpatient visit, established patient, moderate medical decision-making.
- PDx: I69.120 — Aphasia following nontraumatic intracerebral hemorrhage — the primary reason for the visit is management of the post-ICH aphasia sequela; this is appropriately the first-listed diagnosis on an outpatient claim.
- SDx: I61.9 — Nontraumatic intracerebral hemorrhage, unspecified — reporting the underlying hemorrhage as an additional diagnosis supports HCC annual recapture for MA payers and provides etiologic completeness.
- SDx: I10 — Essential (primary) hypertension — documented, treated comorbidity; always code active, managed conditions per outpatient coding guidelines.
Sequencing: I69.120 is first-listed as it is the condition chiefly responsible for the outpatient encounter. I61.9 and I10 are additional diagnoses. Note that in outpatient coding, only confirmed conditions are reported — do not add new diagnoses from the SLP report unless the physician has confirmed them. CDI Note: Annual reporting of I61.9 on MA patient claims alongside I69.120 is a best practice for HCC gap closure; the hemorrhage history directly impacting the patient’s current neurological status should be captured every year in the medical record and reflected in coding.
⚠️ Coding Pitfalls and Tips
-
Pitfall 1 — Confusing aphasia (I69.120) with dysphasia (I69.121): These two sibling codes represent different degrees of language impairment and must not be used interchangeably even though some providers and SLPs use the terms loosely in documentation.2 Aphasia represents a more profound language disruption and dysphasia a milder one — when provider documentation is ambiguous or uses both terms, a concurrent physician query is required to establish which code is appropriate. Defaulting to I69.120 when dysphasia might be more accurate — or vice versa — is a coding specificity error that affects quality metrics, rehabilitation program classification, and the accuracy of the clinical record.
-
Pitfall 2 — Failing to enter POA “1” (exempt) on inpatient claims: I69.120 is POA Exempt, but exempt codes still require an indicator — the correct entry is “1” (unreported/not used — exempt from POA reporting), not a blank field and not “Y” or “N.”1 Many coders and billers incorrectly leave the POA field blank for exempt codes or enter “Y” by default, which can cause claim processing edits depending on payer adjudication logic. Train billing staff to recognize the exemption list and enter “1” correctly on all UB-04 claims containing POA-exempt codes.
-
Pitfall 3 — Omitting the underlying ICH code (I61.x) when clinically relevant: The sequela code I69.120 tells the payer what residual deficit exists but does not explicitly communicate the underlying cause without the I61.x etiology code also being present in the record.3 In IRF, LTACH, SNF, and MA risk adjustment contexts, omitting the I61.x code leaves HCC capture on the table and reduces clinical documentation completeness. Always evaluate whether the underlying hemorrhage should be coded as an additional diagnosis — it almost always should be, especially in the first year post-event and in any encounter where it directly influences the patient’s care plan.
-
Pitfall 4 — Using I69.120 for aphasia from ischemic stroke: I69.120 is exclusively for aphasia following nontraumatic intracerebral hemorrhage (parenchymal bleed).1 Aphasia from cerebral infarction (ischemic stroke) must be coded to [[I69.320]], not I69.120. This is one of the highest-frequency specificity errors in cerebrovascular sequela coding because aphasia is far more common post-ischemic stroke than post-ICH, and coders who do not verify the type of prior cerebrovascular event will default to the wrong code. Always confirm the hemorrhagic vs. ischemic nature of the prior event from the acute care discharge summary, imaging reports, or the treating physician’s documentation before assigning any I69.1x code.
-
Pitfall 5 — Not coding all documented residual ICH deficits concurrently: ICD-10-CM permits — and best practice requires — reporting all documented residual deficits from the same ICH event using multiple I69.1x codes on a single claim.3 Coders who report only I69.120 and miss co-documented deficits like cognitive impairment (I69.11x), hemiplegia (I69.15x), dysphagia (I69.191), or monoplegia (I69.13x) are producing an incomplete claim that underrepresents the patient’s functional burden, may undermine IRF-PAI CMG tier assignment, and creates CDI gaps in the longitudinal record. Review the full physician documentation, SLP evaluation, PT/OT assessments, and discharge summary for all documented residual deficits before finalizing the code list.
-
Pitfall 6 — Using R47.01 when I69.120 should be reported: R47.01 (Aphasia, not elsewhere classified) is the appropriate code when aphasia is a presenting symptom without an established etiology.1 Once the provider has documented that the patient’s aphasia is a residual of a prior nontraumatic ICH, R47.01 must be replaced by I69.120 on all subsequent claims — continuing to code R47.01 after the etiology is established is a coding specificity failure that ICD-10-CM guidelines Section I.C.18 prohibit. This transition from symptom code to sequela code commonly occurs between the acute inpatient admission and the first outpatient follow-up visit, and coders handling both settings should ensure the code upgrade occurs correctly at the appropriate point in the episode of care.
