Crystal's Coder Hub🧬 ICD-10 CM I69.111 — Memory Deficit Following Nontraumatic Intracerebral Hemorrhage
Billable Code Confirmed
ICD-10 CM I69.111 is a valid, fully billable 7-character ICD-10-CM code for FY2026. It is classified under Chapter 9 (Diseases of the Circulatory System), within the I60-I69 cerebrovascular diseases block, under category I69 (Sequelae of cerebrovascular disease), subcategory I69.1 (Sequelae of nontraumatic intracerebral hemorrhage), and sub-subcategory I69.11 (Cognitive deficits following nontraumatic intracerebral hemorrhage). This code is POA Exempt — no Present on Admission indicator is required on facility inpatient claims because sequela codes are by definition not present at the time of a new acute admission. The “7th character” structure reflects the full code hierarchy depth unique to the I69.1x series.¹²
Non-Billable Parent Codes
I69 (Sequelae of cerebrovascular disease) is the 3-character parent — not billable. I69.1 (Sequelae of nontraumatic intracerebral hemorrhage) is a 4-character subcategory — not billable. I69.11 (Cognitive deficits following nontraumatic intracerebral hemorrhage) is the 5-character sub-subcategory — also not billable as a header code requiring an additional character. All three parent levels require further specificity before a code can be submitted on a claim.¹²
Clinical Context — Sequela Code Rules and Timing
ICD-10 CM I69.111 is a sequela code — per ICD-10-CM coding guideline I.C.9.d, codes from category I69 are assigned to identify neurological deficits that persist after the initial acute phase of a cerebrovascular event (nontraumatic intracerebral hemorrhage in this case). Sequelae may be present from the onset of the hemorrhage or may arise at any time after the acute event — there is no time limit for assigning I69.x codes; they apply as long as the residual deficit persists and is documented.⁹⁴ Crucially, I69.111 is never assigned during the acute intracerebral hemorrhage encounter itself — during the acute admission, the hemorrhage code (I61.x) is the PDX and any concurrent neurological deficits are captured with that PDX; once the patient is in post-acute or ongoing care for residual deficits, I69.x codes apply. The provider must explicitly link the memory deficit to the prior intracerebral hemorrhage for I69.111 to be assigned — coders cannot independently infer this linkage.⁹⁸
Code Classification
ICD-10 CM I69.111 is a diagnosis code (ICD-10-CM) representing a specific cognitive sequela — memory impairment — resulting from prior nontraumatic intracerebral hemorrhage. It is not a procedure code, not a symptom code, and not an HCC-mapped condition under CMS-HCC V28. It is POA Exempt for facility inpatient claims and appropriate for use on post-acute UB-04 claims, IRF claims, outpatient CMS-1500 claims, and ongoing subsequent care encounters.¹²⁹⁸
🔍 Code Description
ICD-10 CMI69.111 captures a specific cognitive sequela of nontraumatic intracerebral hemorrhage (ICH) — memory deficit — as a persistent residual neurological effect of the hemorrhagic stroke. Intracerebral hemorrhage (ICH) refers to nontraumatic bleeding directly into the brain parenchyma, most commonly caused by hypertensive vasculopathy, cerebral amyloid angiopathy, or vascular malformations. Memory deficits following ICH result from direct neuronal destruction at the hemorrhage site, perilesional edema, and secondary injury to white matter tracts — the specific memory domains affected (short-term, long-term, working memory, prospective memory) depend on hemorrhage location, volume, and extent of secondary injury.⁹⁸ Basal ganglia, thalamic, and temporal lobe hemorrhages are particularly associated with memory impairment due to damage to structures integral to the Papez circuit and cortico-subcortical memory networks.²
The I69.11x cognitive deficit subcategory covers a spectrum of cognitive sequelae following intracerebral hemorrhage — memory deficit (I69.111) is one of six specific cognitive domains captured in this series, alongside attention/concentration (I69.110), visuospatial deficit and spatial neglect (I69.112), psychomotor deficit (I69.113), frontal lobe and executive function deficit (I69.114), cognitive social or emotional deficit (I69.115), and other cognitive symptoms (I69.118).² From an inpatient profee and facility coding perspective, I69.111 most commonly appears on post-acute rehabilitation admissions, neurological follow-up encounters, and IRF (inpatient rehabilitation facility) claims where cognitive deficits from prior ICH are being formally assessed and treated.⁹⁸ The code is POA Exempt, meaning facilities submitting inpatient claims do not need to assign a Present on Admission indicator for this code — an important operational note for HIM and coding teams managing UB-04 claim submission.⁴

I69.1x vs. I69.3x — Know Your Hemorrhage Type
The I69.1x series is exclusively for sequelae of nontraumatic intracerebral hemorrhage (I61.x). For sequelae of cerebral infarction (I63.x), the correct subcategory is I69.3x — and for sequelae of subarachnoid hemorrhage (I60.x), it is I69.0x. Memory deficit following ischemic stroke = I69.311; memory deficit following SAH = I69.011; memory deficit following ICH = I69.111. These are three distinct codes for the same clinical manifestation depending on the original stroke type. Provider documentation must identify the type of prior stroke before any I69.x code can be assigned.²⁹⁴
Multiple Cognitive Sequelae — Code All That Are Documented
Unlike some code families where a single “unspecified” code is acceptable, the I69.11x series is designed for granular specificity — each documented cognitive domain deficit should be separately coded. If a patient has both memory deficit (I69.111) AND frontal lobe/executive function deficit (I69.114) following ICH, assign both codes — they are not mutually exclusive. Multiple I69.11x codes may appear on the same claim when multiple cognitive domains are documented as affected.² Coders should review neuropsychological evaluation reports, OT/SLP assessments, and provider notes for any documented cognitive deficit domains.²
✅ Includes
- Memory impairment following nontraumatic intracerebral hemorrhage: Short-term, long-term, working memory, or prospective memory deficits persisting after ICH; all memory subtypes are captured under I69.111 without further specificity.¹²
- Amnesia following intracerebral hemorrhage: Anterograde or retrograde amnesia persisting as a sequela of nontraumatic ICH is included here.²
- Post-ICH cognitive memory deficit: Any clinically documented persistent reduction in memory capacity that the provider links to prior nontraumatic intracerebral hemorrhage.⁹⁸
- Short-term memory deficit post-hemorrhagic stroke: A common clinical presentation following thalamic or basal ganglia ICH; captured under I69.111 per the includes note hierarchy.²
- Verbal and nonverbal memory deficits: Both verbal memory (word list recall, story recall) and nonverbal memory (figure recall, spatial memory) deficits qualify when documented by the provider or neuropsychological evaluation linked to prior ICH.²
❌ Excludes
Excludes 1
The following conditions are mutually exclusive with I69.111 and should never appear on the same claim in contexts where the I69 category applies:¹³²¹⁴⁰
- Z86.73 — Personal history of cerebral infarction without residual deficit: This code applies when stroke caused NO lasting neurological deficit; if memory deficit IS present (as it is when I69.111 is coded), Z86.73 is incorrect — the residual deficit codes from I69.x take precedence. The two codes represent mutually exclusive clinical states.
- Z86.73 — Personal history of prolonged reversible ischemic neurologic deficit (PRIND) / reversible ischemic neurological deficit (RIND): Same principle — these history codes apply to fully resolved events with no residual; I69.111 applies when residual memory deficit persists.
- S06.- — Sequelae of traumatic intracranial injury: I69.111 is strictly for nontraumatic intracerebral hemorrhage sequelae. If the original hemorrhage was caused by trauma (e.g., motor vehicle accident), the sequela is coded from the S06.x traumatic injury series, not I69.x.
Most Common Excludes 1 Error: Mixing I69.111 with Z86.73
Assigning both I69.111 (memory deficit persisting as a sequela) and Z86.73 (history of stroke without residual deficit) on the same claim is an Excludes 1 violation — they represent mutually exclusive states. Z86.73 should only appear when the stroke caused NO lasting deficit. When memory or other cognitive deficits are present and ongoing, I69.x codes replace Z86.73. Auditors frequently flag this pairing as a clinical documentation inconsistency on post-acute and MA encounters.⁹⁸
Excludes 2
There are no Excludes 2 notations at the I69.111 code level in FY2026 ICD-10-CM.²
📋 Clinical Overview
Cognitive Sequelae Following ICH: Code Selection by Deficit Domain
The I69.11x series granularly captures each cognitive domain affected by prior intracerebral hemorrhage. Coders should map provider documentation — particularly neuropsychological evaluations, OT cognitive assessments, and neurology notes — to the appropriate domain-specific code. The table below illustrates the most clinically common comparisons and the correct code for each.²⁹⁸
| Cognitive Domain | Code | Descriptor | Common Clinical Documentation Trigger |
|---|---|---|---|
| Memory | I69.111 ◀ THIS CODE | Memory deficit following ICH | ”Memory impairment,” “amnestic syndrome,” “short-term memory loss,” “difficulty retaining new information” |
| Attention/Concentration | I69.110 | Attention and concentration deficit following ICH | ”Attention deficit,” “difficulty concentrating,” “distractibility post-stroke” |
| Visuospatial / Neglect | I69.112 | Visuospatial deficit and spatial neglect following ICH | ”Left neglect,” “spatial disorientation,” “visuospatial dysfunction” |
| Psychomotor | I69.113 | Psychomotor deficit following ICH | ”Processing speed deficit,” “psychomotor slowing,” “bradyphrenia” |
| Frontal / Executive | I69.114 | Frontal lobe and executive function deficit following ICH | ”Executive dysfunction,” “poor planning/organization,” “frontal syndrome” |
| Social/Emotional Cognition | I69.115 | Cognitive social or emotional deficit following ICH | ”Emotional dysregulation post-stroke,” “social cognition impairment,” “lack of empathy/insight” |
| Other | I69.118 | Other cognitive symptoms following ICH | Any documented cognitive deficit not fitting above categories |
CDI Trigger: Neuropsychological Evaluation Reports Are Gold
Neuropsychological evaluations performed in post-acute, IRF, or outpatient neuro settings often contain specific domain-by-domain cognitive deficit documentation — attention, memory, processing speed, executive function, visuospatial skills — that directly maps to I69.11x codes. CDI professionals and coders should request these reports during post-ICH admissions, as they frequently contain provider-signed deficit documentation that supports multiple I69.11x codes simultaneously and improves the clinical completeness of the record.²
Manifestations & Symptom Burden
- Hemiplegia following ICH (I69.151): The most HCC-relevant I69.1x code — maps to HCC 103 (Hemiplegia/Hemiparesis) under V28; frequently co-documented with cognitive deficits; code separately with the dominant/nondominant 5th character specified.⁹¹⁹³
- Aphasia following ICH (I69.120): Speech-language deficits may co-occur with memory impairment following ICH in dominant hemisphere or thalamic hemorrhages; code separately when documented.²
- Dysphagia following ICH (I69.191): Swallowing impairment is a frequent and high-burden complication of brainstem or large hemispheric ICH; code separately and note that dysphagia is a CC in some DRG contexts.²
- Depression following ICH (F32.9 or F06.31): Post-stroke/post-hemorrhage depression is clinically prevalent and frequently undercoded — code as F06.31 (mood disorder due to known physiological condition, depressive type) when the provider documents causative link, or F32.9 if documented as depression without explicit linkage.²
- Vascular dementia (F01.50): If cognitive deficits from ICH progress to full dementia criteria per provider documentation, a vascular dementia code (F01.5x series) may be appropriate in addition to or instead of the individual I69.11x deficit codes — provider documentation drives this distinction.²
Manifestation Coding Note
ICD-10 CM I69.111 is a sequela code — it is by definition a manifestation of a prior condition. It does not require an additional “code first” note; the prior hemorrhage is not re-coded alongside I69.111 in post-acute care (that would be incorrect — the ICH code I61.x is only assigned during the acute hemorrhage admission). The I69.x code series stands alone as the complete diagnosis for post-acute cerebrovascular sequelae encounters, per **ICD-10-CM guideline I.C.9.d.**²⁹⁴
💰 HCC Risk Adjustment
| Model | HCC Mapping | HCC Label | RAF Value |
|---|---|---|---|
| CMS-HCC V28 (PY2026) | ❌ Not Mapped | N/A — I69.11x cognitive series not risk-adjustable | 0.000 |
| CMS-HCC V24 | ❌ Not Mapped | N/A | 0.000 |
| RxHCC | ❌ Not Mapped | N/A | 0.000 |
ICD-10 CM I69.111 does not map to any HCC under CMS-HCC V28 — the entire I69.11x cognitive deficit subcategory is explicitly identified as non-HCC-mapped in published V28 crosswalk resources.⁹⁸ This is an important distinction within the I69.1x family: while I69.151-I69.154 (hemiplegia following ICH) do map to HCC 103, and certain other paralytic syndrome codes within I69.1x carry HCC weight, the cognitive sequelae codes (I69.110-I69.118) do not contribute to RAF scoring.⁹¹ CDI teams working on post-ICH Medicare Advantage encounters should prioritize ensuring hemiplegia (I69.15x), monoplegia (I69.13x, I69.14x), and any HCC-mapped paralytic deficits are fully documented and coded — while memory deficit and other cognitive I69.11x codes are clinically important for completeness, they carry zero RAF weight.⁹⁸ However, coexisting hypertension (I10), ischemic heart disease, atrial fibrillation, and other common ICH-associated comorbidities frequently map to HCC categories and should be captured at every applicable encounter.⁸
🏥 MS-DRG Assignment
| Scenario | MDC | DRG | DRG Title | I69.111 Role |
|---|---|---|---|---|
| I69.111 as PDX with MCC | MDC 01 | 091 | Other Disorders of Nervous System with MCC | PDX |
| I69.111 as PDX with CC | MDC 01 | 092 | Other Disorders of Nervous System with CC | PDX |
| I69.111 as PDX w/o CC/MCC | MDC 01 | 093 | Other Disorders of Nervous System without CC/MCC | PDX |
| I69.111 as secondary DX | Varies | Determined by PDX | N/A — not CC/MCC | Secondary comorbidity |
When I69.111 serves as the principal diagnosis (e.g., post-ICH memory deficit evaluation driving a neurology admission), it maps to MDC 01 and DRGs 091-093 based on secondary diagnosis CC/MCC burden.⁵ I69.111 itself is not a CC or MCC, so its presence as a secondary code does not independently influence DRG assignment. All I69.x codes are designated as POA Exempt — the Present on Admission indicator field is not required for these codes on facility inpatient claims.⁴ Coders working post-ICH inpatient admissions should focus CC/MCC capture on concurrent conditions such as aspiration pneumonia (J69.0, MCC), severe malnutrition (E43, MCC), sepsis (A41.9, MCC), pressure ulcers with full-thickness tissue loss (L89.x stage 3/4, MCC), and HAPI-related complications to support appropriate DRG tier assignment alongside I69.111.⁵

- 99233/99232 — Subsequent hospital care E/M: I69.111 appears as secondary diagnosis on inpatient subsequent care E/M codes when post-ICH cognitive deficits are managed during an inpatient stay.⁵
- 99483 — Assessment of and care planning for cognitive impairment: Highly relevant for post-ICH memory deficit workup; G-codes and CPT 99483 paired with I69.111 for comprehensive cognitive evaluation and care planning in the outpatient setting.²
NCCI Bundling Considerations
CPT 96132 (neuropsychological testing, first hour) and 96133 (each additional hour) are designed to be billed together for extended evaluations — NCCI edits permit both when the service spans more than one hour with distinct documentation.² When 97129 (cognitive therapeutic intervention) is billed alongside standard occupational therapy codes on the same day, NCCI edits may apply — documentation must clearly support separate therapeutic activities with distinct goals, and modifier -59 may be required.² I69.111 and associated I69.11x codes must appear in the supporting diagnosis fields of claims for neuropsychological testing and cognitive rehabilitation to establish medical necessity and satisfy payer LCD requirements for cognitive rehabilitation services.²
🔬 ICD-10-PCS Crosswalk
ICD-10-PCS codes apply to inpatient facility procedure reporting only.
- GZ3ZZZZ — Psychological testing (neurobehavioral/cognitive status): Represents inpatient neuropsychological or psychological assessment of cognitive function; directly pairs with I69.111 when formal cognitive testing is performed during an inpatient admission.²
- F09Z0ZZ — Assessment of cognitive functions: Represents inpatient evaluation of cognitive status by OT or SLP; supports I69.111 on the inpatient facility claim.²
- F06Z0ZZ — Speech treatment, motor speech, none: Represents SLP treatment targeting cognitive-communication deficits in post-ICH patients with memory and language sequelae.²
- GZ10ZZZ — Psychological individual counseling (behavioral): Relevant in inpatient psychiatric or rehabilitation settings where behavioral sequelae accompany cognitive deficits following ICH.²
💊 Coding Scenarios and Examples
Scenario 1: IRF Admission for Post-ICH Cognitive and Motor Rehabilitation
A 66-year-old female with a nontraumatic basal ganglia intracerebral hemorrhage (I61.0) three weeks ago is transferred to an inpatient rehabilitation facility. She presents with right-sided hemiparesis (right dominant), memory impairment documented by neuropsychology (“significant short-term memory deficit consistent with left thalamic involvement”), and mild aphasia per SLP evaluation.
Correct Coding:
- I69.151 — Hemiplegia and hemiparesis following nontraumatic ICH, right dominant side (PDX — the primary functional deficit driving IRF admission)
- I69.111 — Memory deficit following nontraumatic ICH (secondary — neuropsych documented)
- I69.120 — Aphasia following nontraumatic ICH (secondary — SLP documented)
Sequencing: I69.151 is PDX at IRF because it is the primary deficit driving rehabilitation need. I69.111 and I69.120 are secondary — both are clinically significant additional deficits documented by qualified providers and meeting UHDDS criteria. I61.0 (the original hemorrhage) is NOT recoded on the IRF claim — the I69.x series stands alone.
CDI Note: Note that I69.151 (hemiplegia following ICH) maps to HCC 103 — a high-value V28 HCC. Ensuring it is documented with dominant/nondominant specification is critical for risk adjustment capture. I69.111 and I69.120 carry no HCC weight but are clinically essential for the full picture and support cognitive rehabilitation medical necessity.⁹¹⁹²
Scenario 2: Outpatient Neurology Follow-Up — Memory Deficit as Primary Concern
A 74-year-old male with history of left putaminal intracerebral hemorrhage (8 months ago) presents to neurology for follow-up. His hemiparesis has largely resolved. The neurologist’s note states: “Residual post-ICH memory impairment persisting — patient and family report significant difficulty with day-to-day task recall. No new events. Refer to neuropsychology for formal testing.”
Correct Coding (Outpatient/Profee):
- I69.111 — Memory deficit following nontraumatic ICH (PDX/Primary DX — the presenting concern)
- I10 — Essential hypertension (secondary — documented active comorbidity)
Sequencing:I69.111 is the reason for this outpatient visit. I61.x (original hemorrhage) is NOT recoded. The sequela code (I69.111) stands alone to represent the current clinical picture.
CDI Note: This scenario illustrates that the I69.x codes stand alone — do not re-code the original I61.x hemorrhage alongside I69.111 on post-acute or outpatient claims. The I69.x series by definition replaces the acute hemorrhage code once the patient is in the sequela phase of care.²⁹⁴
Scenario 3: Incorrect Use of Z86.73 With Persistent Memory Deficit
A 71-year-old female presents for an annual wellness visit. Her chart shows a prior right thalamic ICH (2 years ago). She reports ongoing difficulty with short-term memory. The MA risk adjustment coder assigns Z86.73 (personal history of CVA without residual deficit) because the acute event was years ago.
Correct Coding:
- I69.111 — Memory deficit following nontraumatic ICH (the memory deficit persists — Z86.73 is wrong)
Incorrect Coding: Z86.73 — This code applies ONLY when there is NO residual neurological deficit. A patient with an ongoing, documented memory deficit from prior ICH must be coded with I69.111, not Z86.73. These two codes are mutually exclusive — they represent opposite clinical states.
CDI Note: This is a high-frequency risk adjustment coding error on annual wellness and MA encounter claims. The two codes are explicitly Excludes 1 to each other, and the clinical state — presence or absence of residual deficit — dictates which is correct. Using Z86.73 when a deficit persists underrepresents the patient’s clinical burden and, while I69.111 itself carries no HCC weight, the documentation integrity error may mask other HCC-relevant comorbidity capture opportunities.²⁹⁸
⚠️ Coding Pitfalls and Tips
-
Never Re-Code the Original Hemorrhage (I61.x) Alongside I69.111 in Post-Acute Care. Once the patient is past the acute ICH encounter, the hemorrhage code (I61.x) is no longer assigned — the I69.x sequela codes take over as the complete representation of the patient’s cerebrovascular status. Assigning both I61.x and I69.111 on the same post-acute or outpatient claim is a sequencing error. The acute I61.x code is used during the hospitalization when the hemorrhage occurred; I69.111 is used at any encounter thereafter when the memory deficit persists. This rule stems from ICD-10-CM Official Guideline I.C.9.d.¹²⁹⁴
-
Z86.73 and I69.111 Are Mutually Exclusive — Know Which Applies. Z86.73 (personal history of CVA/stroke without residual deficit) and I69.111 (memory deficit following ICH) represent opposite clinical states and are Excludes 1 to each other. If memory deficit persists, use I69.111. If the patient has fully recovered with no residual neurological deficit, use Z86.73. Never assign both simultaneously. This is one of the most common compliance errors on MA annual wellness and risk adjustment encounters involving post-stroke patients.⁹⁸
-
Use the Correct I69.x Subcategory — Match the Original Stroke Type. The I69.x family is organized by the type of original cerebrovascular event. Memory deficit following ICH = I69.111; memory deficit following SAH = I69.011; memory deficit following ischemic infarction = I69.311. Assigning the wrong subcategory (e.g., using I69.311 for a patient whose original event was ICH, not infarction) is a specificity error. Always confirm the type of prior stroke from the medical record before assigning an I69.x code.²⁹⁴
-
Code All Documented Cognitive Deficit Domains Separately — Don’t Default to I69.118. The I69.11x family contains seven domain-specific codes (I69.110-I69.118). When a neuropsychological evaluation or provider note documents multiple specific cognitive deficits (e.g., memory impairment AND executive function deficit AND attention deficit), each should be coded with its own I69.11x code — do not collapse all into I69.118 (other cognitive symptoms). This specificity reflects the actual clinical burden, improves data quality, and supports medical necessity for multidomain cognitive rehabilitation services.²
-
I69.111 Is POA Exempt — No POA Indicator Required on Facility Claims. All I69.x sequela codes are listed as POA Exempt in the CMS POA Indicator Table, meaning facility inpatient claims do not require a Present on Admission indicator for these codes. Coders and HIM teams do not need to assign POA = Y, N, U, or W to I69.111 on the UB-04. This is an operational claim submission point, not a clinical issue, but it prevents unnecessary claim edits.⁴
-
Provider Linkage Is Required — Do Not Independently Infer Sequela. ICD-10-CM requires that the provider explicitly link the memory deficit to the prior intracerebral hemorrhage before I69.111 can be assigned. A coder cannot independently determine that a patient’s memory impairment is attributable to a prior ICH based solely on chart review — the provider must document the relationship (e.g., “memory impairment secondary to prior intracerebral hemorrhage” or “post-ICH cognitive decline”). When the documentation includes memory impairment and a history of ICH but does not explicitly link them, a CDI query is required.⁹⁸²
