🧬 ICD-10 CM I69.198 — Other Sequelae of Nontraumatic Intracerebral Hemorrhage
Billable Code Confirmed
ICD-10 CM I69.198 is a fully billable, 7-character ICD-10-CM code valid for FY2026, serving as the “other specified” residual sequela code within the I69.19 subcategory. The code structure identifies: I69 (sequelae of cerebrovascular disease) → .1 (nontraumatic intracerebral hemorrhage) → .19 (other sequelae) → .198 (other specified sequelae not captured by I69.190-I69.193). This code is POA-exempt as a sequela condition and carries official ICD-10-CM Includes notes specifying alteration of sensations and disturbance of vision as its primary intended clinical applications.
Non-Billable Parent Codes
I69 (Sequelae of cerebrovascular disease) is a non-billable category-level code requiring additional characters to specify both the type of cerebrovascular event and the nature of the residual deficit. I69.1 (Sequelae of nontraumatic intracerebral hemorrhage) is non-billable — it identifies the event type but entirely lacks deficit specificity, making it unacceptable as a standalone reported code. I69.19 (Other sequelae of nontraumatic intracerebral hemorrhage) is equally non-billable as a subcategory header — all three parent codes require extension to the 6th or 7th character for valid claim submission.
Clinical Context
ICD-10 CM I69.198 is critically distinct from the other I69.19x codes because it is a residual “catch-all” — it may ONLY be used when the documented residual deficit following nontraumatic ICH is NOT captured by any of the more specific codes in the I69.19x family (I69.190 apraxia, I69.191 dysphagia, I69.192 facial weakness, I69.193 ataxia). The ICD-10-CM Includes notes identify alteration of sensations and disturbance of vision as the primary clinical scenarios for I69.198, covering residual deficits such as hemisensory loss, paresthesia, hemianopia, diplopia, and other visual field defects that follow a prior nontraumatic ICH and lack more specific sequela code assignments in the I69.19x range.
Code Classification
ICD-10 CM I69.198 is an ICD-10-CM diagnosis code — it is NOT a procedure code and carries no CPT or ICD-10-PCS equivalent. It classifies a sequela (late effect) of disease, meaning the acute hemorrhagic phase has resolved and this code represents the residual neurological deficit. It is never appropriate to code I69.198 simultaneously with an active acute intracerebral hemorrhage code (I61.-) for the same hemorrhagic event. Equally important: I69.198 must never be used as a substitute for a more specific I69.19x code when one exists — its catch-all nature makes it an audit target when specific codes are available and not used.
🔍 Code Description
ICD-10 CM I69.198 serves as the “other specified” catch-all sequela code for residual neurological deficits following nontraumatic intracerebral hemorrhage that are not captured by any of the more precise codes in the I69.19x subcategory. The official ICD-10-CM Includes notes provide two explicit clinical anchors: (1) alteration of sensations following nontraumatic intracerebral hemorrhage — covering hemisensory loss, paresthesia, hypoesthesia, dysesthesia, or other somatosensory disturbances resulting from hemorrhagic disruption of thalamic, parietal somatosensory cortex, or sensory pathway structures; and (2) disturbance of vision following nontraumatic intracerebral hemorrhage — covering hemianopia, quadrantanopia, visual field defects, diplopia, cortical visual impairment, or other visual deficits resulting from hemorrhage in the occipital lobe, optic radiations, or visual processing pathways. These are among the most clinically significant and functionally impactful post-ICH sequelae after motor deficits, yet they lack dedicated specific codes in the I69.19x family, making I69.198 their correct and intended home.
Per ICD-10-CM Guideline I.C.9.d, there is no time limitation on assigning sequela codes from category I69 — I69.198 may be used from the time the alteration of sensation or visual disturbance is first identified post-ICH or documented years later as a persistent residual. The hemorrhagic lesion location directly determines which of these “other” sequelae manifest: thalamic and parietal ICH most commonly produce sensory alteration (the thalamus being the primary sensory relay nucleus), while occipital and posterior temporal ICH most commonly produce visual field defects through disruption of the primary visual cortex or optic radiations. Clinicians and CDI specialists should note that “disturbance of vision following nontraumatic ICH” coded at I69.198 is distinct from more anteriorly-located visual problems — a patient with diplopia from brainstem ICH affecting cranial nerve nuclei or from occipital ICH affecting cortical vision processing would both map to I69.198, but the clinical documentation needs to specify the visual disturbance type to fully support medical necessity for neuro-ophthalmology or low vision rehabilitation services.

The Critical Catch-All Rule — When I69.198 Is and Is NOT Appropriate
ICD-10 CM I69.198 is only correct when the documented post-ICH residual deficit is NOT represented by I69.190 (apraxia), I69.191 (dysphagia), I69.192 (facial weakness), or I69.193 (ataxia). The most appropriate clinical targets for I69.198 are deficits explicitly listed in its Includes notes — alteration of sensations (hemisensory loss, paresthesia, dysesthesia) and disturbance of vision (hemianopia, visual field defect, diplopia, cortical visual impairment). Using I69.198 for facial weakness, dysphagia, apraxia, or ataxia when those specific codes exist is a coding error — auditors and payers expect maximum specificity and will flag the catch-all when a more precise code is available and documented.
Tip
When a patient with prior nontraumatic ICH is documented to have sensory changes or visual disturbances, query the physician to confirm: (1) the explicit causal link to the prior nontraumatic ICH, (2) the specific type of sensory or visual deficit (hemisensory loss, hemianopia, diplopia, paresthesia) to support medical necessity documentation for neuro-ophthalmology or sensory rehabilitation, and (3) whether concurrent motor, speech, or swallowing deficits are also present that warrant more specific I69.19x codes alongside I69.198.
✅ Includes
- Alteration of sensations following nontraumatic intracerebral hemorrhage — official ICD-10-CM Includes note; covers hemisensory loss, paresthesia (abnormal tingling or burning sensation), hypoesthesia (reduced sensation), dysesthesia (painful abnormal sensation), and somatosensory disturbances resulting from hemorrhagic disruption of the thalamus, thalamocortical projections, parietal somatosensory cortex (areas S1/S2), or the posterior limb of the internal capsule.
- Disturbance of vision following nontraumatic intracerebral hemorrhage — official ICD-10-CM Includes note; covers homonymous hemianopia (loss of half the visual field in both eyes contralateral to the lesion), quadrantanopia, visual field defects, diplopia (double vision from cranial nerve or brainstem involvement), cortical visual impairment, and visual processing disorders resulting from hemorrhage in the occipital lobe, optic radiations, or posterior visual pathway.
- Post-ICH hemisensory syndrome — complete or partial loss of sensory modalities (pain, temperature, proprioception, vibration) on the contralateral side of the body following thalamic or parietal ICH; functionally significant for balance, fall risk, and ADL performance, and supports OT and PT rehabilitation referrals.
- Post-ICH visual neglect (hemispatial neglect with visual component) — when specifically a visual attention/awareness deficit following ICH is documented without qualifying as apraxia or a motor planning disorder; the visual component of neglect may be captured here when other cognitive neglect codes do not fully represent the documented deficit.
❌ Excludes
Excludes 1
ICD-10 CM Z86.73 — Personal history of cerebral infarction without residual deficit (PRIND/RIND): This Excludes 1 note at the I69 category level prohibits coding Z86.73 simultaneously with I69.198 because Z86.73 is only appropriate when NO residual neurological deficits are present from a prior cerebrovascular event. Any active residual sequela — including the altered sensation or visual disturbance captured by I69.198 — means the patient does not qualify for Z86.73, and billing both together is a non-compliant, contradictory code pairing that will flag on audit. S06.- — Sequelae of traumatic intracranial injury: This Excludes 1 note prohibits I69.198 when the sensory or visual sequela resulted from a traumatic brain injury — traumatic etiology requires codes from the S06 injury chapter with the appropriate sequela 7th character (S), and these two code families are never reported together for the same event.
Danger
The most common Excludes 1 error with I69.198 is assigning Z86.73 alongside it when a coder finds the ICH history in the problem list and reflexively adds a “history of” code without recognizing that the documented active sensory or visual residual makes Z86.73 categorically incorrect. A secondary common error is applying I69.198 when a more specific I69.19x code exists — this is not an Excludes violation but is a specificity failure that constitutes incorrect coding under the official guidelines’ instruction to code to the highest level of specificity.
Excludes 2
ICD-10 CM I69.398 — Other sequelae of cerebral infarction: This Excludes 2 scenario means that if a patient has a history of BOTH a prior nontraumatic ICH AND a separate prior cerebral infarction, each producing its own distinct “other” residual deficit (e.g., sensory alteration from the ICH and a separate visual disturbance from the infarction), both I69.198 and I69.398 could theoretically be reported simultaneously when documentation supports two discrete causative events with separately attributable deficits. In practice this requires unambiguous physician documentation specifying which sensory or visual deficit traces to the ICH versus the infarction — a high-complexity CDI query scenario most commonly encountered in elderly patients with mixed cerebrovascular disease histories.
📋 Clinical Overview
The “Other Specified” Role: Sensory and Visual Sequelae of ICH
ICD-10 CM I69.198 occupies a unique structural position in the I69.19x family — it is the only code in this subcategory explicitly anchored to two distinct clinical deficit categories (sensory alteration and visual disturbance) via official Includes notes, rather than serving as a true unspecified catch-all. This makes I69.198 more clinically targeted than its “other” designation implies: coders and CDI specialists should think of it primarily as the sensory sequela code and the visual sequela code for post-ICH residuals, while recognizing it also accommodates any truly atypical post-ICH deficit not covered by I69.190-I69.193. The neuroanatomical location of the ICH is the primary driver of whether I69.198 applies — thalamic and posterior parietal hemorrhages most commonly produce the sensory alterations, while occipital and posterior temporal hemorrhages most commonly produce the visual disturbances captured by this code.
| Feature | I69.198 | I69.190 | I69.193 |
|---|---|---|---|
| Primary Deficit Type | Sensory alteration OR visual disturbance (per Includes notes); other unspecified residuals | Apraxia — motor programming disorder | Ataxia — cerebellar/vestibular coordination disorder |
| Typical ICH Location | Thalamic, parietal (sensory); occipital, posterior temporal (visual) | Left parietal, frontal, supplementary motor area | Cerebellar, brainstem, thalamic |
| Rehab Specialty Driver | Neuro-ophthalmology, low vision rehab, sensory OT, neuropsychology | SLP (apraxia of speech), OT (limb apraxia) | PT (balance, gait), vestibular therapy |
| Use When | Documented sensory or visual residual with no more specific I69.19x code available | Documented apraxia (any subtype) linked to ICH | Documented ataxia linked to ICH |
| HCC Impact (V28) | None | None | None |
| Do NOT Use When | Apraxia, dysphagia, facial weakness, or ataxia are the primary documented deficit | Sensory or visual deficit is the primary documented deficit | Sensory or visual deficit is the primary documented deficit |
Important
CDI trigger: When a provider documents “sensory loss,” “numbness,” “tingling,” “visual field cut,” “hemianopia,” “double vision,” “visual disturbance,” or “cortical vision loss” in a patient with prior nontraumatic ICH, query to confirm: (1) explicit causal linkage to the prior ICH, (2) the specific sensory modality or visual deficit type (to support medical necessity for specialist referrals), and (3) whether motor deficits are also present that would warrant additional I69.1x codes — particularly hemiplegia/hemiparesis codes carrying HCC 103 under V28.
Manifestations & Symptom Burden
- Hemisensory loss (captured within I69.198): Complete or partial loss of pain, temperature, touch, or proprioception on the contralateral side following thalamic or parietal ICH; increases fall risk, impairs ADL performance, and may cause central post-stroke pain syndrome — each of these functional consequences supports medical necessity for inpatient rehabilitation services.
- Homonymous hemianopia (captured within I69.198): Loss of the same half of the visual field in both eyes contralateral to the hemorrhagic lesion; most commonly follows occipital ICH; significantly impacts driving safety, reading, navigation, and occupational function — supports neuro-ophthalmology referral and low vision rehabilitation services.
- Central post-stroke pain (G89.29 when documented as distinct chronic pain condition): Deafferentation pain resulting from thalamic ICH disrupting pain processing pathways; not captured within I69.198 itself but frequently coexists — assign separately when documented as a distinct chronic pain diagnosis by the treating provider.
- Diplopia (captured within I69.198 when sequela of ICH): Double vision from hemorrhagic disruption of cranial nerve nuclei III, IV, or VI in brainstem ICH, or from visual cortex disruption in posterior ICH; may require prism lenses, patching, or neuro-ophthalmology management.
- Visual field neglect/inattention: Reduced awareness of visual stimuli in the contralateral hemifield beyond formal field loss; may accompany posterior parietal ICH and affects functional performance in driving, reading, and spatial navigation tasks.
Tip
Manifestation coding pearl: I69.198 is a standalone sequela code — it does not require a “code first” instruction and does not follow the etiology/manifestation coding convention. The ICD-10-CM Includes notes do not function as “use additional code” instructions — they identify clinical conditions captured by this code, not additional codes to report alongside it. When central post-stroke pain is documented as a distinct condition separate from the sensory alteration, assign G89.29 additionally to fully represent the pain burden alongside I69.198.
💰 HCC Risk Adjustment
| Model | HCC Assignment | RAF Impact | Notes |
|---|---|---|---|
| CMS HCC V28 (MA) | None — not HCC-mapped | No independent RAF score | Sensory and visual ICH sequelae do not trigger HCC |
| CMS HCC V24 (legacy) | None — not HCC-mapped | No independent RAF score | ICH hemiplegia sequelae (I69.15x) carry HCC 103 |
| CDPS | Not applicable to inpatient DRG | N/A | N/A |
ICD-10 CM I69.198 carries no independent RAF value under CMS HCC Model V28, meaning it will not directly boost a patient’s risk score or drive MA plan reimbursement on its own. Despite this, accurate documentation and coding of I69.198 for sensory and visual post-ICH sequelae is clinically important — it captures the full neurological burden of the post-ICH patient and supports medical necessity for high-cost specialty services including neuro-ophthalmology, low vision rehabilitation, and neuropsychological evaluation. When the same ICH event also produced hemiplegia or hemiparesis, those codes (I69.151-I69.154) DO carry HCC 103 under V28 and must be coded alongside I69.198 when clinically supported — a patient with both hemisensory loss (I69.198) and hemiplegia (I69.151) following the same ICH should have both codes assigned to fully represent clinical complexity and capture available HCC value.
🏥 MS-DRG Assignment
| Sequencing Role | MCC Present | CC Present | Assigned DRG | MDC |
|---|---|---|---|---|
| Principal Diagnosis | Yes | N/A | DRG 056 — Degenerative Nervous System Disorders with MCC | MDC 01 |
| Principal Diagnosis | No | N/A | DRG 057 — Degenerative Nervous System Disorders without MCC | MDC 01 |
| Secondary Diagnosis | Varies | Varies | Driven by PDX; I69.198 CC/MCC status per FY2026 v43.0 grouper | MDC 01 |
When I69.198 is the principal diagnosis (e.g., patient admitted for inpatient rehabilitation evaluation of hemisensory loss or hemianopia as the primary deficit following prior nontraumatic ICH), it groups to MDC 01 under DRG 056 with MCC or DRG 057 without MCC for degenerative nervous system disorders. Always verify the FY2026 v43.0 grouper for current CC/MCC designations for I69.198 as a secondary diagnosis, as these classifications are updated annually with the IPPS final rule and directly impact DRG weight. For inpatient profee coders, principal diagnosis sequencing requires that the condition chiefly responsible for occasioning the admission be selected — when hemisensory loss or homonymous hemianopia from a prior nontraumatic ICH is the documented primary admission driver for rehabilitation, I69.198 earns PDX status over other comorbidities.

🛠️ Commonly Associated CPT Codes
NCCI Bundling Considerations
When billing for evaluation and management of post-ICH sensory and visual sequelae coded under I69.198, ensure that neuro-ophthalmology evaluation codes, low vision rehabilitation codes, and occupational therapy ADL retraining codes are billed by appropriate licensed providers with correct discipline modifiers. NCCI edits may bundle certain evaluation and therapeutic procedure codes when performed by the same provider on the same day — always reference the current NCCI table before billing multiple codes on the same DOS. Inpatient facility coders should note that specialty consults and therapy services are captured under the global DRG payment for the facility, while the profee side bills E/M or procedure codes separately for each provider’s individual services.
-
92083 — Visual field examination (unilateral or bilateral, with interpretation and report): Billed by ophthalmology or optometry when visual field testing is performed to document and quantify homonymous hemianopia or other visual field defects following nontraumatic ICH; required for establishing baseline deficit severity prior to low vision rehabilitation, driving evaluation, or disability documentation. I69.198 (disturbance of vision following nontraumatic ICH) supports medical necessity for this evaluation.
-
97129 — Therapeutic interventions focusing on cognitive function, first 15 minutes: Billed by OT or SLP when therapeutic interventions targeting sensory processing, visual attention, or visual-perceptual deficits following ICH are the primary focus; may be used for post-ICH hemispatial neglect with a visual component when cognitive strategy training is the intervention approach.
-
97530 — Therapeutic activities (15-minute timed units): Billed by OT for sensory-motor integration activities, visual-perceptual retraining, and functional ADL training addressing the impact of post-ICH sensory alteration or visual disturbance on daily activities; billed with -GO modifier for OT under Medicare.
-
97112 — Neuromuscular reeducation: Relevant when post-ICH sensory alteration causes proprioceptive deficits contributing to balance impairment, gait instability, or movement control problems; supports PT intervention targeting somatosensory-motor integration in the setting of hemisensory loss following ICH.
-
99244 — Office consultation, moderate complexity (outpatient): Billed by neuro-ophthalmology or low vision specialists when a formal consultation is performed for evaluation of post-ICH visual disturbances (hemianopia, diplopia, cortical visual impairment); I69.198 supports the consultation medical necessity when the visual disturbance is documented as a sequela of the prior nontraumatic ICH.
🔬 ICD-10-PCS Crosswalk
ICD-10-PCS codes capture inpatient procedures performed to address the conditions represented by I69.198 — no PCS code maps directly to a sensory alteration or visual disturbance diagnosis. The following PCS codes represent inpatient rehabilitation procedures most commonly documented in stays where I69.198 is a relevant diagnosis:
F09Z9ZZ — Assessment of Sensory Processing (Physical Rehabilitation and Diagnostic Audiology section): Used when a formal sensory processing assessment is performed during the inpatient stay to evaluate the nature and severity of post-ICH sensory alteration, establishing the baseline for rehabilitation planning and documenting the functional impact of hemisensory loss.
F07ZDZZ — Activities of Daily Living Treatment using Orthosis (Physical Rehabilitation section): Captures OT-directed ADL treatment that incorporates adaptive equipment or sensory compensation strategies to address functional limitations caused by post-ICH sensory alteration; applicable when sensory loss requires adaptive ADL retraining strategies during the inpatient rehabilitation stay.
F00ZXZZ — Assessment of Vision (Physical Rehabilitation and Diagnostic Audiology section): Used when a formal visual assessment is performed as part of the inpatient rehabilitation evaluation for disturbance of vision following ICH, documenting the visual field defect, diplopia, or cortical visual impairment before developing a visual rehabilitation plan.
F07Z8ZZ — Activities of Daily Living Treatment using Assistive Technology (Physical Rehabilitation section): Applicable when post-ICH visual disturbance (hemianopia, diplopia) requires integration of assistive technology into ADL training during the inpatient rehabilitation stay, such as prism glasses, scanning training, or visual compensation strategy training.
💊 Coding Scenarios and Examples
Scenario 1 — Inpatient Rehab Admission: Hemisensory Loss Post-ICH Ms. A, a 72-year-old female, is admitted to inpatient rehabilitation 5 weeks following a right thalamic nontraumatic intracerebral hemorrhage. The attending physiatrist documents left-sided hemisensory loss (impaired pain, temperature, and proprioception on the left), left-sided hemiparesis, and balance instability, all explicitly linked as sequelae of the prior thalamic ICH. She requires skilled PT, OT, and nursing care.
- Correct Coding: I69.198 (alteration of sensations/hemisensory loss — per Includes note), I69.152 (hemiplegia/hemiparesis following nontraumatic ICH, left dominant side — HCC 103), I69.193 (ataxia/balance instability following nontraumatic ICH)
- Sequencing: I69.152 as PDX if hemiparesis drives the admission; I69.198 and I69.193 as concurrent secondary sequela codes; do not omit I69.152 — it carries HCC 103
- CDI Note: Physiatrist must document each deficit with explicit causal language — “left hemisensory loss as sequela of right thalamic nontraumatic ICH” — not merely “thalamic stroke history, left numbness.”
Scenario 2 — Outpatient Neurology Follow-Up: Post-ICH Homonymous Hemianopia (Profee) Mr. C, a 64-year-old male, presents to neurology clinic 4 months after a right occipital nontraumatic intracerebral hemorrhage. The neurologist documents persistent left homonymous hemianopia impacting driving and reading, explicitly noted as a visual disturbance sequela of the prior right occipital ICH. Referral to neuro-ophthalmology is placed.
- Correct Coding: I69.198 (disturbance of vision — homonymous hemianopia — per Includes note, first-listed)
- Sequencing: I69.198 as first-listed outpatient diagnosis; neurologist’s explicit linkage phrase “left homonymous hemianopia as sequela of right occipital nontraumatic ICH” is the documentation anchor for compliant code assignment
- CDI Note: Documentation of “visual field cut” or “homonymous hemianopia” without explicit ICH linkage requires a physician query before I69.198 can be assigned — “visual field cut, history of ICH” is not sufficient per Guideline I.C.9.d.
Scenario 3 — Acute Inpatient Stay with Post-ICH Sensory/Visual Deficit as Comorbidity Mr. T is admitted for an elective knee replacement (M17.11). PMH includes nontraumatic ICH 2 years prior with residual right hemisensory loss (I69.198) and right homonymous hemianopia (also I69.198) documented as active comorbidities affecting fall risk assessment, positioning, and post-operative rehabilitation planning during the current admission.
- Correct Coding: M17.11 (PDX — primary osteoarthritis, right knee), I69.198 (sensory alteration AND visual disturbance — both Includes note categories captured under single code for same etiologic event)
- Sequencing: M17.11 as PDX; I69.198 as secondary comorbidity — must meet UHDDS criteria (documented as affecting care) to be reported; verify CC/MCC status per FY2026 v43.0 grouper
- CDI Note: When both sensory alteration and visual disturbance are present from the same prior nontraumatic ICH, a single I69.198 code captures both deficit categories — do not report I69.198 twice. If these deficits are from two separate cerebrovascular events (one ICH and one infarction), then both I69.198 and I69.398 may each be reported.
⚠️ Coding Pitfalls and Tips
- I69.198 is a catch-all of last resort — always verify specificity first. Before assigning I69.198, confirm that the documented post-ICH deficit is NOT apraxia (I69.190), dysphagia (I69.191), facial weakness (I69.192), or ataxia (I69.193). Using I69.198 when a more specific code exists is a specificity failure under the ICD-10-CM instruction to code to the highest level of specificity, and payers/auditors will flag it. I69.198 is appropriate when the documented deficit is sensory alteration, visual disturbance, or another truly unspecified post-ICH sequela not covered by the four specific codes.
- Never code I69.198 with an active acute ICH code simultaneously for the same event. I61.- codes represent the acute hemorrhagic phase; sequela codes are assigned after the acute phase resolves. These are mutually exclusive for the same event and coding both is a sequencing error that misrepresents the patient’s clinical timeline.
- Z86.73 and I69.198 cannot coexist. Z86.73 requires complete absence of residual deficits; any active sequela including sensory alteration or visual disturbance means Z86.73 is excluded by the Excludes 1 note at I69. This error is most common when a coder reflexively adds Z86.73 upon seeing “history of ICH” without checking whether active sequela codes are already assigned.
- One I69.198 can capture both sensory and visual sequelae from the same ICH event. Do not report I69.198 twice to capture both an alteration of sensation and a disturbance of vision when both stem from the same prior nontraumatic ICH — one code covers all “other specified” residuals from that event. Two instances of I69.198 would only be appropriate if they were attributable to two separate ICH events, which would be an extraordinary clinical scenario requiring explicit documentation.
- The causal documentation link is non-negotiable. “Hemisensory loss” or “hemianopia” charted in a patient with ICH history does not automatically authorize I69.198 — the provider must explicitly link the deficit to the prior nontraumatic ICH per Guideline I.C.9.d. Query the physician when causality is implied but not stated, particularly in inpatient profee coding where documentation-based audit exposure is highest.
- Do not overlook the HCC-bearing codes lurking alongside I69.198. The most consequential coding error with I69.198 is not misusing it — it is failing to also capture I69.151-I69.154 (hemiplegia/hemiparesis, HCC 103) when those deficits coexist with the sensory or visual sequelae from the same ICH. Sensory loss and hemianopia frequently accompany motor deficits in post-ICH patients; both the HCC-bearing and non-HCC codes must be assigned when supported by documentation.
