What is ICD-10 code I69.352?

I69.352 is the ICD-10-CM diagnosis code for Hemiplegia and hemiparesis following cerebral infarction affecting left dominant side. Weakness or paralysis affecting one entire side of the body (arm and leg together) on the left side after a stroke, in a person whose dominant side is the left. I69.352 is a billable code, meaning it can be reported on a claim as a primary or secondary diagnosis when supported by documentation. I69.352 is part of the FY2026 ICD-10-CM code set published by the CMS National Center for Health Statistics and used on Medicare, Medicaid, and commercial claims in the United States.

Yes. I69.352 is a billable ICD-10-CM code that can be reported on professional and institutional claims as a primary or secondary diagnosis when the provider documentation supports the specific condition described. Billable codes in ICD-10-CM are coded to the highest level of specificity available for the documented diagnosis. I69.352 is current for fiscal year 2026 and remains in the active CMS ICD-10-CM code set published by the National Center for Health Statistics.

Which HCC does I69.352 map to under V28?

I69.352 maps to CMS-HCC V28 HCC 253 (Hemiplegia/Hemiparesis). The category numbers, labels, and conditions come from the CMS-HCC V28 model file for payment year 2026.

What documentation supports I69.352?

Use I69.352 when the provider wording supports hemiplegia and hemiparesis following cerebral infarction affecting left dominant side. Check the FY2026 tabular notes and the full code path before the final code choice. For this DOS, capture the provider's current assessment and the care action documented for hemiplegia and hemiparesis following cerebral infarction affecting left dominant side. Keep the checklist tied to the note. Do not swap I69.352 with I69.351. The FY2026 tabular describes I69.351 as hemiplegia and hemiparesis following cerebral infarction affecting right dominant side. Follow the documented detail. Because I69.352 maps to an HCC category, the documentation must satisfy MEAT criteria (Monitor, Evaluate, Assess, or Treat) before the diagnosis is used for risk adjustment. See the MEAT criteria checklist at /meat-criteria for what Monitor, Evaluate, Assess, or Treat looks like in a note. MEAT is generic documentation evidence, not a payer-specific rule.

Buddy Documentation Tip

HCC Buddy guidance

Documentation of prior cerebral infarction (stroke) as the causative event with clear causal linkage to the current deficit

Confirmation that this is a sequela (late effect), not an acute or current cerebrovascular event

Description of hemiplegia or hemiparesis affecting one entire side of the body (both upper and lower extremities)

Current functional status and severity of the hemiplegia/hemiparesis (complete vs incomplete paralysis)

Audit Caution

HCC Buddy guidance

Using an acute cerebrovascular code (I60-I63) instead of a sequela code (I69) when the event occurred in a prior encounter

Coding monoplegia when both upper and lower limbs on the same side are affected — this should be coded as hemiplegia

Confusing hemiplegia (paralysis) with hemisensory loss or hemineglect, which require different codes

Incorrectly assigning dominant vs non-dominant side — if handedness is not documented, the default assumption is right-hand dominance per ICD-10-CM guidelines

Common Mistakes

HCC Buddy guidance

I69.1/I69.2/I69.8xx codes — sequelae of different cerebrovascular event types; must match the documented causative event

G81.x (Hemiplegia and hemiparesis, not specified as sequela) — use G81 when not a sequela of cerebrovascular disease

I69.x5x vs I69.x4x (Monoplegia of lower limb) — hemiplegia affects an entire side, not just one limb

Dominant vs non-dominant side codes — verify patient handedness; left-handed patients have left dominant side, right-handed have left non-dominant

Is I69.352 an HCC code?

Yes. I69.352 (Hemiplegia and hemiparesis following cerebral infarction affecting left dominant side) maps to HCC 253, Hemiplegia/Hemiparesis under the CMS-HCC V28 risk adjustment model, with a source-labeled community non-dual aged reference coefficient of 0.387. Source-labeled code-level coefficients are references, not member totals. Actual contribution depends on complete member context, hierarchy and cleanup rules, interactions, and model year. HCC Buddy's RAF Calculator supports CMS-HCC V28 PY2026 and shows no score unless every required source and calculation check passes. It is billable for payment year 2026.

Coder answer: I69.352 is billable and maps to V28 HCC 253, Hemiplegia/Hemiparesis. Open it in the Code Book for the tabular path, RAF, and MEAT checklist.

These are source-labeled model coefficients, not member totals. A category may still be removed by hierarchy or model cleanup rules. Weights are not directly comparable across models: CMS-HCC V28 and V24 use Community, Non-Dual, Aged; ESRD uses the dialysis continuing-enrollee model; RxHCC is the Part D continuing-enrollee, non-low-income, aged weight (a larger scale than CMS-HCC). ACA/HHS has no single weight — it varies by metal level. Actual per-patient RAF contribution depends on member context, hierarchy and cleanup rules, interactions, and the model year used by the payer. V28 is the CMS-HCC model phased in over payment years 2024–2026; V24 remains available for historical review.

MEAT Criteria for I69.352

For I69.352 to count as a valid HCC diagnosis in a given encounter, the provider's documentation must show MEAT: Monitor, Evaluate, Assess, or Treat. A diagnosis from a prior year does not carry forward automatically, it has to be re-documented and supported each calendar year.

MMonitor: signs, symptoms, disease progression, or lab trending documented in the note
EEvaluate: test results, medication response, or physical findings reviewed by the provider
AAssess: explicit mention in the assessment or plan with acknowledgment of status
TTreat: medication, referral, procedure, therapy, or counseling tied to the diagnosis

Only one of M/E/A/T is required to support the code, but the documentation must be specific enough to show that the provider actually addressed I69.352 during that encounter, not just copy-forwarded from a problem list.

What This Code Means

I69.352 is the ICD-10-CM diagnosis code for hemiplegia and hemiparesis following cerebral infarction affecting left dominant side. Weakness or paralysis affecting one entire side of the body (arm and leg together) on the left side after a stroke, in a person whose dominant side is the left. I69.352 sits in the ICD-10-CM chapter for diseases of the circulatory system (i00-i99), within the section covering cerebrovascular diseases (i60-i69).

Under the CMS-HCC V28 risk adjustment model, I69.352 maps to Hemiplegia/Hemiparesis (HCC 253) with a source-labeled community, non-dual, aged reference coefficient of 0.387. No V24 mapping is shown for I69.352; use the applicable model and payment year when reviewing the V28 mapping. V28 is the CMS-HCC risk adjustment model that reached 100% phase-in for payment year 2026, replacing V24 which was used during the PY2024–PY2025 transition. Source-labeled code-level coefficients are references, not member totals. Actual contribution depends on complete member context, hierarchy and cleanup rules, interactions, and model year. HCC Buddy's RAF Calculator supports CMS-HCC V28 PY2026 and shows no score unless every required source and calculation check passes.

Use I69.352 when the provider wording supports hemiplegia and hemiparesis following cerebral infarction affecting left dominant side. Check the FY2026 tabular notes and the full code path before the final code choice. Because I69.352 maps to an HCC category, the provider's documentation must satisfy MEAT criteria (Monitor, Evaluate, Assess, or Treat) before the diagnosis is used for risk adjustment. When documentation is ambiguous, coders should issue a provider query rather than assume the highest-specificity variant.

HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for I69.352 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.

Coding Tips

•Use I69.352 when the provider wording supports hemiplegia and hemiparesis following cerebral infarction affecting left dominant side. Check the FY2026 tabular notes and the full code path before the final code choice.
•For this DOS, capture the provider's current assessment and the care action documented for hemiplegia and hemiparesis following cerebral infarction affecting left dominant side. Keep the checklist tied to the note.
•Do not swap I69.352 with I69.351. The FY2026 tabular describes I69.351 as hemiplegia and hemiparesis following cerebral infarction affecting right dominant side. Follow the documented detail.
•I69.352 maps to V28 HCC 253, Hemiplegia/Hemiparesis. The mapping does not replace the documentation review. The code still has to match the note.
•Ask Buddy to show the official notes for I69.352 or compare its code path with I69.351.

Clinical Significance

Hemiplegia and hemiparesis as a sequela of a cerebral infarction (ischemic stroke) represents a chronic neurological deficit that significantly impacts the patient's functional status and ongoing care needs. Hemiplegia involves paralysis or significant weakness affecting one entire side of the body, requiring ongoing rehabilitation, fall prevention strategies, and often assistive devices for activities of daily living. This condition is a key risk adjustment indicator as it reflects severe neurological damage with high resource utilization for therapy, home health, and durable medical equipment.

Documentation Requirements

✓Documentation of prior cerebral infarction (stroke) as the causative event with clear causal linkage to the current deficit
✓Confirmation that this is a sequela (late effect), not an acute or current cerebrovascular event
✓Description of hemiplegia or hemiparesis affecting one entire side of the body (both upper and lower extremities)
✓Current functional status and severity of the hemiplegia/hemiparesis (complete vs incomplete paralysis)
✓Documentation of which side is affected (right or left)
✓Documentation of patient's hand dominance to determine dominant vs non-dominant classification
✓Current treatment plan including rehabilitation services, medications, and adaptive equipment
✓Assessment that the condition is being actively monitored or managed during the encounter

Commonly Confused Codes

•I69.1/I69.2/I69.8xx codes: sequelae of different cerebrovascular event types; must match the documented causative event
•G81.x (Hemiplegia and hemiparesis, not specified as sequela): use G81 when not a sequela of cerebrovascular disease
•I69.x5x vs I69.x4x (Monoplegia of lower limb): hemiplegia affects an entire side, not just one limb
•Dominant vs non-dominant side codes: verify patient handedness; left-handed patients have left dominant side, right-handed have left non-dominant
