What is ICD-10 code I69.169?

I69.169 is the ICD-10-CM diagnosis code for Other paralytic syndrome following nontraumatic intracerebral hemorrhage affecting unspecified side. Other types of muscle weakness or paralysis resulting from brain bleeding when the specific side affected is not documented. I69.169 is a billable code, meaning it can be reported on a claim as a primary or secondary diagnosis when supported by documentation. I69.169 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. I69.169 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. I69.169 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.

What is the V28 vs V24 difference for I69.169?

CMS phased in the V28 risk adjustment model over payment years 2024 (33%), 2025 (67%), and 2026 (100%), replacing V24. V28 consolidates HCC categories, removes some lower-acuity conditions, and recalibrates RAF weights across the entire model. For I69.169, V28 maps to Monoplegia, Other Paralytic Syndromes at RAF 0.000 while V24 mapped to Monoplegia, Other Paralytic Syndromes at RAF 0.304. Both models can still appear in legacy data and in payer-specific lookback periods.

What should coders know when reporting I69.169?

This is a residual code when laterality is unknown or unspecified Query provider for clarification on affected side(s) when documentation is unclear Because I69.169 maps to a payment HCC, the documentation must also satisfy MEAT criteria (Monitor, Evaluate, Assess, or Treat) for the encounter to count toward the patient's risk adjustment score.

Buddy Documentation Tip

HCC Buddy guidance

Documentation of prior nontraumatic intracerebral hemorrhage 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

Specific description of the paralytic syndrome that does not fit monoplegia or hemiplegia categories

Current functional status and extent of paralytic involvement

MEAT Support

Documentation of prior nontraumatic intracerebral hemorrhage as the causative event with clear causal linkage to the current deficit

Specific description of the paralytic syndrome that does not fit monoplegia or hemiplegia categories

Current functional status and extent of paralytic involvement

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

Using 'other paralytic syndrome' when a more specific code for monoplegia or hemiplegia is available and documented

Failing to document the specific nature of the paralytic syndrome, making it difficult to validate the code

Defaulting to unspecified laterality without querying the provider — laterality and dominance should be documented whenever possible for specificity

Common Mistakes

HCC Buddy guidance

I69.2/I69.3/I69.8xx codes — sequelae of different cerebrovascular event types; must match the documented causative event

G83.9 (Paralytic syndrome, unspecified) — use when not a sequela of cerebrovascular disease

I69.x5x (Hemiplegia/hemiparesis) — use when paralysis specifically fits the hemiplegia pattern affecting one side

Laterality-specific codes in the same subcategory — query provider for affected side and dominance before defaulting to unspecified

Last updated: FY2026 ICD-10-CM Apr update, Apr 1, 2026 through Sep 30, 2026. CMS-HCC V28 is 100% phased in for payment year 2026.

Is I69.169 an HCC code?

Yes. I69.169 maps to Monoplegia, Other Paralytic Syndromes under the CMS-HCC V28 risk adjustment model (and Monoplegia, Other Paralytic Syndromes under V24).

RAF weights shown are the community, non-dual, aged base weights from the CMS risk adjustment model file. Actual per-patient RAF contribution depends on member segment, interactions, and the model year used by the payer. V28 is the CMS-HCC model phased in over payment years 2024–2026; V24 remains in use during the transition and for historical data.

MEAT Criteria for I69.169

For I69.169to 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 I69.169 during that encounter, not just copy-forwarded from a problem list.

What This Code Means

I69.169 is the ICD-10-CM diagnosis code for other paralytic syndrome following nontraumatic intracerebral hemorrhage affecting unspecified side. Other types of muscle weakness or paralysis resulting from brain bleeding when the specific side affected is not documented. I69.169 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, I69.169 maps to Monoplegia, Other Paralytic Syndromes (HCC 254) with a community, non-dual, aged base RAF weight of 0.000. Under the older V24 model, I69.169 mapped to the same category but with a base RAF weight of 0.304, V28 recalibrated weights across the entire model. 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.

This is a residual code when laterality is unknown or unspecified. Because I69.169 maps to a payment HCC, the provider's documentation must satisfy MEAT criteria (Monitor, Evaluate, Assess, or Treat) for the encounter to count toward the patient's Medicare Advantage risk adjustment score. 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, RAF weights, and MEAT documentation criteria for I69.169 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.

Coding Tips

•This is a residual code when laterality is unknown or unspecified
•Query provider for clarification on affected side(s) when documentation is unclear

Clinical Significance

Other paralytic syndrome as a sequela of a nontraumatic intracerebral hemorrhage (brain bleed within the brain parenchyma) represents a chronic neurological deficit that significantly impacts the patient's functional status and ongoing care needs. This category captures paralytic syndromes that do not fit the specific monoplegia or hemiplegia patterns, such as locked-in syndrome, quadriplegia following stroke, or other complex motor deficits. These conditions represent significant risk adjustment value as they indicate severe neurological compromise with substantial ongoing care requirements.

Documentation Requirements

✓Documentation of prior nontraumatic intracerebral hemorrhage 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
✓Specific description of the paralytic syndrome that does not fit monoplegia or hemiplegia categories
✓Current functional status and extent of paralytic involvement
✓Affected side should be specified when possible; query the provider if laterality is not documented
✓Current treatment plan including rehabilitation services, medications, and adaptive equipment
✓Assessment that the condition is being actively monitored or managed during the encounter
