What is ICD-10 code I69.162?

I69.162 is the ICD-10-CM diagnosis code for Other paralytic syndrome following nontraumatic intracerebral hemorrhage affecting left dominant side. Other types of muscle weakness or paralysis (beyond hemiplegia) on the left dominant side resulting from brain bleeding. I69.162 is a billable code, meaning it can be reported on a claim as a primary or secondary diagnosis when supported by documentation. I69.162 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. I69.162 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. I69.162 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 I69.162?

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 I69.162, 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 I69.162?

Confirm dominance is documented in the medical record; left dominance is less common but should be clearly stated Link the paralytic syndrome to the intracerebral hemorrhage event in documentation Because I69.162 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

Clear documentation of other paralytic syndrome as a current, active condition (not just in the patient's history)

Documentation explicitly linking the paralytic deficit to a prior nontraumatic intracerebral hemorrhage

Specification of affected side and dominance (right dominant, left dominant, right non-dominant, left non-dominant)

Current functional assessment documenting the severity and impact on activities of daily living

MEAT Support

Audit Caution

HCC Buddy guidance

Coding an acute intracerebral hemorrhage code (I61.x) instead of the sequela code (I69.1x) — sequelae codes are for residual deficits, not the acute event

Confusing intracerebral hemorrhage sequelae (I69.1x) with subarachnoid hemorrhage sequelae (I69.0x) or cerebral infarction sequelae (I69.3x)

Failing to specify laterality and dominance — the 5th and 6th characters capture this critical clinical detail

Not recapturing the sequela code annually — these chronic deficits must be reported each year they persist and are actively managed

Common Mistakes

HCC Buddy guidance

I69.13x — Monoplegia of upper limb following nontraumatic intracerebral hemorrhage; use for single upper limb paralysis

I69.14x — Monoplegia of lower limb following nontraumatic intracerebral hemorrhage; use for single lower limb paralysis

I69.15x — Hemiplegia/hemiparesis following nontraumatic intracerebral hemorrhage; use for one-sided paralysis

I69.06x — Other paralytic syndrome following nontraumatic subarachnoid hemorrhage; different type of hemorrhagic stroke

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 I69.162 an HCC code?

Yes. I69.162 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 I69.162

For I69.162to 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 I69.162 during that encounter, not just copy-forwarded from a problem list.

What This Code Means

I69.162 is the ICD-10-CM diagnosis code for other paralytic syndrome following nontraumatic intracerebral hemorrhage affecting left dominant side. Other types of muscle weakness or paralysis (beyond hemiplegia) on the left dominant side resulting from brain bleeding. I69.162 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, I69.162 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, I69.162 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.

Confirm dominance is documented in the medical record; left dominance is less common but should be clearly stated. Because I69.162 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 I69.162 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.

Coding Tips

•Confirm dominance is documented in the medical record; left dominance is less common but should be clearly stated
•Link the paralytic syndrome to the intracerebral hemorrhage event in documentation

Clinical Significance

This code captures other paralytic syndrome (left dominant side) as a late effect of prior nontraumatic intracerebral hemorrhage. Other paralytic syndromes following intracerebral hemorrhage may include quadriplegia, locked-in syndrome, or complex multi-limb paralytic patterns. These represent severe neurological sequelae with high care requirements, and accurate coding ensures appropriate risk adjustment for the ongoing management burden.

Documentation Requirements

✓Clear documentation of other paralytic syndrome as a current, active condition (not just in the patient's history)
✓Documentation explicitly linking the paralytic deficit to a prior nontraumatic intracerebral hemorrhage
✓Specification of affected side and dominance (right dominant, left dominant, right non-dominant, left non-dominant)
✓Current functional assessment documenting the severity and impact on activities of daily living
✓Ongoing treatment plan including rehabilitation services, medications, and assistive devices
✓Documentation that the original stroke was an intracerebral hemorrhage (bleeding within the brain tissue) — not subarachnoid hemorrhage or cerebral infarction
