Question 1

What is ICD-10 code I69.328?

Accepted Answer

I69.328 is the ICD-10-CM diagnosis code for other speech and language deficits following cerebral infarction. Various speech and language problems (such as difficulty finding words or understanding speech) that occur as a lasting effect of a stroke. I69.328 sits in the ICD-10-CM chapter for diseases of the circulatory system (i00-i99), within the section covering cerebrovascular diseases (i60-i69).

I69.328 is a billable ICD-10-CM code, but the current payload does not show a mapping under the CMS-HCC V28, V24, ESRD, or RxHCC models. Do not assign risk adjustment value from this page when no source-backed mapping is shown; verify the applicable model and payment year.

Use this code for speech deficits not specifically classified as fluency disorder, aphasia, or dysarthria.

Question 2

Is I69.328 an HCC code?

Accepted Answer

No. I69.328 is a billable ICD-10-CM code but does not map to any payment HCC category under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can still be reported on Medicare Advantage encounter data submissions, but it does not contribute to the beneficiary's Risk Adjustment Factor (RAF) score and therefore does not affect the risk-adjusted capitation payment to the plan. V28 reached 100% phase-in for payment year 2026.

Question 3

Is I69.328 billable?

Accepted Answer

Yes. I69.328 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. I69.328 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.

Question 4

Which HCC does I69.328 map to under V28?

Accepted Answer

I69.328 does not map to a CMS-HCC V28 payment category. Check the current CMS-HCC V28 model file for payment year 2026 rather than an older V24 tip sheet.

Question 5

What RAF reference is published for I69.328?

Accepted Answer

I69.328 has no separately stated V28 community reference coefficient. Check the current CMS mapping and factor files before using it in any member-score workflow.

Question 6

What is the V28 vs V24 difference for I69.328?

Accepted Answer

I69.328 does not map to a payment HCC under either the CMS-HCC V28 risk adjustment model or the older V24 model. V28 reached 100% phase-in for payment year 2026, replacing V24 which was used during the PY2024–PY2025 transition. Because neither community model rewards I69.328 with a risk adjustment factor, it contributes zero to a Medicare Advantage beneficiary's V28/V24 community RAF score in either version. Coders should check whether provider documentation supports a more specific child code that does map to a community payment HCC.

Question 7

What documentation supports I69.328?

Accepted Answer

Use this code for speech deficits not specifically classified as fluency disorder, aphasia, or dysarthria Document the specific type of speech/language deficit in the medical record for clarity and potential future specificity I69.328 is not a CMS-HCC payment code, so MEAT is not the payment hook. Documentation still has to support the diagnosis if you report it.
