Question 1

What is ICD-10 code H47.632?

Accepted Answer

H47.632 is the ICD-10-CM diagnosis code for Disorders of visual cortex in (due to) neoplasm, left side of brain. It belongs to the ICD-10-CM chapter for diseases of the eye and adnexa (h00-h59). H47.632 is a billable code, meaning it can be reported on a claim as a primary or secondary diagnosis when supported by documentation. H47.632 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.

Question 2

Is H47.632 an HCC code?

Accepted Answer

No. H47.632 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 H47.632 billable?

Accepted Answer

Yes. H47.632 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. H47.632 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 H47.632 map to under V28?

Accepted Answer

H47.632 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 does H47.632 pay in RAF?

Accepted Answer

H47.632 has no separately stated V28 community RAF weight. If it is not a V28 payment HCC, it adds nothing to a community RAF score.

Question 6

What is the V28 vs V24 difference for H47.632?

Accepted Answer

H47.632 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 H47.632 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 H47.632?

Accepted Answer

Always verify the neoplasm is confirmed to be affecting the visual cortex and specify laterality (left side) in documentation before coding This code requires a secondary code to identify the specific neoplasm (C-code) causing the visual cortex disorder; do not use this code alone H47.632 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.
