Is B41.8 an HCC code?
No. B41.8 is a billable ICD-10-CM code but does not map to any HCC category in V28, V24, ESRD, or RxHCC.
This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).
What This Code Means
B41.8 is the ICD-10-CM diagnosis code for other forms of paracoccidioidomycosis. This code represents a fungal infection caused by Paracoccidioides brasiliensis that doesn't fit into the more common forms of the disease. It's a rare infection primarily found in Central and South America that affects the lungs and can spread to other parts of the body. B41.8 sits in the ICD-10-CM chapter for certain infectious and parasitic diseases (a00-b99), within the section covering mycoses (b35-b49).
B41.8 is a billable ICD-10-CM code but does not map to a payment HCC under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can be reported on Medicare Advantage encounter data submissions but it does not contribute to a beneficiary's RAF score and therefore does not affect risk-adjusted payments to the plan.
Use this code only when the paracoccidioidomycosis cannot be classified as the acute/primary form (B41.0), chronic form (B41.1), or disseminated form (B41.7).
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for B41.8 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Use this code only when the paracoccidioidomycosis cannot be classified as the acute/primary form (B41.0), chronic form (B41.1), or disseminated form (B41.7)
- •Verify documentation specifies the affected body system or organ involvement, as this helps justify the 'other forms' classification and may support medical necessity for treatment
