What This Code Means
B35.8 is the ICD-10-CM diagnosis code for other dermatophytoses. A fungal infection of the skin caused by dermatophytes (fungi that infect skin, hair, or nails) that doesn't fit into other specific categories. This includes various types of ringworm and similar fungal skin conditions. B35.8 sits in the ICD-10-CM chapter for certain infectious and parasitic diseases (a00-b99), within the section covering mycoses (b35-b49).
B35.8 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 specific type of dermatophytosis cannot be identified or is not listed in other B35 codes.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for B35.8 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 specific type of dermatophytosis cannot be identified or is not listed in other B35 codes
- •Document the location of the infection (e.g., scalp, body, feet) as this may affect treatment and require additional codes
