What This Code Means
B36.0 is the ICD-10-CM diagnosis code for pityriasis versicolor. A common fungal skin infection that causes patches of discolored skin, typically appearing as lighter or darker areas on the chest, back, or neck. It's caused by a yeast-like fungus and is also known as tinea versicolor. B36.0 sits in the ICD-10-CM chapter for certain infectious and parasitic diseases (a00-b99), within the section covering mycoses (b35-b49).
B36.0 is a billable ICD-10-CM code, but the current payload does not show a mapping under the CMS-HCC V28 or V24 community payment models, and none under the ESRD, Part D RxHCC, or HHS-HCC models. Do not assign risk adjustment value from this page when no source-backed mapping is shown; verify the applicable model and payment year.
This condition is caused by Malassezia species, not dermatophytes, so it should not be coded with B35 codes.
HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for B36.0 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •This condition is caused by Malassezia species, not dermatophytes, so it should not be coded with B35 codes
- •Document whether the condition is active or in remission, as this may affect treatment decisions
