Mixed lesions of pinta

This code represents the late-stage manifestation of pinta, a chronic treponemal infection, characterized by a combination of dyschromic skin lesions. These lesions typically include hyperpigmented (darker), hypopigmented (lighter), and atrophic (thinned) areas, often appearing simultaneously or in various stages of evolution. It signifies the progression of the disease beyond the early primary and secondary stages.

Use this code when documentation clearly indicates the presence of mixed skin lesions consistent with late-stage pinta. This diagnosis is typically made clinically based on the characteristic skin changes and a history of exposure in endemic areas, often confirmed by serological tests for treponemal antibodies. It is appropriate when the patient presents with a combination of the distinct lesion types associated with chronic pinta.

• Ensure documentation specifies "mixed lesions" or describes the presence of both hyperpigmented and hypopigmented/atrophic patches to support this specific code.
• Differentiate from earlier stages of pinta (e.g., primary or secondary lesions) which have distinct ICD-10-CM codes.
• Consider co-reporting codes for any associated complications or sequelae if documented.
