Other spirochetal diseases (A65-A69)

ICD-10 codes A65 through A69 classify various spirochetal infections, a group of bacterial diseases characterized by spiral-shaped bacteria. These codes cover conditions like nonvenereal syphilis, yaws, pinta, relapsing fevers, Lyme disease, and other specified or unspecified spirochetal infections.

This range includes A65 for nonvenereal syphilis, also known by terms like Bejel or Sibbens. The category A66 details yaws, a tropical infection with multiple stages and symptoms, with distinct codes for initial lesions, papillomata, hyperkeratosis, and bone involvement. Pinta (A67) codes cover its skin lesions from primary to late stages. The relapsing fevers (A68) distinguish between louse-borne and tick-borne causes, both linked to Borrelia species. Lyme disease is detailed under A69.2, with subcodes specifying neurological effects, arthritis, and other complications. Other codes in A69 cover necrotizing ulcerative stomatitis (cancrum oris), Vincent's infections, and other spirochetal infections caused by Borrelia or Treponema species. Using these precise codes ensures accurate recording and diagnosis of specific spirochetal illnesses encountered globally.

Instructional Notations

Type 2 Excludes

A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.
