Other predominantly sexually transmitted diseases, not elsewhere classified (A63)

ICD-10 code A63 covers sexually transmitted diseases that do not fit into other specific categories, with detailed subcodes like A63.0 and A63.8 addressing particular infections such as anogenital warts and various balanitis conditions. These codes are important for accurately classifying less common or unspecified sexually transmitted infections.

The ICD-10 code for anogenital (venereal) warts, A63.0, includes conditions commonly known as genital warts, anal warts, or condyloma acuminata of the vulva and other anogenital regions. This code is used to identify infections caused by human papillomavirus (HPV) presenting as warty growths in the genital and anal areas. Terms like "vulval warts," "perianal warts," and "urethral wart" all fall under this code, helping coders link these synonyms back to the official classification. On the other hand, A63.8 specifies other predominantly sexually transmitted diseases such as bacterial and anaerobic balanitis or ulcerative balanoposthitis, which are infections that affect the male genitalia and do not have separate specific codes elsewhere. Together, these codes enable precise documentation of sexually transmitted infections that are less frequently encountered or do not fit standard categories in clinical records.
