Pruritus (L29)
The ICD-10 codes starting with L29 cover various types of pruritus, which means itching of the skin. These codes help specify the exact location and cause of itching, such as around the anus, genital organs, or due to systemic conditions.
This section includes general pruritus (L29) and more specific diagnoses like pruritus ani (L29.0), which refers to itching of the skin near the anus, also known as pruritis of the anogenital region. Codes like L29.1 and L29.2 describe itching of the male and female genital organs, respectively, using terms such as scrotal pruritus or pruritus vulvae. L29.3 addresses unspecified anogenital pruritus, which covers irritation or itching in the perineal and genital skin areas. Other codes include cholestatic pruritus (L29.81), related to liver conditions causing itching, and L29.89 for less common types such as brachioradial summer pruritus or aquagenic pruritus. When the cause or location of itching is unclear, L29.9 is used for unspecified pruritus, which also includes itching linked to systemic illnesses, drug reactions, or neurological disorders. Understanding these distinctions helps healthcare professionals accurately code and communicate the nature of pruritus in patient records.
