Striae atrophicae

This code represents atrophic linear streaks or bands on the skin, commonly known as stretch marks. These lesions are characterized by thinning of the epidermis and dermis, often appearing as reddish or purple initially, then fading to white or silvery over time. They result from rapid stretching of the skin, leading to tears in the dermis.

Use this code for documented cases of striae atrophicae, regardless of their etiology (e.g., pregnancy, rapid weight gain/loss, corticosteroid use, Cushing's syndrome). Documentation should clearly identify the presence of stretch marks. This code is appropriate when the striae are the primary reason for the encounter or a significant co-morbidity.

• Do not confuse with other skin lesions or scars; ensure documentation specifically mentions "striae" or "stretch marks."
• If the striae are a manifestation of an underlying systemic condition (e.g., Cushing's syndrome), code the underlying condition first, followed by this code.
• This code does not differentiate by body site; it's a general code for atrophic striae.
