Striae atrophicae

This code represents atrophic linear streaks or bands on the skin, commonly known as stretch marks. These lesions result from the stretching of the dermis, leading to a loss of elastic tissue and collagen. They typically appear as reddish or purplish lines initially, eventually fading to a white or silvery, depressed appearance.

Use this code when documentation specifies the presence of striae atrophicae, often seen after rapid weight changes (gain or loss), pregnancy, adolescent growth spurts, or prolonged corticosteroid use. The diagnosis should clearly indicate the atrophic nature of the striae.

• Differentiate from other skin atrophy codes if the documentation does not specifically mention striae.
• Do not use for hypertrophic scars or keloids, which are distinct conditions.
• Consider an additional code for the underlying cause (e.g., pregnancy, Cushing's syndrome) if documented and relevant.
