ICD-10 Code L90.6 – Striae atrophicae (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L90.6 – Striae atrophicae
What it is
Striae atrophicae are linear, depressed stretch marks in the skin. They usually reflect dermal thinning after stretching, growth, pregnancy, weight change, or corticosteroid exposure.
Clinical signs
Look for parallel bands that may be pink, red, purple, or silvery-white as they mature. They are commonly found on the abdomen, thighs, hips, breasts, or upper arms; clinical features vary, refer to documentation.
When to use this code
Use L90.6 when the record clearly identifies striae atrophicae or stretch marks as the diagnosis. This code fits outpatient, dermatology, or primary care documentation when the provider is treating or assessing the striae themselves. Check documentation if the note only mentions body changes without naming the condition.
Do not use for
Do not use this code for skin tears, scars, or other atrophic skin disorders unless the provider documents striae atrophicae. If the finding is unspecified, check documentation.
Coding tip
Code only when the provider documents striae atrophicae or an equivalent term such as stretch marks.
