ICD-10 Code L75.1 – Chromhidrosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L75.1 – Chromhidrosis
What it is
Chromhidrosis is a condition in which sweat is colored, usually from pigment-producing glands. You should use this code when documentation identifies true colored perspiration rather than staining from outside sources.
Clinical signs
Patients may have visibly colored sweat on the skin, clothing, or bedding. Clinical features vary; refer to documentation, and confirm that the discoloration is due to sweat secretion.
When to use this code
Use L75.1 when the record states chromhidrosis or describes colored sweat as the diagnosis. It may also fit when a clinician documents apocrine or eccrine chromhidrosis, if clearly identified. Check documentation if the color change is only suspected or not confirmed.
Do not use for
Do not use this code for skin staining from dyes, medications, or environmental exposure. It is also not appropriate for generalized sweating disorders without documented colored sweat.
Coding tip
Look for explicit wording that the sweat itself is colored; if the source is unclear, query the provider.
