ICD-10 Code L81 – Other disorders of pigmentation (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L81 – Other disorders of pigmentation
What it is
L81 covers noninfectious disorders of skin pigmentation that do not fit a more specific ICD-10 code. Use it when the record documents abnormal skin color changes, but the exact pigment disorder is not named.
Clinical signs
Findings may include hyperpigmentation, hypopigmentation, or mixed pigment change on the skin. Clinical features vary; refer to documentation for the specific pattern, cause, and body area involved.
When to use this code
Use L81 when the clinician documents an unspecified or other pigment disorder, such as generalized or localized color change without a more precise diagnosis. It also fits when the note confirms pigmentation abnormality but does not identify vitiligo, melasma, or another specific condition. Check documentation if the cause is unclear.
Do not use for
Do not use L81 when the chart supports a more specific pigmentation diagnosis or a skin disorder with pigment change as part of its definition. Do not use it for temporary discoloration, bruising, or postinflammatory changes unless documented as an actual pigment disorder.
Coding tip
Look for the exact pigment diagnosis in the assessment; if the provider only writes “pigmentation disorder,” L81 is usually the best match.
