About ICD-10-CM L81
ICD-10-CM code L81 represents Other disorders of pigmentation. This is a non-billable header code in the Skin and Subcutaneous Tissue chapter (block L81). The 2026 edition of ICD-10-CM L81 became effective on October 1, 2025. Non-billable codes cannot be used as a primary or secondary diagnosis on a claim, use a more specific child code instead.
Type 1 Excludes
Pure excludes, these codes can never be coded together with L81. The conditions are mutually exclusive (e.g., congenital vs acquired forms).
- birthmark NOS (Q82.5)
- Peutz-Jeghers syndrome (Q85.89)
Type 2 Excludes
Not included here, the excluded code is not part of L81, but a patient may have both conditions at the same time. Both codes may be coded together when applicable.
