L81 — Other disorders of pigmentation

Non-billable headerICD-10-CM

L81 is a non-billable header ICD-10-CM code for other disorders of pigmentation. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

birthmark NOS (Q82.5)
Peutz-Jeghers syndrome (Q85.89)

Excludes2 — not included here, but may coexist

The excluded condition is not part of this code, but a patient can have both. You may code both.

nevus - see Alphabetical Index

Other codes that can never be billed with L81

These codes carry an Excludes1 note pointing at L81. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading L81 alone.

L95Vasculitis limited to skin, not elsewhere classified

Risk adjustment

L81 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Code to one of these instead L81

10 child codes. Green means billable.
