L25
L25 — Unspecified contact dermatitis
Non-billable headerICD-10-CM
L25 is a non-billable header ICD-10-CM code for unspecified contact dermatitis. 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.
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.
Other codes that can never be billed with L25
These codes carry an Excludes1 note pointing at L25. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading L25 alone.
Risk adjustment
L25 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.
