L30

L30 — Other and unspecified dermatitis

Non-billable headerICD-10-CM

L30 is a non-billable header ICD-10-CM code for other and unspecified dermatitis. It cannot be billed on its own: choose one of the more specific child codes below.

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.

contact dermatitis (L23-L25)
dry skin dermatitis (L85.3)
small plaque parapsoriasis (L41.3)
stasis dermatitis (I87.2)

Other codes that can never be billed with L30

These codes carry an Excludes1 note pointing at L30. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading L30 alone.

L23Allergic contact dermatitis
L24Irritant contact dermatitis
L25Unspecified contact dermatitis
L53Other erythematous conditions
L75Apocrine sweat disorders

Risk adjustment

L30 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 L30

8 child codes. Green means billable.
