Is L01.0 a billable ICD-10-CM code?

No. L01.0 is a non-billable header code. Code to a higher level of specificity using one of its child codes.

Where does L01.0 sit in the tabular list?

Diseases of the skin and subcutaneous tissue (L00-L99), in the block Infections of the skin and subcutaneous tissue (L00-L08).

What cannot be coded together with L01.0?

L01.0 carries Excludes1 notes, which means the conditions they list can never be coded together with it on the same encounter. Some are written on the categories above L01.0 (L01) and apply to it just the same.

Inclusion terms

Alternative wordings a physician may use in the chart for this same code.

Impetigo contagiosa
Impetigo vulgaris

Excludes1 inherited from the categories above L01.0

These are not written on L01.0, but they bind it: a note on a category applies to every code beneath it. Billing L01.0 with anything listed here is a denial.

Written on L01 — Impetigo

impetigo herpetiformis (L40.1)

Other codes that can never be billed with L01.0

These codes carry an Excludes1 note pointing at L01.0. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading L01.0 alone.

L00Staphylococcal scalded skin syndrome
L10Pemphigus

Risk adjustment

L01.0 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 history

L01.0 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.

Code to one of these instead L01.0

5 child codes. Green means billable.
