Excludes1 inherited from the categories above L02.22

These are not written on L02.22, but they bind it: a note on a category applies to every code beneath it. Billing L02.22 with anything listed here is a denial.

non-newborn omphalitis (L08.82)
omphalitis of newborn (P38.-)

Excludes2 inherited from the categories above L02.22

Also inherited, and the opposite of Excludes1: these conditions are not part of L02.22, but a patient can have both, so you may code both.

abscess of breast (N61.1)
abscess of buttocks (L02.3)
abscess of female external genital organs (N76.4)

Risk adjustment

L02.22 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.

L02.22 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 L02.22
