L22 — Diaper dermatitis
L22 is a billable, specific ICD-10-CM code for diaper dermatitis. It is valid for submission on a claim.
Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Diaper erythema
- Diaper rash
- Psoriasiform diaper rash
Other codes that can never be billed with L22
These codes carry an Excludes1 note pointing at L22. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading L22 alone.
- L24.A2Irritant contact dermatitis due to fecal, urinary or dual incontinence
Risk adjustment
L22 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.
How L22 is indexed
Coders do not find codes by browsing the tabular list — they look them up in the alphabetic index, under the word the physician wrote. These are the index entries that lead here, so you can see which chart wordings map to L22.
