About coding acne rosacea
The ICD-10-CM code for acne rosacea is L71.9 (Rosacea, unspecified).
Within L71, choose L71.9 (unspecified) only when documentation doesn't support a more specific option: Perioral dermatitis (L71.0), Rhinophyma (L71.1) and other rosacea (L71.8).
Use an additional code for adverse effect, if applicable, to identify drug (T36-T50 with fifth or sixth character 5).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
