About coding Nonbullous impetigo
The ICD-10-CM code for Nonbullous impetigo is L01.01 (Non-bullous impetigo).
Within L01.0 (impetigo), L01.01 is specifically for Non-bullous impetigo. Related codes cover unspecified (L01.00), Bockhart's impetigo (L01.02), bullous impetigo (L01.03) and other impetigo (L01.09).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
In MS-DRG v44.0, it is part of the grouping logic for DRG 602 (Cellulitis with MCC, relative weight 1.4273) and DRG 603 (Cellulitis without MCC, relative weight 0.8635), in MDC 09 (Diseases and Disorders of the Skin, Subcutaneous Tissue and Breast), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
