About coding Gianotti-Crosti disease
The ICD-10-CM code for Gianotti-Crosti disease is L44.4 (Infantile papular acrodermatitis [Gianotti-Crosti]).
Within L44 (other papulosquamous disorders), L44.4 is specifically for infantile papular acrodermatitis [Gianotti-Crosti]. Related codes cover pityriasis rubra pilaris (L44.0), lichen nitidus (L44.1), lichen striatus (L44.2), lichen ruber moniliformis (L44.3), other specified papulosquamous disorders (L44.8) and papulosquamous disorder, unspecified (L44.9).
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 865 (Viral Illness with MCC, relative weight 1.3485) and DRG 866 (Viral Illness without MCC, relative weight 0.8692), in MDC 18 (Infectious and Parasitic Diseases, Systemic or Unspecified Sites), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
