About coding Phagedenic pyoderma
The ICD-10-CM code for Phagedenic pyoderma is L88 (Pyoderma gangrenosum).
Don't report L88 together with the conditions in its Excludes1 note: dermatitis gangrenosa (L08.0).
As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.
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.
Don't confuse with (Excludes1 for L88)
- dermatitis gangrenosa (L08.0)
