About coding Beigel morbus
The ICD-10-CM code for Beigel morbus is B36.2 (White piedra).
Within B36 (other superficial mycoses), B36.2 is specifically for white piedra. Related codes cover pityriasis versicolor (B36.0), tinea nigra (B36.1), black piedra (B36.3), other specified superficial mycoses (B36.8) and superficial mycosis, unspecified (B36.9).
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 606 (Minor Skin Disorders with MCC, relative weight 1.5728) and DRG 607 (Minor Skin Disorders without MCC, relative weight 0.8772), 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.
