About coding Circinatus herpes
The ICD-10-CM code for Circinatus herpes is B35.4 (Tinea corporis). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on B35.4.
Within B35 (dermatophytosis), B35.4 is specifically for tinea corporis. Related codes cover tinea barbae and tinea capitis (B35.0), tinea unguium (B35.1), tinea manuum (B35.2), tinea pedis (B35.3), tinea imbricata (B35.5), tinea cruris (B35.6), other dermatophytoses (B35.8) and unspecified (B35.9).
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.
