About coding wart
The ICD-10-CM code for wart is B07.9 (Viral wart, unspecified). The official index lists 14 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on B07.9.
Within B07, choose B07.9 (Viral wart, unspecified) only when documentation doesn't support a more specific option: plantar wart (B07.0) and other viral warts (B07.8).
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.
