ICD-10 code for tag
From the official ICD-10-CM alphabetic index entry “Tag (hypertrophied skin) (infected)”. Page updated September 29, 2026.
About coding tag
The ICD-10-CM code for tag is L91.8 (Other hypertrophic disorders of the skin). The official index lists 15 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on L91.8.
Within L91, choose L91.8 (Other hypertrophic disorders of the skin) only when documentation doesn't support a more specific option: hypertrophic scar (L91.0) and hypertrophic disorder of the skin, unspecified (L91.9).
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.
