About coding hair abnormal
The ICD-10-CM code for hair abnormal is L67.9 (Hair color and hair shaft abnormality, unspecified). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on L67.9.
Within L67, choose L67.9 (Hair color and hair shaft abnormality, unspecified) only when documentation doesn't support a more specific option: Trichorrhexis nodosa (L67.0), Variations in hair color (L67.1) and other hair color and hair shaft abnormalities (L67.8).
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.
