About coding Grayness
The ICD-10-CM code for Grayness is L67.1 (Variations in hair color). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on L67.1.
Within L67 (hair color and hair shaft abnormalities), L67.1 is specifically for Variations in hair color. Related codes cover Trichorrhexis nodosa (L67.0), other hair color and hair shaft abnormalities (L67.8) and hair color and hair shaft abnormality, unspecified (L67.9).
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.
