About coding Trichorrhexis
The ICD-10-CM code for Trichorrhexis is L67.0 (Trichorrhexis nodosa).
Within L67 (hair color and hair shaft abnormalities), L67.0 is specifically for Trichorrhexis nodosa. Related codes cover Variations in hair color (L67.1), 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.
