About coding Trichonodosis
The ICD-10-CM code for Trichonodosis is L67.8 (Other hair color and hair shaft abnormalities).
Within L67, choose L67.8 (Other hair color and hair shaft abnormalities) only when documentation doesn't support a more specific option: Trichorrhexis nodosa (L67.0), Variations in hair color (L67.1) 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.
