About coding hypertrichosis
The ICD-10-CM code for hypertrichosis is L68.9 (Hypertrichosis, unspecified). The official index lists 12 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on L68.9.
Within L68, choose L68.9 (unspecified) only when documentation doesn't support a more specific option: Hirsutism (L68.0), acquired hypertrichosis lanuginosa (L68.1), localized hypertrichosis (L68.2), Polytrichia (L68.3) and other hypertrichosis (L68.8).
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.
