About coding sebaceous glands disease
The ICD-10-CM code for sebaceous glands disease is L73.9 (Follicular disorder, unspecified).
Within L73, choose L73.9 (Follicular disorder, unspecified) only when documentation doesn't support a more specific option: acne keloid (L73.0), Pseudofolliculitis barbae (L73.1), Hidradenitis suppurativa (L73.2) and other specified follicular disorders (L73.8).
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.
