About coding fibromatosis
The ICD-10-CM code for fibromatosis is M72.9 (Fibroblastic disorder, unspecified). The official index lists 8 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on M72.9.
Within M72, choose M72.9 (Fibroblastic disorder, unspecified) only when documentation doesn't support a more specific option: palmar fascial fibromatosis [Dupuytren] (M72.0), Knuckle pads (M72.1), plantar fascial fibromatosis (M72.2), Pseudosarcomatous fibromatosis (M72.4), necrotizing fasciitis (M72.6) and other fibroblastic disorders (M72.8).
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 557 (Tendonitis, Myositis and Bursitis with MCC, relative weight 1.489) and DRG 558 (Tendonitis, Myositis and Bursitis without MCC, relative weight 0.8875), in MDC 08 (Diseases and Disorders of the Musculoskeletal System and Connective Tissue), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
