About coding nodular fasciitis
The ICD-10-CM code for nodular fasciitis is M72.4 (Pseudosarcomatous fibromatosis).
Within M72 (fibroblastic disorders), M72.4 is specifically for Pseudosarcomatous fibromatosis. Related codes cover palmar fascial fibromatosis [Dupuytren] (M72.0), Knuckle pads (M72.1), plantar fascial fibromatosis (M72.2), necrotizing fasciitis (M72.6), other fibroblastic disorders (M72.8) and fibroblastic disorder, unspecified (M72.9).
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 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.
