About coding infective fasciitis
The ICD-10-CM code for infective fasciitis is M72.8 (Other fibroblastic disorders). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on M72.8.
Within M72, choose M72.8 (Other fibroblastic disorders) 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 fibroblastic disorder, unspecified (M72.9).
Don't report M72.8 together with the conditions in its Excludes1 note: diffuse (eosinophilic) fasciitis (M35.4), necrotizing fasciitis (M72.6), nodular fasciitis (M72.4), perirenal fasciitis NOS (N13.5) and 2 more.
Use an additional code to (B95.-, B96.-) identify causative organism.
