Fibroblastic disorders (M72) ICD-10-CM
The M72 code range covers fibroblastic disorders with 11 ICD-10-CM diagnosis codes. 9 of them are billable and valid for claim submission in fiscal year 2027, and the category headers group them but cannot themselves be billed.
Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the M72 range.
Fasciitis
Inflammation of the fascia. There are three major types: 1, Eosinophilic fasciitis, an inflammatory reaction with eosinophilia, producing hard thickened skin with an orange-peel configuration suggestive of scleroderma and considered by some a variant of scleroderma; 2, Necrotizing fasciitis (FASCIITIS, NECROTIZING), a serious fulminating infection (usually by a beta hemolytic streptococcus) causing extensive necrosis of superficial fascia; 3, Nodular/Pseudosarcomatous /Proliferative fasciitis, characterized by a rapid growth of fibroblasts with mononuclear inflammatory cells and proliferating capillaries in soft tissue, often the forearm; it is not malignant but is sometimes mistaken for fibrosarcoma.
Fasciitis, Necrotizing
A fulminating bacterial infection of the deep layers of the skin and FASCIA. It can be caused by many different organisms, with STREPTOCOCCUS PYOGENES being the most common.
Knuckle Pads
Benign skin fibromas, typically occurring over the small joints of the hands and feet, that are associated with repetitive friction or pressure.
About the M72 Code Range
These soft tissue disorders include conditions named for the palm, knuckles, and sole of the foot, along with other named forms.
Within M72, M72.0 identifies palmar fascial fibromatosis, M72.1 knuckle pads, and M72.2 plantar fascial fibromatosis. The plantar codes distinguish an unspecified foot (M72.20), right foot (M72.21), and left foot (M72.22). The remaining subdivisions identify pseudosarcomatous fibromatosis (M72.4), necrotizing fasciitis (M72.6), other fibroblastic disorders (M72.8), and an unspecified fibroblastic disorder (M72.9).
FY 2027 changes: The FY 2027 ICD-10-CM update, effective October 1, 2026, added M72.20, M72.21 and M72.22 and deleted M72.2.
