Fibroblastic disorders (M72) ICD-10-CM
The M72 code range covers fibroblastic disorders with 8 ICD-10-CM diagnosis codes. 7 of them are billable and valid for claim submission in fiscal year 2026, 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.

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.
Fasciitis, Plantar
Inflammation of the plantar fascia (APONEUROSIS) on the bottom of the foot causing heel pain. The etiology of plantar fasciitis remains controversial but is likely to involve a biomechanical imbalance. Though often presenting along with HEEL SPUR, they do not appear to be causally related.
Hyaline Fibromatosis Syndrome
Autosomal recessive disorder characterized by HYALINE deposition in the skin, bone, gastrointestinal tract, muscles and glands; multiple subcutaneous skin nodules; GINGIVAL HYPERTROPHY; and joint CONTRACTURES. Mutations in the capillary morphogenesis protein-2 are associated with the disorder.
Leiomyoma
A benign tumor derived from smooth muscle tissue, also known as a fibroid tumor. They rarely occur outside of the UTERUS and the GASTROINTESTINAL TRACT but can occur in the SKIN and SUBCUTANEOUS TISSUE, probably arising from the smooth muscle of small blood vessels in these tissues.
Myofibromatosis
A condition characterized by multiple formations of myofibromas (LEIOMYOMA).
About the M72 Code Range
Fibroblastic disorders (ICD-10 code M72) represent a group of conditions characterized by abnormal growth or thickening of fibrous tissue, commonly affecting palms, feet, skin, or fascia. These codes specify distinct fibroblastic conditions like Dupuytren contracture, plantar fibromatosis, and necrotizing fasciitis.
The ICD-10 code M72 covers various fibroblastic disorders used to classify diseases involving fibrous tissue proliferation. For example, M72.0 codes Palmar fascial fibromatosis, also known as Dupuytren contracture, which causes finger stiffness due to palmar fascia thickening. M72.2 indicates Plantar fascial fibromatosis, often linked to chronic heel pain sometimes referred to as plantar fasciitis. M72.6, Necrotizing fasciitis, codes for a severe, rapidly spreading infection of the fascia frequently caused by Streptococcus bacteria. Other codes like M72.1 and M72.8 cover knuckle pads and other less common fibroblastic conditions. This grouping guides medical coders in selecting precise ICD-10 codes for specialized connective tissue diseases involving fibroblastic growths, ensuring accurate diagnosis documentation.
