These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
The “use additional code” indicates that a secondary code could be used to further specify the patient’s condition. This note is not mandatory and is only used if enough information is available to assign an additional code.
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Clinical ClassificationClinical
AHRQ’s CCSR groups this code into broader clinical categories.
Clinical InformationClinical
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.Myofibromatosis
a condition characterized by multiple formations of myofibromas (leiomyoma).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.Superficial Fibromatosis
a poorly circumscribed, intermediate fibrocytic neoplasm arising from the superficial soft tissues. it is characterized by the presence of spindle-shaped fibroblasts, and an infiltrative growth pattern.Proliferative Fasciitis
a rapidly growing, poorly circumscribed, mass-forming proliferation that arises from the subcutaneous tissues. it is characterized by the presence of spindle-shaped fibroblasts, round ganglion-like cells, myxoid to collagenous stroma formation, and high mitotic activity. it recurs only rarely following local excision and does not metastasize.
Patient EducationClinical
Connective Tissue Disorders
Your connective tissue supports many different parts of your body, such as your skin, eyes, and heart. It is like a "cellular glue" that gives your body parts their shape and helps keep them strong. It also helps some of your tissues do their work. It is made of many kinds of proteins. Cartilage and fat are types of connective tissue.

Yes. This is a billable ICD-10-CM code, specific enough to report other fibroblastic disorders on HIPAA-covered claims from October 1, 2025 through September 30, 2026.
What MS-DRG does M72.8 group to?
When other fibroblastic disorders is the principal diagnosis on an inpatient stay, it groups to MS-DRG 557, 558, with relative weights from 0.8932 to 1.4869 depending on complications. Higher weights mean higher Medicare reimbursement.
What is the ICD-9 equivalent of M72.8?
Under the General Equivalence Mappings, other fibroblastic disorders converts to ICD-9-CM 728.89 (muscle/ligament dis NEC). The mapping is approximate, so confirm the match fits the documentation.
Footnotes
[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
