ICD-10 Code G72.8 – Other specified myopathies (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G72.8 – Other specified myopathies
What it is
G72.8 identifies a muscle disorder that does not fit a more specific myopathy code. Use it when documentation names an atypical or specified myopathy, but a more exact ICD-10 option is not available.
Clinical signs
Clinical features vary; refer to documentation. Commonly, myopathies involve muscle weakness, reduced endurance, or muscle pain, but coding depends on the documented diagnosis rather than symptoms alone.
When to use this code
Use G72.8 when the provider documents a specific myopathy that is not classified elsewhere in ICD-10-CM. It may also apply when the record clearly states “other specified myopathy” or a named muscle disorder without a dedicated code. Check documentation carefully before assigning it.
Do not use for
Do not use this code for unspecified muscle symptoms, generalized weakness without a myopathy diagnosis, or conditions with a more specific ICD-10-CM code. If the chart is unclear, check documentation.
Coding tip
Assign G72.8 only after confirming the provider’s exact myopathy diagnosis and ruling out a more specific code.
