G72.2Myopathy due to other toxic agents

G72.2 is the ICD-10-CM diagnosis code for myopathy due to other toxic agents. It belongs to category G72 (other and unspecified myopathies), block G70-G73 (diseases of myoneural junction and muscle) and chapter 6 (diseases of the nervous system). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within G72, choose G72.2 (Myopathy due to other toxic agents) only when documentation doesn't support a more specific option: drug-induced myopathy (G72.0), alcoholic myopathy (G72.1), periodic paralysis (G72.3), inflammatory and immune myopathies, not elsewhere classified (G72.4), other specified myopathies (G72.8) and myopathy, unspecified (G72.9).

Code first: (T51-T65) to identify toxic agent.

As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.

In MS-DRG v44.0, it is part of the grouping logic for DRG 091 (Other Disorders of Nervous System with MCC, relative weight 1.7046), DRG 092 (Other Disorders of Nervous System with CC, relative weight 1.0239) and DRG 093 (Other Disorders of Nervous System without CC/MCC, relative weight 0.7783), in MDC 01 (Diseases and Disorders of the Nervous System), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 359.4 (toxic myopathy).
