M62.82Rhabdomyolysis

M62.82 is the ICD-10-CM diagnosis code for Rhabdomyolysis. It belongs to category M62 (other disorders of muscle), block M60-M63 (disorders of muscles) and chapter 13 (diseases of the musculoskeletal system and connective tissue). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within M62.8 (other specified disorders of muscle), M62.82 is specifically for Rhabdomyolysis. Related codes cover muscle weakness (generalized) (M62.81), muscle spasm (M62.83), Sarcopenia (M62.84), dysfunction of the multifidus muscles, lumbar region (M62.85) and other specified disorders of muscle (M62.89).

Don't report M62.82 together with the conditions in its Excludes1 note: traumatic rhabdomyolysis (T79.6).

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 557 (Tendonitis, Myositis and Bursitis with MCC, relative weight 1.489) and DRG 558 (Tendonitis, Myositis and Bursitis without MCC, relative weight 0.8875), in MDC 08 (Diseases and Disorders of the Musculoskeletal System and Connective Tissue), 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 728.88 (Rhabdomyolysis).
