M62.84Sarcopenia

M62.84 is the ICD-10-CM diagnosis code for Sarcopenia. 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), M62.84 is specifically for Sarcopenia. Related codes cover muscle weakness (generalized) (M62.81), Rhabdomyolysis (M62.82), muscle spasm (M62.83), dysfunction of the multifidus muscles, lumbar region (M62.85) and other specified disorders of muscle (M62.89).

Code first underlying disease, if applicable, such as: disorders of myoneural junction and muscle disease in diseases classified elsewhere (G73.-), other and unspecified myopathies (G72.-) and primary disorders of muscles (G71.-).

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

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 was added in FY2017, effective October 1, 2016.

Before ICD-10, this condition was coded in ICD-9-CM as 728.3 (other specific muscle disorders).
