About M62.3

M62.3 is the ICD-10-CM diagnosis code for Immobility syndrome (paraplegic). 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 (other disorders of muscle), M62.3 is specifically for Immobility syndrome (paraplegic). Related codes cover separation of muscle (nontraumatic) (M62.0), other rupture of muscle (nontraumatic) (M62.1), nontraumatic ischemic infarction of muscle (M62.2), contracture of muscle (M62.4), muscle wasting and atrophy, not elsewhere classified (M62.5), other specified disorders of muscle (M62.8) and disorder of muscle, unspecified (M62.9).

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 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 728.3 (other specific muscle disorders).
