About M25.59

M25.59 is the ICD-10-CM diagnosis code for pain in other specified joint. It belongs to category M25 (other joint disorder, not elsewhere classified), block M20-M25 (other joint disorders) 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 M25.5, choose M25.59 (other specified joint) only when documentation doesn't support a more specific option: unspecified joint (M25.50), shoulder (M25.51), elbow (M25.52), wrist (M25.53), s of hand (M25.54), hip (M25.55), knee (M25.56) and ankle and joints of foot (M25.57).

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 555 (Signs and Symptoms of Musculoskeletal System and Connective Tissue with MCC, relative weight 1.2913) and DRG 556 (Signs and Symptoms of Musculoskeletal System and Connective Tissue without MCC, relative weight 0.8211), 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 FY2021, effective October 1, 2020.
