It belongs to category M70 (soft tissue disorders related to use, overuse and pressure), block M70-M79 (other soft tissue 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 M70.03 (Crepitant synovitis (acute) (chronic), wrist), M70.032 is specifically for Crepitant synovitis (acute) (chronic), left wrist. Related codes cover right wrist (M70.031) and unspecified wrist (M70.039).

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

The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
