About coding Polyalgia
The ICD-10-CM code for Polyalgia is M79.89 (Other specified soft tissue disorders).
Within M79.8, choose M79.89 (Other specified soft tissue disorders) only when documentation doesn't support a more specific option: nontraumatic hematoma of soft tissue (M79.81).
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.
