About coding hip pain
The ICD-10-CM code for hip pain is M25.559 (Pain in unspecified hip). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on M25.559.
Within M25.55, choose M25.559 (unspecified hip) only when documentation doesn't support a more specific option: right hip (M25.551) and left hip (M25.552).
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.
