M02.159Postdysenteric arthropathy, unspecified hip

M02.159 is the ICD-10-CM diagnosis code for Postdysenteric arthropathy, unspecified hip. It belongs to category M02 (postinfective and reactive arthropathies), block M00-M02 (infectious arthropathies) 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 M02.15, choose M02.159 (unspecified hip) only when documentation doesn't support a more specific option: right hip (M02.151) and left hip (M02.152).

Code first underlying disease, such as: congenital syphilis [Clutton's joints] (A50.5), enteritis due to Yersinia enterocolitica (A04.6), infective endocarditis (I33.0) and viral hepatitis (B15-B19).

As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.

In MS-DRG v44.0, it is part of the grouping logic for DRG 553 (Bone Diseases and Arthropathies with MCC, relative weight 1.2494) and DRG 554 (Bone Diseases and Arthropathies without MCC, relative weight 0.8331), 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 is an unspecified code for which a more specific option (often laterality) exists, and the Medicare Code Editor flags it for review on inpatient claims.

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 711.35 (Postdysenteric arthropathy, pelvic region and thigh).
