About M08.271
M08.271 is the ICD-10-CM diagnosis code for juvenile rheumatoid arthritis with systemic onset, right ankle and foot. It belongs to category M08 (juvenile arthritis), block M05-M14 (inflammatory polyarthropathies) 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 M08.27 (juvenile rheumatoid arthritis with systemic onset, ankle and foot), M08.271 is specifically for juvenile rheumatoid arthritis with systemic onset, right ankle and foot. Related codes cover left ankle and foot (M08.272) and unspecified ankle and foot (M08.279).
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 545 (Connective Tissue Disorders with MCC, relative weight 2.3892), DRG 546 (Connective Tissue Disorders with CC, relative weight 1.1745) and DRG 547 (Connective Tissue Disorders without CC/MCC, relative weight 0.7526), 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 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 714.30 (Polyarticular juvenile rheumatoid arthritis, chronic or unspecified).
