About M07.641

M07.641 is the ICD-10-CM diagnosis code for Enteropathic arthropathies, right hand. It belongs to category M07 (Enteropathic arthropathies), 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 M07.64 (Enteropathic arthropathies, hand), M07.641 is specifically for Enteropathic arthropathies, right hand. Related codes cover left hand (M07.642) and unspecified hand (M07.649).

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 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 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 713.1 (arthropathy associated with gastrointestinal conditions other than infections) and 716.84 (other specified arthropathy, hand).
