About M00.032
M00.032 is the ICD-10-CM diagnosis code for staphylococcal arthritis, left wrist. It belongs to category M00 (pyogenic arthritis), 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 M00.03 (staphylococcal arthritis, wrist), M00.032 is specifically for staphylococcal arthritis, left wrist. Related codes cover right wrist (M00.031) and unspecified wrist (M00.039).
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 548 (Septic Arthritis with MCC, relative weight 1.9519), DRG 549 (Septic Arthritis with CC, relative weight 1.1435) and DRG 550 (Septic Arthritis without CC/MCC, relative weight 0.8591), 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 041.10 (staphylococcus infection in conditions classified elsewhere and of unspecified site, staphylococcus, unspecified) and 711.03 (pyogenic arthritis, forearm).
