Frequently Asked Questions

What is MS-DRG 584?

MS-DRG 584 (Breast Biopsy, Local Excision and Other Breast Procedures with CC/MCC) is a surgical DRG in MDC 09 (Diseases & Disorders of the Skin, Subcutaneous Tissue & Breast). Its FY 2026 relative weight is 2.1407 with a geometric mean length of stay of 3.3 days.

How many procedure codes group to DRG 584?

338 ICD-10-PCS operating-room procedure codes group to this DRG.

What is the relative weight of DRG 584?
