MS-DRG 684: RENAL FAILURE WITHOUT CC/MCC
MS-DRG 684 is renal failure without cc/mcc, in MDC 11 (a medical DRG), at the without-CC/MCC level. Its FY2027 relative weight is 0.6003, so a case here pays less than the average Medicare inpatient stay (weight 1.0), with a geometric mean length of stay of 2.20 days. 22 ICD-10-CM principal diagnoses group into MS-DRGs 682–684 under the CMS definitions manual; the most-searched are listed below.

This DRG is subject to the post-acute care transfer policy: a discharge to a qualifying setting below the mean length of stay is paid per diem rather than in full.
Principal diagnoses that group to MS-DRGs 682–684
From the CMS MS-DRG definitions manual’s principal-diagnosis index: 22 ICD-10-CM codes route here, and the CC/MCC status of the secondary diagnoses decides which of 682–684 the case lands in. The 22 most-searched:
- I12.9Hypertensive chronic kidney disease with stage 1 through stage 4 chronic kidney disease, or unspecified chronic kidney disease
- N17.9Acute kidney failure, unspecified
- N18.6End stage renal disease
- I12.0Hypertensive chronic kidney disease with stage 5 chronic kidney disease or end stage renal disease
- N18.31Chronic kidney disease, stage 3a
- N18.32Chronic kidney disease, stage 3b
- N18.9Chronic kidney disease, unspecified
- N18.5Chronic kidney disease, stage 5
- I13.10Hypertensive heart and chronic kidney disease without heart failure, with stage 1 through stage 4 chronic kidney disease, or unspecified chronic kidney disease
- N18.30Chronic kidney disease, stage 3 unspecified
- N19Unspecified kidney failure
- N18.2Chronic kidney disease, stage 2 (mild)
- N18.4Chronic kidney disease, stage 4 (severe)
- I13.11Hypertensive heart and chronic kidney disease without heart failure, with stage 5 chronic kidney disease, or end stage renal disease
- N17.0Acute kidney failure with tubular necrosis
- N17.8Other acute kidney failure
- R34Anuria and oliguria
- N18.1Chronic kidney disease, stage 1
- N17.1Acute kidney failure with acute cortical necrosis
