MS-DRG 948 – Signs and Symptoms without MCC

A Medical DRG in MDC 23 (Factors Influencing Health Status & Other Contacts with Health Services). Inpatient cases group to DRG 948 when the ICD-10-CM principal diagnosis is one of the 130 codes listed below and no secondary diagnosis on the MCC list is present. Its FY 2026 relative weight is 0.8005 with a geometric mean length of stay of 2.6 days.

How a case is assigned to DRG 948

The grouper first assigns the case to MDC 23 from the principal diagnosis and finds no qualifying operating-room procedure (this is a Medical DRG; ICD-10-PCS codes do not drive assignment here), then applies the severity split from secondary diagnoses: with MCC → 947; without MCC → 948.

Frequently Asked Questions

What is MS-DRG 948?

MS-DRG 948 (Signs and Symptoms without MCC) is a medical DRG in MDC 23 (Factors Influencing Health Status & Other Contacts with Health Services). Its FY 2026 relative weight is 0.8005 with a geometric mean length of stay of 2.6 days.

What is the difference between DRG 947, 948?

All 2 share the same base category; the severity of secondary diagnoses separates them: 947 (with MCC), 948 (without MCC). A major complication or comorbidity (MCC) places the case in the highest-weighted DRG of the family; a CC in the middle; neither in the lowest.

How many diagnosis codes group to DRG 948?

130 ICD-10-CM principal diagnosis codes group to this DRG, spanning 29 three-character categories.

What is the relative weight of DRG 948?

The FY 2026 relative weight of this DRG is 0.8005, meaning reimbursement of roughly 0.80 times the average Medicare inpatient case. Multiply by a hospital's blended base rate for the approximate payment.
