MS-DRG 153 – Otitis Media and URI without MCC
A Medical DRG in MDC 03 (Diseases & Disorders of the Ear, Nose, Mouth & Throat). Inpatient cases group to DRG 153 when the ICD-10-CM principal diagnosis is one of the 220 codes listed below and no secondary diagnosis on the MCC list is present. Its FY 2026 relative weight is 0.7382 with a geometric mean length of stay of 2.2 days.

How a case is assigned to DRG 153
The grouper first assigns the case to MDC 03 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 → 152; without MCC → 153.

Frequently Asked Questions
What is MS-DRG 153?
MS-DRG 153 (Otitis Media and URI without MCC) is a medical DRG in MDC 03 (Diseases & Disorders of the Ear, Nose, Mouth & Throat). Its FY 2026 relative weight is 0.7382 with a geometric mean length of stay of 2.2 days.
What is the difference between DRG 152, 153?
All 2 share the same base category; the severity of secondary diagnoses separates them: 152 (with MCC), 153 (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 153?
220 ICD-10-CM principal diagnosis codes group to this DRG, spanning 28 three-character categories.
What is the relative weight of DRG 153?
The FY 2026 relative weight of this DRG is 0.7382, meaning reimbursement of roughly 0.74 times the average Medicare inpatient case. Multiply by a hospital's blended base rate for the approximate payment.
