MS-DRG Lookup: Search 772 FY 2026 Medicare DRGs
Find the MS-DRG codes an ICD-10-CM diagnosis code, an ICD-10-PCS procedure code, or a clinical term groups to under grouper version v43.0. Every result links to the full DRG page with relative weight, mean length of stay, severity family, and the complete code lists. Already know the DRG number? Type it to go straight to its page.
How to Find a DRG Code
Enter a diagnosis or procedure code
Type a complete ICD-10-CM code like S72.001A or an ICD-10-PCS code like 0SR9019, with or without the dot. The results list every MS-DRG that code can group to, including each severity level of the family.
Search a condition or procedure name
Search terms like sepsis, hip replacement, or craniotomy. Matching works across the official code descriptions on both code sets; use the toggle to limit results to diagnoses or procedures only.
Go straight to a DRG page
If you already have the DRG number, enter it (470 or 023) to open that DRG’s page directly, with its relative weight, mean length of stay, severity family, and complete FY 2026 code lists.
Frequently Asked Questions
How do I find which DRG a diagnosis or procedure code maps to?
Enter the ICD-10-CM or ICD-10-PCS code in the search box. The results show every MS-DRG the code is listed under in the CMS FY 2026 Definitions Manual, with each DRG’s relative weight and mean length of stay. Select a result to open the full DRG page.
Is this lookup the same as a DRG grouper?
No. A grouper assigns the single billing DRG for a complete claim using the principal diagnosis, all secondary diagnoses (CC/MCC), procedures, and discharge status together. This lookup answers the question a step earlier: which MS-DRGs a given code can group to. Each DRG page then explains the assignment rule and the severity levels of its family.
Why does one code return several DRGs?
Most MS-DRGs come in severity families, such as 469 and 470 for major joint replacement. The same diagnosis or procedure code appears in each sibling, and the claim’s secondary diagnoses decide whether the with-MCC, with-CC, or without-CC/MCC level applies. Results show every sibling with its family marked.
Does the lookup cover both diagnosis and procedure codes?
Yes. It searches the diagnosis side (Medical DRGs) and the procedure side (Surgical DRGs) of the FY 2026 MS-DRG v43.0 dataset in one search: 666,399 code-to-DRG mappings, with each result labeled Medical or Surgical.
