MS-DRG Mapping for ICD-10-PCS Code X05233B

ICD-10-PCS procedure codes are grouped into Medicare Severity Diagnosis Related Groups (MS-DRGs) to support consistent hospital reimbursement and care planning. MS-DRGs classify inpatient stays based on clinical similarity and expected resource use, using information such as the primary procedure, secondary diagnoses, and patient condition.

Each hospital stay is assigned a single DRG, which determines a fixed payment rate from Medicare. This rate accounts for the complexity of the procedure and the overall cost of care.

The code X05233B maps to the following MS-DRGs in version V43.0, effective from October 1, 2025, through September 30, 2026. These groupings are key to understanding how the procedure impacts billing and hospital resource allocation.

What is ICD-10-PCS?

The ICD-10 Procedure Coding System (ICD-10-PCS) is a catalog of procedural codes used by medical professionals for hospital inpatient healthcare settings. The Centers for Medicare and Medicaid Services (CMS) maintain the catalog in the U.S. releasing yearly updates. The 2026 ICD-10-PCS codes are to be used for discharges occurring from October 1, 2025 through September 30, 2026.

Each ICD-10-PCS code has a structure of seven alphanumeric characters and contains no decimals. The first character defines the major "section". Depending on the "section" the second through seventh characters mean different things.
