027R0ZT PCS Table

In an PCS table each code is represented by up seven alphanumeric characters, with each character in the table respresenting different aspects of the procedure. In the table provided below, each row represents an individual character and includes information about the character's position, designation, label, and procedure notes. For this PCS table the procedure code is in the medical and surgical section and is part of the heart and great vessels body system, classified under dilation operation. The applicable bodypart for this procedure code is pulmonary artery, left.

Clinical Classification

• Clinical Category is Embolectomy, endarterectomy, and related vessel procedures (non-endovascular; excluding carotid)

• CCSR Category Code: CAR007
• Clinical Domain is Cardiovascular Procedures - CAR contains 29 categories that include cardiovascular procedures such as percutaneous coronary intervention (PCI), coronary artery bypass graft (CABG), and aneurysm repair procedures.

027R0ZT is grouped with Diagnostic Related Groups - MS-DRG Mapping

Diagnostic Related Groups (DRGs) are a classification system used to group together procedures for the purpose of reimbursement and healthcare management. DRGs are used to standardize the way hospitals and other providers are paid for inpatient services. In this system patients are grouped together based on the primary procedure being performed. Once a patient is assigned a particular group, providers receive a predetermined payment rate for the services rendered. This reimbursement rate is often fixed and is meant to cover the cost of care associated with a particular procedure. Reimbursement is also affected by the relative weight of a diagnostic related group based on the severity of a patient's illness and the associated cost of care during hospitalization.

Diagnostic related groups encourage healthcare providers to focus on quality and efficiency in patient care while managing costs effectively. The procedure code 027R0ZT is present in the following groups for version MS-DRG V42.0 applicable from 10/01/2024 through 09/30/2025.

Convert to ICD-9-PCS

The following crosswalk between ICD-10-PCS to ICD-9-PCS is based based on the General Equivalence Mappings (GEMS) information:

• ICD-9-PCS: 3749 (Approximate Flag) Approximate Flag
  The approximate flag is on, indicating that the relationship between the code in the source system and the code in the target system is an approximate equivalent.

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 2025 ICD-10-PCS codes are to be used for discharges occurring from October 1, 2024 through September 30, 2025.

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.
