FY 2027 ICD-10-PCS Update Overview: Key Numbers at a Glance
The Centers for Medicare & Medicaid Services (CMS) recently published the FY 2027 ICD-10-PCS code set, bringing a fresh round of additions, deletions, and structural updates to the inpatient procedure coding system.
Here is a quick snapshot of what changed:
| Update Type | Count |
|---|---|
| New Codes Added | 101 |
| Codes Deleted | 38 |
| New Tables Added | 1 |
| Total FY 2027 ICD-10-PCS Codes | 79,256 |
These updates apply to all inpatient discharges occurring from October 1, 2026 through September 30, 2027. While CMS made no significant changes to the Official Guidelines for Coding and Reporting themselves, the expanded code set reflects meaningful advances in surgical techniques, medical devices, and emerging technologies entering mainstream clinical practice.
What Did CMS Change in the FY 2027 ICD-10-PCS Guidelines?
Good news for coders who were bracing for a major overhaul — CMS made no significant changes to the ICD-10-PCS Official Guidelines for Coding and Reporting for FY 2027. The core coding conventions, general guidelines, and procedure-specific guidance remain consistent with the prior year.
That said, the 101 new procedure codes and one new table mean you will need to update your encoder, coding references, and internal tools before the October 1, 2026 effective date.
New ICD-10-PCS Codes for FY 2027: Tabular Updates by Procedure Category
The new codes span a wide range of clinical procedures. Below is a breakdown of the most notable tabular updates medical coders should be aware of.
Cardiac and Vascular Procedures
- Table 028 — Division of Heart Valves: New body part characters have been added for the division of the aortic valve and mitral valve, along with two new qualifier characters distinguishing between a native leaflet and a prosthetic leaflet. This is a clinically significant distinction that directly affects accurate code assignment for valve procedures.
- Table 5A0 — Assistance with Circulatory Function: A new function and qualifier value now captures continuous assistance with circulatory decompression using an impeller pump — an important addition for coders documenting procedures involving mechanical circulatory support devices.
Spinal Fusion Procedures with Custom-Made Devices
Two new device values address the growing use of anatomically and virtually designed custom-made interbody fusion devices in spinal surgery:
- Table 0RG — Fusion of Thoracolumbar Vertebral Joint using a custom-made interbody fusion device
- Table 0SG — Fusion of Lumbar Vertebral Joints and Lumbosacral Joint using a custom-made interbody fusion device
These additions reflect the increasing adoption of patient-specific implant technology in orthopedic and neurosurgical spine procedures.
Drainage and Fluid Management Procedures
- Table 0W9 — Drainage of Pleural Cavity and Mediastinum: A new qualifier value has been added for drainage procedures using an active mechanical clearance drainage device, providing more specificity for coders documenting chest and mediastinal drainage.
Transfusion and Infusion Procedures
- Table 302 — Transfusion: A new qualifier value captures transfusion of high-dose immune globulin into both peripheral and central veins — an important update for coders working in oncology, immunology, and critical care settings.
Introduction and Administration Procedures
- Table 3E0 — Introduction: New qualifier values now cover the introduction of other enzymatic or chemical agents into skin and mucous membranes, as well as subcutaneous tissue — expanding specificity for dermatological and wound care procedures.
Urinary Filtration Procedures
- Table 5A1 — Performance of Urinary Filtration: A new qualifier value documents urinary filtration performed with a selective cytopheretic device, reflecting advances in extracorporeal treatment for acute kidney injury.
Imaging Procedures
- New Table — Other Imaging Procedures Involving the Eye: An entirely new ICD-10-PCS table has been created for other imaging procedures involving the eye, filling a previous gap in the code set for ophthalmic imaging documentation.
New Technology Table Updates: 50 New Codes Across 13 Tables
A significant portion of the FY 2027 additions — 50 of the 101 new codes — fall under 13 new technology (Section X) tables, which capture emerging procedures using innovative technologies that have not yet been fully integrated into the main ICD-10-PCS tables.
One of the most notable additions is an entirely new table for Other Procedures on Physiological Systems and Anatomical Regions, which includes several cutting-edge procedures using new technology group 12.
Notable New Technology Codes for FY 2027
Here are some of the most clinically significant new technology codes medical coders should be familiar with:
XEZD3QC — Pericardial cavity access using a blunt-tip concealed needle with mechanical gripping mechanism, percutaneous approach
Relevant for coders documenting minimally invasive pericardial procedures.
XEZJ3NC — Coronary artery access using an image-guided crossing and re-entry system, percutaneous approach
Important for interventional cardiology procedure coding.
XEZU3HC — Computer-aided guidance for intraprocedural navigation using ultrasound imaging with continuous needle tracking in the spinal canal, percutaneous approach
Key for coders working in spine surgery and pain management settings.
XEZZXJC — High-dimensional mixture-of-experts computer-aided assessment of inflammatory response and organ function, for notification and triage
A landmark code reflecting the integration of artificial intelligence and machine learning tools into clinical decision-making and patient triage.
XEZZXLC — Computer-aided detection and notification for imaging abnormalities in echocardiography
Relevant for cardiac imaging and AI-assisted diagnostic coding.
XEZZXPC — Cardiac conduction mechanism, computer-aided guidance for three-dimensional intraprocedural navigation using fluoroscopic imaging
Important for electrophysiology and cardiac catheterization lab procedure coding.
These new technology codes highlight a clear trend — artificial intelligence, computer-aided guidance systems, and patient-specific medical devices are becoming an increasingly important part of inpatient procedure documentation and coding.
FY 2027 ICD-10-PCS Code Deletions: 38 Codes Removed
Alongside the new additions, 38 codes have been deleted from the FY 2027 ICD-10-PCS code set. All deletions occur within the new technology (Section X) tables, specifically in the following tables:
| Deleted Table | Procedure Category |
|---|---|
| X2K | Bypass of Cardiovascular System |
| XD2 | Monitoring of the Gastrointestinal System |
| XRG | Fusion of Joints |
| XW0 | Introduction into Anatomical Regions |
| XW1 | Transfusion into Anatomical Regions |
| XXE | Measurement of Physiological Systems |
Coders should review any active encounter forms, charge description masters (CDMs), or encoder favorites that reference these deleted codes and update them prior to October 1, 2026 to avoid claim rejections or coding errors.
What FY 2027 ICD-10-PCS Changes Mean for Medical Coders
These updates carry real, practical implications for your day-to-day coding work. Here is what to prioritize before the new fiscal year begins:
1. Update Your Encoder and Code References Ensure your coding software, encoder, and any printed or digital code books are updated to reflect all 101 new codes, 38 deletions, and the new imaging table before October 1, 2026.
2. Review New Technology (Section X) Codes Carefully With 50 new codes in new technology tables alone, coders in cardiac, spinal, urological, and AI-assisted procedure areas will need focused education on when and how to apply these codes correctly.
3. Pay Attention to Custom Device Coding for Spine Procedures The new device values in tables 0RG and 0SG for custom-made interbody fusion devices reflect a growing trend in personalized implant technology. Accurate device coding in spinal fusion cases directly affects MS-DRG assignment and reimbursement.
4. Audit Deleted Codes in Your System Cross-check all six affected new technology tables for deleted codes and update any internal tools, charge capture forms, or coding workflows accordingly.
5. Stay Aligned with CDI Teams Many of these new codes — especially those involving AI-assisted procedures, mechanical circulatory support, and custom implants — require detailed clinical documentation to support correct code assignment. Early alignment with your CDI team ensures the documentation is in place when these procedures are performed.
