Cardiology Coding Guide for 2025

All healthcare professionals, including cardiologists, administrators, and coding specialists, should be aware of the 2025 cardiology updates.

Here are some of the changes for 2025 in Cardiology:

  1. New ICD-11 Codes for 2025
  2. New Category III CPT codes
  3. HCPCS Level II codes
  4. Key Changes in Cardiovascular Coding for 2025

1. ICD 11 Codes

ICD Code Condition
XA0F62
Left main coronary artery
BD10
Congestive heart failure
BA41

XS8U
Multiple vessel disease

2. New Category III CPT codes

In 2025, there haven’t been any new Category I CPT Codes introduced. However, there has been a release of several new CPT III Codes, which focus on the latest developments in advanced cardiac care and remote monitoring technologies.

CPT Range
0897T
Noninvasive Augmentative Arrhythmia Analysis Procedure
0899T
Absolute Quantitation Of Myocardial Blood Flow (Aqmbf) Determination Procedure
0902T
Algorithmic Analysis Derived QTc Interval Using Mobile ECG Device
0903T-0905T
Algorithmically Generated 12-Lead ECG Procedures
0913T-0914T
Transcatheter Therapeutic Drug Delivery by Intracoronary Drug-Delivery Balloon Procedure
0915T-0931T
Cardiac Contractility Modulation-Defibrillation System Procedures
0932T-0934T
Augmentative Analysis of ECG to Detect Heart Failure
0937T-0940T
Continuous External Electrocardiographic Recording Procedures

3. HCPCS Level II codes

For 2025, CMS has introduced new set of codes that are relevant to cardiovascular care.

HCPCS Level II codes Description
G0446
Annual, Face-to-Face Intensive Behavioral Therapy for Cardiovascular Disease
G0537-G0538
Administration of a Standardized, Evidence-Based ASCVD Risk Assessment
G0559
Post-Operative Follow-Up Visit Complexity

4. Key Changes in Cardiovascular Coding for 2025

The coding for coronary artery disease has been updated to better reflect the growing use of non-invasive tests, such as coronary CT angiography. New codes have been introduced to help document the findings from these advanced imaging techniques more accurately.

Hypertension Codes

  • I10: Essential (primary) hypertension
  • I15: Secondary hypertension
  • I16: Hypertensive crisis
  • I11: Hypertensive heart disease

Coronary Artery Disease (CAD)

  • I25.10: Atherosclerotic heart disease of native coronary artery without angina pectoris
  • I25.110: Atherosclerotic heart disease of native coronary artery with unstable angina pectoris
  • I25.2: Old myocardial infarction
  • I25.5: Ischemic cardiomyopathy
  • I25.6: Silent myocardial ischemia
  • I25.700: Atherosclerosis of coronary artery bypass graft without angina pectoris
  • I25.710: Atherosclerosis of coronary artery bypass graft with unstable angina
  • I25.810: Atherosclerosis of coronary artery bypass graft with angina pectoris

Heart Failure Staging

  • I50.9: Heart failure, unspecified
  • I50.1: Left ventricular failure
  • I50.2: Systolic (congestive) heart failure
  • I50.3: Diastolic (congestive) heart failure
  • I50.4: Combined systolic and diastolic heart failure

Atrial Fibrillation (AF) and Arrhythmia

  • I48.0: Paroxysmal atrial fibrillation
  • I48.1: Persistent atrial fibrillation
  • I48.2: Chronic atrial fibrillation
  • I48.3: Typical atrial flutter
  • I48.4: Atypical atrial flutter
