Heart (B2) ICD-10-PCS
The B2 body system covers Imaging procedures on heart, with 284 ICD-10-PCS codes across 5 root operations, 274 of them billable in fiscal year 2026. Each root operation defines a distinct procedural objective, and the info icons show the official definition with a preview of the codes inside.

| Chars 1–3 | Root Operation | Codes | Billable |
|---|---|---|---|
| B20 | Plain RadiographyPlanar display of an image developed from the capture of external ionizing radiation on photographic or photoconductive plate | 62 | 60 |

About the B2 Body System
The ICD-10-PCS root operation for Heart Imaging (Section B2) refers to various diagnostic techniques used to produce visual representations of the heart’s structure and function. This operation is part of the Imaging section, focusing on non-invasive methods to aid clinical evaluation without altering body tissues.
Within this classification, procedures include Plain Radiography (B20), which captures static images using external ionizing radiation on photographic plates. Fluoroscopy (B21) provides dynamic, real-time images via a fluorescent screen, useful in procedural guidance. Advanced techniques such as Computerized Tomography (CT Scan) (B22) and Magnetic Resonance Imaging (MRI) (B23) offer multiplanar digital images through ionizing radiation and radiofrequency signal capture, respectively. Finally, Ultrasonography (B24) uses high-frequency sound waves to visualize heart anatomy and blood flow in real time. These heart imaging codes allow precise documentation of the diagnostic modality used, supporting accurate clinical assessment and treatment planning.
Questions About This Page
How many codes are in the B2 body system?
The B2 body system contains 284 ICD-10-PCS codes in FY 2026, organized into 5 root operations. 274 of them are billable on inpatient claims.
What is a root operation?
The root operation is the third character of every ICD-10-PCS code and names the objective of the procedure. Drainage takes fluid out, Excision cuts out a portion of a body part, and Resection removes all of one. Picking the right root operation is the central skill of PCS coding, so each one above carries its official CMS definition.
