Imaging Guided Procedure Naming

This Editorial Guide is used for Education Purposes Only. It is used in the Authoring Courses and Certifications. It is based on the January 2026 Editorial Guide.

There are numerous procedures where the imaging component is considered a supplemental or secondary technique to help accomplish the primary goal. The pattern is:

Procedure using guidance

• FSN: Y using guidance (procedure)

• PT: guided Y

• SYN: Y using guidance

Computed tomography guided procedure

• FSN: Y using computed tomography guidance (procedure)

• PT: CT guided Y

• SYN: Y using computed tomography guidance

  • For example,

    • 431864000 | Injection using computed tomography guidance (procedure)|

      • FSN: Injection using computed tomography guidance (procedure)

      • PT: CT guided injection

      • SYN: Injection using computed tomography guidance

Fluoroscopy guided procedure

• FSN: Y using fluoroscopic guidance (procedure)

• PT: Fluoroscopy guided Y

• SYN: Y using fluoroscopic guidance

  • For example,

    • 773291002 | Biopsy of abdomen using fluoroscopic guidance (procedure)|

      • FSN: Biopsy of abdomen using fluoroscopic guidance (procedure)

      • PT: Fluoroscopy guided biopsy of abdomen

      • SYN: Biopsy of abdomen using fluoroscopic guidance

Fluoroscopic guidance

The term fluoroscopic Y is interpreted as Y using fluoroscopic guidance (procedure). Procedures such as 432540009 | Biopsy of wrist using fluoroscopic guidance (procedure)| are subtypes of Fluoroscopy (procedure).

Magnetic resonance imaging guided procedure

• FSN: Y using magnetic resonance imaging guidance (procedure)

• PT: MRI guided Y

• SYN: Y using magnetic resonance imaging guidance

  • For example,

    • 433008009 | Core needle biopsy of breast using magnetic resonance imaging guidance (procedure)|

      • FSN: Core needle biopsy of breast using magnetic resonance imaging guidance (procedure)

      • PT: MRI guided core needle biopsy of breast

      • SYN: Core needle biopsy of breast using magnetic resonance imaging guidance

Ultrasonography guided procedure

• FSN: Y using ultrasonographic guidance (procedure)

• PT: Ultrasonography guided Y

• SYN: Y using ultrasonographic guidance

• SYN: Y using ultrasound guidance

  • For example,

    • 431811004 | Biopsy of wrist using ultrasonographic guidance (procedure)|

      • FSN: Biopsy of wrist using ultrasonographic guidance (procedure)

      • PT: Ultrasonography guided biopsy of wrist

      • SYN: Biopsy of wrist using ultrasonographic guidance

      • SYN: Biopsy of wrist using ultrasound guidance

Plain X-ray guided procedure

• FSN: Y using plain X-ray guidance (procedure)

• PT: Plain X-ray guided Y

• SYN: Y using plain X-ray guidance

  • For example,

    • 718674009 | Injection of steroid using X-ray guidance (procedure)|

      • FSN: Injection of steroid using plain X-ray guidance (procedure)

      • PT: Plain X-ray guided steroid injection

      • SYN: Injection of steroid using plain X-ray guidance
