CPT 74445: Imaging Supervision and Interpretation of Corpora Cavernosa

CPT code 74445 covers the professional component for imaging supervision and interpretation of the corpora cavernosa performed to evaluate venogenic impotence and to diagnose organic erectile dysfunction from structural abnormalities. Nationally, this code is relevant for encounters where imaging is used to assess penile vascular or structural causes of erectile dysfunction, and it distinguishes the imaging interpretation from technical or procedural components. Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will learn the clinical scope and typical sites of service for CPT code 74445, common billing and documentation considerations tied to the professional component, and which payers commonly reimburse for diagnostic imaging interpretation in this clinical context. The publication summarizes benchmarks and policy context where available and identifies areas labeled as "Data not available in the input" when payer-specific coverage details or associated taxonomies and ICD-10 diagnoses are not provided.

Billing Code Overview

CPT code 74445 describes the imaging supervision and interpretation of the corpora cavernosa to evaluate venogenic impotence and to establish a diagnosis of organic erectile dysfunction due to structural abnormalities of the corpora cavernosa. The service is limited to the professional component of imaging interpretation and supervision only.

Service type: Diagnostic imaging supervision and interpretation
Typical site of service: Outpatient imaging suite or hospital outpatient department, including specialized vascular or urology imaging settings

Clinical & Coding Specifications

Clinical Context

A 45-year-old male presents to a urology clinic with persistent erectile dysfunction following blunt perineal trauma sustained in a motor vehicle collision six months earlier. Prior conservative therapies including phosphodiesterase inhibitors and vacuum devices produced inadequate response. The urologist orders diagnostic vascular imaging to evaluate for venogenic impotence and structural abnormalities of the corpora cavernosa. In the outpatient clinic, the patient undergoes an intracavernosal injection of a vasoactive agent to induce erection under monitored conditions. A radiology or urology imaging team performs cavernosography with fluoroscopic imaging of the corpora cavernosa. The ordering provider documents the clinical indication (post-traumatic erectile dysfunction) and consents the patient for imaging. A physician or qualified non-physician practitioner supervises the imaging acquisition, interprets the images, and issues a written report that documents venous leakage or structural defects of the cavernosal tissue. Billing for the imaging supervision and interpretation component is reported with 74445, representing only the supervision and interpretation portion of cavernosography of the corpora cavernosa.

Coding Specifications

Modifier	Description	When to Use
`26`	Professional component	Use when reporting only the physician interpretation component separate from technical acquisition (applicable to `74445` when imaging performed by another entity).
`TC`	Technical component	Use when reporting only the technical component of imaging (not used with `74445` if only interpretation/supervision is reported).
`52`	Reduced services	Use when the full service was not performed or was partially reduced from the typical protocol.
`53`	Discontinued procedure	Use when the procedure was started but halted due to extenuating circumstances.
`76`	Repeat procedure by same physician	Use when the same physician repeats the procedure later the same day. (Note: `76` is not in the provided modifier list; select clinically relevant available alternatives.)
`78`	Return to OR for related procedure by same physician	Use if an immediate return to a procedure suite is required for a related complication.
`80`	Assistant surgeon	Use when an assistant surgeon legitimately assists during an invasive procedure component of cavernosography.
`62`	Two surgeons	Use when two surgeons work together as primary surgeons for a complex operative portion.
`22`	Increased procedural services	Use when work or complexity substantially exceeds the usual requirements.
`23`	Unusual anesthesia	Use when general anesthesia was medically necessary for an otherwise non‑anesthetized procedure.
`52`	Reduced services	Use when imaging acquisition was curtailed or limited compared with the usual study.

Taxonomy Code	Specialty	Notes
`207V00000X`	Urology	Urologists frequently order, supervise, and interpret cavernosography for erectile dysfunction evaluation.
`207K00000X`	Physician — Radiology	Interventional and diagnostic radiologists perform and interpret cavernosography and fluoroscopic studies.
`163W00000X`	Physician Assistant	PAs assist in procedure setup, injection administration, and may perform imaging under supervision.
`363L00000X`	Registered Nurse First Assistant	Nurses assist with intra‑procedure monitoring and technical support during vascular imaging.
`334S00000X`	Vascular Surgery	Vascular surgeons may be involved when venous pathology requires surgical correlation or intervention.
