Summary & Overview
CPT 78761: Nuclear Medicine Testicular Imaging with Radiopharmaceutical Injection
CPT code 78761 represents a nuclear medicine imaging procedure with radiopharmaceutical injection used to evaluate acute testicular or scrotal pain, helping to distinguish causes such as torsion, tumors, cysts, or abscesses. This imaging study is clinically important because rapid and accurate diagnosis can directly influence urgent surgical decisions and patient outcomes. Nationally, the procedure is relevant across hospital outpatient departments and specialized imaging centers where nuclear medicine services are available.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an explanation of the clinical indication and service context for the code, an outline of common billing modifiers and payer considerations where available, and a summary of areas typically addressed in benchmarking and policy reviews (coverage variations, site-of-service implications, and documentation essentials). The publication also highlights coding relationships and common practice patterns tied to nuclear medicine evaluations of acute scrotal pain.
This resource is intended for clinicians, coding professionals, and policy analysts seeking a concise reference on CPT code 78761, its clinical purpose, and the payer landscape commonly associated with this service. Data not available in the input is noted where applicable.
Billing Code Overview
CPT code 78761 describes a nuclear medicine diagnostic procedure that includes injection of a radiopharmaceutical tracer to evaluate acute scrotal or testicular pain. The test is used to identify causes such as testicular torsion, tumor, cyst, or abscess by assessing perfusion and tracer uptake in the testicles.
Service Type: Nuclear medicine diagnostic imaging with radiopharmaceutical injection
Typical Site of Service: Hospital outpatient department, imaging center, or nuclear medicine suite

Clinical & Coding Specifications
Clinical Context
A 28-year-old male presents to the emergency department with sudden onset severe right-sided testicular pain and scrotal swelling for 6 hours. Physical exam shows an exquisitely tender, swollen right testicle with a high-riding position and absent cremasteric reflex, raising concern for acute testicular torsion versus other causes such as tumor, cyst, or abscess. Urgent evaluation includes scrotal ultrasound with Doppler; if ultrasound is inconclusive for perfusion or identifies equivocal findings, the clinician orders a nuclear medicine test with radiopharmaceutical tracer to evaluate testicular perfusion.
Workflow: After order entry and informed consent, the nuclear medicine technologist prepares and injects the appropriate radiopharmaceutical tracer intravenously. Dynamic and static scrotal images are acquired to assess radiotracer uptake and perfusion of each testicle. The interpreting nuclear medicine physician reviews images and issues a report indicating normal perfusion, decreased perfusion consistent with torsion, or focal uptake suggesting tumor, cyst, or abscess. Results guide urgent surgical consultation for suspected torsion or alternative management for infectious or neoplastic causes. Typical site of service is an emergency department or hospital outpatient imaging suite staffed by nuclear medicine or radiology services.
