Summary & Overview
CPT 58340: Uterine and Fallopian Tube Catheterization with Saline or Contrast
CPT code 58340 describes catheterization of the uterus with infusion of saline or contrast material during ultrasound or X‑ray to evaluate the uterus and fallopian tubes for blockages or structural abnormalities. This diagnostic procedure supports fertility assessment and evaluation of abnormal uterine bleeding or suspected tubal pathology and is performed in imaging-equipped outpatient settings. Nationally, the code is relevant because it captures a common, imaging‑guided gynecologic diagnostic service that intersects radiology and reproductive health care delivery.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context for 58340, the typical service settings and clinical indications, and what to expect in payer coverage patterns and billing practice. The report summarizes common modifiers and billing considerations when present, highlights policy and documentation themes that affect claim adjudication, and provides benchmarking and reimbursement context where available. Data not available in the input is noted when applicable.
Billing Code Overview
CPT code 58340 describes catheterization of the uterus and introduction of saline or contrast material for uterine and fallopian tube evaluation performed with ultrasound or X-ray guidance. The procedure is used to examine the uterus and fallopian tubes for blockages or abnormalities and includes catheter placement with instillation of saline for saline infusion sonohysterography (SIS) or contrast for hysterosalpingography.
-
Service type: Diagnostic radiologic or sonographic uterine and tubal evaluation involving catheterization and contrast or saline infusion.
-
Typical site of service: Outpatient imaging center, radiology department, or ambulatory surgery center where ultrasound or fluoroscopic X-ray imaging is available.
Clinical & Coding Specifications
Clinical Context
A 32-year-old woman with a 12-month history of infertility and irregular menses is referred to a reproductive health clinic for evaluation of uterine cavity and tubal patency. Prior transvaginal ultrasound suggested a possible intrauterine synechia. The clinician schedules a saline infusion sonohysterography with catheter placement under ultrasound guidance to evaluate the uterine cavity and fallopian tubes for polyps, adhesions, septa, or tubal occlusion. The procedure is performed in an outpatient imaging suite. The patient arrives after obtaining informed consent, a brief focused history, and no contraindications to intrauterine instrumentation (no active pelvic infection, pregnancy excluded). A transvaginal probe is placed, sterile technique is used to pass a small transcervical catheter into the uterine cavity, and saline (or sterile contrast if radiographic imaging is chosen) is instilled while real-time ultrasound (or fluoroscopy) images are obtained to document cavity contour and contrast spill from the tubal ostia. Postprocedure instructions are given and findings documented in the medical record, including indication, imaging findings, any immediate complications, and whether additional interventions are recommended.
