CPT 74742: Fallopian Tube Catheterization for Diagnosis or Reestablishing Patency

CPT code 74742 represents physician-performed catheterization of a fallopian tube to diagnose blockages or restore patency. This procedure is clinically important in the evaluation and management of tubal-factor infertility and can influence subsequent reproductive care pathways. Nationally, it is performed in outpatient surgical centers and hospital outpatient departments and has implications for fertility treatment planning and resource utilization.

Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication provides an overview of clinical context, coding guidance, common modifiers, and what payers commonly cover for this type of service. Readers will find benchmarks and policy-relevant summaries that clarify how 74742 fits into procedural coding for gynecologic interventions, as well as considerations for claims processing and site-of-service differences.

This summary is intended for clinicians, billing professionals, and policy analysts who need a concise reference to the clinical purpose of CPT code 74742, the typical care settings where it is performed, and the payer landscape relevant to the procedure. Data not available in the input is noted where applicable.

Clinical & Coding Specifications

Clinical Context

A typical patient is a reproductive-aged woman presenting for evaluation of infertility after 6–12 months of unsuccessful attempts to conceive. Prior imaging (hysterosalpingography or pelvic ultrasound) suggests possible fallopian tube occlusion or proximal tubal block. The gynecologist schedules a diagnostic and potential therapeutic fallopian tube catheterization under fluoroscopic guidance. The procedure is performed in an outpatient radiology or ambulatory surgery setting or in an operating room if combined with laparoscopy. The patient undergoes local anesthesia with sedation or general anesthesia per provider and payer policy. A transcervical catheter is introduced into the uterine cavity and advanced into the ostium of the fallopian tube; contrast is injected under fluoroscopy to confirm patency. If a proximal obstruction is identified, catheter manipulation or microcatheter techniques are used to attempt to reestablish patency. Postprocedure monitoring occurs in recovery until stable for discharge. Documentation includes indication, consent, preprocedural imaging, anesthesia type, procedural steps (catheterization, contrast volumes, fluoroscopic time), findings (patent vs obstructed tube), any therapeutic maneuvers performed, complications, and discharge instructions.

Coding Specifications

Modifier	Description	When to Use
`26`	Professional component	Use when only the physician interpretation/professional work is billed separately from technical services.
`50`	Bilateral procedure	Use when catheterization/attempts are performed on both fallopian tubes and payer requires bilateral modifier.
`52`	Reduced services	Use when the procedure is partially reduced or not completed as originally planned.
`53`	Discontinued procedure	Use if the procedure is started but stopped due to patient instability or unexpected findings.
`62`	Two simultaneous surgeons	Use if two surgeons work together as primary surgeons for complex intraoperative issues.
`78`	Return to OR for related procedure during global period	Use if patient returns to the operating room for a related complication during the global period.
`79`	Unrelated procedure or service by the same physician during global period	Use if an unrelated procedure is performed during the global period.
`80`	Assistant surgeon	Use when an assistant surgeon participates and payer requires modifier for payment.
`81`	Minimum assistant surgeon	Use when only minimal assistance was provided and payer recognizes this modifier.
`22`	Increased procedural services	Use when work required is substantially greater than usual (document rationale).
`23`	Unusual anesthesia	Use when general anesthesia is required for circumstances where local/regional is typical.
`24`	Unrelated E/M service during postoperative period	Use when an unrelated evaluation and management service is provided during the global period.
`26`	Professional component	Use when radiology or procedural interpretation is billed separately from technical component.
`52`	Reduced services	Use when procedure is partially performed with reduced work or time.
`53`	Discontinued procedure	Use when terminated prior to completion for patient-related or medical reasons.

Taxonomy Code	Specialty	Notes
208000000X	Obstetrics & Gynecology	Gynecologists commonly perform or coordinate fallopian tube catheterization.
207V00000X	Reproductive Endocrinology & Infertility	Specialists in infertility management performing diagnostic/therapeutic tubal procedures.
261Q00000X	Diagnostic Radiology	Interventional radiologists may perform fluoroscopically guided tubal catheterization.

Related Diagnoses

ICD-10 Code	Description	Clinical Relevance
`N97.0`	Female infertility due to tubal origin	Primary indication for fallopian tube catheterization to diagnose and treat tubal occlusion.
`N96`	Habitual aborter (recurrent pregnancy loss)	Evaluation may include tubal assessment when tubal factors are suspected contributors to pregnancy loss.
`N70.1`	Acute salpingitis and oophoritis	Active infection is a consideration; procedure is deferred until infection controlled; history indicates tubal damage risk.
`N73.6`	Female pelvic inflammatory disease, chronic	Chronic PID often causes tubal scarring and obstruction prompting catheterization attempts.
`N80.0`	Endometriosis of uterus	Endometriosis involving tubes can cause obstruction; catheterization may be part of diagnostic/therapeutic approach.
