Official Description

Catheterization and introduction of saline or contrast material for saline infusion sonohysterography (SIS) or hysterosalpingography

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 58340 involves the catheterization and introduction of saline or contrast material into the uterus for the purposes of saline infusion sonohysterography (SIS) or hysterosalpingography. In SIS, the physician begins by performing a baseline transvaginal ultrasound to assess the uterine cavity. Following this initial imaging, a speculum is inserted to allow access to the cervix, which is then cleansed to ensure a sterile environment. A small-diameter flexible catheter is carefully placed through the cervix and into the uterine cavity. After the catheter is positioned, the speculum is removed, and the transvaginal ultrasound probe is reinserted to visualize the uterus. Sterile saline or contrast media is then instilled through the catheter into the uterine cavity, expanding it adequately for detailed imaging. In the case of hysterosalpingography, the catheterization process is similar; however, after the speculum is removed, fluoroscopy is utilized to visualize the uterus and Fallopian tubes as the contrast media is introduced. This procedure is essential for evaluating uterine abnormalities and assessing the patency of the Fallopian tubes, providing critical information for further management of reproductive health issues.

1. Indications

The procedure described by CPT® Code 58340 is indicated for the following conditions:

  • Evaluation of Uterine Abnormalities This procedure is performed to assess for structural abnormalities within the uterus, such as fibroids, polyps, or congenital anomalies that may affect reproductive health.
  • Assessment of Fallopian Tube Patency Hysterosalpingography is specifically indicated to determine whether the Fallopian tubes are open (patent) or blocked, which is crucial for evaluating infertility issues.
  • Investigation of Abnormal Uterine Bleeding The procedure may be indicated in cases of abnormal uterine bleeding to identify potential causes related to uterine structure.

2. Procedure

The procedure involves several key steps to ensure accurate imaging and assessment of the uterine cavity and Fallopian tubes:

  • Step 1: Baseline Transvaginal Ultrasound The physician begins by performing a baseline transvaginal ultrasound to visualize the uterus and assess any pre-existing conditions. This initial imaging is crucial for establishing a reference point before the introduction of saline or contrast material.
  • Step 2: Insertion of Speculum After the ultrasound, a speculum is inserted into the vagina to provide access to the cervix. This step is essential for the subsequent cleansing and catheterization process.
  • Step 3: Cleansing of Cervical Os The cervical os is cleansed through the speculum to maintain a sterile environment, reducing the risk of infection during the procedure.
  • Step 4: Catheter Placement A small-diameter flexible catheter is then carefully placed through the cervix and into the uterine cavity. This step requires precision to ensure that the catheter is correctly positioned for the infusion of saline or contrast material.
  • Step 5: Removal of Speculum and Re-insertion of Ultrasound Probe Once the catheter is in place, the speculum is removed, and the transvaginal ultrasound probe is reinserted to continue visualizing the uterus during the procedure.
  • Step 6: Instillation of Saline or Contrast Media Sterile saline or contrast media is instilled into the uterine cavity through the catheter. This infusion expands the uterine cavity, allowing for better visualization and assessment during the ultrasound or fluoroscopy.
  • Step 7: Visualization with Fluoroscopy (for Hysterosalpingography) In cases of hysterosalpingography, after the speculum is removed, fluoroscopy is utilized to visualize the uterus and Fallopian tubes as the contrast media is instilled, providing real-time imaging to assess patency and any abnormalities.

3. Post-Procedure

After the completion of the procedure, patients may be monitored for any immediate complications or discomfort. It is common for patients to experience mild cramping or spotting following the procedure. Healthcare providers may offer guidance on post-procedure care, including recommendations for pain management and activity restrictions. Patients are typically advised to report any unusual symptoms, such as heavy bleeding or severe pain, to their healthcare provider. Follow-up appointments may be scheduled to discuss the results of the imaging and any further management based on the findings.

59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.
51 Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d).
GA Waiver of liability statement issued as required by payer policy, individual case
52 Reduced services: under certain circumstances a service or procedure is partially reduced or eliminated at the discretion of the physician or other qualified health care professional. under these circumstances the service provided can be identified by its usual procedure number and the addition of modifier 52, signifying that the service is reduced. this provides a means of reporting reduced services without disturbing the identification of the basic service. note: for hospital outpatient reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well-being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for asc hospital outpatient use).
53 Discontinued procedure: under certain circumstances, the physician or other qualified health care professional may elect to terminate a surgical or diagnostic procedure. due to extenuating circumstances or those that threaten the well being of the patient, it may be necessary to indicate that a surgical or diagnostic procedure was started but discontinued. this circumstance may be reported by adding modifier 53 to the code reported by the individual for the discontinued procedure. note: this modifier is not used to report the elective cancellation of a procedure prior to the patient's anesthesia induction and/or surgical preparation in the operating suite. for outpatient hospital/ambulatory surgery center (asc) reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for asc hospital outpatient use).
58 Staged or related procedure or service by the same physician or other qualified health care professional during the postoperative period: it may be necessary to indicate that the performance of a procedure or service during the postoperative period was: (a) planned or anticipated (staged); (b) more extensive than the original procedure; or (c) for therapy following a surgical procedure. this circumstance may be reported by adding modifier 58 to the staged or related procedure. note: for treatment of a problem that requires a return to the operating/procedure room (eg, unanticipated clinical condition), see modifier 78.
76 Repeat procedure or service by same physician or other qualified health care professional: it may be necessary to indicate that a procedure or service was repeated by the same physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 76 to the repeated procedure or service. note: this modifier should not be appended to an e/m service.
77 Repeat procedure by another physician or other qualified health care professional: it may be necessary to indicate that a basic procedure or service was repeated by another physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 77 to the repeated procedure or service. note: this modifier should not be appended to an e/m service.
79 Unrelated procedure or service by the same physician or other qualified health care professional during the postoperative period: the individual may need to indicate that the performance of a procedure or service during the postoperative period was unrelated to the original procedure. this circumstance may be reported by using modifier 79. (for repeat procedures on the same day, see modifier 76.)
