Official Description

Ultrasound, transrectal; prostate volume study for brachytherapy treatment planning (separate procedure)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 76873 refers to a specific ultrasound procedure known as a transrectal ultrasound for the purpose of conducting a prostate volume study. This procedure is particularly significant in the context of brachytherapy treatment planning, which involves the implantation of radioactive seeds to treat prostate cancer. During the transrectal ultrasound, a specialized ultrasound probe is carefully inserted into the rectum. This positioning allows for a clear view of the prostate gland and surrounding tissues. The ultrasound technique utilizes sound waves that are transmitted through the body tissues; these waves reflect off the tissues and return to the probe. The returning echoes are then converted into electrical signals, which are processed and displayed as images on a monitor. This imaging provides critical information regarding the size and shape of the prostate, which is essential for determining the most effective approach to brachytherapy. By accurately measuring the prostate volume, the physician can make informed decisions about the placement and dosage of radioactive beads, ultimately aiming to optimize treatment outcomes for patients diagnosed with prostate cancer.

1. Indications

The transrectal ultrasound procedure coded as CPT® 76873 is indicated for specific clinical scenarios related to prostate cancer treatment planning. The following conditions warrant the use of this procedure:

  • Prostate Cancer Diagnosis This procedure is performed to assist in the treatment planning for patients diagnosed with prostate cancer, particularly when considering brachytherapy as a treatment option.
  • Assessment of Prostate Volume The ultrasound is utilized to measure the size of the prostate gland, which is crucial for determining the appropriate treatment strategy and ensuring effective placement of radioactive seeds.
  • Evaluation of Prostate Anatomy The imaging helps in assessing the anatomical features of the prostate and surrounding tissues, which is important for planning the brachytherapy procedure.

2. Procedure

The transrectal ultrasound procedure involves several key steps that ensure accurate imaging and measurement of the prostate gland. The following procedural steps are outlined:

  • Step 1: Preparation The patient is positioned appropriately, typically lying on their side with knees drawn up to the chest, to facilitate the insertion of the ultrasound probe. The physician may provide instructions regarding bowel preparation to enhance imaging quality.
  • Step 2: Insertion of the Ultrasound Probe A lubricated transrectal ultrasound probe is gently inserted into the rectum. Care is taken to ensure patient comfort and minimize any discomfort during the procedure.
  • Step 3: Image Acquisition Once the probe is in place, the physician activates the ultrasound machine. High-frequency sound waves are emitted from the probe, which penetrate the tissues and reflect back to the probe. The machine processes these echoes to create real-time images of the prostate and surrounding structures.
  • Step 4: Measurement of Prostate Volume The physician analyzes the ultrasound images to measure the dimensions of the prostate gland. This measurement is critical for determining the appropriate treatment plan for brachytherapy.
  • Step 5: Completion of the Procedure After the necessary images and measurements are obtained, the probe is carefully removed. The physician may provide post-procedure instructions to the patient, including any necessary follow-up care.

3. Post-Procedure

Following the transrectal ultrasound procedure coded as CPT® 76873, patients may experience mild discomfort or transient rectal pressure, which typically resolves quickly. It is important for the physician to provide clear post-procedure instructions, which may include recommendations for monitoring any unusual symptoms, such as significant pain or bleeding. Patients are generally advised to resume normal activities as tolerated, but they should be informed about potential side effects, such as temporary changes in bowel habits. Follow-up appointments may be scheduled to discuss the ultrasound findings and to plan the next steps in the treatment process, particularly if brachytherapy is indicated.

26 Professional component: certain procedures are a combination of a physician or other qualified health care professional component and a technical component. when the physician or other qualified health care professional component is reported separately, the service may be identified by adding modifier 26 to the usual procedure number.
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.
TC Technical component; under certain circumstances, a charge may be made for the technical component alone; under those circumstances the technical component charge is identified by adding modifier 'tc' to the usual procedure number; technical component charges are institutional charges and not billed separately by physicians; however, portable x-ray suppliers only bill for technical component and should utilize modifier tc; the charge data from portable x-ray suppliers will then be used to build customary and prevailing profiles
XE Separate encounter, a service that is distinct because it occurred during a separate encounter
XS Separate structure, a service that is distinct because it was performed on a separate organ/structure
XU Unusual non-overlapping service, the use of a service that is distinct because it does not overlap usual components of the main service
50 Bilateral procedure: unless otherwise identified in the listings, bilateral procedures that are performed at the same session, should be identified by adding modifier 50 to the appropriate 5 digit code. note: this modifier should not be appended to designated "add-on" codes (see appendix d).
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).
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.
