Official Description

Replacement, catheter only, of central venous access device, with subcutaneous port or pump, central or peripheral insertion site

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 36578 refers to the procedure of replacing a catheter only for a central venous access device that includes a subcutaneous port or pump, which can be inserted through either a central or peripheral site. This procedure is essential for patients who require long-term venous access for therapies such as chemotherapy, total parenteral nutrition, or frequent blood draws. During the catheter replacement, the existing catheter is carefully evaluated for any occlusions or damage, ensuring that the integrity of the venous access is maintained. The subcutaneous pocket, where the port or pump resides, is surgically opened to allow for inspection and replacement of the catheter. The procedure involves the use of a guidewire to facilitate the removal of the old catheter and the insertion of a new one, ensuring that the catheter tip is correctly positioned in a major vein, such as the subclavian, brachiocephalic, iliac vein, superior or inferior vena cava, or right atrium. This meticulous process is crucial for maintaining effective venous access and preventing complications associated with catheter malfunction or infection.

1. Indications

The procedure described by CPT® Code 36578 is indicated for patients who require replacement of a central venous access device due to various reasons. These indications may include:

  • Catheter Occlusion The existing catheter may be occluded, preventing proper flow of fluids or medications.
  • Catheter Damage The catheter may be damaged, which can compromise its function and increase the risk of complications.
  • Infection Risk If there is a risk of infection associated with the current catheter, replacement may be necessary to ensure patient safety.
  • Device Malfunction The port or pump may not be functioning correctly, necessitating a replacement to restore proper access.

2. Procedure

The procedure for replacing a catheter in a central venous access device involves several critical steps:

  • Step 1: Preparation The patient is positioned appropriately, and the area around the subcutaneous port or pump is cleaned and sterilized to minimize the risk of infection.
  • Step 2: Accessing the Subcutaneous Pocket A surgical incision is made to open the subcutaneous pocket where the port or pump is located. This allows for direct access to the device for inspection and replacement.
  • Step 3: Examination of the Port or Pump The port or pump is examined to ensure it is functioning correctly. This step is crucial to confirm that the device can effectively deliver medications or fluids after the new catheter is placed.
  • Step 4: Radiographic Verification Radiographs may be obtained to verify the position of the existing catheter tip, ensuring it is correctly placed within the vascular system.
  • Step 5: Catheter Removal A guidewire is inserted through the existing catheter, which is then carefully withdrawn over the guidewire. This technique helps maintain access to the vein during the replacement process.
  • Step 6: Insertion of New Catheter A new catheter is advanced over the guidewire into the appropriate position within the vascular system, such as the subclavian, brachiocephalic, iliac vein, superior or inferior vena cava, or right atrium.
  • Step 7: Connection and Leak Testing The new catheter is connected to the port or pump device. The connection is checked for leaks by injecting intravenous fluid, ensuring that the system is secure and functional.
  • Step 8: Closure The port or pump is returned to the subcutaneous pocket, and the pocket is secured with sutures to close the incision site, completing the procedure.

3. Post-Procedure

After the catheter replacement procedure, the patient is monitored for any immediate complications, such as bleeding or signs of infection at the incision site. Instructions for care of the site and the new catheter are provided, including how to recognize signs of potential complications. Follow-up appointments may be scheduled to assess the function of the new catheter and ensure that the port or pump is operating correctly. Patients are advised to maintain proper hygiene and to report any unusual symptoms, such as fever or swelling, to their healthcare provider promptly.

22 Increased procedural services: when the work required to provide a service is substantially greater than typically required, it may be identified by adding modifier 22 to the usual procedure code. documentation must support the substantial additional work and the reason for the additional work (ie, increased intensity, time, technical difficulty of procedure, severity of patient's condition, physical and mental effort required). note: this modifier should not be appended to an e/m service.
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).
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.
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.
78 Unplanned return to the operating/procedure room by the same physician or other qualified health care professional following initial procedure for a related procedure during the postoperative period: it may be necessary to indicate that another procedure was performed during the postoperative period of the initial procedure (unplanned procedure following initial procedure). when this procedure is related to the first, and requires the use of an operating/procedure room, it may be reported by adding modifier 78 to the related procedure. (for repeat procedures, see modifier 76.)
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.)
