Official Description

Repair of cardiac wound; with cardiopulmonary bypass

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 33305 involves the repair of a cardiac wound while utilizing cardiopulmonary bypass. A cardiac wound refers to any injury or defect in the heart that requires surgical intervention. In contrast to CPT® Code 33300, which details the repair of a cardiac wound without the use of cardiopulmonary bypass (known as off-pump cardiac wound repair), this procedure is performed with the heart temporarily stopped and blood circulation maintained by a heart-lung machine. The surgical approach begins with an incision in the chest to access the heart, allowing the surgeon to control any bleeding and assess the extent of the cardiac injury. During the procedure, blood is evacuated from the thoracic cavity, and the pericardium, the protective sac surrounding the heart, may be incised to relieve any fluid accumulation. A traction suture, often referred to as a Beck's suture, is placed to stabilize the heart during the repair process. The surgeon then identifies the location of the cardiac wound and employs various techniques to control bleeding, depending on the size of the wound. If the wound is small, digital pressure or temporary sutures may be used, while larger wounds may necessitate clamping of major blood vessels to create a bloodless field. After thorough evaluation and control of bleeding, the cardiac wound is closed using permanent sutures, ensuring that surrounding structures, such as coronary arteries, are not damaged. The procedure concludes with the removal of the traction suture, placement of chest tubes if necessary, and closure of the chest cavity.

1. Indications

The procedure described by CPT® Code 33305 is indicated for the repair of cardiac wounds that require surgical intervention under cardiopulmonary bypass. The following conditions may warrant this procedure:

  • Cardiac Wound A defect or injury to the heart that necessitates surgical repair.
  • Severe Bleeding Uncontrolled bleeding from the heart that cannot be managed through less invasive means.
  • Cardiac Trauma Injuries resulting from blunt or penetrating trauma to the chest that affect cardiac structures.
  • Coronary Artery Damage Potential damage to coronary arteries that may require evaluation and repair during the procedure.

2. Procedure

The procedure for the repair of a cardiac wound with cardiopulmonary bypass involves several critical steps:

  • Step 1: Chest Opening The surgeon begins by making an incision in the chest to access the heart. This allows for direct visualization and control of the cardiac wound.
  • Step 2: Blood Evacuation Once the chest is opened, any blood present in the thoracic cavity is evacuated to provide a clear surgical field and to assess the extent of the injury.
  • Step 3: Pericardial Incision If necessary, the pericardium may be incised to release any fluid accumulation in the pericardial cavity, further facilitating access to the heart.
  • Step 4: Placement of Traction Suture A traction suture, known as a Beck's suture, is placed to stabilize the heart and allow for better control during the repair process.
  • Step 5: Wound Identification The surgeon locates the site of the cardiac wound, assessing its size and severity to determine the appropriate method for controlling bleeding.
  • Step 6: Bleeding Control For small wounds, bleeding may be controlled using digital pressure or temporary sutures. For larger wounds, the inferior and superior vena cava may be clamped to create a bloodless field.
  • Step 7: Evaluation of Cardiac Structures After controlling the bleeding, the surgeon evaluates the cardiac wound to check for any damage to coronary arteries or other heart structures.
  • Step 8: Wound Closure If no additional injuries are found, the cardiac wound is closed using mattress sutures reinforced with pledgets to ensure a secure closure while avoiding injury to surrounding vessels.
  • Step 9: Final Steps The traction suture is removed, chest tubes are placed as needed to drain any fluid, and the chest cavity is closed to complete the procedure.

3. Post-Procedure

After the completion of the cardiac wound repair with cardiopulmonary bypass, patients typically require close monitoring in a postoperative setting. This includes observation for any signs of complications such as bleeding, infection, or arrhythmias. The recovery process may involve the management of pain and the administration of medications to support heart function. Patients may also need to undergo rehabilitation to regain strength and function following the surgery. The duration of recovery can vary based on the individual’s overall health and the complexity of the procedure performed.

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).
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.
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.
62 Two surgeons: when 2 surgeons work together as primary surgeons performing distinct part(s) of a procedure, each surgeon should report his/her distinct operative work by adding modifier 62 to the procedure code and any associated add-on code(s) for that procedure as long as both surgeons continue to work together as primary surgeons. each surgeon should report the co-surgery once using the same procedure code. if additional procedure(s) (including add-on procedure(s) are performed during the same surgical session, separate code(s) may also be reported with modifier 62 added. note: if a co-surgeon acts as an assistant in the performance of additional procedure(s), other than those reported with the modifier 62, during the same surgical session, those services may be reported using separate procedure code(s) with modifier 80 or modifier 82 added, as appropriate.
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.
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.)
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
82 Assistant surgeon (when qualified resident surgeon not available): the unavailability of a qualified resident surgeon is a prerequisite for use of modifier 82 appended to the usual procedure code number(s).
