Official Description

Tube thoracostomy, includes connection to drainage system (eg, water seal), when performed, open (separate procedure)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 32551 refers to tube thoracostomy, which is a surgical intervention aimed at draining fluid or air from the pleural space surrounding the lungs. This procedure is typically performed when there is an accumulation of fluid, known as pleural effusion, or air, known as pneumothorax, which can compromise lung function and lead to respiratory distress. During the procedure, the physician begins by cleansing the skin over the area where the tube will be inserted and administering a local anesthetic to minimize discomfort. A small incision is then made between the ribs, either on the side or the front of the chest, to access the pleural cavity. A trocar, which is a sharp instrument, is used to puncture the pleural cavity, allowing for the insertion of a plastic tube. This tube serves as a conduit for draining the accumulated fluid or air. Once the tube is in place, it may be connected to a drainage system, such as a water seal, which helps prevent any backflow of air or fluid into the chest cavity. Additionally, suction may be applied to facilitate the drainage process. The tube remains in situ until the pleural space is adequately drained and the lungs have re-expanded, ensuring that normal respiratory function can be restored.

1. Indications

The tube thoracostomy procedure, as described by CPT® Code 32551, is indicated for several specific clinical conditions that necessitate the removal of fluid or air from the pleural space. These indications include:

  • Pleural Effusion - The accumulation of excess fluid in the pleural cavity, which can lead to difficulty breathing and reduced lung capacity.
  • Pneumothorax - The presence of air in the pleural space, which can cause lung collapse and significant respiratory distress.
  • Hemothorax - The collection of blood in the pleural cavity, often resulting from trauma or other medical conditions that require immediate drainage.
  • Empyema - The presence of pus in the pleural space, typically due to infection, necessitating drainage to prevent further complications.

2. Procedure

The tube thoracostomy procedure involves several critical steps to ensure effective drainage of the pleural space. The steps are as follows:

  • Preparation - The physician begins by preparing the patient for the procedure, which includes cleansing the skin over the insertion site and administering a local anesthetic to minimize pain during the intervention.
  • Incision - A small incision is made between the ribs on either the side or the front of the chest, providing access to the pleural cavity. This incision is strategically placed to optimize drainage and minimize discomfort.
  • Puncture - A trocar is then utilized to puncture the pleural cavity. This instrument allows for the creation of an opening through which the drainage tube can be inserted.
  • Insertion of the Tube - Following the puncture, a small track is created through the chest wall, and a plastic tube is carefully inserted into the pleural cavity. This tube is designed to facilitate the drainage of fluid or air.
  • Connection to Drainage System - Once the tube is in place, it is connected to a thoracic drainage and collection system. A water seal system may be employed to prevent any leakage back into the chest cavity, ensuring that the pleural space remains effectively drained.
  • Application of Suction - Suction may be applied to the collection system to enhance the drainage of air or fluid from the pleural space, promoting lung re-expansion.
  • Monitoring - The physician monitors the patient and the drainage system to ensure that the procedure is successful and that the lungs are re-expanding appropriately.

3. Post-Procedure

After the tube thoracostomy procedure, the patient is typically monitored for any complications and to assess the effectiveness of the drainage. The chest tube remains in place until the pleural space is adequately drained, and the lungs have re-expanded, which may take several hours to days depending on the underlying condition. Patients may experience some discomfort at the insertion site, which can be managed with analgesics. Regular assessments of the drainage output and the patient's respiratory status are essential to ensure proper recovery. Once the physician determines that drainage is complete and the lungs are functioning normally, the chest tube can be safely removed. Follow-up care may include imaging studies to confirm lung re-expansion and further evaluation of the underlying condition that necessitated the procedure.

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).
X4 Episodic/focused services: for reporting services by clinicians who provide focused care on particular types of treatment limited to a defined period and circumstance; the patient has a problem, acute or chronic, that will be treated with surgery, radiation, or some other type of generally time-limited intervention; reporting clinician service examples include but are not limited to, the orthopedic surgeon performing a knee replacement and seeing the patient through the postoperative period
AS Physician assistant, nurse practitioner, or clinical nurse specialist services for assistant at surgery
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).
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.
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).
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.
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.
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.
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.)
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
