Official Description

Thoracentesis, needle or catheter, aspiration of the pleural space; without imaging guidance

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

Thoracentesis is a medical procedure aimed at removing excess fluid from the pleural space, which is the area between the parietal and visceral pleura that encase the lungs. This procedure is essential for diagnosing and treating various conditions that lead to fluid accumulation, such as pleural effusion. During thoracentesis, the patient is typically positioned seated, with their head and arms resting on a table to facilitate access to the pleural cavity. The skin surrounding the intended site of the procedure is thoroughly cleansed and draped to maintain a sterile environment. A local anesthetic is then administered to minimize discomfort during the procedure. The physician carefully inserts a needle or catheter between the ribs into the pleural cavity to aspirate the fluid. It is important to note that CPT® Code 32554 is specifically used when this procedure is performed without the aid of imaging guidance, distinguishing it from CPT® Code 32555, which is applicable when imaging techniques such as ultrasound, fluoroscopy, or CT are utilized to assist in the accurate placement of the needle.

1. Indications

Thoracentesis is indicated for the following conditions:

  • Pleural Effusion - The accumulation of excess fluid in the pleural space, which may be due to various underlying conditions such as heart failure, pneumonia, or malignancy.
  • Diagnostic Purposes - To obtain pleural fluid for laboratory analysis to determine the cause of the effusion, including infection, cancer, or inflammatory diseases.
  • Therapeutic Relief - To alleviate symptoms caused by fluid accumulation, such as shortness of breath or chest discomfort, by reducing the pressure on the lungs.

2. Procedure

The procedure of thoracentesis involves several critical steps to ensure safety and effectiveness:

  • Preparation of the Patient The patient is positioned in a seated manner, often leaning forward with their head and arms resting on a table. This position helps to expand the pleural space and provides better access for the procedure. The skin around the intended puncture site is then cleansed with an antiseptic solution to minimize the risk of infection.
  • Draping and Anesthesia After cleansing, the area is draped with sterile coverings to maintain a sterile field. A local anesthetic is administered to numb the area where the needle will be inserted, ensuring that the patient experiences minimal discomfort during the procedure.
  • Needle Insertion The physician carefully identifies the appropriate intercostal space, typically using anatomical landmarks, and inserts a needle or catheter between the ribs into the pleural cavity. The insertion is done with precision to avoid injury to surrounding structures.
  • Fluid Aspiration Once the needle is correctly positioned within the pleural space, the physician withdraws fluid through the needle. The amount of fluid aspirated may vary depending on the clinical situation and the volume of fluid present in the pleural cavity.
  • Completion of the Procedure After the desired amount of fluid has been collected, the needle is carefully removed, and pressure is applied to the site to minimize bleeding. A sterile dressing is then placed over the puncture site to protect it.

3. Post-Procedure

Post-procedure care for thoracentesis includes monitoring the patient for any immediate complications, such as bleeding or pneumothorax. Patients are typically observed for a short period to ensure stability. Instructions may be provided regarding activity restrictions and signs of potential complications to watch for, such as increased shortness of breath, chest pain, or fever. Follow-up appointments may be scheduled to review laboratory results from the aspirated fluid and to assess the patient's condition.

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).
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).
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.)
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.
74 Discontinued out-patient hospital/ambulatory surgery center (asc) procedure after administration of anesthesia: due to extenuating circumstances or those that threaten the well being of the patient, the physician may terminate a surgical or diagnostic procedure after the administration of anesthesia (local, regional block(s), general) or after the procedure was started (incision made, intubation started, scope inserted, etc). under these circumstances, the procedure started but terminated can be reported by its usual procedure number and the addition of modifier 74. note: the elective cancellation of a service prior to the administration of anesthesia and/or surgical preparation of the patient should not be reported. for physician reporting of a discontinued procedure, see modifier 53.
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.)
