Thoracentesis
Ultrasound-guided [right / left] thoracentesis, [diagnostic / therapeutic]
[Right / Left] pleural effusion requiring [diagnostic thoracentesis for fluid analysis / therapeutic thoracentesis for symptomatic relief of dyspnea].
Informed consent was obtained from the [patient / patient's surrogate] after discussion of risks, benefits, and alternatives.
[***, MD/DO]
Local: [X] mL 1% lidocaine without epinephrine
Ultrasound showed a [right / left] pleural effusion measuring [X] cm in depth at the puncture site. The fluid appeared [anechoic / complex / echogenic] on ultrasound. [X] mL of [straw-colored / serosanguineous / bloody / turbid / milky] fluid was removed. Post-procedure ultrasound showed no pneumothorax.
A time-out was completed confirming the patient, procedure, and side. Pre-procedure INR was [value], and platelet count was [value].
The patient was positioned sitting upright, leaning forward with arms resting on a padded overbed table. Ultrasound was used to confirm the location and depth of the [right / left] pleural effusion and to identify the diaphragm, lung, and surrounding structures. The puncture site was marked at the [posterior / posterolateral] chest wall in the [X] intercostal space. An ultrasound image was saved documenting the effusion and the planned puncture site.
The skin was prepped with chlorhexidine and draped in sterile fashion. The skin, subcutaneous tissue, and periosteum of the superior rib margin were infiltrated with [X] mL of 1% lidocaine. A small skin nick was made with an 18-gauge needle.
A [thoracentesis needle / 8.5 Fr pigtail catheter] was advanced over the superior margin of the lower rib under ultrasound guidance with gentle aspiration. Entry into the pleural space was confirmed by free flow of pleural fluid, and the [catheter was advanced off the needle / catheter was deployed over a wire using Seldinger technique].
[Fluid was drained into vacuum bottles. Drainage was stopped when the effusion was fully drained or the patient developed [chest discomfort / persistent cough / a pressure sensation].] The [needle / catheter] was removed, and pressure was applied to the site.

The patient tolerated the procedure well, and oxygen saturation remained stable throughout. The patient will be monitored for 1 hour after the procedure. [A post-procedure chest radiograph is not indicated given an uncomplicated procedure without air aspiration / A post-procedure chest radiograph was ordered for [symptom change / air aspiration / technical difficulty]]. Pleural fluid results will be followed.

Diagnostic Thoracentesis (Small Volume)
Only 50–60 mL of pleural fluid was aspirated for diagnostic purposes. Fluid was sent for LDH, protein, albumin, pH, cell count with differential, Gram stain and culture, and cytology. Light's criteria will be applied to differentiate exudate from transudate.
Large-Volume Thoracentesis: Re-expansion Pulmonary Edema Precautions
Given the large effusion (>1000 mL anticipated), drainage was limited to 1500 mL in a single session. The patient was monitored during drainage for chest tightness, cough, and hypoxia. The patient tolerated drainage of [X] mL without these symptoms.
Post-Procedure Pneumothorax
Post-procedure chest radiograph demonstrated a [small / moderate] pneumothorax. The patient was [asymptomatic / symptomatic]. A [small-bore pigtail catheter / chest tube] was placed in the [right / left] pleural space with resolution of the pneumothorax on repeat imaging.
Charting Tips
- Document ultrasound image confirmation of effusion, depth measurement, and identification of the diaphragm. A permanently saved image is required to bill the imaging-guided service.
- Record total volume drained, fluid character, and all labs sent. For Light's criteria to be applied, LDH and protein must be measured in both the fluid and serum simultaneously. Note if serum labs were ordered.
- Document pre-procedure coagulation status (INR, platelets) if borderline. Most guidelines accept INR <2.0 and platelets >50,000 without correction for thoracentesis. Documenting these values protects against bleeding complication claims.
- Current evidence does not support a fixed 1500 mL drainage limit for routine therapeutic thoracentesis. Stop drainage for chest discomfort, persistent cough, or pressure sensation. During large-volume drainage, chest tightness, cough, or hypoxia should prompt immediate cessation because they can signal re-expansion pulmonary edema.
- A routine chest radiograph can be omitted after uncomplicated ultrasound-guided thoracentesis with no air aspirated. Obtain one for symptom change, air aspiration, or technical difficulty.
- Send pleural fluid triglycerides when chylothorax is suspected.
- A skin nick with an 18-gauge needle reduces drag on the catheter during insertion.
Documentation & Reimbursement Considerations
- Primary service: Report Thoracentesis as the primary service when it is the definitive operation performed.
- Thoracentesis without imaging guidance (1.77 wRVU, 0-day global) is reported for landmark-based needle aspiration of pleural fluid.
- Thoracentesis with imaging guidance (2.21 wRVU, 0-day global) is reported when real-time ultrasound is used. Document real-time needle visualization, a permanent image record, and medical necessity for guidance. Ultrasound guidance is now standard of care for thoracentesis, and most institutions use the imaging-guided service routinely.
- The imaging-guided service includes the guidance. Do not separately bill ultrasound guidance, because the guidance wRVU is bundled into the procedure.
- 0-day global: thoracentesis can be billed separately from a same-day E/M if a significant, separately identifiable evaluation is documented, with the appropriate modifier appended to the E/M.
- For recurrent malignant effusions requiring an indwelling pleural catheter, report a pleural catheter placement service rather than thoracentesis. Document the reason for indwelling catheter vs. repeat aspiration.
