49083

Abdominal paracentesis, initial, or subsequent; without imaging guidance

CPT code 49083 represents the percutaneous puncture of the abdominal cavity for the aspiration and/or drainage of intra-abdominal fluid (e.g., ascites) or an abscess, performed without the use of any imaging guidance (such as ultrasound, CT, or fluoroscopy). This procedure is typically carried out when the fluid collection is clinically apparent, easily palpable, or the operator is highly confident of its location based on physical examination, negating the need for image-guided assistance. The service includes the insertion of a needle or catheter into the peritoneal cavity to obtain fluid for diagnostic analysis or to remove large volumes of fluid for therapeutic relief.

Clinical Indications

  • Symptomatic ascites causing discomfort, abdominal distension, dyspnea, or impaired mobility.
  • Diagnosis of spontaneous bacterial peritonitis (SBP) in patients with ascites and suspected infection.
  • Evaluation of new-onset ascites for underlying etiology (e.g., malignancy, heart failure, liver disease).
  • Therapeutic drainage of refractory ascites that is unresponsive to medical management.
  • Drainage of a clinically apparent intra-abdominal or peritoneal abscess.
  • Malignant ascites causing significant symptoms.

Procedure Steps

  1. Patient positioning (typically supine or semi-recumbent) and sterile preparation of the chosen insertion site on the abdomen.
  2. Administration of local anesthetic to the skin, subcutaneous tissue, and peritoneum at the puncture site.
  3. Insertion of a needle or small catheter through the abdominal wall into the peritoneal cavity or fluid collection.
  4. Aspiration of peritoneal fluid for diagnostic analysis (e.g., cell count, albumin, total protein, glucose, LDH, bacterial culture, cytology).
  5. Therapeutic drainage of a desired volume of fluid, if indicated, by gravity or gentle suction.
  6. Removal of the needle/catheter and application of a sterile dressing to the puncture site.
  7. Post-procedure monitoring for complications such as hemorrhage, infection, or leakage.

Coding Guidelines

  • This code specifically applies to abdominal paracentesis performed without any form of imaging guidance. If imaging guidance (e.g., ultrasound, CT, fluoroscopy) is utilized, a different CPT code (e.g., 49082 for initial, or 49084 for subsequent, both with imaging guidance) must be reported.
  • Do not report 49083 in conjunction with codes for imaging guidance (e.g., 76942, 77002, 77012, 77021), as the absence of imaging is intrinsic to the definition of this code.
  • This code encompasses both the initial and any subsequent paracentesis procedures performed without imaging guidance during the same episode of care, provided separate, distinct indications exist for subsequent procedures.
  • Documentation must clearly state that no imaging guidance was employed for the procedure.
  • This code is typically subject to a 0-day global period, meaning that post-procedure care provided on the same day as the procedure is usually included in the service.
