Physicians can improve coding decisions by better understanding needle-based and catheter-based thoracentesis techniques.
I have audited numerous radiology reports and it has become abundantly clear that a better understanding of the variations of a thoracentesis procedure is needed. Of course, in a perfect world the physician would give us the full description of the technique used and all guessing would be gone (from a coder’s perspective anyway). However, this is only in a perfect world and not in the true, fast-paced world our physicians are subjected to on a daily basis. I have gathered this information to better define the two thoracentesis techniques.
Thoracentesis is the process by which fluid is removed from the pleural space of the lungs. Fluid accumulation may be secondary to surgery, pneumonia, injury, heart failure, cancer, or other infections. This drainage process can occur with a needle or a catheter, depending on the physician’s technique.
There are two different types of thoracentesis, needle-based and catheter-based.
Thoracentesis (needle) is reported with 32421. When the procedure involves a needle aspiration without catheter placement, a 22 to 25-gauge needle is usually used, although there will be some variation in needle sizes. When coding needle aspiration thoracentesis (32421), the verbiage may take various forms, such as the following:
Thoracentesis (catheter) involves a puncture of the pleural space and insertion of a catheter for aspiration with the catheter withdrawn upon completion. A catheter procedure should be reported as 32422. This catheter is usually 3 to 6-French (F) in size. The catheter thoracentesis could be of any type (intracath, cannula, or Yueh needle/catheter). If the duration of its placement is not defined, the catheter is removed at the end of procedure.
When coding catheter thoracentesis (32422) you may see it mentioned in various ways, including the following:
I hope this information was of value and will help guide you to the correct concept.
