Coding Nasal Sinus
Share this:

Functional endoscopic sinus surgery is recommended and commonly performed for infectious and inflammatory sinus disease. The patients must have documented rhinosinusitis, and the surgery is recommended on the basis of a thorough history and a complete physical examination. Patients are usually those in whom appropriate medical treatment has failed.

The procedure can be performed on an outpatient basis under local or general anesthesia. Health insurance policies cover this service when it is medically necessary. The Centers for Medicare and Medicaid Services (CMS) released the 2014 Final Rule in November 2013, updating the hospital outpatient prospective payment system (OPPS). Now, Medicare reimburses outpatient services according to the updated OPPS which bases payment on Ambulatory Payment Classifications (APCs). So, the surgeons are required to use relevant codes to specify APC as well. Diagnostic codes are essential to ensure the surgical procedure was performed for a reimbursable health issue (ensure medically necessary procedure). Let’s take a look at some of the CPT codes and related APC and diagnostic codes.

Tips for Accurate Coding

  • Use code 30140 only if the documentation indicates the mucosa was entered/incised and preserved and tissue and/or bone were removed. If there is a statement “excised the turbinate(s)”, it is not enough to consider the submucous resection of the inferior turbinate(s) and would not support 30140.
  • Do not report 31254 – 31288 in conjunction with the balloon dilation codes, 31295-31297 for the procedures performed on the same sinus.
  • Apply balloon dilation codes for cases in which a balloon catheter is the only instrument or tool used to create the opening and no tissue is removed.
  • Use balloon dilation codes when tissue is displaced. If tissue and/or bone are removed or tissue is both displaced and removed, then see codes 31254-31288.
  • Do not report 31295 in conjunction with 31233, 31256, or 31267 if performed on the same sinus.
  • Do not report 31296 in conjunction with 31276 if performed on the same sinus.
  • Do not report 31297 in conjunction with 31235, 31287, or 31288 if performed on the same sinus.
  • Do not separately report a lavage code (31000 or 31002) with the balloon dilation codes.
