Detect FWA Using Patterns in Procedure & Diagnosis Code Pairings
Payers can detect fraudulent billing schemes by analyzing certain CPT codes that are used in conjunction with ICD diagnosis codes and determining aberrant patterns, such as: a provider who bills a certain CPT code with the same diagnosis every time; a provider billing a certain CPT code with a diagnosis that does not support medical necessity; or an illogical number of a certain procedure billed within a time frame. An aberrant pattern, though not always fraudulent, can be investigated and the cause determined. For example, in a recently uncovered fraudulent billing scheme, a medical center in Oklahoma has settled a False Claims Act lawsuit for $1.5 million to resolve allegations it billed for medically unnecessary functional endoscopic sinus surgeries (FESS). The lawsuit involved an otolaryngologist who allegedly performed the FESS procedures on children who did not need them or had not been performed at all.
The FESS procedure is the most commonly-performed surgery for the treatment of conditions of the nasal sinus, including chronic sinusitis. Payers differ in their payment requirements, but generally may consider the surgery medically necessary for the following conditions, among others:
- Suspected tumor
- Suppurative complications
- Chronic polyposis
- Allergic fungal sinusitis
- Mucocele causing chronic sinusitis
- Recurrent sinusitis that aggravates pulmonary disease
- Other sinusitis that is unresponsive to medical therapy
The CPT codes used to report surgical nasal/sinus endoscopy are the following, depending upon other structures or associated procedures involved:
31237
Nasal/sinus endoscopy, surgical; with biopsy, polypectomy or debridement
31254
Nasal endoscopy, surgical; with ethmoidectomy, partial
31255
Nasal/sinus endoscopy, surgical; with ethmoidectomy, total (anterior and posterior)
31256
Nasal/sinus endoscopy, surgical, with maxillary antrostomy
31267
Nasal/sinus endoscopy, surgical, with maxillary antrostomy; removal of tissue from maxillary sinus
31288
Nasal/sinus endoscopy, surgical, with sphenoidotomy; with removal of tissue from the sphenoid sinus
