It works: Empire Medicare covers rhinometry thanks to this coder's digging
If you shudder at the sight of rhinometry denials, we've got the answers you need to glide through your next claim on your first try.
Consider this acoustic rhinometry (AR) case study. One coder reveals the documentation she used to overturn an insurer's view of the test as experimental. Including this documentation with your claim could help you avoid
a denial. The service: Physicians are using new diagnostic test to evaluate chronic rhinitis (472.0), notes physician David Plaxico with Allergy & Asthma Clinic of Macon in Georgia.
Many insurers have policies that deem rhinometry experimental and investigational. For instance, Aetna won't cover 92512 (Nasal function studies [e.g., rhinomanometry]) in part because "clinical studies have not demonstrated that rhinomanometry and acoustic rhinometry improve clinical outcomes," according to Aetna's "Clinical Policy Bulletin: Rhinomanometry and Acoustic Rhinometry" (visit
www.aetna.com/cpb/medical/data/700_799/0700.html).
But showing payors a series of documents might make them change their tune.
Step 1: Show That Related Devices Are FDA-Approved
In the battle for 92512 coverage, expect insurers to first want evidence that the device is a Food and Drug Administration-approved product. Before covering 92512, Empire Blue Cross Blue Shield (Medicare Part B for New Jersey and New York state) required such proof, says Laura Colbert Carbonaro, director of central billing operations for ENT and Allergy Associates in Tarrytown, NY.
A phone call to the FDA resulted in a letter pointing Carbonaro to the documentation Empire BCBS required. "E. Benson Hood Lab Inc. received FDA marketing clearance on July 26, 2002, for their rhinoanemometer (FDA #K011329)," confirmed Bonnie J. Alderton, public health adviser at the FDA's Center for Devices and Radiological Health.
Even better: Alderton identified the Web site of a copy of the clearance letter the FDA sent the firm upon clearing its device, which you can use in your fight. Find it at

Step 2: Tell the Payor What The Service Is
You can't hope to convince an insurer to cover a test if the representative has no clue what the device is.
Solution: Provide a low-key explanation of rhinometry, such as this definition: "Acoustic rhinometry (AR) is a quick, painless, noninvasive and reproducible method for examination of the nasal cavity using a sound pulse technique," write the medical authors of "An Interpretation Method for Objective Assessment of Nasal Congestion With Acoustic Rhinometry" in Laryngoscope, 112: 926-929, 2002.
Step 3: Illustrate the Benefits of the Service
Carbonaro didn't stop there. She also gathered information supporting the benefits of acoustic rhinometry in a ready-to-go package. To make an insurance representative reconsider his company's policy that 92512 is noncovered as investigational or experimental, point to the following scholarly article that demonstrates rhinometry's efficacy.
