Payer Coverage of Valley Fever Diagnostic Tests

Background The nonspecific symptoms of Valley fever, or coccidioidomycosis, hinders its proper diagnosis. This results in unnecessary health care costs and antibiotic usage. Thus, this study seeks to determine the coverage of the Valley fever diagnostic test as provided by Arizona insurance companies to increase early diagnosis rates. Methods Through scripted messaging and telephone communications, we contacted 40 health insurance companies in Arizona about their coverage of CPT 86635 (antibody diagnostic assay for Coccidioides) without prior authorization under all plan types provided in both primary and urgent care settings. If prior authorization was required, we discussed the coverage of ICD-10 codes J18.9 (pneumonia, unspecified organism), J18.1 (lobar pneumonia, unspecified organism), or L52 (erythema nodosum). Results Of the 40 health insurance companies contacted, 25 did not answer our inquiries, most requiring member-specific information to share coverage data. The remaining 15 companies covered Valley fever testing, of which 4 required prior authorization for the ICD-10 codes of interest. Of these 15 companies, 14 provided coverage in primary and urgent care settings, and 13 provided coverage for all available plans. Conclusion All payers that provided information covered Valley Fever testing. Most of the insurance companies that were unable to answer our inquiry likely cover Valley fever testing, but were unable to share information with third party inquiries. Obtaining general coverage information is difficult, which can potentially impact patient care.
