Note G — Revenue Recognition and Contractual Adjustments

The Company recognizes revenues when (a) the price is fixed or determinable, (b) persuasive evidence of an arrangement exists, (c) the service is performed and (d) collectability of the resulting receivable is reasonably assured.

The Company’s specialized diagnostic services are performed based on a written test requisition form or electronic equivalent, and revenues are recognized once the diagnostic services have been performed, and the results have been delivered to the ordering physician. These diagnostic services are billed to various payers, including Medicare, commercial insurance companies, other directly billed healthcare institutions such as hospitals and clinics, and individuals. The Company reports revenues from contracted payers, including Medicare, certain insurance companies and certain healthcare institutions, based on the contractual rate, or in the case of Medicare, published fee schedules. The Company reports revenues from non-contracted payers, including certain insurance companies and individuals, based on the amount expected to be collected. The difference between the amount billed and the amount estimated to be collected from non-contracted payers is recorded as an allowance to arrive at the reported net revenues. The expected revenues from non-contracted payers are based on the historical collection experience of each payer or payer group, as appropriate. The Company records revenues from patient pay tests net of a large discount and as a result recognizes minimal revenue on those tests. The Company regularly reviews its historical collection experience for non-contracted payers and adjusts its expected revenues for current and subsequent periods accordingly.

The table below shows the adjustments made to gross service revenues to arrive at net revenues (in thousands), the amount reported on our statements of operations.
