What You Can Fax to American Specialty Diagnostics

  • A specimen-collection or send-out instruction for a referred test
  • A standing or recurring lab order (for example, monthly INR or metabolic panels)
  • The study report going back to the referring provider
  • A request to release lab results or a report back to the ordering provider
  • A prior-authorization approval for a genetic, molecular, or otherwise specialized test
Tip: Mark all pages with the patient identifiers (name, date of birth, record number) that American Specialty Diagnostics needs to reconnect a split order. Direct the cover sheet to the scheduling and test-ordering office or the office handling the request, with a callback number for questions. Group the pages into a single fax and hold onto the confirmation in case you need to prove it arrived.

Faxing a prior authorization to American Specialty Diagnostics

A payer approval for a test at American Specialty Diagnostics is routed to the billing office, not the laboratory team. Many payers require the clinical indication and, for genetic testing, evidence that criteria are met. Address the cover sheet to the billing and insurance office so the approval is filed against the order.

Where a new order goes at American Specialty Diagnostics

Faxing a requisition to American Specialty Diagnostics means reaching the client services office that logs the order into the lab. The diagnosis code is what lets the office confirm coverage and, for specialized assays, start prior authorization. Send the order and the supporting notes as one fax so nothing arrives split.

Faxing to American Specialty Diagnostics — FAQ

The machines accept faxes around the clock; staff processing depends on the office. The offices that handle orders and records keep standard weekday hours. Send routine requests early in the day for same-day handling; stat orders are worked during testing hours. Flag anything time-sensitive on the cover sheet so it is not treated as routine.

It can be, with the right service. Faxing itself is accepted for PHI; the transport is what has to be secure. Send FAX Mail encrypts pages in transit and includes HIPAA starting at $39.99/month — safer for PHI headed to American Specialty Diagnostics than a public machine. Choose the secure channel first, then confirm the number for American Specialty Diagnostics.

Ask the specific American Specialty Diagnostics office for its working fax before you send. Check American Specialty Diagnostics's client-services or medical-records page, then verify the line by phone. A quick check beats faxing PHI to a number that has moved. The office that receives the fax is the authority on its own number.

Submit a signed release-of-information authorization to the medical records office at American Specialty Diagnostics. Ask American Specialty Diagnostics where the signed release should go. A complete request — identifiers, dates, and results wanted — moves fastest. After review, the records go to you or whoever the patient designated.

Send the order to scheduling and the report request to records. Get the working scheduling fax from American Specialty Diagnostics directly. Include the study requested, the clinical indication, and the patient identifiers. A brief call ahead helps staff watch for a time-sensitive fax. It is a small step that saves a follow-up call later.
