Carelon fax number for prior authorization (by program)

The Carelon fax number for prior authorization depends on which Carelon program handles the request: for pharmacy prior authorization, CarelonRx publishes fax 844-521-6940 (phone 833-293-0659). Medical benefits requests (imaging, cardiology, sleep and similar) are meant to go through the Carelon ProviderPortal or by phone, and behavioral health uses the number of the member's health plan - and if you need to send the pages from your phone, a fax app like HonestFax does it without a fax machine.

Carelon runs several businesses for health plans, so there is no single "Carelon fax number". Below is which number goes with which request, what each source says about it, and how to fax the form from an iPhone so it arrives readable.

Fax a Carelon prior authorization from your iPhone with HonestFax

If the request is a paper form, you can fax it from your phone. HonestFax scans the pages with the camera, shows the price before you scan, and marks the fax Delivered once Carelon's line accepts every page.

1. Fill in and sign the prior authorization form from the health plan or Carelon. If you have it as a PDF, attach the file instead of printing it - see how to fax a PDF from your iPhone.
2. Download HonestFax from the App Store and tap to add pages. Use the scanner rather than a regular photo, so small print and checkboxes stay readable. Tips in how to scan documents for a fax.
3. Add a cover page: who it's for (for example "CarelonRx - Prior Authorization"), your practice name and callback number, and the page count. What to put on a fax cover sheet has the full list.
4. Enter the fax number exactly as the table or your form shows it, check it once more, and send.
5. Wait for Delivered, and keep the copy of what was sent. That is your proof of the time and the page count if Carelon says it never arrived.

A fax of up to 3 pages is $2.99 with HonestFax and your first page is on us; larger packs are cheaper per page. If the line is busy, the app retries on its own, and if the fax can't get through after every retry, the credits come back automatically.

CarelonRx: pharmacy prior authorization fax

CarelonRx is Carelon's pharmacy benefit manager. Its contact page lists one route for providers: for prior authorization, prescription exceptions and utilization management, call 833-293-0659 or fax 844-521-6940. Home delivery has its own numbers (833-396-0309, fax 833-389-4172).

One exception is printed at the top of the same page: if the member's medical and pharmacy benefits are covered through Anthem Blue Cross and Blue Shield or Anthem Blue Cross, CarelonRx asks you to use the number on the back of the member ID card or the health plan's website instead. So check the card first.

Carelon medical benefits management: imaging, cardiology, sleep and more

Carelon Medical Benefits Management reviews requests for programs such as radiology, cardiology, sleep, musculoskeletal and genetic testing on behalf of health plans. Here the fax is not the way to start a request. As one example, Blue Cross and Blue Shield of Texas tells providers to submit through the Carelon ProviderPortal (available around the clock) or by phone at 1-800-859-5299, and lists fax 1-800-610-0050 with a note: the fax option is only for physicians or professional providers sending clinical information for existing requests.

The same page asks providers not to submit medical records unless Carelon requests them. Other health plans that work with Carelon publish their own pages and forms, so use the number printed on your plan's form - it beats any list, including this one.

Carelon behavioral health

Carelon Behavioral Health (formerly Beacon) handles mental health and substance use benefits for many plans, and the authorization route depends on the plan. Its provider contact page says to call the number on the member's card for questions about authorization or benefits. The fax number on that page, 866-612-7795, is for practitioner record updates and supporting documents such as malpractice insurance sheets - not for authorization requests.

Before you fax: three quick checks

• The member ID card and the form win. Carelon works through many health plans, and the plan's own form or card lists the right number for that member.
• Send only what the form asks for. Extra records slow things down, and at least one plan asks you not to send them unless requested.
• Keep the Delivered record. A delivered fax means Carelon's machine accepted every page. The review itself comes later - how to confirm a fax was received explains what the status does and doesn't prove.
