CHAMPVA fax number for applications, documents and approvals

The CHAMPVA fax number for applications and supporting documents is 303-331-7809 - VA lists it for the Application for CHAMPVA Benefits (VA Form 10-10d), for documents VA asks for after you apply, and for updates like a school enrollment letter. Prior approval for inpatient mental health care and alcohol or substance use care is a separate number, 303-331-7807, and CHAMPVA claims are not faxed at all: VA takes them online or by mail.

This guide lists the CHAMPVA fax numbers VA publishes itself, what goes to each one, and how to fax from your phone with HonestFax if you don't have a fax machine.

CHAMPVA fax numbers, by document

The 303-331-7809 number appears on three va.gov pages: "CHAMPVA Benefits" (how to apply), "What to do after applying for CHAMPVA benefits" and "CHAMPVA care" (updating your information). The approval number is on the "CHAMPVA care" page.

Faxing a CHAMPVA application (VA Form 10-10d)

VA accepts the CHAMPVA application online, by mail or by fax. To fax it:

1. Download and fill out VA Form 10-10d from va.gov.
2. Gather the supporting documents that apply to you. If you have other health insurance, including Medicare, that means a copy of the front and back of the card (and the Medicare Part D card if you have one).
3. Fax the application and the documents together to 303-331-7809.

VA says it typically reviews applications within 5 business days, and the decision comes by mail. If you applied while signed in to VA.gov, you can check the status online.

CHAMPVA prior authorization fax number

Most CHAMPVA care doesn't need approval first. VA lists four kinds that do: inpatient mental health care, care for alcohol or substance use disorders, dental care in the limited cases CHAMPVA covers it, and organ transplants.

For mental health, alcohol use or substance use care, VA asks your provider to request the approval by calling 833-930-0816, faxing 303-331-7807, or emailing VHAHAC.PreauthorizationFM@va.gov. If you are the patient, pass this number to the provider's office rather than faxing it yourself.

Can you fax a CHAMPVA claim?

No. VA's "How to file a CHAMPVA claim" page lists two ways: online, or by mail with VA Form 10-7959A to VHA Office of Integrated Veteran Care, CHAMPVA Claims, PO Box 500, Spring City, PA 19475. You must file within 1 year of the care (or of leaving the hospital), and VA says processing takes about 90 days. Don't fax a claim to the application number - it is the wrong office for it.

Other health insurance updates (VA Form 10-7959c with copies of your cards) are also listed as online or by mail only.

Before you fax: the one-sided rule

VA says it can only scan one side of each document. If something is double-sided - an insurance card, a two-sided letter - fax each side as its own page. With a phone this is easy: scan the front, then the back, as two pages.

Two more things from VA's pages:

• Send each document once. VA warns that sending the same document again can delay processing.
• Send only what was asked for. After you apply, extra documents VA didn't request can slow the review.

Put the patient's full name, a phone number and what you are sending on a cover page. Our cover sheet guide shows a clean layout, and how to scan documents for a fax keeps signatures and small print readable.

How to fax CHAMPVA documents from your iPhone

You don't need a fax machine. With HonestFax:

1. Install HonestFax and open the New Fax tab. No account, no email address.
2. Add a cover page with your name, phone number and a short note ("CHAMPVA application, 6 pages").
3. Scan each page with the camera - front and back as separate pages - or add a PDF from Files (see how to fax a PDF from iPhone).
4. Choose United States and enter 303-331-7809 (or give 303-331-7807 to your provider for approvals).
5. Check the price on screen and send. Each page is 1 credit. If the line is busy, the app retries for about 30 minutes, and if the fax still fails, the credits come back automatically.
6. When it says Delivered, VA's fax line accepted every page. Keep that record with the date and page count.

Faxing vs. applying online

If you have a VA.gov account, applying online lets you upload the documents with the application and check the status later. Faxing makes sense when the pages are on paper, when you don't want to set up an account, or when a VA letter asked you to fax. For other VA benefits - disability compensation, pension, medical records - the numbers are different: see our VA fax number guide. If you also have Medicare, the Medicare fax number guide covers which Medicare tasks take a fax.
