UnitedHealthcare uses many plan- and state-specific PO boxes, so we do not list one. It asks providers to file claims, reconsiderations and appeals electronically where it can.
Provider Portal support: 866-842-3278, option 1
Live chat is also available in the UnitedHealthcare Provider Portal.
Nothing matches that. Try just the payer name or the PO box number, or read the notes below the list (they cover boxes like 650075 that payers no longer list).
Checked against each payer’s published documents on October 25, 2026. Payers move PO boxes without much notice. If the EOB, denial letter or patient ID card shows a different address, use that one.
PO Box 23456, Chattanooga, TN 37421: what goes there
PO Box 23456 in Chattanooga is HealthSpring's mailing address for new paper claims. HealthSpring is the Medicare Advantage business that used to be Cigna Medicare, so you will still see this box on older "Cigna HealthSpring" cards and letters.

HealthSpring appeal boxes in Dallas, TX 75265
HealthSpring uses several PO boxes in Dallas with the same ZIP, 75265. They look alike, so check the box number against the type of request:
| PO Box | Use it for | Fax |
|---|---|---|
| 650065 | Postservice appeals and medical necessity disputes from participating providers. Due within 65 days of the decision. | 855-699-8985 |
| 650059 | Standard Part C appeals, appeals from non-contracted providers (with a signed Waiver of Liability), and appeals of denied authorizations. | 855-350-8671 |
| 650058 | Expedited medical appeals. | 855-350-8672 |
| 650040 | Fast track appeals (Quality Improvement Organization). | 855-594-4432 |
PO Box 650075, Dallas, TX 75265: people search for this box, but we could not find it in HealthSpring's current provider manuals or on its appeals pages. If a letter tells you to use it, call HealthSpring at 800-511-6943 before you mail, or fax the matching number above so you have a dated receipt.
A note on older PDFs: one HealthSpring appeals handout lists Chattanooga boxes instead (PO Box 188085 for participating providers, PO Box 188081 for non-contracted providers, ZIP 37422). The October 2026 manual and HealthSpring's appeals web page both list the Dallas boxes. The fax numbers are the same in both, so faxing is the safe choice when you are unsure.

How to pick the right address
Most lost appeals are not bad appeals. They went to the claims box instead of the appeals box, or to an address the payer retired. Four checks prevent that:
- Read the denial letter or EOB first. The address printed there was chosen for that plan and that claim. It beats any list, including this one.
- Match the request type. A reconsideration (the payment amount is wrong) and an appeal (the payer said the service should not be paid) often go to different boxes. HealthSpring is a good example: 1004 in Nashville for reconsiderations, 650065 in Dallas for postservice appeals.
- Check network status. HealthSpring sends non-contracted providers to different appeal addresses and asks for a signed Waiver of Liability.
- Fax or file online when you can. A fax confirmation or portal receipt is proof of the date it arrived, and arrival is what counts against the deadline.
Deadlines matter as much as addresses. See the HealthSpring timely filing guide, the Aetna guide, the Cigna guide and the UnitedHealthcare guide, or count the days with the timely filing calculator.
