Sun Life groups routing to different boxes and tripping up your claims? We confirm the right address per group, verify before the visit, submit clean to payer ID 70408, and work every denial. See what your Sun Life AR is leaking.
Get a free AR analysisSun Life recommends a pre-estimate for any service over $500. It is encouraged, not required, and typically takes two weeks or more, so send it early on large cases. Pre-estimates can be faxed to 623-760-1876, but faxing is not a good option when x-rays are needed. Use an ADA claim form, version 2006 or later, for both claims and pre-determinations.
Sun Life accepts electronic attachments through NEA (770-441-3203) and the Vyne and DentalXChange attachment services. Label every x-ray with the patient's name, the date it was taken, the tooth numbers, and the treating dentist's name and address.
Some Sun Life plans exclude replacing a tooth that was missing before the coverage started, unless the employer elected that coverage. When a benefit is paid as an alternate benefit, Sun Life PPO dentists may bill the patient for the service actually performed, up to their Sun Life fee.
See our guides to the missing tooth clause and claim attachments.
Sun Life asks offices not to submit a claim more than once. Check status on the provider portal instead, since duplicates slow everything down.
