Delta Dental's rule is that a claim goes to the Delta company that provides the patient's coverage, not to the Delta company where your office is. A patient who works for a company headquartered elsewhere can carry a Delta Dental of Tennessee card while living in another state, and the reverse is just as common. Read the company name on the ID card, or look the patient up under My Patients in the National Dentist Dashboard, before you submit.

Most Delta Dental claims that come back unpaid were sent to the wrong member company, sent under the wrong payer ID, or hit a frequency limit nobody checked. Verify the company, plan type (PPO, Premier, DHMO or individual) and frequencies before the visit.
