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 Massachusetts 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.
Your participation is honored nationally: if you are a Delta Dental PPO or Premier dentist with your own state's Delta company, you are treated as in network for Delta Dental of Massachusetts patients too, at the applicable fee schedule.
Delta Dental of Massachusetts claims are mailed to Milwaukee, WI, not to an address in Massachusetts. That is normal inside the Delta Dental system, where several member companies share claims processing. Sending a claim to an in-state Delta office instead of the processing address only slows it down.
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. The Delta Dental claims guide covers national rules, and our verification service does this for every patient.
