Not possible. An hmo gives a dentist such a little fee that it does not even cover the cost of the procedure, the materials, and sterilization of the instruments in most instances. The way a dentist is paid in a hmo network is by the number of people who sign up. The amount you are being charged is only available to you due to other people who signed up and did not come in for dental care.
HMO. Ask your hmo for a list of preferred contracted providers.
Need to contact. Your insurer with a list of providers that accept your insurance. That would be the best resource for you.
Ask HMO for list. Hmo (dmo for dentistry) should have list of providers. Ask your insurance company for list. There may be a copay. Insurance was supposed to be hedge against catastrophic loss, not cradle-to-grave nanny state. If practitioner agrees to accept reduced fee plan they must reduce cost of doing business, which means compromise in level of care.
