Insurance Coverage

Medicare Our office accepts Medicare, which means that we accept the Medicare fee schedule. Medicare usually pays 80% of their allowed fee. The patient is responsible for any remaining allowed amount including their deductible. If you are covered by a secondary insurance carrier, we will submit a claim to them after Medicare has processed the claim. PPO / Private Insurances We are "out of network"/"non-participating" for most PPO or private insurances. Insurance companies typically reimburse "out of network"/"non-participating" providers at a lower rate. The patient is responsible for the difference between the billed amount and the amount that is paid by the insurance carrier. *We recommend that you check with your insurance carrier about your individual coverage. HMO's We are not a provider for any HMO and do not accept any HMO insurances. If you wish to see our physicians you will be considered a cash patient and will be responsible for the entire visit including any testing.
