I do not understand how Suboxone visits in your area are mostly self-pay. Regardless of where you are in the country, most PCPs will accept a wide variety of insurances. Providers cannot simply cherry-pick Suboxone patients and demand cash as it would violate their insurance contracts. An exception to this is if the patient is on an insurance plan that is not offered by the practice or if the patient does not have insurance. These exceptions, however, do not mean the practice is self-pay. It just means the the patient is paying out-of-pocket because of lack of insurance. The alternative scenario I can think of is your area has mostly niche Psych/addiction cash practices that are self-pay because they operate on an out-of-network basis. Either way, your claim does not appear to be representative of the rest of the United States. If you believe it is, I would like to hear of any evidence you have supporting the claim.
a lot of insurance plans(I dont know what percentage...I thought most?) pay for suboxone as a medication but will not pay for suboxone visits since many insurance plans do not pay for outpt addiction medicine services. Or they do and they come with large copays that wont be met based just on office visits within addiction medicine.
