I am wondering if a provider does a procedure like a Tenotomy (23405-52 or 27006-52) in the office, if he can charge the patient for supplies for the procedure. By not doing this in a surgical center or hospital he must supply the supplies himself and will get paid a reduced fee because of this. Are these billable to the insurance company (under what code?) or can he charge patient outright and not bill the insurance for the supplies?
