Hello everyone! I am new to the Behavioral/SA billing world and have found your forum very informative and helpful. I was wondering if it is common practice to have two different provider IDs when contracted with a payer like BCBS (one assigned for inpatient services and the other assigned for outpatient services) for a Rehab/SA Facility. I have never seen 2 provider IDs before when the NPI, TIN, taxonomy, and location are all the same. Thank you in advance for sharing your feedback.
