Trying to figure out the proper Type of Bill Code to submit on a UB-04 claim form for a Sub-Acute Detox/Residential Substance Abuse Rehab Treatment Center (Inpatient).

Currently, our Billing Dept is outsourced. They have been using Code 113.

After receiving a denial on a specific claim I contacted that insurance company. I was told that our Tax ID does not reflect a hospital setting and the first digit for claim type is incorrect and should be replaced with an 8-Specialty Facility. When I contacted the Billing Dept they stated that all those claims were resubmitted with bill type 163.

If we are not a Hospital how are they getting our claims paid as a "Hospital" setting?

Please help!
