We are an outpatient facility billing for IOP on UB04 claims. The counselors there do not have NPI’s so we’ve always billed with our medical directors name and billing NPI. Is this accurate? Should we bill with the LADC provider name and facility NPI or is either correct? I was taught to bill the way we have been with the directors name and claims do get processed/paid, just always questioned if this was the best or most accurate way to bill. Thanks in advance for any advice.
