Summary
Beginning September 19, 2011, ForwardHealth allows providers to change or add taxonomy codes for Wisconsin Medicaid programs, enabling alignment with Medicare and other payers. Providers can report multiple taxonomy codes but must designate one as primary for identification purposes.
Action Required
By September 19, 2011: Providers who want to change or add taxonomy codes should update them via the ForwardHealth Portal demographic maintenance link or use form F-01181. Billing team must verify new codes are processed before using them on claims to avoid denials or delays. No action needed if continuing with current ForwardHealth-designated taxonomy code.
