Summary
Health First Colorado (Medicaid) now requires additional verification when contacting Provider Services - both the 8-10 digit Health First Colorado ID and NPI must be provided to access HIPAA-protected information. The policy also reinforces that Medicaid is payer of last resort and must be billed after Medicare/commercial insurance.
Action Required
Immediately: Update Provider Services call procedures to include both Health First Colorado ID (found on welcome letter, Provider Web Portal blue banner, or RA Payee ID field) and NPI when calling. Ensure third-party billing vendors have both identifiers. Continue billing Medicare/commercial insurance first before submitting claims to Health First Colorado, indicating payment/denial dates on claim forms.
