Summary
Health Net Medi-Cal has implemented a new payment process for Proposition 56 supplemental payments covering 2017-2020 services. Providers without current W-9 forms on file will now receive payments with remittance advice (RA) for physician services, developmental screening, family planning, and sensitive services, but must still submit W-9 forms for value-based payments.
Action Required
Immediately: Billing team should submit current W-9 forms to Health Net for any providers needing value-based payments by emailing with subject line 'Prop 56 W9' or faxing to 833-794-0423 with 'Prop 56 W9' and 'PROTECTED HEALTH INFORMATION' clearly marked.
