Completed OPAF applications and requested documents; the forms also permit written patient-authorization withdrawal to this address. Not commercial copay reimbursement or patient payments.

Use the June 2026 product-specific form; filenames still contain 2025. The foundation sets eligibility and Otsuka America Pharmaceutical, Inc. has no role in its decisions. REXULTI and MAINTENA forms show 8 a.m.-6 p.m. on early pages and 8 a.m.-8 p.m. on later pages; confirm service hours. Only these three reviewed medicines are mapped here.

Call preparation · editorial guide

Make the call count.

Find billing teams, financial-assistance programs and payment correspondence addresses. A bill-payment address is not a claims, records or specimen destination.

Have ready in your secure workspace

  • Lab or provider bill and relevant insurance explanation, kept privately
  • Existing billing or assistance reference
  • Authorized representative information if required

Questions to resolve

  • Is this a bill, insurance explanation or assistance application?
  • Which department reviews the balance or assistance request?
  • What written confirmation will document the next step?

This is a general administrative checklist, not payer policy or advice about a particular patient. Confirm the current plan instructions.
