How to check Oak Street Health eligibility

A portal or phone check takes a front-desk staffer 10–15 minutes per patient. Oak Street Health has no eligibility API — so instead of your staff doing that, our screen agent runs the portal check for you, on your schedule.

Three ways to verify Oak Street Health coverage

  1. Payer portal — free, but one patient at a time and 10–15 minutes each with logins.
  2. Phone (IVR) — hold times vary; no written record for the chart.
The third way

Automated portal check

Medman's screen agent signs in to the Oak Street Health portal with your practice's own login and checks your whole schedule before the day starts. Results are waiting at check-in instead of being looked up one patient at a time.

Setup required: we connect your portal login during onboarding.

Questions

Frequently asked questions

What is the payer ID for Oak Street Health?

Oak Street Health uses payer ID OAKST. It also appears as 8725 in some systems.

Does Oak Street Health support real-time eligibility verification?

Oak Street Health has no eligibility API, so there is no 270/271 transaction to send. Checks still run automatically: our screen agent performs the portal check for you on your schedule, rather than a staff member doing it per patient. Setup is required. Claims can be submitted electronically.

How long does a Oak Street Health eligibility check take?

A portal check takes 10–15 minutes of staff time per patient. A screen agent runs the same check without occupying anyone — scheduled ahead of the day's appointments, so results are waiting rather than being fetched one patient at a time.
