When ordering a Pre‑surgical Type & Screen, all required order questions must be completed accurately. These answers drive specimen routing, collection timing, and blood bank workflow in Epic.

Beginning March 9, 2026, a new Order Validation Rules in Epic will apply to all PSA Screening orders. These rules act as hard stops and must be corrected before the order can be signed.
Applies to:
• Prostate Specific Antigen (PSA), Screening [LAB116]
Epic will stop the order if:
Diagnosis Code Is Not Z12.5. Z12.5 (Screening for Prostate Cancer) is required for all PSA Screening orders.
Patient Is <40 Years Old With BCBS Coverage. BCBS does not cover PSA Screening for this group.
Patient Is <50 Years Old With Medicare / Medicare Advantage. Medicare does not deem PSA Screening medically necessary before age 50.
Screening Was Performed Within the Past 11 Months. Annual screening limits apply; users must change the expected date if needed.
External practices will not see Epic’s validation warnings, but the draw site (phlebotomy team) will.
If a paper/EMR PSA Screening order violates any rule:
1. Phlebotomy attempts to enter the order.
2. A hard stop fires in Epic.
3. The phlebotomist cannot override the alert.
4. The order cannot be placed, even with a signed requisition.
5. Staff will:
Inform the patient
Contact the ordering provider for correction
Hold the draw until the provider updates the order
This may require the patient to return if changes can’t be made immediately.
✔ Use Z12.5 for all PSA Screening orders
✔ Confirm age + insurance coverage requirements
✔ Ensure no PSA Screening has occurred in the past 11 months
✔ Order a diagnostic PSA instead of a screening when appropriate (symptoms, abnormal findings, ongoing monitoring)

Influenza prevalence fluctuates seasonally with the onset of “flu season” typically beginning its upswing in the month of December. It is important for providers to have an awareness of influenza prevalence (in addition to other respiratory viruses) to help guide when influenza testing should be pursued.
We want to share an important update regarding the shipping timeline for requisition orders.
As part of our ongoing efforts to streamline operations and improve service delivery, Corewell Health has transitioned to a new external printing vendor for requisition materials. While this change supports long-term efficiency, it does come with a temporary adjustment in turnaround time.
Requisition shipments will now take up to 12 business days to arrive, which is a longer timeframe than previously experienced.
To help ensure your office remains fully stocked and avoids any supply interruptions, we recommend placing orders at least three weeks in advance of running out of requisitions.
We appreciate your understanding and cooperation as we adapt to this new process. If you have any questions or need support with ordering, please don’t hesitate to reach out.
Thank you for your continued partnership!
