WISeR Tips & Reminders
Innovaccer & CGS are sharing the information below to help WISeR providers avoid processing delays and denials.
Prior Authorization: Primary & Secondary Codes
The scenario below uses skin substitutes (CPT codes 15271 & 15272) as an example. The guidance applies to any primary/secondary codes subject to WISeR.
Issue:
- A prior authorization request (PAR) includes CPT code 15271 (primary code) only.
- A claim for the same beneficiary/date of service includes CPT codes 15271 (primary code) and 15272 (secondary code).
Result:
- The UTN (if reported on the claim) is only valid for CPT code 15271 (primary code).
- CPT code 15272 (secondary code) suspends for prepayment medical review.
- The claim denies since Innovaccer can’t issue a decision for CPT code 15272 (secondary code) without CPT code 15271 (primary code).
Resolution:
If you plan to render and bill for multiple WISeR services, report all applicable WISeR Appendix A HCPCS codes within the same “service type” on the same PAR to receive one UTN for all services.
Claim Submission: UTNs
When you submit a PAR and receive a decision/UTN:
- Always report the UTN on the associated claim (provisional affirmation and non-affirmation).
- For services rendered in the Hospital OPD or ASC setting, report the UTN on the facility (OPD or ASC) claim only.
ADRs: myCGS Portal
The myCGS portal is available to submit documentation in response to WISeR Additional Documentation Requests (ADRs). CGS will accept the ADR response, identify the associated claim, and forward to Innovaccer.
