ROC Masterminds Recap: Inside Three Resolved PPR Audits

This month’s Masterminds session delivered a focused deep dive into three recently resolved Prepayment Review (PPR) audits out of California. Thank you to our Hansei leaders — Erin Burke, Alexxis Ames, and Jenna Joneikis — for walking the group through these case studies.

If you’ve missed the last few months of our ROC Masterminds meetings, here’s a recap on PPRs.

A Prepayment Review (PPR) is when a payer flags a provider and holds every claim before payment—scrutinizing documentation and validating medical necessity before releasing payment. For behavioral health providers, that means delayed cash flow, added admin burden, and denials that can snowball into a full audit. And PPR doesn’t discriminate — size, reputation, and years in operation don’t make a facility immune.

Three Audits, Three Different Fights

Anthem Blue Cross of California — This case centered on PHP/IOP and routine outpatient services billed together, which triggered administrative findings. The provider successfully challenged those findings through appeal and regulatory intervention. Payment release and system updates are still catching up, but the underlying issue was resolved.

A tax ID denial case — A payer system error caused claims to be automatically denied before they ever reached the Special Investigations Unit (SIU) for review. Once appealed, the facility saw the PPR lifted and payments resumed.

California Blue Shield — The most complex of the three, involving alleged billing irregularities, eligibility questions, and disputed diagnoses. After SIU coordination and an on-site visit, the facility came off PPR effective August 6 and received a significant backlog payment. The tradeoff: the facility lost its in-network status.

Together, these cases underscore a theme the group keeps coming back to — PPR outcomes hinge on documentation discipline, timely appeals, and knowing exactly which lever (SIU escalation, regulatory intervention, on-site review) to pull for a given denial pattern.

Payer Issues Still in Motion

Beyond the case studies, the group flagged a few live payer situations to watch:

Anthem post-payment review — Still open, with payments continuing in the meantime. A completion letter, education letter, or a move to prepayment review are all still on the table. There’s also an unresolved contracted-rate misprocessing issue dating back to June 6 that Anthem has yet to fully correct.
Texas reimbursement delays — Tied to the Blue Cross Blue Shield/Magellan separation, driven by volume spikes and system configuration problems. Reprocessing has largely caught up.
Optum’s ASAM code rollout — Created contract-to-system mismatches, leading to denied claims across multiple states, including Texas and New Mexico. Resolution is still in progress.

What’s Next

The group’s takeaway: keep a close eye on denial and EOB patterns, and don’t let payer accountability slide just because a claim eventually gets paid. The three case studies discussed will soon be turned into a shareable resource for the wider ROC community.
