Credentialing isn’t one task — it’s a 90-to-120-day operational program with four distinct phases, multiple payer-side dependencies, and a long list of places it can stall. This page lays out how PPS actually runs a credentialing engagement, what we deliver in each phase, and what the realistic timeline looks like for each step.
The four phases
Phase 1 — Intake and document audit. We pull every credentialing document on file, verify the CAQH profile is current and attested, audit against payer requirements, and flag gaps. Common gaps: expired malpractice COI, lapsed CAQH attestation, missing peer references, stale board certification, hospital privileges letter older than 6 months. Phase 1 usually takes 1 to 2 weeks depending on how quickly the provider can produce missing documents.
Phase 2 — Parallel payer submission. Applications go out to every payer concurrently. We don’t sequence. This is the largest delta between us and in-house or billing-company credentialing teams. Phase 2 takes 2-3 weeks of submission work but the calendar runs into Phase 3 quickly.
Phase 3 — Follow-up, escalation, and document response. Most of the calendar time. Payers ask for additional documentation. Applications stall. Provider relations teams change. We follow up at week 4, escalate at week 8, and run document responses same-day. Phase 3 runs weeks 4 through 16.
Phase 4 — Effective-date confirmation. Each payer comes back with an effective date. Some are retroactive to the application date (which matters for billing). Some are prospective. We confirm in writing and hand off to your billing team. Phase 4 happens rolling as payers approve.
Where engagements actually stall
In our book of business, the most common stalls are:
- CAQH attestation lapsed mid-application — payer pulls the profile, sees an expired attestation, pauses review. Preventable with CAQH Credentialing Services.
- Hospital privileges letter expired — most payers want a hospital privileges letter dated within 6 months. If it expires mid-review, the application restarts.
- Malpractice claim history disclosure incomplete — providers genuinely forget closed claims from 8 years ago.
- State license verification not received by the payer — license verification is supposed to flow automatically; it often doesn’t.
We track all of these proactively so they don’t happen on our files.
Process sub-pages
Two operational tracks worth reading in detail:
- Insurance Credentialing Process — Established Groups — the workflow for adding providers to an existing group’s payer panels.
- New Practice Enrollment & Contracting Process — the workflow for a brand-new practice with no existing payer relationships.
