Daily portal workflows for treatment centers

Eligibility and VOB

Start with active eligibility, network status, cost-share, and whether the levels of care listed on the Centene / WellCare profile are covered for the member: Detoxification · Residential Treatment (state-dependent) · Partial Hospitalization (PHP) · Intensive Outpatient (IOP) · Outpatient Treatment · Crisis Stabilization · Medication-Assisted Treatment (MAT).

Prior authorization

Use the profile criteria as the intake checklist before submitting an authorization request: State-Specific Medicaid Guidelines · ASAM Criteria (for SUD level of care placement in most states). Keep the clinical packet aligned with the portal's required fields.

Claim status and follow-up

After claim submission, use the portal to tie each follow-up back to the member eligibility response, authorization record, rendering or facility identifiers, and the payer routing confirmed during VOB.

Credentialing updates

Keep portal access aligned with credentialing context from the profile: CAQH ProView · 90-120 days (varies by state subsidiary). New locations, tax IDs, and roster changes should not wait until a claim denies.

What to verify before admission

Confirm active coverage, network status, plan type, member responsibility, and the specific payer route attached to the member's plan.
Match the requested level of care against the profile's covered levels of care: Detoxification · Residential Treatment (state-dependent) · Partial Hospitalization (PHP) · Intensive Outpatient (IOP) · Outpatient Treatment · Crisis Stabilization · Medication-Assisted Treatment (MAT).
Prepare clinical documentation against the listed medical necessity criteria: State-Specific Medicaid Guidelines · ASAM Criteria (for SUD level of care placement in most states).
Check whether the member's state, product, or network arrangement changes portal access, payer routing, or authorization requirements.
Use the Centene / WellCare insurance profile as the source page for credentialing, coverage, and payer-specific operating context.

Authorization and documentation notes

Why is working with Centene confusing due to its subsidiary structure?

Each subsidiary operates under its state Medicaid contract with distinct requirements and processes.

Providers must confirm which Centene product the member is enrolled in to apply the correct billing and authorization processes.

Claims, denials, and follow-up

Before claim submission, confirm the payer route, authorization number, billed level of care, rendering and facility identifiers, date range, and whether another payer is primary. When a claim stalls, work backward from the portal record to the VOB, authorization, and documentation packet.
