DC Medicaid Wellpoint to AmeriHealth Transition: August 2026

Use the service date to identify the responsible plan

Wellpoint remained responsible for covered services through July 31 at 11:59 p.m. AmeriHealth became the automatic assignment on August 1 for affected members. Record the member, eligibility response, assigned MCO, service date and time, location, authorization, claim route, and checked date. A prior Wellpoint card, portal row, or appointment record cannot establish the current payer after the transition.

Preserve the member's plan-choice period

Affected members may choose MedStar Family Choice through January 31, 2027 under the transmittal. Separate automatic assignment from a later member election and effective date. Give families the official choice route and accessible assistance without steering them toward a plan for the provider's convenience. Update payer configuration only from current eligibility or written program evidence.

Honor active referrals and prior authorizations

DHCF says referrals and prior authorizations issued before August 1 remain valid through October 31 regardless of the provider's contract status. Save the original issuer, member, service, provider, code or service description, units, dates, conditions, reference number, and transition citation. Confirm how the receiving plan wants the evidence attached or referenced. Do not replace the original authorization number with a locally invented identifier.

Create an authorization handoff record for each protected episode. Link the Wellpoint artifact, AmeriHealth member identifier, current provider and location, remaining approved amount, scheduled services, attachment route, receipt, transition end date, and next request owner. Keep the original evidence unchanged and record any AmeriHealth reference as an additional identifier. If the two plans describe the protected amount differently, hold the disputed schedule or claim configuration for written resolution.

Track the separate 60-day ongoing-treatment protection

The transmittal also says AmeriHealth should honor ongoing authorized treatment for up to 60 days or through the last day of the transition period. Record the member-specific start, authorized care, transition date, applicable end condition, written plan confirmation, and next authorization action. Use the more specific controlling instruction when the 60-day and October 31 descriptions appear to produce different dates.

Keep appointments while validating safe release

DHCF instructs providers not to cancel appointments solely because of the transition. Before each service, verify active eligibility, current MCO, authorization protection, qualified staff, safe and accessible setting, required clinical information, and a documented claim route. If payer evidence remains unresolved, escalate promptly and communicate the exact administrative state to the family. Emergency duties follow their own route.

Use accessible transition communication. Explain the automatic assignment, member choice period, current service plan, unresolved payer questions, and next contact in the person's preferred language and format. Preserve interpreter and AAC access, required consent and assent processes, and the person's own plan preference. Avoid steering, promising a covered start, or presenting a credentialing problem as a clinical decision.

Track claims across the payer boundary

Route each claim by service date and current program instruction. Store the original claim, payer acknowledgment, rejection or adjudication result, remittance, deposit, correction, and final disposition. A Wellpoint claim for a July service, an AmeriHealth claim for an August service, and a corrected claim after the transition belong to separate episodes even when the authorization spans all three.

Prevent duplicate submissions during uncertainty. If a claim reached the wrong payer, identify the prescribed correction or transfer route and preserve both transmissions. Report pre-adjudication rejects, adjudicated denials, and unpaid approved claims separately so the team can fix the correct layer.

Recheck member choice without overwriting history

Set dated eligibility rechecks through the January 31, 2027 choice period and before every affected service. When a member elects MedStar, create a new payer configuration with its effective date, authorization treatment, provider status, and claim route. Retain the prior automatic assignment and dates for historical claims and audits. The latest plan should never be applied retroactively without controlling evidence.

Separate credentialing from continuity protection

The transmittal provides AmeriHealth and MedStar credentialing contacts. A transition protection can permit covered continuity without proving network participation, contracting, roster acceptance, effective date, clean-claim status, or payment. Track credentialing and contracting as separate provider configurations. Preserve any out-of-network or single-case instruction that applies to the member and period.

A fictional managed-care transition cohort

Iris locks 31 Wellpoint episodes with services scheduled between July 20 and October 31. Twenty-six identify the correct service-date payer, current eligibility, protected referral or authorization, provider route, family update, claim owner, and recheck date. Three rows still use Wellpoint after July 31, one lacks the original authorization, and one omits a later MedStar election. Route readiness is 26 of 31, or 83.9%.

Use a transition release checklist

Verify member identity, current eligibility, July 31 or August 1 service-date boundary, automatic assignment, later plan choice, active referral, prior authorization, protected period, ongoing-treatment rule, current provider status, claim route, credentialing work, family communication, appointment state, receipt, remittance, correction route, and next recheck. Monitor the current DC managed-care plans page for later changes.
