Medicare Advantage, also called Medicare Part C, is not the same as traditional Medicare. Each Advantage plan is run by a private carrier such as Humana, UnitedHealthcare, Aetna, or a Blue Cross affiliate, and each one credentials and contracts providers on its own terms, through its own portal, on its own timeline. Being enrolled in traditional Medicare through PECOS does not put you in any Advantage network. You still have to be credentialed and contracted with every carrier whose members you intend to treat in-network.
White Glove manages the full path for each carrier you choose: a complete and attested CAQH profile, the credentialing application and primary-source verification, and a fully executed participation agreement with the right effective date. We run the carrier portals, chase the network-management contacts, and keep every application moving so you stop guessing where your files stand and start seeing Advantage members.
Built on your Medicare base
Most Advantage carriers require an active Medicare PTAN before they will network you. We confirm your traditional Medicare enrollment is in order, then build the Part C work on top of it.
CAQH done right
Carriers pull credentialing data from CAQH ProView. We complete it, attest it, re-attest on schedule, and authorize each carrier so your file is never stuck waiting on a stale profile.
Credentialing and contracting both
Passing credentialing does not let you bill. We push past committee approval to a signed, loaded participation agreement and a confirmed effective date for each carrier.
Every carrier, one team
Humana, UnitedHealthcare, Aetna, Cigna, Centene, and Blue Cross Advantage plans each work differently. We track all of them in parallel and report status in one place.
How Medicare Advantage enrollment differs from traditional Medicare
Traditional Medicare is a single federal program processed through PECOS and a Medicare Administrative Contractor. Medicare Advantage is dozens of separate private contracts. The carrier administers the benefit, builds its own network, and decides who is in it. There is no central system that grants you Advantage participation across the board.
That distinction drives everything. You do not enroll in Medicare Advantage once. You credential and contract with each carrier, often plan by plan and product by product, and your traditional Medicare PTAN is usually a prerequisite the carrier verifies before it will move forward. We treat the two as connected but separate workstreams so neither one stalls the other.
Credentialing versus contracting — and why both matter
Joining a Medicare Advantage network is two distinct steps that buyers routinely conflate. Credentialing is the carrier verifying your license, education, board status, malpractice history, and sanctions through primary-source verification, then taking your file to a credentialing committee. Contracting is the carrier offering and executing a participation agreement that sets your in-network status, fee schedule, and effective date.
You can pass credentialing and still not be able to bill in-network until the contract is signed and loaded into the carrier's claims system. We do not consider a carrier done until the agreement is countersigned, the effective date is confirmed in writing, and your participation shows correctly in the carrier directory.
Working across carriers and their portals
Each Advantage carrier runs its own front door. Optum and the UnitedHealthcare provider portal handle UnitedHealthcare Advantage. Availity is the shared gateway for many Aetna, Cigna, and Blue Cross plans. Humana routes through its own provider tools. The data each one wants overlaps but never matches exactly, and a field that is optional at one carrier blocks the file at another.
We maintain a master record of your credentials and translate it into each carrier's format, submit through the correct portal, and own the follow-up with each network-management contact. You sign and attest where required; we handle the portals, the uploads, and the status chasing.
Why Medicare Advantage applications stall
The failure modes are different from traditional Medicare and tend to cluster in a few places:
- An inactive or unverified Medicare PTAN that the carrier checks before credentialing and finds missing.
- A CAQH profile that is incomplete, unattested, or not authorized for that specific carrier to access.
- Network status closed for your specialty in a service area, which is a business decision the carrier must agree to waive.
- The handoff gap where credentialing approves but contracting never gets initiated, so nothing happens for weeks.
- Directory and roster mismatches where your name, address, or TIN does not match across CAQH, the contract, and the carrier directory.
Realistic Medicare Advantage timelines
A clean Advantage credentialing-and-contracting cycle typically runs 60 to 120 days per carrier, and it varies widely. Credentialing committees often meet on a monthly cadence, so a file that misses a committee date waits for the next one. Contracting can add weeks after approval, especially when fee-schedule terms or a roster load are involved.
Because each carrier is independent, the smart move is to run them in parallel and start as early as possible. We submit your strongest carriers first, work the rest concurrently, and keep effective dates aligned to your start so you are not seeing Advantage members out of network while a contract sits unsigned.
Groups, facilities, and roster management
For group practices and facilities, Medicare Advantage participation is a roster exercise. Each provider must be individually credentialed and then linked to the group's contract and every billing TIN and location. Carriers manage this through roster files and delegated rosters, and a single mismatch can leave a provider credentialed but invisible in the directory and denied at the claim.
We map your provider roster to each carrier contract, submit adds and changes through the right process, and confirm each provider shows as participating at each location before claims go out. When a provider leaves, we handle terminations so an inactive link does not create directory or audit problems.
We handle the paperwork. You see patients.
Application assembly, primary source verification, payer follow-ups, and status tracking — concierge credentialing with nothing left to chase.
View pricingHow It Works
Discovery and Medicare base check
We confirm your traditional Medicare enrollment and PTAN are active, identify the Advantage carriers and products that fit your patient mix, and gather your credentialing documents.
CAQH build and attestation
We complete or update your CAQH ProView profile, attest it, and authorize each target carrier to access it so credentialing can begin without delay.
Carrier submissions in parallel
We submit credentialing through each carrier portal at once, formatting your data to each carrier's requirements and tracking every file in one place.
Credentialing committee follow-through
We respond to verification requests, keep your file ahead of committee dates, and push for approval rather than waiting passively in a queue.
Contracting and effective date
We move each approved file straight into contracting, review the participation agreement, and confirm the effective date in writing before we call a carrier done.
Directory confirmation and roster upkeep
We verify you appear correctly in each carrier directory, keep roster links current for groups, and re-attest CAQH on schedule so participation never lapses.
Medicare Advantage — Frequently Asked Questions
Is Medicare Advantage credentialing the same as enrolling in Medicare?
+
No. Traditional Medicare is a single federal enrollment through PECOS. Medicare Advantage is a set of private contracts with carriers like Humana, UnitedHealthcare, and Aetna, and each one credentials and contracts you separately. Being enrolled in traditional Medicare does not put you in any Advantage network, though most carriers require your active Medicare PTAN before they will network you.
How do I get on a Medicare Advantage panel or network?
+
You complete the carrier's credentialing application, pass primary-source verification and a credentialing committee, then sign a participation agreement that sets your in-network status and effective date. Most carriers pull your data from CAQH ProView. We manage every step per carrier, from CAQH through a confirmed, loaded contract.
How long does Medicare Advantage enrollment take?
+
A clean cycle typically runs 60 to 120 days per carrier, but it depends on committee schedules and contracting. Missing a monthly committee date pushes the file to the next meeting, and contracting can add weeks after approval. Running carriers in parallel and starting early is the best way to compress the calendar, which is how we work your file.
Do I need to be in traditional Medicare before joining an Advantage plan?
+
In most cases yes. Carriers commonly verify an active Medicare PTAN as a prerequisite for Advantage credentialing. If your traditional Medicare enrollment is incomplete or inactive, the Advantage file stalls. We confirm your Medicare base is in order before, or alongside, the Part C work so it does not become a hidden blocker.
Why is my Medicare Advantage application stuck?
+
The usual causes are an inactive or unverified Medicare PTAN, an incomplete or unattested CAQH profile, a closed network for your specialty in that area, or the gap where credentialing approves but contracting never gets started. We reconcile your data up front, authorize each carrier on CAQH, and drive the credentialing-to-contracting handoff so files do not sit.
Do I have to credential with every Medicare Advantage carrier separately?
+
Yes. Each carrier runs its own network, portal, and committee, so there is no single application that gets you into all Advantage plans. We maintain one master record of your credentials and submit it to each carrier in the format they require, tracking all of them at once so the work does not multiply your effort.
What is the difference between credentialing and contracting for Medicare Advantage?
+
Credentialing is the carrier verifying your qualifications and approving you through a committee. Contracting is the executed participation agreement that makes you in-network and sets your effective date. You can be credentialed and still unable to bill in-network until the contract is signed and loaded. We do not stop until both are complete and confirmed.
Can you enroll an entire group practice in Medicare Advantage plans?
+
Yes. We credential each provider, link them to the group contract and every billing TIN and location through each carrier's roster process, and confirm each provider appears correctly in the carrier directory before claims go out. We also handle terminations when a provider leaves so your roster stays clean and accurate.
