Our Network
Check your doctor. Find a new one. All 50 states.
Whether you're thinking about joining Solo and want to confirm your doctor is in-network first, or you're a member looking for care near you, this is the place. Solo runs on the Multiplan PHCS (now Claritev) network — one of the largest nationwide PPO networks — plus the flexibility of an open network for providers who aren't listed. No referrals, ever.
Not a member yet? This is the best first step before you join — most people find their current doctors already in the network. Here's how to check:
- Visit the Multiplan Provider Search Tool and select "PHCS Practitioner & Ancillary" as your network.
- Search by your doctor's name to confirm they participate — or search by specialty and ZIP code to find new providers near you.
- Save the provider's details for your records, and call the office to confirm they still participate — network listings can occasionally lag behind reality, so a quick call before your first visit is worth it.
Why in-network matters: when you stay in-network, your care is priced at negotiated rates — which means the most predictable costs and no billing surprises.
Solo is an open-network plan. If your preferred provider isn't listed with Multiplan PHCS, you can very likely still see them:
- They bill Vault Admin Services directly. Most providers will — give the office your ID card and have them call the number on the back to coordinate payment.
- Out-of-network claims are priced fairly. They're processed under Reference-Based Pricing (RBP), which reprices each claim against objective benchmarks like Medicare rates and regional cost data. You may owe more than in-network, so confirm status before care when you can.
- You have backup on billing. Our Fairos/OccuNet team assists with provider negotiations and steps in if you ever receive an unexpected balance bill.
- Don't pay in full up front. Let the claim process first so it's applied at the plan's allowed amount. If a provider won't bill Vault Admin Services, you can self-submit your claim through your Member Portal.
You never have to figure this out alone — before or after you join:
- Reach us at 646-328-6968 or through the contact page. Already a member? Send a Solo Concierge request directly.
- We'll identify in-network options, verify a provider's participation, and call offices on your behalf to confirm they'll work with your plan.
- We'll guide you through prior authorization when a service requires it, coordinated through the Vault Cares Network.
- Confirm network status before your appointment — a two-minute call saves surprises later.
- Bring your ID card to every visit. It carries everything the office needs to verify your plan and bill correctly.
- Facing a big procedure? Use the Vault Cares Network for expert second opinions and the Fairos Care Navigation Team at 855-426-1100 to find the best facility on cost and quality before you commit.
- If an office says they need a referral, that's their own policy — Solo never requires one.
