Verified for the 2026 Plan Year & NY DFS Network Regulations
Quick Answer: Yes, both systems participate widely in NYC, but their network boundaries vary by product type. Under a newly established three-year agreement, Mount Sinai is fully IN-NETWORK for Anthem Blue Cross Blue Shield across commercial employer groups, Medicaid, Child Health Plus, and Essential Plans, but strictly OUT-OF-NETWORK for Anthem Individual Marketplace and Medicare Advantage products. Conversely, NYU Langone accepts Anthem across both individual and group plans but heavily limits participation in budget, narrow-network “Select” or “Pathway” Exchange products, restricting those patients via tiered copays.
Health Insurance Plans that Mount Sinai & NYU Langone Accept
Mount Sinai and NYU Langone are two of the most respected healthcare providers in New York City. However, in 2026, “accepting” a plan doesn’t always mean you are fully covered. Carriers have shifted to “tiered” networks, and recent contract resolutions have created different rules for employer-based plans versus individual marketplace plans
Mount Sinai accepts a variety of health insurance plans, but 2026 brought major changes to their relationship with Anthem (formerly Empire):
-
HMO Plans: Require a Primary Care Provider (PCP) to coordinate care and provide referrals. These typically have the lowest premiums.
-
PPO Plans: Offer the most freedom to see specialists without a referral.
-
Value-Based Care (New for 2026): Many Mount Sinai contracts now include “Value-Based” requirements. This means certain non-emergency procedures may require a 14-day pre-authorization even if the doctor is in-network.
The Anthem BCBS & Mount Sinai “Split”
As of April 13, 2026, a new three-year agreement was reached, but it does not apply to everyone.
-
Employer/Group Plans: IN-NETWORK. If you have Anthem through your job, you have full access to Mount Sinai hospitals and doctors.
-
Individual Marketplace Plans: OUT-OF-NETWORK. Mount Sinai has confirmed that their new contract does not extend to Anthem’s Individual Marketplace or Medicare Advantage plans. If you bought your plan on the NY State of Health Exchange, you will likely face out-of-network costs here.
To find out if your health insurance plan is accepted by Mount Sinai, you can call the customer service number on your insurance card or visit the Mount Sinai website. You can also use the insurance finder tool on the Mount Sinai website to search for plans by name or type.
NYU Langone Health: The “Tier 1” Advantage
NYU Langone remains a highly selective system. In 2026, they moved toward “Tiered” access to manage high patient volume.
-
Note for 2026 Selectivity: NYU Langone has significantly limited its participation in “Standard” Bronze and Silver plans. We are seeing NYU Langone turn away patients with “Select” or “Pathway” narrow-network cards.
-
Tier 1 vs. Tier 2: Many plans (like Aetna and United) now categorize NYU Langone as a Tier 1 provider for their premium plans, but a Tier 2 (higher cost) provider for budget plans. Always verify your specific “Network Name” before your appointment.
-
The Anthem Alternative: While Anthem is split at Mount Sinai, it remains fully In-Network (both Group and Individual) for NYU Langone. This makes NYU a primary alternative for Anthem Marketplace members who were previously Sinai patients.
Which Plans Do Both Systems Accept?
While dozens of small administrators exist, these are the primary carriers with verified 2026 contracts at both Mount Sinai and NYU Langone:
| Carrier | Mount Sinai (2026) | NYU Langone (2026) |
| Aetna | In-Network (HMO/PPO) | In-Network (Often Tier 1) |
| Anthem BCBS | Employer/Group Only | In-Network (All Tiers) |
| United/Oxford | Freedom & Liberty Networks | Freedom & Liberty Networks |
| Cigna | PPO & Open Access Plus | PPO & Open Access Plus |
| EmblemHealth | VIP & Prime Networks | VIP & Prime (Limited) |
Important Note: This is not an exhaustive list. Carrier networks can change monthly. We recommend using the insurance finder tools on the Mount Sinai or NYU Langone websites to search for your specific plan sub-type (e.g., “Oxford Liberty” vs “Oxford Metro”).
How to Verify Your Coverage
Before scheduling a procedure, take these two steps:
-
Check the 2026 Authorization Code: Ask your doctor if your procedure requires a “Value-Based” authorization.
-
Confirm the Network Name: Don’t just ask “Do you take Aetna?” Ask “Do you participate in the Aetna [Network Name] for 2026?”
Want help navigating these networks? The 2026 split between “Group” and “Individual” coverage has made NYC insurance more complex than ever.
