Your plan's price

Aetna has many contracts, and your plan uses one of them. Most providers' rates fall in the middle half shown above; the rate for your plan can be higher or lower. For a plan-specific estimate, sign in to Aetna's Find Care cost estimates.

What you would actually pay

The negotiated rate is the total the provider is paid. Your share depends on your plan. If you have not met your deductible, you usually pay the whole negotiated rate: at a $475 rate, that is $475. Once the deductible is met, coinsurance applies: at 20% coinsurance you would pay $95 and the insurer the rest. Plans with a flat copay for this service charge the copay instead.

Going out of network is different. The provider has no agreed rate with your insurer, so they can usually bill their full listed price. Federal and California law limit that in emergencies, for out-of-network clinicians at in-network hospitals and surgery centers and, under California-regulated plans, at other in-network facilities such as imaging centers and labs. Many HMO and EPO plans pay nothing for out-of-network care.

What the price covers

  • With contrast (CPT 72149) or without and then with contrast (72158) are different codes with different prices.

Where these numbers come from

Rates come from the price transparency files Anthem Blue Cross, Blue Shield of California, Aetna, UnitedHealthcare and Cigna publish. We clean the files before summarizing them and only show an insurer when enough providers report a rate. Medicare figures are from the 2026 Physician Fee Schedule. More on how these pages are built.
