Q: What's a fair price for CPT 90686?

Most patients should expect to pay no more than 2–3× the Medicare allowable for the same service. There's no straightforward Medicare allowable for this code (it's not on the standard physician fee schedule). A reasonable target when negotiating cash-pay or self-pay is somewhere between the Medicare rate and the in-network allowed amount your insurer would pay.

Plain-English reference for CPT 90686. What it covers, what it typically costs, and the billing errors patientbill.org looks for on this code.

Typical setting: Office
Medicare allowable: —

The Medicare allowable is the national non-facility rate from the CMS Physician Fee Schedule and is the most defensible "fair price" anchor. Commercial charges typically run 2–5× this number; hospital list prices can be much higher still.

What this code actually is

CPT 90686 is a preventive-care service — influenza vaccine, quadrivalent, preservative-free, im (0.5 ml). Under the ACA, in-network preventive services on the USPSTF and ACIP lists must be covered at $0 patient cost. If you're being asked to pay for this line, first check whether your insurer applied a deductible or copay (it shouldn't have). The most common reason patients get billed for 'free' preventive care is that the provider added a separate problem-oriented E/M code on the same day — the preventive portion is still $0, but the problem code can be balance-billed.
