How this calculator works

Adjusted allowed = base allowed amount x units x payer multiplier x adjustment factor. Expected payer payment = adjusted allowed - patient responsibility.
Adjusted allowed amount = base allowed amount * units * payer multiplier * (1 + adjustment percent / 100). Expected payer payment = adjusted allowed amount - patient responsibility.

Inputs explained

Base allowed amount

Entered fee schedule, contract, or historical allowed amount.

Payer multiplier

A contract factor such as 1.05 for 105% of the base.

Adjustment percent

Optional geography, site, or policy adjustment entered by the user.

Understanding your results

Expected reimbursement is a planning estimate. Compare with actual EOB values and contract terms before appeal or posting changes.

Example scenarios

Contract estimate

$120 base allowed x 2 units x 1.05 multiplier with 0% adjustment and $40 patient responsibility estimates $212 payer payment.

Frequently Asked Questions

Does this look up CPT rates?
No. Enter your own base allowed amount or fee schedule value.
Can I use RVUs?
Yes, if you first convert RVUs and conversion factor into a base allowed amount or use the base input as the RVU-derived amount.
Does it include modifiers?
Not automatically. Use the modifier impact calculator for modifier-specific adjustments.
