Go to Settings > General > Accumulator Tracking.
The default setting for all payers can be found on Settings > General at the bottom of the page. Here you can set the default values for in-network and out-of-network benefits. You can utilize your Net Rate Per visit as a way to estimate in and out of network deduction amounts for spending accumulator settings.
Additionally, individual payers can have their own override for the deduction amount by going to Settings > Payers and clicking edit on the payer you want to update. Under the Compliance / Billing Rules tab scroll to the bottom to Insurance Coverage to set the override amount for this specific payer.
