Reimbursement
Underpayments, downcodes, and the gap between the record and the remittance.
A paid claim is not always a correctly paid claim. This resource center collects the firm’s notes on government and commercial reimbursement: what to compare, which Insights explain a live issue, and when the no-show calculator is only an estimate.

First pass
First steps you can take today
These steps organize the question. They are not a substitute for counsel.
- 1
Pull five recent remittances that look short and write down the reason codes.
- 2
Match each one to the note, the codes billed, and the contract or CMS schedule.
- 3
Label the shortfall as a denial, a downcode, or a reduced allowed amount.
- 4
If missed visits are part of the leak, run the calculator before changing a patient policy.
Stack the remittance before you argue the number
Most short pays are not dramatic denials. They are a reduced allowed amount, a downcoded visit, a modifier the system ignored, or a fee schedule the plan updated. The useful comparison is the remittance, the contract or CMS schedule, and the note from that date of service.
Appeal windows are often shorter than the time it takes to pull a year of claims. If the remittance is already weeks old, read the timely-filing and appeal language before building a larger sample.
Estimates are not recoveries
The no-show calculator on the tools page estimates lost appointments. It does not decide whether a charge is allowed. A patient policy, the plan contract, and state rules still control.
Counsel for a live underpayment sits on the reimbursement practice page. This center is the reading list and the first comparison, not a demand letter.

Common questions
- Is an underpayment the same as a denial?
- No. A denial refuses the claim. An underpayment pays something, just not the amount the record and the contract appear to support. The evidence and the deadline are often different.
- Does this page tell us what we are owed?
- No. It explains how to compare a remittance with the chart and the published fee schedule or contract. A dollar figure for a specific claim needs the file.
- Where is the no-show calculator?
- It lives on the tools page and at /recovery-calculator/. The result is a planning estimate, not a promise that the practice can bill the patient.
