How contractual adjustment works
Every payer a provider contracts with sets an allowed amount for each procedure code, usually lower than the provider's standard billed rate. When a claim is processed, the payer's remittance advice shows the billed charge, the allowed amount and the contractual adjustment between them, alongside whatever it actually pays and the patient's share.
Because the adjustment is a term of the payer contract rather than a bad debt, it posts to a separate contractual adjustment account, not to bad debt expense, and it should never appear on a patient statement as an amount owed. Practices track contractual adjustments by payer to spot underpayments and to negotiate future contract rates. Some practices also compare contractual adjustments against the fee schedule published in the payer contract each quarter, since payers occasionally underpay relative to what the contract specifies, and catching this early protects revenue that would otherwise be missed.
Example
A clinic bills $500 for a procedure. Its contract with the insurer sets the allowed amount at $350, so $150 is posted as a contractual adjustment and written off immediately. The insurer pays $280 of the $350 allowed amount, leaving a $70 patient copay. The original $500 charge never becomes patient responsibility beyond that $70. If the clinic later finds the insurer actually underpaid by $20 against the contracted rate, the billing team files an appeal referencing the contract terms rather than writing the shortfall off as a further adjustment.
Contractual adjustment in QuickBooks Online vs Xero
Not software-specific: contractual adjustments are usually calculated automatically by the practice management or medical billing system when it posts an electronic remittance advice, rather than typed manually into QuickBooks Online or Xero. The accounting system typically receives a summarized batch entry for revenue, adjustments and patient balance rather than a line per claim.
