A claim rejection generally means the claim was not accepted for adjudication. A denial reflects a payer's decision not to pay all or part of an adjudicated claim. Check the actual response before deciding whether to correct, submit again, or appeal.
To investigate a physical therapy claim denial, start with the payer's actual response, compare it with the submitted claim and supporting records, and choose the next action under the applicable instructions. A denial code is a starting point—not a complete root-cause diagnosis.
Prioritize denied therapy claims by the risk of missing a deadline, their current status, and the action available—not balance or age alone. Keep the rest of accounts receivable visible so urgent denial work does not leave other claims without an owner.
