Concurrent Review
Definition
Concurrent review is a type of utilization review conducted by an insurance payer during an active inpatient hospital stay. The payer evaluates whether the patient continues to meet medical necessity criteria for inpatient hospitalization and whether the planned length of stay is appropriate.
Why It Matters
Concurrent reviews determine how many hospital days are approved for payment. A denied concurrent review can result in unpaid inpatient days and significant revenue loss. Preparing thoroughly for concurrent reviews ensures approval for medically necessary stays. Poor documentation leads to denial and billing disputes.
How It Works
During an inpatient admission, the hospital notifies the patient's insurance payer. The payer contacts the hospital's utilization review team or case management to discuss the patient's clinical status, reason for admission, and expected length of stay. Payer reviewers (typically nurses or care managers) ask clinical questions to verify medical necessity. They review whether the patient's condition requires continued inpatient care or could be managed in a lower level of care. Based on their assessment, the payer approves a certain number of inpatient days. If the clinical picture changes and the patient no longer meets inpatient criteria, the payer may deny continued coverage. The hospital must notify the patient when inpatient coverage is denied. Utilization review processes vary by payer and plan type.

What happens if a concurrent review denies continued inpatient stay?
If the payer determines the patient is no longer meeting medical necessity criteria for inpatient care, they may deny coverage for additional days. The hospital is notified, and you must arrange discharge or request an appeal. Denial of inpatient coverage does not relieve the patient of financial responsibility, but it may affect your billing and reimbursement options.
Who performs concurrent reviews?
Payers employ nurses or case managers to perform concurrent reviews. They contact the hospital during the stay to discuss clinical status and anticipated length of stay. Some payers contract with external utilization review companies. Reviews are based on medical necessity guidelines in the patient's insurance plan.
