What Is Concurrent Review
Concurrent review is an insurer's real-time evaluation of your inpatient hospital stay to determine whether continued care meets medical necessity standards. Unlike prior authorization, which happens before admission, concurrent review occurs during your hospital stay, typically starting on day one and repeating every 1-3 days depending on your condition and state regulations.
The insurer assigns a nurse reviewer to examine your medical record and clinical notes. That reviewer decides whether your current length of stay aligns with their medical necessity criteria and coverage guidelines. If the reviewer determines your care no longer meets these standards, the insurer can deny payment for future days, even if your doctor believes you need to remain hospitalized.
How Concurrent Review Works
The concurrent review process unfolds in specific stages:
- Initial notification: Your hospital must inform you and your doctor that concurrent review is underway, though this requirement varies by state. Some states mandate written notice within 24 hours; others have no explicit requirement.
- Daily or periodic assessments: The insurer's nurse reviewer examines your chart against their utilization management criteria. This includes diagnosis codes, treatment plans, lab results, and functional status. The reviewer compares your case to Medicare's Inpatient Prospective Payment System (IPPS) guidelines or the insurer's own protocols.
- Determination issuance: The insurer issues a determination that either approves continued coverage or issues a "Notice of Non-Coverage" (sometimes called a "Utilization Review Determination"). This notice explains which specific days will no longer be covered.
- Your response window: You typically have 60 days from the notice to file an internal appeal with the insurance company, then 180 days for an external appeal through your state's independent review organization if the insurer denies your claim.
Why Concurrent Review Matters
Concurrent review directly affects your bill. If the insurer determines on day 3 that you no longer need inpatient care, they stop payment. Your hospital will bill you for the remaining days at the full inpatient rate, which can exceed $2,000-$5,000 per day depending on your hospital and condition. This creates immediate financial exposure even while you're still hospitalized.
Your state's insurance regulations shape how much power the insurer has. States like New York require concurrent review decisions to be made by licensed clinical professionals and mandate immediate notification. Other states impose fewer requirements, giving insurers broader discretion. Check your state insurance commissioner's website for local concurrent review rules.
The timing also matters. If you receive a non-coverage notice while hospitalized, you can appeal immediately rather than discovering the denied days on your EOB after discharge. This gives you leverage to involve your hospital's patient advocate or your doctor in the appeal process while you're still receiving care.
Concurrent Review vs. Prior Authorization
Prior authorization happens before admission. You or your doctor request approval before the hospital stay begins. Concurrent review happens during the stay. If your condition changes or complications arise, concurrent review may approve additional days that prior authorization didn't initially cover. Conversely, concurrent review can withdraw approval if your clinical status improves faster than expected.
Your Appeal Rights
If the insurer denies continued coverage, you have two levels of appeal:
- Internal appeal: File with your insurance company within 60 days. Provide updated clinical documentation from your physician explaining why inpatient care remains medically necessary. Reference specific lab abnormalities, functional limitations, or safety concerns that justify continued hospitalization.
- External appeal: If the insurer upholds the denial, request an independent external review through your state's Department of Insurance or designated review organization within 180 days. External reviewers are independent doctors not employed by your insurer, giving you a second opinion on medical necessity.
Common Questions
- Can my insurer deny my entire hospital stay retroactively? No. Once you're admitted, the insurer cannot deny days that have already been deemed medically necessary during concurrent review. However, they can deny future days starting from the date they issue a non-coverage determination.
- What if I'm discharged before the concurrent review decision is made? The insurer still must issue a determination. If they deny coverage for days you already spent hospitalized, that denial appears on your EOB. You can then appeal the already-incurred charges.
- Who reviews my case, and do they have clinical expertise? Regulations vary by state. Federal law requires external reviewers to be licensed physicians in the relevant specialty. Internal reviewers employed by insurers are often nurses or physicians, but state law doesn't always mandate this. Request the reviewer's credentials when you appeal.
