What Is Managed Care
Managed care is a health insurance model where your insurer contracts with a limited network of hospitals, doctors, and facilities to deliver care at negotiated rates. The insurer controls costs by requiring prior authorization for certain procedures, limiting which providers you can see without penalties, and determining what treatments count as medically necessary.
Unlike traditional indemnity insurance, managed care plans actively manage your utilization. This means the insurer doesn't simply pay claims after the fact. They decide upfront whether a treatment is covered, often before you receive care. When claims are denied, the denial letter often cites "not medically necessary" or "not a covered benefit under your plan".
How It Affects Claims and Denials
Managed care creates specific barriers that lead to claim denials:
- Prior Authorization Requirements: Many procedures, imaging, and specialist referrals require pre-approval. If your doctor doesn't request authorization before treatment, the claim can be denied retroactively, even if the service was medically necessary and performed at an in-network facility.
- Medical Necessity Determinations: The insurer's medical director (often not your treating physician) decides whether a treatment meets their definition of medically necessary. A procedure approved by your doctor may be denied if the insurer's criteria don't align with yours.
- Network Restrictions: Out-of-network providers typically have higher patient responsibility. If you see an out-of-network specialist without authorization, the claim denial may reference "non-participating provider" rather than the actual clinical merit of the treatment.
- Quantity Limits: Managed care plans often cap services like physical therapy (commonly 20-30 visits per year) or imaging studies. Claims beyond these limits are routinely denied, regardless of clinical need.
Reading Your EOB
Your Explanation of Benefits (EOB) reveals how managed care affected your claim. The EOB shows what the provider charged, what your plan's contracted rate is (often 40-60% lower than the billed amount), and the denial reason. When managed care denies a claim, the EOB denial code typically falls into categories like "not medically necessary," "requires prior authorization," or "exceeds plan limits." These denials are contestable through your plan's appeal process.
Internal and External Appeals
Managed care plans are required by state insurance regulators to offer at least two levels of appeal before you can pursue external review. An internal appeal goes back to the same insurance company. If denied internally, you can request an external appeal, where an independent reviewer (not employed by the insurer) evaluates your case. Most states require insurers to respond to external appeals within 72 hours for urgent claims and 30 days for standard claims. This is your strongest tool when managed care denies necessary treatment.
Common Questions
- If my doctor says a treatment is necessary but managed care denies it, can I appeal? Yes. File an internal appeal immediately, citing your doctor's clinical notes and any published medical guidelines supporting the treatment. If denied internally, request an external appeal. Provide peer-reviewed evidence, similar case outcomes, and your specific clinical circumstances. External reviewers often overturn denials when clinical evidence is strong.
- What happens if I don't get prior authorization before a procedure? The claim may be denied, but not automatically. Your insurer must prove the authorization was required and that you had notice of the requirement. If prior authorization was waived in the past for similar procedures, you may have grounds to appeal the denial.
- Are there state regulations that limit what managed care plans can deny? Yes. Most states regulate "medical necessity" definitions, require timely claim decisions (usually 30 days), and mandate external appeal access. Contact your state's Department of Insurance if you believe your plan violated these requirements. State regulators have authority to compel payment of improperly denied claims.
