What Is Allowed Services
Allowed services are the specific medical procedures, treatments, and healthcare visits that your insurance plan will actually pay for. Your plan document and the summary of benefits list these services. Insurance companies use "allowed" to distinguish between what they cover and what they don't, which matters directly when you file a claim or appeal a denial.
How Insurers Define Allowed Services
Your plan specifies allowed services in multiple ways. Some plans cover broad categories like "emergency room visits" or "preventive care," while others list individual CPT codes (the five-digit billing codes insurers use). When your doctor bills for a service, the insurer checks whether that specific service appears on your plan's allowed list. If it doesn't, you'll typically see "not covered" on your explanation of benefits (EOB).
Insurance plans also separate allowed services by type. Under the Affordable Care Act, all plans must cover ten categories of Essential Health Benefits, which include emergency services, hospitalization, and prescription drugs. However, within each category, individual services may or may not be allowed. For example, your plan must cover mental health services, but specific therapies like intensive outpatient programs might be excluded.
Prior Authorization and Allowed Services
Even when a service is technically allowed under your plan, many insurers require prior authorization before they'll pay. Prior authorization means your doctor must get written approval from the insurer before you receive the service. If you skip this step, the insurer may deny the claim even though the service is listed as allowed. When you appeal a denial based on lack of prior authorization, you're arguing that the service should have been approved because it meets medical necessity standards and fits within your allowed services.
Allowed Services Versus Exclusions
The opposite of an allowed service is an Exclusion. Exclusions are services explicitly listed in your plan as not covered. Common exclusions include cosmetic procedures, experimental treatments, and certain fertility treatments. Some plans exclude specific conditions entirely. When insurers deny claims, they often cite exclusions. Understanding which services your plan excludes helps you know whether you have grounds for an internal appeal or a state-level external appeal.
Reading Your EOB for Allowed Services Information
Your explanation of benefits (EOB) shows what the insurer considers allowed for each claim. The EOB lists the service code, the amount your provider charged, the "allowed amount" (what the insurer will consider for payment), what you owe, and what the insurer paid. If a service shows $0 as the allowed amount, that typically means it's not on your plan's allowed services list. This is the document you'll reference when appealing a denial.
State Regulations and Allowed Services
State insurance regulators require plans to clearly disclose allowed services. Your state's insurance commissioner's office can force insurers to provide detailed lists if you request them. Some states have specific rules about which services must be allowed. For example, many states mandate coverage for certain cancer treatments or post-mastectomy reconstructive surgery, making those services allowed regardless of what a plan document initially suggests.
Common Questions
- If a service isn't listed in my plan document, is it automatically not allowed? Not necessarily. Plans often use broad language that covers multiple services under one category code. If your doctor bills for a specific service that falls within an allowed category, it should be covered even if the exact service name doesn't appear. This distinction matters in internal appeals.
- Can an insurer change what services are allowed mid-year? No. Your plan's allowed services are locked for the calendar year. However, when you renew coverage the following year, the insurance company can modify what's allowed. Review any changes in your new plan documents carefully.
- How do I know if I have grounds to appeal a "not allowed" denial? Check whether the service falls within an allowed category on your plan, whether it meets medical necessity standards per your state's regulations, and whether you received prior authorization if required. These are the strongest appeal angles for allowed services disputes.
