“There are two verifications when dealing with insurance. Do you know the difference?”
If you are a dietitian taking insurance in your private practice, mastering the verification process is the key to getting paid on time and avoiding surprise bills for your patients. But one of the most common pitfalls is confusing an eligibility verification with a benefit verification.
While they sound similar, they serve two completely different functions in your billing workflow. Here is the breakdown:
1. Eligibility Verification: The “Active Status” Check
An eligibility verification is done to determine if a patient’s insurance information on file is correct and shows the patient as active with that plan for the scheduled date of service.
What it tells you:
- Is the policy currently active, or was it canceled last month?
- Is the patient’s name and date of birth correct in the insurance system?
- Who is the primary subscriber?
The Dietitian Context: Just because a patient hands you an insurance card doesn’t mean it’s valid today. Always check eligibility before their first session so you aren’t providing uncompensated care.
2. Benefit Verification: The “Coverage” Check
A benefit verification is done to determine exactly what coverage a patient’s plan has for your specific services. Just because a patient has active insurance (eligibility) does not mean they have coverage for Medical Nutrition Therapy (MNT). Here is how this plays out across different types of payers:
Medicare MNT Benefits: The Strict Baseline
While commercial plans vary, Medicare Part B provides a clear (if strict) baseline. For Medicare patients, MNT is covered only for Diabetes or Stage 3+ Chronic Kidney Disease (without dialysis).
- The Time Cap: The benefit is strictly capped at 3 hours in the initial year and 2 hours in subsequent years.
- The Referral Trap: A critical detail often missed is that the referral must come from an MD or DO. Referrals from Nurse Practitioners (NPs) or Physician Assistants (PAs) will lead to an automatic denial.
Commercial Plans: Flexibility Meets Legwork
Commercial plans are far more flexible but require much more legwork from your billing team. Unlike Medicare, many commercial plans cover a wide array of diagnoses, ranging from hypertension to eating disorders. However, they also vary wildly in terms of “unit” limits (how many sessions are allowed) and whether a physician’s referral or prior authorization is required.
Fully Insured vs. Self-Funded Plans
When verifying commercial benefits, pay close attention to whether a plan is fully insured or self-funded (often managed by a third-party administrator).
- Self-Funded Plans: Employers design these plans themselves, which means they can explicitly choose to exclude MNT entirely, even if the insurance carrier (like Aetna or BCBS) normally covers it.
- Pro Tip: Tracking what you learn from these verifications can save you future calls if you know a specific local employer group excludes MNT. However, tread carefully—employers can change their coverage details from year to year!
Portal Verifications vs. Calls
Digital portals like Availity, the UHC Provider Portal, and the Cigna Portal are excellent for quick eligibility checks. However, MNT is often “bundled” into broad, general categories in digital readouts.
If the portal doesn’t explicitly state the hour limit or the specific diagnosis code requirements for your CPT codes (like 97802), you must call the payer directly or use their online chat functions. Online chats are a highly recommended alternative to calling; they take about the same amount of time, but you can multi-task much easier while waiting for a representative.
The Bottom Line
Think of eligibility as your entry ticket—it gets you in the door. Benefits are the map that tells you exactly what you are allowed to do once you are inside. Skipping either step is a fast track to denied claims and frustrated patients. By doing both, you protect your practice’s revenue and build trust with your clients by giving them accurate cost estimates upfront.

The Great Debate: Who Should Check Benefits?
This brings us to one of the biggest dilemmas in the dietitian community: Whose responsibility is it to check benefits—the provider or the patient? There is no perfect answer, and there are distinct pros and cons to both approaches:
Option 1: The Dietitian Checks
- The Pros: You know exactly what the coverage is, you can ensure the right CPT and diagnosis codes are discussed, and you prevent surprise bills. This builds massive trust with your patients.
- The Cons: Unpaid admin time. Because MNT benefit verifications are not fully automated yet, this requires tedious portal hunting or long phone calls/chats. If you are a solo practitioner, that time is a serious business expense that eats directly into your profit margin.
Option 2: The Patient Checks
- The Pros: It puts the responsibility squarely on the policyholder and saves you hours of uncompensated administrative work each week.
- The Cons: It is notoriously difficult to get accurate information from insurance reps, even for us! Patients often do not know the right questions to ask (like asking about specific CPT codes or diagnosis exclusions). This frequently leads to patients being given the wrong information, resulting in denied claims, delayed care, and ultimately, an upset client.
Until insurance companies catch up and fully automate MNT benefit checks, how you handle this process is a major business consideration for your practice. I have done both at different points in my career, and the “right” choice often depends on your current caseload and administrative bandwidth.
