Two appointments, two payers
| What it is | Why you went | Billed to |
|---|---|---|
| Routine vision exam | You need glasses or a check | Vision plan, if you have one; otherwise you |
| Medical eye exam | A symptom, an injury, or monitoring a condition | Medical insurance |
The distinction is decided by the reason for the visit, and the practice records it. If you go in for new glasses and mention a symptom, the visit can become a medical one, which is clinically correct and financially different.
Say which one you want when you book:
“I’m coming for a routine vision exam for glasses. Is that billed to vision coverage or to medical?”
Refraction is its own line
Refraction is the part of the exam where lenses are switched and you say which is clearer. It determines your prescription and it is frequently billed as a separate charge that is not always covered, including under Medicare and under some medical plans.
It is small relative to a scan or a procedure, and it is the single most common line people query on an eye bill because it appears when they thought the exam was covered.
“Is refraction included, or is it a separate charge?”
Glasses are a third question entirely
The exam, the prescription and the eyewear are separate purchases, and a plan that covers one may not cover the others in the way you expect. A vision plan typically provides an allowance toward frames and lenses rather than paying in full, with coatings and upgrades charged on top.
You are entitled to your prescription. You can take it anywhere, including online, and a practice cannot require you to buy from it.
On Medicaid
New York Medicaid covers optical services on a usual frequency of once in 24 months, which in practice means an examination and, when the exam produces a prescription, one pair of glasses with Medicaid-approved frames.
More often is possible with a documented reason, most clearly a prescription change of more than half a diopter. Broken glasses get repaired; lost or unrepairable ones are replaced with the same prescription and frame style. Children’s vision coverage runs under broader federal requirements than adult coverage. The full detail.
On Medicare
Original Medicare generally does not cover routine eye exams or glasses, with narrow exceptions such as after cataract surgery. It does cover medical eye care, and it covers certain screenings for people at higher risk of specific eye conditions.
Some Medicare Advantage plans add a vision benefit. The terms differ widely between plans, which makes it one of the things worth comparing during the autumn window. Advantage against Original Medicare.
If you have no coverage
Ask for the self-pay price for the exam and refraction together, as one number.
Community health centers sometimes have vision services on site, billed on a sliding scale by income. Search by ZIP at findahealthcenter.hrsa.gov.
Schools of optometry run clinics at reduced fees under supervision.
Take the prescription with you. Once you have it, the eyewear is a separate purchase you can make anywhere at any price point.
Questions people ask
How much does an eye exam cost?
It depends on whether it is a routine vision exam or a medical eye exam, and whether refraction is billed separately. Ask for both numbers as one quote.
Why did I get a bill when my insurance covers eye exams?
Usually one of two reasons: the visit was billed as medical rather than vision, or refraction was charged separately.
Does Medicare cover eye exams?
Original Medicare generally does not cover routine vision, though it covers medical eye care and certain risk-based screenings. Some Medicare Advantage plans add a vision benefit.
How often does Medicaid cover glasses in New York?
Usually once every 24 months, and sooner with a documented reason such as a prescription change of more than half a diopter.
Can I take my prescription somewhere else?
Yes. You are entitled to your prescription and no practice can require you to buy eyewear from it.
What is refraction?
The part of the exam that determines your lens prescription. It is often a separate charge and is not always covered.
