Optometry Billing Services

Optometry billing is a two-lane road. Routine eye exams and glasses often go through a vision plan, while eye disease, injuries, and medical visits go through health insurance. A single patient can switch lanes mid-visit if the exam turns up cataract changes or a retinal problem.

That split is where many optometry practices lose revenue. Claims go to the wrong plan, tests are not tied to a medical diagnosis, or medical visits are billed as routine. Westmont connects optometry practices with vetted billing experts who understand both vision and medical plans. Good optometry billing services help you choose the right lane at check-in, document the reason for the visit, and follow up on claims from both sides.

Billing challenges in optometry

Medical versus routine. Medicare and many health plans do not pay for routine exams or refraction, while vision plans do. Billers help front desk staff ask the right question at check-in and bill the correct plan.

Choosing exam codes. Eye exam codes and general office visit codes can both apply, but not for the same service. Billers apply the payer's preference and make sure documentation supports it.

Refraction is often not covered. Many medical plans treat refraction as a patient-paid service. Billers confirm this and prepare patient notices where needed.

Diagnostic testing rules. Tests such as imaging and visual fields usually need a medical diagnosis and a clear reason, and payers limit how often they pay. Billers match each test to a diagnosis and frequency policy.

Credentialing with two plan types. A practice may be in a vision network but not a medical one. Billers track both enrollments and fix gaps.

Frame and lens claims. Retail items follow vision plan fee schedules, authorizations, and benefit periods. Billers keep these separate from professional service claims.

Co-management and global periods. When shared with a surgeon, post-operative visits may be included in the surgeon's payment. Billers check agreements before billing.

Frequently asked questions

Should an eye exam be billed to vision insurance or medical insurance?

It depends on why the patient came in. Routine exams for glasses usually go to a vision plan. Visits for symptoms, disease, or injury, or follow-up of a medical condition, usually go to health insurance. Document the chief complaint and diagnosis clearly so the claim goes to the right place.

Does Medicare cover routine eye exams?

Original Medicare generally does not cover routine eye exams or refraction, though it covers certain medical eye services such as diabetic eye exams and glaucoma screening for eligible patients. Some Medicare Advantage plans add vision benefits. Check current Medicare rules and the patient's plan.

What is the difference between 92014 and 99213?

92014 is an eye exam code for comprehensive care of an established patient, and 99213 is a general office visit. Payers differ on which they prefer, and both cannot be billed for the same service. Pick the code that fits the documentation and the payer's policy.

Why are optometry diagnostic test claims denied?

Common reasons are missing diagnosis links, testing done too frequently, tests seen as screening, and no separate interpretation report. A billing partner can review denials, update your templates, and build payer-specific rules so tests are supported the first time.
