Medical insurance, vision plans and the optometry superbill
Optometry is one of the few professions where a single patient might have two completely separate benefits for the same office visit. A vision plan covers routine eye exams and eyewear allowances. Medical insurance covers the diagnosis and treatment of eye disease, injury and symptoms. Which one applies depends on the reason for the visit, not on the equipment you used, and the chief complaint in your note is what a reviewer will look at first.
That distinction shapes the superbill. A patient filing an out-of-network medical claim needs a superbill with a medical diagnosis listed first, such as glaucoma suspect, dry eye or a corneal foreign body, followed by the exam and testing codes. A patient with an out-of-network vision benefit usually files through the vision plan’s own claim form instead, and may only need your itemized receipt. When a visit has both parts, such as a glaucoma follow-up that also updates a glasses prescription, put the medical services and refraction on separate lines so each benefit can be applied correctly.
Common optometry codes
| Code | What it covers | When to use it |
|---|---|---|
| 92002 / 92004 | New patient eye exam, intermediate / comprehensive | No visit with you or a same-specialty colleague in your group for three years |
| 92012 / 92014 | Established patient eye exam, intermediate / comprehensive | Follow-ups and annual medical exams |
| 99202-99215 | Office E/M visits | Medical visits leveled by decision making or time |
| 92015 | Refraction | Determining a glasses prescription; often patient-paid |
| 92083 | Extended visual field | Glaucoma and neuro-ophthalmic workups |
| 92133 / 92134 | OCT, optic nerve / retina | Glaucoma monitoring or macular and retinal disease |
| 92250 | Fundus photography | Documenting retinal or optic nerve findings |
| 92201 | Extended ophthalmoscopy with drawing | Peripheral retinal disease such as tears or holes |
| 76514 | Pachymetry | Corneal thickness in glaucoma suspects |
| 65222 | Corneal foreign body removal | Slit lamp removal, with RT or LT |
| S0620 / S0621 | Routine exam with refraction | Plans that require these HCPCS codes for routine care |
Eye codes versus E/M codes
The 92000-series eye codes are not leveled by time or decision making. Intermediate exams evaluate a new or existing condition without a full workup of the visual system; comprehensive exams evaluate the whole visual system and usually include dilation when indicated and the start of a diagnostic or treatment plan. E/M codes, by contrast, are chosen by medical decision making or total time on the date of service. You can use either set, but not both for the same visit, and the documentation must support whichever you pick.
A patient counts as new if neither you nor anyone of the same specialty in your group has seen them in the past three years. That rule applies to both code families.
Refraction, routine exams and the S-codes
Medicare excludes refraction by statute, so Medicare patients pay for 92015 themselves; modifier GY flags it as excluded if you submit it. Many commercial medical plans also exclude refraction. Some payers want routine exams reported as S0620 or S0621 instead of an eye code plus 92015. Medicare does cover a yearly diabetic eye exam for people with diabetes and glaucoma testing once every 12 months for people at high risk, so those visits belong on the medical side.
Diagnostic testing: OCT, fields and photos
Most ophthalmic tests, including 92083, 92133, 92134 and 92250, are defined as unilateral or bilateral, so bill one unit without a bilateral modifier. 92133 and 92134 are generally not payable on the same date. Every test needs a written interpretation and report in the chart; if you only interpret a test performed elsewhere, modifier 26 may apply. Many payers also set frequency limits for repeat imaging, especially for glaucoma suspects.
Documentation tips
- State the chief complaint in the patient’s own words; it decides medical versus routine billing.
- Record whether the patient was dilated, and why not if you skipped it.
- Keep a dated, signed interpretation for every diagnostic test.
- Code laterality and glaucoma stage to the full specificity ICD-10 allows.
How to fill in this optometry superbill
- Enter your practice name, your name with OD, license number, NPI and EIN. The NPI field validates the check digit.
- Add the patient’s details, then the medical insurance carrier, member ID and group number.
- Enter diagnoses with the medical reason for the visit first. The code field suggests common eye diagnoses and fills in descriptions.
- Add each service with date, code, modifier, place of service, diagnosis pointer, units and fee. Keep refraction on its own line.
- Enter the amount paid so the balance calculates, type your signature, and note any eyewear billed separately.
- Check the missing-field list, then Print / Save as PDF on US Letter.
