The CPT codes for eye exams vary based on the type of exam performed (e.g., routine or medical), the complexity of the service, and any additional diagnostic tests conducted during the visit. Proper selection of these codes depends on the patient’s condition, the purpose of the visit, and the services rendered.
Key Components of an Eye Exam
- Comprehensive review of medical and ocular history.
- Examination of visual acuity, ocular health, and refraction.
- Screening for eye diseases such as glaucoma, cataracts, or macular degeneration.
- Additional diagnostic tests as necessary.
Specific CPT Codes for Eye Exams
General Eye Exam Codes
These codes apply to general eye exams, including routine checks and screenings for vision correction or basic ocular health.
- CPT 92002: Ophthalmological services; intermediate evaluation and management, new patient.
- Lay Term: For new patients with specific eye complaints requiring a focused evaluation of one or more ocular conditions.
- Documentation: Include patient history, examination findings, and medical decision-making details.
- CPT 92004: Ophthalmological services; comprehensive evaluation and management, new patient, one or more visits.
- Lay Term: For new patients requiring a detailed examination of the entire visual system, including medical history, general eye health, and refraction if performed.
- Documentation: Ensure thorough documentation of all components evaluated.
- CPT 92012: Ophthalmological services; intermediate evaluation and management, established patient.
- Lay Term: For established patients presenting with new or ongoing eye conditions requiring evaluation and management.

- Lay Term: For established patients requiring a detailed examination of the visual system.
- Billing Tip: Distinguish between intermediate and comprehensive services based on the scope of the exam.
Vision Screening and Refraction Services
These codes are used for routine vision screening and refractive testing.
- CPT 92015: Determination of refractive state.
- Lay Term: Includes testing to determine the refractive error and prescription for glasses or contact lenses.
- Billing Tip: Not typically covered by insurance unless medically necessary; confirm coverage before billing.
Specialized Diagnostic Tests
For eye exams requiring advanced diagnostic testing, the following codes are commonly used:
- CPT 92133: Scanning computerized ophthalmic diagnostic imaging, posterior segment, with interpretation and report; optic nerve.
- Lay Term: Used for imaging the optic nerve, often for glaucoma diagnosis or monitoring.
- Documentation: Include interpretation of the images and relevance to the patient’s condition.
- CPT 92134: Scanning computerized ophthalmic diagnostic imaging, posterior segment, with interpretation and report; retina.
- Lay Term: Imaging of the retina, commonly used for conditions like macular degeneration or diabetic retinopathy.
- Billing Tip: Ensure the medical necessity is well-documented.
- CPT 92250: Fundus photography with interpretation and report.
- Lay Term: Photographic documentation of the retina, used to monitor conditions such as diabetic retinopathy or macular degeneration.
- Billing Tip: Confirm payer policies regarding coverage for fundus photography.
- CPT 92285: External ocular photography with interpretation and report, for documentation of external eye conditions.
- Lay Term: Includes imaging of the external eye structures, such as the eyelids or conjunctiva.
- Key Use: Used for monitoring external ocular diseases or injuries.
Screening for Specific Conditions
For patients requiring screening for specific conditions, the following codes apply:
- CPT 99173: Screening test of visual acuity, quantitative, bilateral.
- Lay Term: Standard screening test for visual acuity.
- Billing Tip: Typically billed during routine wellness visits or as part of a comprehensive eye exam.
- CPT 99174: Instrument-based ocular screening (e.g., photoscreening), bilateral, with on-site analysis.
- Lay Term: Used for screening children or non-verbal patients for vision problems.
- Documentation: Include details of the findings and any follow-up recommendations.
Modifiers and Billing Guidelines
Modifiers
- Modifier 25: Use for separately identifiable E/M services provided on the same day as the eye exam.
- Modifier 59: Use for distinct procedural services when additional diagnostic tests are performed.
Documentation Requirements
- Clearly specify the purpose of the exam (e.g., routine vision check, medical eye evaluation).
- Include all findings from the exam, diagnostic tests performed, and the medical necessity for any additional services.
- Ensure proper use of modifiers to indicate separately billable services.
Common Billing Errors
- Using incorrect codes for routine vision exams versus medical eye exams.
- Failing to document medical necessity for diagnostic tests.
- Omitting modifiers for additional services or separate conditions.
Practical Scenarios and Coding Examples
Scenario 1: Comprehensive Eye Exam for a New Patient
- Patient: A 40-year-old presenting for a routine eye exam with no known medical conditions.
- Codes: CPT 92004 (comprehensive evaluation).
- Documentation: Include findings for visual acuity, ocular health, and refraction if performed.
Scenario 2: Diagnostic Imaging for Glaucoma Monitoring
- Patient: A 60-year-old with diagnosed glaucoma undergoing a follow-up evaluation.
- Codes: CPT 92133 (optic nerve imaging) + CPT 92014 (comprehensive evaluation for an established patient).
- Notes: Document findings from the imaging and their relevance to the glaucoma diagnosis.
Scenario 3: Refraction Service for Prescription Update
- Patient: A 25-year-old requesting a new glasses prescription.
- Codes: CPT 92015 (refraction).
- Billing Tip: Inform the patient of potential out-of-pocket costs if not covered by insurance.
