202508 – Comprehensive Ophthalmological Service

Understanding the Required Elements of a Comprehensive Ophthalmological Service (92004 and 92014)

This past week I was speaking in St. Louis and Chicago. I am often surprised by questions I get when the topic of the question pertains to a myth that I thought had been well disproven years ago. However, many of the same things continue to pop up during lectures and via email questions. A common misconception among providers is that 92004 and 92014 are “routine vision exam” codes. In reality, these are medical eye examination codes, not vision plan codes. While many vision plans may appropriate them as the once-per-year “routine exam” benefit, their proper use extends far beyond that context. If a patient has a medical condition that warrants a comprehensive ophthalmological service, these codes may be billed multiple times per year, provided all required elements are performed and medically appropriate for the reason for visit.

Definition of the Codes

• 92004 – Comprehensive ophthalmological service, new patient, one or more visits.
• 92014 – Comprehensive ophthalmological service, established patient, one or more visits.

Both describe a medical examination and evaluation with initiation or continuation of a diagnostic and treatment program. They are not limited to refractive care or “annual checkups.”

Required Elements
To properly bill 92004/92014, the following must be included and documented:

1. History – Chief complaint, present illness, and relevant past/family/social history.
2. General Medical Observation – Mental status and overall external appearance.
3. External and Adnexal Examination – Eyelids, conjunctiva, cornea, sclera, anterior chamber, iris, and lens.
4. Ophthalmoscopy – Evaluation of internal ocular structures: retina, vessels, macula, and optic nerve.
5. Gross Visual Fields – Confrontation testing or other appropriate screening.
6. Basic Sensorimotor Evaluation – Ocular alignment and motility.
7. Initiation or continuation of a diagnostic and treatment program

A retinal exam is required, but dilation itself is not. The exam may be accomplished with direct/indirect ophthalmoscopy, widefield imaging, OCT, or other methods when dilation is contraindicated or declined. If dilation is deferred, document the reason clearly.

Key Distinction from Vision Plan “Routine Exams”
Vision plans often apply 92004/92014 for their yearly “routine vision exam” benefit, which can blur understanding of these codes. In medical billing, however, these codes are appropriate whenever a comprehensive ophthalmological service is indicated, regardless of frequency. The critical distinction is that the service must address a medical diagnosis and include all required elements.

92004 and 92014 are comprehensive medical eye exam codes, not “routine vision exam” codes. They can (and should) be used whenever the patient’s condition warrants a full ophthalmological work-up, even multiple times per year. Proper documentation of the required elements ensures accurate billing and reflects the thorough care optometrists provide.
