My doctor analyses the patient’s vision and physical ocular structure, then prescribes a contact lens for trial. The patient may return several times, and be fitting with different brands, until the proper fit/brand is determined. The prescription, fitting, and inspection are completed by the doctor.

What would be the correct code for this procedure? Should we be billing an E/M service with a -25 modifier also?

Can anyone provide clarification on the difference between 92310 and 92314? Specifically – What is the definition of "independent technician?" A technician is not allowed to prescribe contact lenses, so this is perplexing.

Thank you.
