What 92325 covers
This service covers a physical change to an existing contact lens, such as polishing or altering the lens. It is distinct from evaluating the patient for a new lens fit and from supplying a replacement lens. Ophthalmologists and optometrists may perform or supervise contact lens care in an office setting; trained staff may carry out the modification under the required physician supervision.
Report 92325 when the record identifies the lens modified, the change made, and the clinical reason for altering it. The documentation should distinguish the work from fitting a lens or replacing one. CMS classifies the service as incident-to, so it may be billed only when performed under physician supervision. CMS assigns zero work RVUs, with practice-expense and malpractice RVUs; office and facility practice-expense values are the same.

92325 billing questions
When should 92325 be used instead of a contact lens fitting code?
Use 92325 for a physical alteration to an existing lens, such as polishing. A fitting code describes the fitting service, not the alteration itself.
How is 92325 different from 92326?
92325 represents altering an existing lens. 92326 represents replacing a contact lens; use the code that matches the service actually performed.
What documentation supports 92325?
Document which lens was modified, what physical change was made, and why the alteration was needed. The record should make clear that the service was not a fitting or replacement.
Can staff perform the modification and bill 92325?
CMS classifies 92325 as incident-to and permits billing only when the service is performed under physician supervision.
Can 92325 be reported with a contact lens fitting code?
A fitting and a distinct physical lens modification may be separate services when both are performed and documented. The record should identify each service rather than treating fitting work as a lens alteration.
