What is the correct CPT code for the removal of a rust ring using a slit lamp?

1. CPT code 65222

2. CPT code 68761

3. CPT code 92014

4. CPT code 92004

The correct answer is: CPT code 65222

The removal of a rust ring using a slit lamp is categorized under a specific procedural context, and the correct CPT code for this scenario is 65222. This code corresponds to the removal of foreign bodies from the cornea, which is applicable for instances where a rust ring, a type of foreign body, is present and requires special tools like a slit lamp for safe extraction. The procedure typically involves careful examination and removal of the rust ring, ensuring the cornea remains intact and minimizing any further damage. The use of a slit lamp is critical in this case, allowing for a magnified view that aids in accurate removal. Other codes mentioned in the options refer to different types of services. For instance, codes 68761, 92014, and 92004 do not apply to the removal of foreign bodies from the cornea. Code 68761 refers to procedures related to the punctum, specifically eyelid procedures, and codes 92014 and 92004 pertain to comprehensive eye examinations but do not cover specific procedural interventions like the extraction of a rust ring. Thus, selecting CPT 65222 reflects both the specific procedure performed and the use of the slit lamp in accomplishing the task.
