What 68135 covers
An ophthalmologist typically uses a destructive technique, such as cryotherapy or cautery, to treat a lesion on the conjunctiva, the membrane covering the eye’s front surface and lining the eyelids. A conjunctival papilloma is one example of a lesion that may be treated this way. The service may be performed in an office or facility setting, depending on the procedure and patient circumstances.
Select this code when the lesion is destroyed rather than removed by excision or sampled for diagnosis. Document the treated eye, lesion location and characteristics, and method of destruction. The 10-day global period includes related postoperative visits during that period. For bilateral treatment, modifier 50 is paid at 150%. When multiple procedures occur in one session, the highest-valued procedure is paid in full and the others at 50%. Medicare does not pay an assistant at surgery for this code; co-surgeons and team surgery are not permitted.

68135 billing questions
When should this code be used instead of a conjunctival excision code?
Use this code when the lesion is destroyed in place. Use an excision code when the lesion is surgically removed; the applicable excision code depends on the procedure and lesion circumstances.
How does this differ from a conjunctival biopsy?
Destruction treats the lesion without removing a specimen for histologic examination. A biopsy is used when tissue is sampled for diagnosis.
Does the 10-day global period include follow-up visits?
Related postoperative visits during the 10 days after the procedure are included in the global period.
How is bilateral treatment reported?
For bilateral treatment, report modifier 50; CMS values the bilateral procedure at 150%.
What happens when another procedure is performed in the same session?
Under the standard multiple procedure reduction, the highest-valued procedure is paid in full and other procedures are paid at 50%.
Can an assistant surgeon or co-surgeon be reported?
Medicare does not pay an assistant at surgery for this code. Co-surgeons and team surgery are not permitted.
