What 68520 covers
An ophthalmologist, often an oculoplastic surgeon, removes the lacrimal sac. This operation may be selected for chronic or recurrent dacryocystitis or other sac disease when removing the sac is the planned treatment. It is distinct from creating a new drainage route while preserving the sac. The procedure is generally performed in an operative setting, and the operative report should identify the affected side, the sac condition, and the extent of excision.
Report the code for the sac excision itself, not for a lacrimal gland procedure or a limited diagnostic sample. Documentation should support why the sac was removed and describe the work performed. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care. For bilateral surgery, modifier 50 is paid at 150%. When other procedures are performed in the same session, the highest-valued procedure is paid in full and additional procedures are subject to the standard 50% multiple-procedure reduction. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.

68520 billing questions
How does sac removal differ from a dacryocystorhinostomy?
This code represents removal of the lacrimal sac. A dacryocystorhinostomy creates a drainage bypass while retaining the sac.
Can a sac biopsy be reported with the excision?
A separate biopsy code is generally for sampling when the sac is not being removed. The operative documentation should support the distinct work if both procedures are reported.
How is bilateral sac removal reported?
Report bilateral surgery with modifier 50; CMS pays the bilateral procedure at 150%.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
May an assistant or co-surgeon be reported?
Assistant-at-surgery payment requires documentation of medical necessity. Co-surgeons and team surgery are not permitted.
