The May coding top 10 selections include:

1. Performing Stent Procedures Without Cataract Surgery
   If we perform another procedure, other than cataract surgery, at the time of iStent or CyPass placement, is the patient responsible for payment?

2. Billing Bilateral Punctal Plugs
   How should I bill punctal plugs with Medicare patients? We always bill the eye code with modifier -25, along with 68761 -RT and 68761 -LT, however Medicare is no longer processing the claim.

3. Changing Billing Pattern of Exam Coding
   Our physician has consistently used E/M codes on almost all new patients. However, he’s now using Eye visit codes more often. Will this shift in coding raise any red flags?

4. Removing Tumors From Multiple Lids
   Our surgeon is performing a tumor excision from all four lids. How do I code this?

5. Billing for Orthoptists
   Can a certified orthoptist bill for testing services?

6. Paperwork Retention Time Period
   How long, by law, do we need to keep copies of superbills/billing records?

7. Billing Bilateral Contact Lens Fitting
   When performing 92313 Contact lens fitting for corneoscleral lens for both eyes, do we submit the code twice?

8. Coding Low- and High-Risk Glaucoma Suspect
   Our LCD policy no longer allows for glaucoma suspect unspecified. It only allows for low or high risk. How do we determine the appropriate code?

9. Coding for Superficial Keratectomy and Bandage Contact Lens
   When billing for a superficial keratectomy in which I remove corneal epithelium, polish with 57 blade and weck cell sponges, plus place a bandage contact lens, is the correct coding 65400 and 92071?
