What 67345 covers
An ophthalmologist, often a strabismus specialist, injects a chemodenervating agent into a selected extraocular muscle to reduce its activity temporarily. The treatment may be used for strabismus or diplopia when weakening a particular muscle is clinically appropriate. It is performed in an outpatient setting, including an office or procedure room, or in a facility setting.
Report 67345 for the chemodenervation procedure, rather than for surgical recession or resection of an eye muscle. The operative or procedure note should identify the treated muscle and eye, the indication, and the agent and dose administered. When the practice supplies the drug, report it separately under the applicable drug code when supported. CMS assigns a 10-day global period, so related postoperative visits during that period are included. For bilateral treatment, modifier 50 is paid at 150%. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and others at 50%. Assistant-at-surgery payment is restricted; co-surgeons and team surgery are not permitted.

- 67312 describes surgical recession or resection involving two horizontal muscles. It is not the code for weakening a muscle by injection.
- 67314Eye muscle surgery
- 67314 is for surgical recession or resection of one vertical muscle. 67345 describes chemodenervation, regardless of whether the selected muscle is horizontal or vertical.
67345 billing questions
When should 67345 be selected instead of an eye muscle surgery code?
Use 67345 when treatment is by chemodenervation injection to weaken an extraocular muscle. Use a recession or resection code when the surgeon surgically changes muscle position or length.
Can the supplied drug be billed separately?
The code reports the chemodenervation procedure. When the practice supplies the drug, report the applicable drug code separately when supported by the record.
How is bilateral treatment reported?
For bilateral treatment, report modifier 50; CMS pays the bilateral procedure at 150%.
Are postoperative visits separately payable during the global period?
Related postoperative visits during the 10-day global period are included in 67345.
Can an assistant surgeon or co-surgeon be reported?
CMS does not pay an assistant at surgery for this procedure. Co-surgeons and team surgery are not permitted.
What happens if another procedure is performed in the same session?
Under the standard multiple procedure reduction, the highest-valued procedure is paid in full and the other procedure or procedures are paid at 50%.
