Final answer:
The CPT® code for placement of two adjustable sutures during strabismus surgery involving horizontal muscles is 67335. This code is used for one or more muscles with adjustable suture placement and reported only once despite the number of sutures used.
Step-by-step explanation:
The CPT® code(s) reported for the placement of two adjustable sutures during strabismus surgery involving the horizontal muscles is 67335. This code represents strabismus surgery on the horizontal muscle (one or more muscles) with the placement of an adjustable suture(s). It's important to note that the code is used once regardless of the number of sutures used. Therefore, for two adjustable sutures, you would still report 67335 only once.
