Summary & Overview
CPT 67312: Strabismus Repair with Muscle Recession or Resection
CPT code 67312 represents a corrective ophthalmic surgery—strabismus repair—where an ophthalmologist performs a recession or resection of extraocular muscles to realign the eye. This code is used to report surgical correction of ocular misalignment and is clinically important because strabismus surgery can restore binocular function, reduce diplopia, and improve cosmetic appearance. Nationally, utilization of surgical eye muscle procedures affects surgical capacity in ambulatory surgical centers and hospitals and influences coverage and prior authorization practices among major payers.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find concise clinical context about the procedure and typical sites of care; a summary of common billing modifiers provided in the input; and guidance on areas that commonly affect coding and claims (for example, laterality, staged procedures, and bilateral versus unilateral reporting). The publication also outlines benchmarking topics and policy areas payers often address, such as coverage criteria, medical necessity documentation, and post-operative global period considerations.
This summary is intended for national audiences including clinicians, coding professionals, and policy analysts who need a clear, practical overview of what CPT code 67312 represents, who pays for it, and the key coding and policy topics to consider when handling related claims.
Billing Code Overview
CPT code 67312 describes a strabismus repair procedure in which the surgeon performs either a recession (weakening) or resection (strengthening) of extraocular muscles to realign the eye and correct ocular misalignment. This procedure is focused on repairing or adjusting the position and function of the eye muscles to improve ocular alignment and binocular vision.
Service type: Ophthalmologic surgical procedure — strabismus surgery
Typical site of service: Ambulatory surgical center or hospital operating room, with care provided by an ophthalmologist trained in strabismus surgery. If performed in an outpatient setting, same-day surgical recovery is common.
Clinical & Coding Specifications
Clinical Context
A 7-year-old child presents to a pediatric ophthalmology clinic with an identifiable horizontal esotropia causing diplopia and amblyopia risk despite prior conservative measures (occlusion therapy and corrective lenses). After comprehensive evaluation including ocular motility exam, binocular function testing, and preoperative anesthesia assessment, the surgeon schedules a strabismus repair under general anesthesia. In the operating room the ophthalmic surgeon performs a rectus muscle recession of the tight medial rectus and a resection of the lateral rectus to realign the ocular axes. Intraoperative adjustments to muscle placement are performed to obtain proper alignment. The typical workflow includes preoperative consent, anesthesia induction (usually general for pediatric patients), sterile prep, surgical muscle weakening (recession) or strengthening (resection), intraoperative assessment of alignment, closure, and postoperative recovery with ophthalmic follow-up to monitor alignment and visual rehabilitation.
