Summary & Overview
CPT 67332: Strabismus Repair for Scarred Extraocular Muscles
CPT code 67332 is an add-on procedural code used to document increased surgical complexity during strabismus repair when significant scarring from prior extraocular muscle surgery, retinal detachment repair, or thyroid-related myopathy is present. Nationally, accurate use of this code matters for clinical documentation, appropriate reimbursement for additional operative work, and tracking complexity in ophthalmic surgical care. Key payers in this review include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. This publication explains what 67332 represents, the clinical scenarios that trigger its use, and the typical settings where it is performed. Readers will find a concise clinical context for when the add-on applies, an overview of common payer coverage considerations, and guidance on documentation elements that support reporting the code. Also included are benchmarking topics and recent policy update highlights relevant to payers and hospital billing teams. Data not available in the input for specific ICD-10 pairings, payer-specific rules, or reimbursement benchmarks are noted as unavailable.
Billing Code Overview
CPT code 67332 is an add-on strabismus surgical procedure reported when scarring from prior extraocular muscle surgery, retinal detachment repair, or thyroid-associated myopathy increases the technical difficulty of realigning eye muscles. The code indicates that the surgeon performed additional work to address scar tissue that complicates reattachment or repositioning of the extraocular muscles.
Service type: Ophthalmic surgical add-on (strabismus repair in scarred tissue)
Typical site of service: Hospital outpatient operating room or ambulatory surgery center, where operative microscope and surgical ophthalmology support are available.
Clinical & Coding Specifications
Clinical Context
A 48-year-old patient with a history of prior strabismus surgery presents with a symptomatic, incomitant ocular misalignment and diplopia. Prior operative reports note scarring and adhesions of the extraocular muscles. On examination the patient has restricted motility and abnormal head posture. After conservative management fails, the ophthalmologist schedules a strabismus revision with planned dissection of scarred extraocular muscle tissue to restore alignment.
The clinical workflow: preoperative evaluation in the ophthalmology clinic with history, ocular motility measurements, and informed consent. On the day of surgery in an ambulatory surgery center or hospital operating room, general anesthesia is administered. The surgeon performs conjunctival dissection, identifies scarred extraocular muscle(s), performs careful adhesiolysis and muscle repositioning or resection as indicated. The add-on procedure code 67332 is reported in addition to the primary strabismus procedure when scarring from prior strabismus repair, retinal detachment surgery, or thyroid-related orbital myopathy increases surgical difficulty. Postoperative recovery includes immediate assessment of alignment, instructions for activity and follow-up visits to monitor motility and healing.
