CPT 68320: Conjunctival Repair/Grafting for Conjunctivochalasis

CPT code 68320 represents surgical repair of the conjunctiva using autologous conjunctival tissue, performed to correct disorders such as conjunctivochalasis. This ophthalmic procedure restores normal conjunctival anatomy to relieve pain, irritation, and tear-film disruption. Nationally, accurate coding of conjunctival repair affects procedural reporting, quality monitoring in ophthalmology, and appropriate facility and professional fee assignment.

Key payers included in this analysis are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical description, typical sites of service, and commonly applied modifiers. The publication summarizes billing context and coding considerations relevant to surgical ophthalmology practices and facility billing teams.

The piece provides benchmarks and policy-relevant notes where available, clarifies the clinical indications tied to the code, and outlines what information is missing from the input. Data not available in the input includes associated taxonomies, specific ICD-10 diagnoses, related codes, and service-line detail beyond the procedural description.

Billing Code Overview

CPT code 68320 describes a surgical repair of the conjunctiva using the patient’s own conjunctival tissue as a graft or by rearranging existing conjunctival tissue. The procedure addresses conditions such as conjunctivochalasis, which involves excess conjunctival folds that can cause irritation, tearing, and pain.

Service type: Surgical ophthalmic procedure — conjunctival repair/grafting

Typical site of service: Ambulatory surgical center or hospital outpatient department; occasionally performed in an ophthalmic specialty clinic with surgical capability

Clinical & Coding Specifications

Clinical Context

A 68-year-old patient presents to an ophthalmology clinic complaining of ocular irritation, foreign body sensation, intermittent tearing, and localized conjunctival folds that worsen with blinking. Slit-lamp examination confirms symptomatic conjunctivochalasis with redundant conjunctival tissue causing tear film disruption and focal keratopathy. After conservative measures (lubrication, topical anti-inflammatories) fail, the ophthalmic surgeon schedules a surgical repair using autologous conjunctival tissue rearrangement or conjunctival autograft to excise and repair the redundant tissue.

The clinical workflow includes preoperative evaluation with ocular history, vision testing, corneal staining, and informed consent. On the day of service, the procedure is performed in an ambulatory surgical center (ASC) or outpatient ophthalmic operating room under local or monitored anesthesia care. The surgeon excises redundant conjunctiva, mobilizes local conjunctival tissue or harvests a conjunctival autograft, and secures it with sutures or tissue adhesive. Postoperative care includes topical antibiotics and steroids, activity restrictions, and follow-up visits for suture removal and assessment of symptom resolution. Typical sites of service are outpatient ophthalmology clinics, ambulatory surgical centers, or hospital outpatient departments.

Coding Specifications

Modifier	Description	When to Use
`25`	Significant, separately identifiable evaluation and management service by the same physician on the day of a procedure	Use when a separate E/M visit is provided on the same day as the surgical repair and documentation supports a distinct evaluation.
`22`	Increased procedural services	Use when work required to perform the repair is substantially greater than typical and documentation explains the reasons and additional work.
`52`	Reduced services	Use when the procedure is partially reduced or not completed as planned and documentation explains the reduction.
`53`	Discontinued procedure	Use when the procedure is started but discontinued due to extenuating circumstances or patient condition.
`59`	Distinct procedural service	Use when another procedure performed on the same day is not normally reported together and documentation supports distinctness.
`62`	Two surgeons	Use when two surgeons work together as primary surgeons performing distinct portions of the conjunctival repair.
`66`	Surgical team	Use when a surgical team (separate from two surgeons) provides the procedure in a team setting.
`76`	Repeat procedure by same physician	Use when the same physician repeats the procedure subsequent to the initial service (if clinically appropriate).
`77`	Repeat procedure by another physician	Use when another physician repeats the procedure on the same patient.
`RT`	Right side	Use to identify the right eye when billing laterality for the conjunctival repair.
`LT`	Left side	Use to identify the left eye when billing laterality for the conjunctival repair.
