Summary & Overview
CPT 0308T: Ocular Telescope Implantation for Macular Degeneration
CPT code 0308T covers a specialized ophthalmic surgical procedure: removal of the natural or previously implanted intraocular lens and implantation of an ocular telescope for patients with advanced age‑related macular degeneration. The procedure is device‑based and intended to improve central vision by enlarging the retinal image, making it clinically significant for a subset of patients with severe maculopathy who have limited alternatives.
Key payers in the national landscape include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare and Medicare. Coverage policies and medical necessity criteria vary across these payers, affecting prior authorization requirements, benefit design, and member out‑of‑pocket exposure.
Readers will find a concise overview of the clinical indication and typical sites of service, a summary of which major payers are included in the assessment, and guidance on the types of benchmarks and policy topics commonly reviewed for this procedure (coverage criteria, utilization trends, and coding/claim considerations). Data not available in the input will be identified where applicable; the report is intended to inform payers, providers, and policy analysts about the clinical and administrative context surrounding CPT code 0308T.
Billing Code Overview
CPT code 0308T describes the surgical removal of a patient’s natural lens or a previously placed intraocular synthetic lens and implantation of an ocular telescope for patients with advanced age–related macular degeneration. This procedure is intended to enlarge the perceived image and improve central vision in eligible patients.
-
Service type: Surgical implantation of an intraocular telescope (device-based ocular surgery)
-
Typical site of service: Ambulatory surgery center or hospital outpatient surgical setting
Clinical & Coding Specifications
Clinical Context
A typical patient is an elderly individual with advanced, bilateral age-related macular degeneration (AMD) and visually significant central vision loss despite optimal medical therapy and low-vision rehabilitation. The patient has dense cataract or a previously implanted intraocular lens (IOL) with poor central visual acuity attributable primarily to macular disease rather than media opacity. Ophthalmology evaluation includes a comprehensive history, best-corrected visual acuity, dilated fundus exam, optical coherence tomography (OCT) documenting macular degeneration changes, and low-vision assessment demonstrating potential benefit from image magnification. Preoperative clearance includes medical optimization, informed consent covering expected visual outcomes and potential complications, and measurement for appropriate ocular telescope implant sizing.
The clinical workflow: preoperative assessment and diagnostic testing; perioperative planning including discussion of risks and alternative low-vision devices; removal of the patient’s crystalline lens or explantation of a prior IOL; implantation of the ocular telescope device; routine immediate postoperative management in an ambulatory surgery center or hospital outpatient setting with topical and/or systemic medications; and scheduled follow-up visits for visual rehabilitation, device orientation, and monitoring for surgical complications such as elevated intraocular pressure or endophthalmitis.
Typical site of service: Ambulatory Surgery Center (ASC) or Hospital Outpatient Department. Service type: Surgical intraocular implantation procedure for advanced AMD aimed at magnifying retinal image size.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
00 | Unspecified — generally not used in CMS claims | Rarely used; included in raw modifier list but not typically applied to this procedure |
22 | Increased procedural services | Use when operative complexity or time substantially exceeds typical for ocular telescope implantation and documentation supports increased work |
23 | Unusual anesthesia — patient not medically stable for standard anesthesia | Use when general anesthesia or deep sedation is required due to medical condition and documentation supports use of modifier 23 per payer rules |
50 | Bilateral procedure | Use when both eyes undergo telescope implantation and payer allows bilateral reporting; follow payer-specific bilateral rules |
51 | Multiple procedures | Use when another distinct surgical procedure is performed during the same operative session in addition to the telescope implantation |
52 | Reduced services | Use when a substantial portion of the procedure is intentionally not performed or aborted with reduced service documentation |
53 | Discontinued procedure | Use when the procedure is started but discontinued due to extenuating circumstances; document reason for discontinuation |
62 | Two-surgeon technique | Use if two surgeons are required and both meet payer criteria for reporting two-surgeon services |
66 | Surgical team approach | Use when a surgical team is used and payer allows team reporting for the case |
78 | Return to OR for related procedure during global period | Use when a related operative procedure for a complication occurs during the global period and documentation ties it to the original surgery |
80 | Assistant surgeon | Use when an assistant at surgery is required and assistant surgeon services are reportable by payer |
81 | Minimum assistant surgeon | Use when a minimum assistant is required and payer recognizes modifier 81 |
82 | Assistant surgeon (when qualified resident surgeon not available) | Use when an assistant is required because a qualified resident is not available and documentation meets payer criteria |
TC | Technical component | Use when billing only the technical component of an associated diagnostic test or imaging study related to the procedure (if applicable) |
