Summary & Overview
CPT 65756: Full‑Thickness Corneal Transplant for Endothelial Replacement
CPT code 65756 denotes a full-thickness corneal transplant (penetrating keratoplasty) performed to replace a damaged corneal endothelium. This surgical procedure is a key treatment option for advanced corneal endothelial disease that compromises vision and corneal clarity. As a nationally recognized CPT code, 65756 is relevant to ophthalmic surgeons, hospital billing departments, ambulatory surgical centers, and payers managing coverage for complex anterior segment surgeries.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of clinical context for corneal transplantation, typical sites of service, and common billing considerations associated with this procedure. The publication also outlines benchmarks and payer coverage patterns, summarizes relevant policy updates affecting corneal transplant authorization and coverage, and explains coding nuances that can influence reimbursement and claim adjudication.
This summary equips clinicians, coding professionals, and policy analysts with concise information on the clinical purpose of CPT code 65756, where the procedure is typically performed, and which major payers commonly cover it. Data not available in the input is noted where applicable.
Billing Code Overview
CPT code 65756 describes a full-thickness corneal transplant performed to replace a damaged corneal endothelium. The procedure involves removing the recipient's diseased corneal tissue and transplanting a donor cornea to restore corneal clarity and visual function.
-
Service type: Surgical procedure — full-thickness corneal transplantation (penetrating keratoplasty) for endothelial disease
-
Typical site of service: Hospital operating room or ambulatory surgical center where ophthalmic surgical procedures are performed
Clinical & Coding Specifications
Clinical Context
A 68-year-old patient with progressive corneal endothelial decompensation from pseudophakic bullous keratopathy presents with decreasing vision, glare, and pain in the affected eye. After ophthalmic evaluation including visual acuity, slit-lamp exam, pachymetry, endothelial cell count, and corneal topography, the corneal specialist determines the patient is a candidate for a full-thickness corneal transplant to replace the damaged endothelium and restore corneal clarity. The typical clinical workflow includes preoperative assessment and clearance, scheduling in an ambulatory surgery center or hospital outpatient department, preoperative marking and anesthesia (local with monitored anesthesia care or general anesthesia for select patients), donor cornea preparation, trephination of host cornea, replacement with donor corneal button, suturing, and immediate postoperative medications and instructions. Postoperative follow-up occurs frequently in the first month to monitor graft clarity, intraocular pressure, suture management, and rejection surveillance, with additional visits for suture removal and long-term graft care.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
26 | Professional component | Use when billing only the physician’s portion of a split service where technical component billed separately. |
50 | Bilateral procedure | Use when the same corneal transplant is performed on both eyes during the same operative session. |
51 | Multiple procedures | Use when additional qualifying procedures are performed in the same session and multiple-procedure rules apply. |
52 | Reduced services | Use when the procedure is partially reduced or not completed as originally planned. |
53 | Discontinued procedure | Use when the procedure is started but terminated due to extenuating circumstances. |
59 | Distinct procedural service | Use when another procedure performed at the same session is separate and distinct from the transplant.</n |
66 | Surgical team | Use when a surgical team performs the procedure (team approach) per payer rules. |
78 | Return to OR for related procedure during postoperative period | Use when patient returns to the operating room for a complication related to the original transplant. |
79 | Unrelated procedure during postoperative period | Use when an unrelated procedure is performed during the global period. |
80 | Assistant surgeon | Use when an assistant surgeon participates in the procedure. |
81 | Minimum assistant surgeon | Use when a minimal assistant surgeons involvement is documented. |
82 | Assistant surgeon (unusual circumstances) | Use when the assistant is required due to patient condition or unusual complexity. |
76 | Repeat procedure by same physician | Use when the same physician repeats the transplant procedure later the same day. |
| Taxonomy Code | Specialty | Notes |
|---|---|---|
| 208SX0200X | Ophthalmology | Corneal surgeons and anterior segment specialists who perform corneal transplantation. |
| 207W00000X | Ophthalmic Plastic and Reconstructive Surgery | Surgeons who may manage complex anterior segment reconstruction although less commonly primary for endothelial transplants. |
| 207L00000X | Optometry | Provides pre- and postoperative refractive and visual rehabilitation support (scope varies by state). |
| 208D00000X | Ocular Oncology (if involved) | Rarely involved when corneal pathology intersects with malignancy or complex ocular surface disease. |
Related Diagnoses
| ICD-10 Code | Description | Clinical Relevance |
|---|---|---|
H18.50 | Unspecified corneal edema, unspecified eye | Corneal edema from endothelial failure that may require full-thickness transplant when severe. |
H18.52 | Bullous keratopathy, unspecified eye | Common indication for corneal transplantation due to endothelial cell loss after cataract surgery or intraocular surgery. |
H18.8 | Other corneal disorders | Includes scarring, dystrophies, or degenerations that may necessitate penetrating keratoplasty. |
H16.9 | Keratitis, unspecified | Severe or chronic keratitis with stromal damage can progress to scarring and decompensation requiring transplant. |
H18.1 | Keratoconus | Advanced keratoconus with scarring or hydrops may require full-thickness graft when other interventions fail. |
Z94.7 | Corneal transplant status | Postoperative code indicating patient has a corneal transplant; used for follow-up and complication monitoring. |
T86.29 | Other complications of transplanted organ and tissue | Used when documenting graft rejection or failure requiring further intervention. |
