Summary & Overview
CPT 92025: Corneal Curvature Measurement, Interpretation, and Report
CPT code 92025 represents a diagnostic ophthalmic service in which a provider measures the curvature of one or both corneas, interprets the measurements, and prepares a formal report. This procedure is commonly used to evaluate corneal shape for refractive assessments, contact lens fittings, and preoperative planning for ocular surgery. Nationally, accurate coding and documentation for this code support appropriate clinical decision-making and claims adjudication for eye care services.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of the code’s clinical context, typical sites of service, and common billing considerations. The publication summarizes available benchmarks where present, highlights relevant policy or coverage nuances from major payers, and explains how this procedure fits into broader ophthalmic diagnostic workflows.
The content is intended to inform coding professionals, clinicians, and policy analysts about the purpose and use of CPT code 92025, offering clear context for billing, reporting, and clinical interpretation without providing clinical guidance or individualized recommendations.
Billing Code Overview
CPT code 92025 describes measurement of the curvature of one or both corneas, interpretation of the findings, and preparation of a report. This service is a diagnostic ophthalmic procedure that assesses corneal shape and refractive properties to aid in clinical evaluation and management.
Service Type: Diagnostic ophthalmic measurement
Typical Site of Service: Ophthalmology clinic or optometry office, outpatient diagnostic setting
Clinical & Coding Specifications
Clinical Context
A 34-year-old patient presents to an ophthalmology clinic with complaints of progressive astigmatism and difficulty achieving satisfactory vision with glasses. The provider performs keratometry to measure corneal curvature of one or both eyes, documents the measurements, interprets the results relative to refraction and prior records, and prepares a report. Typical workflow: patient registration and visual acuity screening → history and indication documented by the provider (for example, refractive assessment, contact lens fitting, keratoconus screening, post-operative evaluation) → performance of keratometry using an automated keratometer or autorefractor-keratometer device → provider review and interpretation of steep and flat meridians, diopters, and axis → incorporation of findings into refractive plan, contact lens parameters, or surgical decision-making → report generation and inclusion in the medical record. Typical site of service is an outpatient ophthalmology clinic or optometry office; testing may also occur in ambulatory surgical centers for pre- or post-operative evaluations. Common patient scenarios include routine refractive assessment for spectacle or contact lens prescription, evaluation for toric intraocular lens planning, monitoring of corneal shape in keratoconus, and post-operative assessment after corneal or refractive surgery.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
25 | Significant, separately identifiable evaluation and management service by the same physician on the same day of the procedure | Use when a distinct E/M visit is performed in addition to keratometry and documented separately |
26 | Professional component | Use when reporting only the professional interpretation and report separate from the technical test |
TC | Technical component | Use when reporting only the technical component (equipment and technician) of the keratometry |
59 | Distinct procedural service | Use when keratometry is performed on the same day as another procedure that is not normally reported together and documentation supports distinctness |
52 | Reduced services | Use when the procedure is partially reduced or not completed as described in the full procedure description |
53 | Discontinued procedure | Use when keratometry is started but discontinued due to extenuating circumstances or patient intolerance |
76 | Repeat procedure by same provider (Note: 76 is not in the provided list; use 77/others if available) | Data not available in the input |
RT | Right side | Use when specifically identifying the right eye service when laterality reporting is required |
LT | Left side | Use when specifically identifying the left eye service when laterality reporting is required |
50 | Bilateral procedure | Use when both eyes are tested and payer requires a bilateral modifier rather than separate eye line items |
59 | Distinct procedural service | Duplicate entry removed in clinical use; see above for guidance |

H18.6 | Keratoconus | Serial keratometry is used to detect and monitor corneal steepening and progression |
H52.4 | Presbyopia | Keratometry may be part of preoperative measurements when planning refractive solutions for presbyopia |
