CPT® Code 92015

Last Updated: February 2026 | Verified for 2026 AMA, CPT & CMS Guidelines

Quick Reference:

• What CPT 92015 means: Determination of refractive state (“refraction”)—the professional service of measuring refractive error (sphere/cylinder/axis, etc.) to generate or update a glasses or contact lens prescription. It is distinct from an ophthalmologic exam (e.g., 92004/92014) and distinct from diagnostic testing.
• Medicare Part B coverage (Original Medicare): Medicare excludes refraction from coverage regardless of the reason it is performed. CMS states that expenses for all refractive procedures are excluded. Claims are expected to deny as statutorily non-covered.
• Medicare billing modifiers: For a statutorily excluded service, CMS MLN guidance instructs use of modifier GY to indicate the item/service is excluded or not a Medicare benefit. Voluntary advance notice workflows may use GX/GY combinations when appropriate, but the coverage status does not change.
• Payer variability outside Medicare: Medicaid and commercial policies vary widely. Some Medicaid programs list 92015 as payable under a vision fee schedule, while others treat refraction as included in the exam and do not reimburse separately. Commercial medical plans often bundle refraction into the eye exam; separate vision plans are the most common payer pathway for a covered refraction.
• Modifiers that do not apply: 92015 has no technical component, so TC/26 are not valid. It is not an E/M service, so modifier 25 does not belong on 92015. AMA guidance on modifier 25 is limited to E/M services and should be applied only to an E/M code when separately supported—not to refraction.
• Documentation that payers and auditors expect: Record the objective refraction result (or prescription values), method (manifest/autorefraction, trial lens refinement), and the clinical context (e.g., decreased visual acuity, new prescription request, postoperative refractive endpoint). Missing or non-specific “refraction performed” documentation is a common audit failure.
• Bundling is the main commercial denial driver: Many medical policies consider refraction integral to a routine eye exam and deny separate reporting. Postoperative refractions (e.g., after cataract surgery) are commonly patient-pay under Medicare and often bundled by commercial payers unless a vision benefit applies. CPT 92015 is simple in concept but frequently problematic in reimbursement because refraction sits at the boundary between medical eye care and routine vision services.

Most denials and audit exposure come from three preventable issues:

• billing Medicare Part B for a service CMS explicitly excludes,
• billing a medical payer when the plan bundles refraction into the eye exam (or expects it under a separate vision benefit), and
• incomplete documentation that fails to show an actual refractive determination and outcome. This 2026-focused guide follows CMS policy and high-authority payer guidance to help you code, bill, and document 92015 in a way that is realistic for denials, defensible for audits, and consistent across payers.

1. CPT 92015 Definition and Procedure Scope

CPT 92015 reports determination of refractive state—the professional service of measuring a patient’s refractive error to establish or update a prescription for corrective lenses. Operationally, it encompasses the clinical work needed to determine final refractive values (e.g., sphere/cylinder/axis, add power), typically through manifest refraction techniques (phoropter/trial lenses) and often supported by autorefraction as a starting estimate. It is a professional service, not a technical imaging test, and it is separate from the evaluation components of an ophthalmologic exam.

Importantly, 92015 is not the eye exam. Many visits include both (a) an ophthalmologic exam code (intermediate/comprehensive) and (b) a refraction. Whether a payer allows both depends on benefit design and bundling policy. Some medical policies explicitly restrict who may bill 92015 (for example, limiting reporting to an MD/DO or optometrist), underscoring that refraction is treated as a clinician-performed service rather than a delegated technical test.

No technical component: Refraction does not split into professional/technical components, so -26 and -TC are invalid. If a clinic uses an autorefractor device, that does not convert 92015 into a technical test; the billable service remains the professional determination of refractive state and the resulting prescription.

Practical boundary (what auditors look for): If your note does not show a refractive endpoint (prescription or measured refractive values) and instead contains only “refraction done,” payers can conclude the billed service is not supported. Make it easy to find: record the final refraction and the reason it was performed.

2. Medicare, Medicaid, and Commercial Coverage Rules

2.1 Medicare Part B (Original Medicare): excluded by policy

For Medicare Part B, refraction is a long-standing general exclusion. CMS’s Medicare Benefit Policy Manual states that expenses for all refractive procedures are excluded from coverage, without regard to the reason the refraction is performed and regardless of whether it is performed by an ophthalmologist or optometrist. In practice, this means CPT 92015 is expected to deny as statutorily non-covered under Original Medicare.

Clinically, this includes refractions performed for routine prescription updates, decreased vision, postoperative lens prescription changes, or refractive endpoints after surgery. The exclusion is about the service category, not about medical necessity documentation. Even excellent documentation does not convert 92015 into a covered Medicare benefit.

2.2 Medicare billing workflow: GY (and when notices are used)

Because the service is excluded, the clean billing signal is modifier GY, which indicates that the item/service is statutorily excluded or does not meet the definition of any Medicare benefit. CMS MLN guidance on advance written notices and claim modifiers explains using GY for statutorily excluded services and distinguishes it from situations where an ABN is used for potentially covered services that may not be medically necessary in a specific case.

CMS transmittal guidance on GA/GX/GY/GZ modifiers reinforces that GY is the statutory exclusion indicator and explains how it differs from GA (ABN on file for “not reasonable and necessary” denials). In other words: for 92015, the compliance logic is “excluded benefit,” not “medically unnecessary.”

Scenario 1: Medicare Part B patient requests a glasses prescription update

Setting: Ophthalmology or optometry office.

Service: Refraction performed; new prescription provided.

Coverage result: 92015 is excluded under Medicare Part B and should be treated as patient-pay (or billed to a vision benefit if present). CMS policy excludes refraction regardless of why it is performed.

Claim hygiene: If you submit to Medicare at the patient’s request, append GY consistent with CMS guidance for excluded services.

2.3 Medicare Advantage: plan benefit design matters

Medicare Advantage (MA) plans must cover Medicare Part A/B benefits, but many offer supplemental vision benefits. The key operational rule is: do not assume 92015 is separately reimbursable just because the patient is enrolled in MA. Some MA products treat refraction as part of a supplemental vision package, while others mirror Original Medicare’s exclusion. When a plan covers routine refraction, it is usually under the plan’s vision benefit rules rather than medical necessity logic.

Because MA plan rules vary substantially, the defensible process is to verify whether the member’s plan includes routine refraction coverage, and whether the plan expects billing under a vision vendor or a specific claim pathway. When MA policies incorporate language similar to Original Medicare exclusions, they typically deny 92015 unless the supplemental vision benefit is active and billed correctly.

2.4 Medicaid: state-by-state variability (and why your “neighbor state” rule fails)

Medicaid vision benefits are state-administered and often delegated to managed care organizations; coverage and reimbursement rules for refraction vary. Some programs list CPT 92015 explicitly on vision/optometry fee schedules, signaling that the service is payable when coverage criteria and frequency limits are met. North Carolina’s Medicaid schedule is an example of a state document listing payable vision services used operationally by providers.

Other states treat refraction as included in the comprehensive eye exam service and do not reimburse 92015 separately. Louisiana Medicaid policy materials illustrate how state guidance may designate refraction as bundled into exam services for payment purposes.

Medicaid compliance point: For state Medicaid, the question is rarely “is refraction medically necessary?” and more often “is it a covered benefit for this age group, on this interval, under this benefit category, and does the state pay it separately or bundle it into the exam?” Use the state’s controlling fee schedule/manual first.

2.5 Commercial medical plans vs standalone vision plans

Commercial medical insurers commonly treat refraction as a routine vision service and may bundle it into the ophthalmologic exam or deny it as non-covered under the medical benefit. Many organizations cover routine refraction through a standalone vision plan instead (e.g., vision vendor networks), frequently allowing one refraction per benefit year.

Medical policy language often states that if refraction is part of a routine eye visit, 92015 is not separately billable. Blue Cross Blue Shield of Michigan’s refractive state policy is an example of a payer document used by providers to understand when 92015 may be separately reported versus bundled.

3. ICD-10-CM Diagnosis Coding That Fits Refraction Encounters

Diagnosis coding for 92015 depends on payer context and encounter purpose. In general, link the refraction to either (a) a documented refractive condition or (b) an exam encounter when the service is a routine vision assessment. The goal is not to “force coverage” (particularly not for Medicare, where refraction is excluded), but to ensure the record and the claim tell the same story.

3.1 Common ICD-10-CM categories

• Refractive disorders (H52.-): Use the most specific refractive error code available (e.g., hyperopia, myopia, astigmatism, presbyopia). These codes describe the refractive diagnosis that the refraction measures and corrects.
• Routine eye exam encounters (Z01.-): Use encounter codes when the visit is primarily an exam without a specific refractive diagnosis being emphasized in the assessment (for example, preventive or routine vision exam documentation patterns).
• Lens-related context: Postoperative and lens status codes may appear in the record for context, but they do not override Medicare’s refraction exclusion. Use them when they truthfully describe patient status and are relevant to the visit assessment. When billing a commercial vision plan, claims systems may have plan-specific diagnosis expectations (often allowing routine exam diagnoses) because the service is a routine vision benefit. When billing state Medicaid, follow state program rules for required diagnoses and whether pediatric vs adult benefit rules apply. For Medicare, remember: diagnosis choice does not make 92015 payable. CMS policy excludes the service category.

Scenario 2: Vision plan refraction for myopia progression

Setting: Optometry clinic; patient covered by a standalone vision plan.

Service: Refraction with prescription update due to decreased distance visual acuity.

Diagnosis approach: Use the appropriate refractive disorder code (H52.- category) consistent with documentation. Why it matters: Vision plans typically cover refraction under routine benefits; accurate diagnosis supports audit and benefit rules even when coverage is not “medical necessity” based.

4. Modifier Rules (GY/GX/GA) and Common Modifier Errors

4.1 Medicare: GY is the key modifier for excluded refraction

For Medicare claims submitted for statutorily excluded services, CMS MLN guidance indicates that modifier GY communicates “excluded or not a Medicare benefit.” This is the correct mechanism to prevent confusion with medical necessity denials (which would involve different modifiers and ABN logic).

CMS transmittal guidance on GA/GX/GY/GZ further clarifies that GY is used when a supplier wants to indicate statutory non-coverage or non-benefit status, while GA relates to ABN-driven denials for items/services expected to be denied as not reasonable and necessary. For refraction, the compliance frame is statutory exclusion—not ABN-based medical necessity.

4.2 Modifier 25: apply only to an E/M code (not to 92015)

Incorrect modifier usage is a frequent audit trigger. Modifier 25 does not apply to 92015 because 92015 is not an E/M service. AMA guidance on modifier 25 states it is appended to E/M service codes when a significant, separately identifiable E/M service is performed on the same day as another procedure or service. If an E/M (or ophthalmologic exam code, as applicable under payer rules) is separately supported, modifier 25—when appropriate—belongs on the E/M service code, not on 92015.

4.3 TC/26 are invalid; laterality is payer-specific

Because refraction has no technical/professional split, TC and 26 are invalid. Laterality modifiers (RT/LT) are rarely the deciding factor for refraction payment because refraction is ordinarily determined binocularly and results in a bilateral prescription, but some payer systems may still require internal modifier conventions. Follow the payer’s specific claim rules if they require RT/LT formatting; do not invent component modifiers that do not apply.

High-risk modifier pattern: Adding modifier 25 to 92015, or adding TC/26 to 92015, is easy for payers to detect and often signals that billing rules were not understood. Clean claims avoid these modifiers entirely on 92015.

5. Frequency Limits, Benefit-Year Rules, and When Extra Refractions Are Risky

For payers that do cover refraction (primarily vision plans and some Medicaid programs), frequency limits are common. These limits are usually expressed as one refraction per benefit year or at defined intervals, sometimes varying by age (e.g., pediatric annual schedules vs adult schedules). The compliance risk here is not “medical necessity” in the Medicare sense; it is benefit exhaustion and repeated refraction billing without documentation showing why an additional refraction was clinically required.

Medicaid programs may place frequency rules in fee schedules, manuals, or managed care policies. For example, when a state lists 92015 in a fee schedule, it commonly implies that the service is payable under the vision benefit structure and is subject to program limits.

Commercial vision plans may require that refraction be performed by credentialed providers and may limit refractions to specific intervals unless a documented exception is present (e.g., rapid refractive change, specific pediatric needs, or post-surgical refractive stabilization checks under plan rules). Where a payer allows exceptions, your chart should explicitly document: (1) interval since last refraction, (2) the patient’s symptom or functional change, and (3) the measured refractive change that justified the additional service.

6. Bundling and Same-Day Reporting (92004/92014, postoperative, and “routine” visits)

Bundling is the most common reason 92015 “doesn’t pay” for commercial medical plans. Many policies treat refraction as a routine component of an eye exam when performed as part of that visit. A payer may permit billing an ophthalmologic exam code but deny the refraction as included, especially when the visit is a routine vision check.

6.1 Routine ophthalmologic exams and refraction

When a refraction is performed during a routine eye exam, some medical policies explicitly state that 92015 cannot be reported separately. In practice, this means:

• If you are billing a medical plan for a routine exam, the refraction may be bundled or non-covered per medical policy.
• If the patient has a vision plan, the refraction may be covered and reported under the vision benefit with plan-specific rules. Blue Cross Blue Shield of Michigan’s refractive policy language is an example of guidance that providers use to determine whether separate reporting is allowed or considered incidental when refraction is part of a routine visit.

6.2 Postoperative refraction (including cataract-related endpoints)

Postoperative refraction after cataract surgery is a classic source of billing confusion. Two distinct concepts often get conflated:

• Corrective eyewear coverage after cataract: Medicare has separate rules for certain eyewear after cataract surgery.
• Refraction as a service: CMS states refraction is excluded from coverage. That exclusion applies even when refraction is performed after surgery to finalize a glasses prescription. Commercial policies may also bundle postoperative refractions into a surgical package or treat them as routine vision services. Operationally, many practices manage postoperative refraction as patient-pay unless a vision benefit covers it.

Scenario 3: Cataract postoperative visit and “final glasses prescription” request

Setting: Ophthalmology postoperative care.

Service: Refraction performed to finalize prescription.

Medicare Part B: Refraction remains excluded; coverage does not convert because the refraction is performed postoperatively.

Best practice: Treat as patient-pay or bill through a vision benefit when applicable; document refractive endpoint and purpose.

7. Audit Triggers and Documentation Standards (What to Put in the Chart)

Although many 92015 claims deny for coverage reasons, audits still occur—particularly in high-volume vision environments and in payer contexts where refraction is covered (vision plans, some Medicaid programs). Auditors generally focus on whether the service was actually performed, whether it was billed to the correct benefit, and whether modifier usage indicates correct understanding of coverage rules.

7.1 Common audit triggers

• Billing Medicare for refraction as though it were covered: Submitting 92015 without understanding CMS’s exclusion is a predictable denial and a compliance red flag if patterns suggest systematic billing errors. CMS policy explicitly excludes refraction regardless of reason.
• Modifier misuse: The highest-yield errors are appending -25 to 92015 or using TC/26. AMA guidance on modifier 25 supports that it belongs on E/M services only, when separately identifiable and documented.
• Bundling conflicts: Billing 92015 to a medical plan that bundles refraction into the exam often produces denials and can trigger post-payment review if the payer believes separate refraction billing is being used to increase reimbursement in routine visits.
• Insufficient documentation of the refractive determination: Records that lack final refraction values/prescription, do not show the work performed, or do not show why the refraction was needed are vulnerable—particularly when frequency limits are exceeded.

7.2 Documentation checklist (audit-resistant)

To support 92015 in any payer environment where it is billable (or when a patient-pay service must be documented properly), include:

• Reason for refraction: Patient request for updated prescription, decreased visual acuity, refractive change suspicion, postoperative endpoint determination, occupational requirement, etc.
• Method: Manifest refraction performed; whether autorefraction was used as a starting point; any trial lens refinement or special circumstances.
• Objective results: Final refraction values and/or the issued prescription (OD/OS, sphere/cylinder/axis, add, prism if applicable).
• Outcome: Visual acuity achieved with correction (best-corrected VA) when clinically relevant.
• Provider identification: The clinician responsible for the refractive determination, consistent with payer eligibility rules. Documentation reality: “Refraction performed” without a refractive endpoint is often treated as not performed for payment and audit purposes. Build a standardized template field for final refraction values to prevent avoidable denials.
