Common Ophthalmology CPT Codes for Billing and Coding

Last Updated on July 31, 2026

Ophthalmology is one of the most important procedures and test‑intensive specialties in medicine. In a single day, an ophthalmology practice may perform comprehensive eye examinations, optical coherence tomography (OCT), visual field testing, fundus photography, intravitreal injections, laser procedures, and major surgeries such as cataract extraction or retinal repair. 

Each of these services maps to specific CPT codes with distinct documentation, medical necessity, and payer rules. When coding is accurate, reimbursement reflects the complexity and volume of care. When coding is inconsistent, practices face denials, downcoding, and audit exposure on some of their highest‑volume services.

This guide provides a practical overview of the most common CPT codes, how they are organized, and how to apply them correctly in ophthalmology billing and coding.

How Ophthalmology CPT Codes Are Organized

Most ophthalmology services fall into a few well‑defined CPT ranges.

• 92002–92014 – Ophthalmological services (new and established patients, intermediate and comprehensive).
• 99202–99215 – Standard E/M codes, used by some payers instead of 920xx for eye visits.
• 921081-92287 – Diagnostic imaging and special tests (OCT, visual fields, photos, angiography, biometry).
• 65091–68899 – Surgery codes for the eye and ocular adnexa (CPT surgery section).
• 67005–67227 – Posterior segment procedures, including vitrectomy, retinal repairs, and intravitreal injections.

Understanding this structure helps coding teams quickly locate the right code family and then apply the correct payer rules, NCCI edits, and modifier requirements. It also clarifies why certain codes cannot be billed together and why selecting the correct code requires more than identifying the general type of examination, test, or procedure performed.

Ophthalmology E/M and Eye Visit Codes

Ophthalmology practices commonly use two parallel sets of codes for patient visits: ophthalmological service codes in the 920xx family and standard office and outpatient E/M codes in the 992xx family.

Ophthalmological Service Codes

92002 – New patient, intermediate ophthalmological service

Represents an intermediate evaluation of the visual system for a new patient.

92004 – New patient, comprehensive ophthalmological service

Covers a comprehensive visual-system examination for a new patient, along with the initiation of a diagnostic or treatment program.

92012 – Established patient, intermediate ophthalmological service

Applies to an intermediate visual-system evaluation for an established patient.

92014 – Established patient, comprehensive ophthalmological service

Captures a comprehensive examination for an established patient with the initiation or continuation of a diagnostic or treatment program.

These codes are specific to eye care and include evaluation of the visual system, with history, examination, and medical decision-making tailored to ophthalmology.

Office and Outpatient E/M Codes

The 992xx family follows current E/M guidelines and is selected according to medical decision-making or total time.

CPT Code	Description
99202	Reflects a new-patient visit supported by straightforward medical decision-making or the applicable time.
99203	Corresponds to a new-patient visit involving low-complexity medical decision-making or the applicable time.
99204	Describes a new-patient visit supported by moderate-complexity medical decision-making or the applicable time.
99205	Captures a new-patient visit involving high-complexity medical decision-making or the applicable time.
99211	Represents a minimal established-patient service that may not require the presence of a physician or other qualified professional
99212	Applies to an established-patient visit supported by straightforward medical decision-making or the applicable time.
99213	Covers an established-patient visit involving low-complexity medical decision-making or the applicable time.
99214	Reflects an established-patient visit supported by moderate-complexity medical decision-making or the applicable time.
99215	Describes an established-patient visit involving high-complexity medical decision-making or the applicable time.

Some Medicare Administrative Contractors and commercial payers allow 920xx codes for eye-specific visits, while payer requirements and contractual policies may influence whether 920xx or 992xx is appropriate for a particular encounter.

Documentation must support the selected code family. For 920xx services, the medical record should support the requirements of an intermediate or comprehensive ophthalmological examination. For 992xx services, documentation must meet the current E/M requirements for medical decision-making or time.

Diagnostic Testing CPT Codes in Ophthalmology

Diagnostic testing represents a significant portion of ophthalmology revenue and is also a frequent audit target. Each test has specific CPT, documentation, medical necessity, and interpretation requirements.

OCT and Imaging

92133 – Optical coherence tomography of the optic nerve: 

Captures computerized imaging of the optic nerve with interpretation and report.

92134 – Optical coherence tomography of the retina: 

Covers computerized retinal imaging, including evaluation of the macula, with interpretation and report.

These codes are commonly associated with conditions such as glaucoma, macular degeneration, diabetic retinopathy, diabetic macular edema, and other retinal or optic nerve disorders. Documentation should include the medical indication, images obtained, and a signed interpretation that explains findings and how they affect management. 

Visual Field Testing

Visual field codes are classified according to the extent and complexity of the examination.

CPT Code	Testing Level	Description
92081	Visual field, screening	Reports a limited visual field examination with interpretation and report.
92082	Visual field, limited	Represents an intermediate visual field examination with interpretation and report.
92083	Visual field, full/perimetry	Captures an extended visual field examination with interpretation and report.

The level selected should match the testing methodology and complexity actually performed. The record should document the indication, type of examination, findings, interpretation, and effect on the clinical plan.

Photography and Angiography

92250 – Fundus photography

Documents retinal photography with interpretation and report.

92235 – Fluorescein angiography

Evaluates retinal circulation and vascular abnormalities through fluorescein imaging with interpretation and report.

92240 – Indocyanine green angiography 

Assesses choroidal circulation through indocyanine green imaging with interpretation and report.

Medical necessity must be clear, and the report should describe the findings and their clinical implications rather than merely confirm that images were obtained.

When photography, angiography, or other imaging tests are performed during the same encounter, coding teams should review current NCCI edits and payer policies to determine whether each service is separately reportable.

Biometry and Other Tests

CPT Code	Ophthalmic Test	Description
92100	Serial tonometry	Tracks intraocular pressure through repeated measurements over an extended period.
92132	Anterior-segment imaging	Examines anterior structures such as the cornea, iris, chamber, or angle through computerized imaging.
92283	Color vision testing	Provides an extended assessment of color vision with interpretation and report.
92284	Dark adaptation testing	Evaluates the eye’s ability to adjust to reduced illumination with interpretation and report.

Biometry is typically performed in preparation for cataract surgery and must be documented as part of surgical planning. Other tests like anterior segment OCT, color vision, and dark adaptation have specific indications and should be ordered and interpreted in the context of the patient’s condition.

Frequently Billed Ophthalmology Procedure CPT Codes

Ophthalmology procedures range from minor in-office treatments to complex surgeries. 

Injections and Intravitreal Therapies

67028 – Intravitreal injection of a pharmacologic agent

This code covers the injection procedure itself, not the drug. Anti‑VEGF agents, steroids, and other intravitreal medications are billed separately with applicable J‑codes and units. Documentation should include the drug name, dose, lot number, laterality, and injection technique, along with the indication (e.g., wet AMD, diabetic macular edema, retinal vein occlusion). 

The procedure and drug lines should be reviewed together to ensure that laterality, diagnosis linkage, dosage, and billing units are consistent.

Lasers and Minor Procedures 

While many laser and minor procedure codes exist, some commonly used examples include: 

• 65435 – Removal of corneal epithelium

Covers removal of the corneal epithelium, with or without chemocauterization.

• 65800 – Anterior chamber paracentesis

Describes removal of aqueous fluid from the anterior chamber.

• 65820 – Goniotomy

Represents an angle-based procedure performed to improve aqueous outflow.

Each of these requires clear documentation of indication, technique, laterality, and any additional procedures performed during the same session. 

Retinal Detachment Repair Codes

Retinal detachment codes vary according to the repair technique performed.

CPT Code	Description
67105	Captures retinal detachment repair performed through photocoagulation
67107	Represents retinal detachment repair primarily involving scleral buckling
67108	Covers retinal detachment repair involving vitrectomy and related repair techniques
67110	Describes retinal detachment repair through the injection of air or gas
67113	Applies to complex retinal detachment repair involving vitrectomy and advanced techniques

The selected code must correspond to the procedure documented in the operative report. Indication, laterality, retinal findings, repair method, and any additional procedures should be clearly recorded.

Because these codes may have global periods and NCCI relationships with other retinal procedures, coding teams should review the complete operative report before claim submission.

Cataract and Lens Procedures

Cataract coding distinguishes between routine and complex surgery as well as procedures involving secondary or replacement intraocular lenses.

• 66982 – Complex cataract extraction with intraocular lens implantation

Captures cataract surgery requiring qualifying devices, techniques, or circumstances beyond a routine procedure.

• 66984 – Routine cataract extraction with intraocular lens implantation

Represents standard cataract removal with placement of an intraocular lens.

• 66985 – Secondary intraocular lens implantation

Covers insertion of an intraocular lens when cataract extraction is not performed during the same session.

• 66986 – Exchange of an intraocular lens 

Describes removal and replacement of an existing intraocular lens.

• 66987 – Complex cataract extraction with intraocular lens implantation and endoscopic cyclophotocoagulation

Combines complex cataract surgery with an endoscopic glaucoma procedure.

Cataract codes distinguish between routine and complex cases, with complex cataract requiring additional documentation (e.g., dense cataract, weak zonules, prior trauma, or other factors that increase difficulty). 

Glaucoma and Other Surgeries

• 65850 – Represents trabeculotomy performed through an external approach
• 66170 – Describes trabeculectomy when significant scarring from previous ocular surgery or trauma is not present.
• 66172 – Covers trabeculectomy performed when scarring from previous ocular surgery or trauma is present.
• 66180 – Captures insertion of an aqueous drainage device connected to an extraocular reservoir.

Glaucoma surgeries often require prior authorization and strong documentation of medical necessity. The record should include previous treatment, intraocular pressure trends, disease severity or progression, and the reason surgical intervention was selected.

Essential Modifiers for Ophthalmology Billing

Modifiers are essential in ophthalmology to indicate when services are distinct, bilateral, or occur during global periods.

Modifier 25 – Significant, separately identifiable E/M service on the same day as a minor procedure.
Used when an E/M visit is above and beyond the usual pre‑ and post‑work of a same‑day procedure (e.g., injection, laser). Modifier 25 is appended to the E/M code and must be supported by documentation.

Modifier 24 – Unrelated E/M service by the same physician during a postoperative period.
Used when an E/M visit during a surgical global period addresses a problem unrelated to the surgery (e.g., diabetic follow‑up during the global period of cataract surgery).

Modifier 57 – Decision for surgery.
Used when an E/M visit results in the decision to perform a major procedure (typically with a 90‑day global period) on the same day or the day before.

Modifier 50 – Bilateral procedure.
Used when the same procedure is performed on both eyes during the same session. Some payers prefer modifier 50; others want two line items with RT and LT.

RT/LT – Right and left eye.
Used to specify laterality for procedures and tests. Many ophthalmology codes require RT/LT to indicate which eye was treated or tested.

Modifier 59 – Distinct procedural service.
Used to indicate that a procedure or test is separate and independent from other services on the same day. Highly scrutinized; must align with NCCI edits and documentation.

X modifiers (XE, XS, XP, XU) – Alternative to 59 for distinct services.
Some payers require X modifiers instead of 59 to specify separate encounter, separate site, separate practitioner, or unusual non‑overlapping service.

Modifiers 54/55/56 – Split surgical care.
Used when one provider performs the preoperative, intraoperative, or postoperative care only. Less common in ophthalmology but relevant in shared‑care arrangements.

Global Periods and Postoperative Care in Ophthalmology

Many ophthalmology procedures carry 0‑, 10‑, or 90‑day global periods. During the global period, routine postoperative visits related to the procedure are included in the surgical payment and cannot be billed separately.

Services that may be billed separately during a global period include:

• Unrelated E/M visits (modifier 24).
• The decision for surgery for a major procedure (modifier 57).
• Distinct procedures at different sites or sessions, when allowed by NCCI and payer policy (modifier 59 or X modifiers).

Medical Necessity and Documentation Requirements

Payers require clear medical necessity for ophthalmology tests and procedures. Documentation should answer why the service was needed, what was found, and how it affected management.

For diagnostic tests (OCT, visual fields, photos, angiography):

• Document the diagnosis or symptoms prompting the test.
• Include results and a signed interpretation and report, not just images or printouts.
• Follow frequency limits in Local Coverage Determinations (LCDs) and payer policies.

For procedures (injections, lasers, surgeries):

• Document the indication, prior treatments, and clinical rationale.
• Include operative or procedure notes with technique, findings, and plan.
• For drugs, record name, dose, lot number, and laterality.

Common Ophthalmology Coding and Billing Mistakes

Certain errors repeat across ophthalmology practices and drive a significant portion of denials.

• Using 92014 for every established visit without documentation that supports a comprehensive level of service.
• Billing OCT (92133/92134) or visual fields without a documented interpretation and report.
• Overusing modifier 25 with every injection or laser visit, even when the E/M is not separately identifiable.
• Ignoring NCCI edits that bundle certain tests or procedures together (e.g., specific imaging combinations or tests with procedures).
• Failing to document laterality (right vs left) for procedures and tests, leading to incomplete claims.
• Billing routine postoperative visits during the global period as separate E/M services.
• Not checking frequency limits for tests (e.g., OCT, visual fields) before billing, resulting in automatic denials.

Simple fixes include aligning visit codes with documentation, ensuring every test has an interpretation, reserving modifier 25 for truly separate E/M services, and using claim scrubbers configured with ophthalmology‑specific NCCI rules.

Improving Ophthalmology Revenue Through Coding Reviews 

Ophthalmology practices often discover coding gaps only after patterns of denials or underpayments have persisted for months. AnnexMed’s ophthalmology-focused coding and billing reviews help identify these issues earlier and translate the findings into actionable improvements.

AnnexMed reviews high-volume ophthalmology claims, including OCT and visual field testing, injection visits, cataract procedures, and glaucoma services. Coding, modifier use, documentation, and claim submission are evaluated against current NCCI edits and payer requirements.

For ophthalmology practices seeking to improve payment consistency, reduce audit exposure, and strengthen clean claim performance, a focused coding review can provide a practical foundation for more predictable reimbursement.
