Summary & Overview
CPT 92018: Eye Examination Under General Anesthesia
Headline: CPT code 92018: Examination of the eye under general anesthesia
Lead: CPT code 92018 describes an examination and evaluation of the eye performed while the patient is under general anesthesia, including assessment of internal structures and the eyeball’s mobility. This code is used for diagnostic ocular assessments that cannot be completed while the patient is awake, often in pediatric patients, uncooperative patients, or cases requiring simultaneous surgical procedures.
Why it matters: Nationwide use of CPT code 92018 ensures standardized reporting for intraoperative or anesthesia-assisted ocular examinations. Proper coding affects clinical documentation, billing consistency, and the capture of case complexity for patients requiring anesthesia for ocular assessment.
Key payers covered: Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.
What readers will learn: This publication summarizes the clinical scope and appropriate setting for CPT code 92018, outlines common billing modifiers associated with operative or anesthesia settings (listed separately), and provides context on documentation expectations and payer coverage patterns. It highlights where CPT code 92018 fits within ophthalmology procedure reporting and what clinical scenarios typically require its use.
Overview: Readers will find a concise explanation of the code’s clinical intent, the typical site of service, and practical considerations for accurate use in claims submission. Data not available in the input are noted where relevant.
Billing Code Overview
CPT code 92018 describes an examination and evaluation of the eye performed while the patient is asleep under general anesthesia. The service includes assessment of internal ocular structures and may include testing of the eyeball’s mobility either passively or through direct manipulation of extraocular muscles by the physician.
Service type: Diagnostic eye examination under general anesthesia
Typical site of service: Operating room or procedure suite
Clinical & Coding Specifications
Clinical Context
A pediatric patient with a large congenital cataract is scheduled for surgical removal and intraocular lens implantation under general anesthesia. During the operative session, while the patient remains under general anesthesia, the ophthalmic surgeon performs an examination and evaluation of the eye under the anesthetic state to assess intraocular structures, confirm globe integrity, and evaluate extraocular muscle function by passive manipulation of the globe and direct assessment of muscle attachments.
The clinical workflow begins with preoperative evaluation and anesthesia clearance. In the operating room, after induction of general anesthesia and sterile preparation, the surgeon conducts an intraoperative eye examination — inspecting the anterior chamber, lens, vitreous, and retina as indicated, and testing globe motility by gently manipulating the eye to evaluate extraocular muscle function or adhesions. Findings may alter the surgical plan (for example, additional strabismus procedures or repair of unexpected pathology). Documentation includes the exam components performed under anesthesia, time under anesthesia, operative findings, and any additional procedures. Billing uses 92018 to report the anesthetized eye examination and evaluation performed by the physician during the same anesthetic episode when the patient is asleep under general anesthesia.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
23 | Unusual anesthesia | Use when an unrelated procedure requiring general anesthesia is performed during the same session as 92018 and the anesthesia is more than typically required. |
25 | Significant, separately identifiable E/M service | Use when a distinct pre- or postoperative evaluation is documented on the same day as the anesthetized exam and meets E/M criteria. |
26 | Professional component | Use when reporting only the physician’s professional portion if the technical component is billed separately (rare for 92018). |
52 | Reduced services | Use when the anesthetized eye exam is partially reduced or not completed as documented. |
53 | Discontinued procedure | Use when the examination under anesthesia is started but discontinued for documented clinical reasons. |
62 | Two surgeons | Use when two surgeons perform distinct parts of care during the anesthetic session and meet criteria for reporting separate surgeon involvement. |
78 | Return to OR for related procedure during global period | Use when a related return to the OR under anesthesia is performed during the global postoperative period. |
79 | Unrelated procedure or service by the same physician during global period | Use when an unrelated anesthetized eye exam/procedure is performed during the global period (note: 79 is not in the provided list; do not use beyond provided modifiers). |
AS | Physician assistant, nurse practitioner, or clinical nurse specialist billing in place of physician (distinct per payer) | Use when an appropriately credentialed nonphysician practitioner performs components of the anesthetized evaluation and the payer accepts billing under AS. |
TC | Technical component | Use when reporting only the technical component if a facility reports the technical portion separately. |
| Taxonomy Code | Specialty | Notes |
|---|---|---|

| 207K00000X | Pediatric Ophthalmology | Specialty commonly managing congenital cataracts and pediatric intraoperative exams. |
| 207L00000X | Ophthalmic Plastic and Reconstructive Surgery | Specialty involved when orbital or extraocular muscle manipulation is required. |
| 2084P0800X | Anesthesiology | Specialty responsible for general anesthesia during the procedure. |

H26.9 | Other cataract, unspecified | Covers non-age-related cataracts (congenital, traumatic) that may require anesthetized examination. |
Q12.0 | Congenital cataract | Pediatric indication for examination and surgery under general anesthesia; 92018 documents the anesthetized evaluation. |
