Official Description

Ophthalmological services: medical examination and evaluation with initiation of diagnostic and treatment program; comprehensive, new patient, 1 or more visits

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

A comprehensive level of general ophthalmological services is provided to a new patient within the course of one or more visits, as indicated by CPT® Code 92004. This code encompasses a thorough medical examination and evaluation of the patient's visual system, which does not need to be completed in a single session. The comprehensive evaluation includes a detailed history and general medical observations, allowing the physician to gather essential information about the patient's overall health and specific ocular concerns. The examination involves an external ocular and adnexal assessment, which covers the eyelids, eyelashes, eyebrows, eye alignment and motility, conjunctiva, cornea, and iris. Additionally, the use of a slit lamp is integral to this evaluation, enabling a magnified view of the anterior segment of the eye. The examination also assesses the gross visual field or visual acuity of each eye, ensuring that any visual impairments are identified. A sensorimotor examination is performed to evaluate eye movements, while routine ophthalmoscopy is utilized to inspect the ocular media, retina, and optic nerve for any abnormalities. Other important components of the examination include tonometry, which measures intraocular pressure, keratometry for assessing the curvature of the cornea, retinoscopy to evaluate refractive errors, and biomicroscopy for examining acute or complicated conditions. To facilitate a comprehensive examination, mydriatic agents may be employed to dilate the pupils, enhancing visualization of the ocular media and fundus. Cycloplegic agents may also be used to temporarily paralyze the ciliary muscle, aiding in the assessment of accommodation. Following the diagnostic evaluation, the physician initiates a diagnostic treatment program, which may involve prescribing necessary medications and coordinating additional special services, consultations, laboratory tests, or radiology services as required for the patient's care.

1. Indications

The procedure associated with CPT® Code 92004 is indicated for new patients requiring a comprehensive ophthalmological evaluation. This may include patients presenting with a variety of symptoms or conditions that necessitate a thorough assessment of their visual system. The following are specific indications for this procedure:

  • New Patient Evaluation Patients who have not previously received ophthalmological care and require a complete assessment of their visual health.
  • Visual Disturbances Individuals experiencing symptoms such as blurred vision, double vision, or other visual impairments that warrant a detailed examination.
  • Ocular Health Monitoring Patients with a history of ocular diseases or conditions that require regular monitoring and evaluation.
  • Preoperative Assessment Individuals who may need surgical intervention for ocular conditions and require a comprehensive evaluation prior to surgery.

2. Procedure

The procedure for CPT® Code 92004 involves several detailed steps to ensure a comprehensive evaluation of the patient's visual system. Each step is crucial for gathering the necessary information to diagnose and initiate a treatment plan.

  • Step 1: Patient History and General Medical Observations The physician begins by taking a thorough history of the patient's ocular and medical background. This includes understanding any previous eye conditions, surgeries, or treatments, as well as any systemic health issues that may impact ocular health.
  • Step 2: External Ocular and Adnexal Examination A detailed examination of the external structures of the eye is performed, including the eyelids, eyelashes, eyebrows, and surrounding tissues. The physician assesses eye alignment and motility, as well as the conjunctiva, cornea, and iris for any abnormalities.
  • Step 3: Slit Lamp Examination The slit lamp is utilized to provide a magnified view of the anterior segment of the eye, allowing for a detailed assessment of the cornea, lens, and anterior chamber. This examination is critical for identifying conditions such as cataracts or corneal abnormalities.
  • Step 4: Visual Acuity and Gross Visual Field Testing The physician evaluates the visual acuity of each eye using standardized charts and assesses the gross visual field to identify any peripheral vision loss.
  • Step 5: Sensorimotor Examination This step involves assessing the eye movements and coordination between the eyes to ensure proper function and alignment.
  • Step 6: Routine Ophthalmoscopy The physician performs a routine ophthalmoscopy to examine the ocular media, retina, and optic nerve for any signs of disease or abnormalities.
  • Step 7: Tonometry Intraocular pressure is measured using tonometry to screen for glaucoma and other conditions that may affect eye health.
  • Step 8: Keratometry and Retinoscopy Keratometry is performed to measure the curvature of the cornea, while retinoscopy is used to evaluate refractive errors and determine the need for corrective lenses.
  • Step 9: Biomicroscopy For patients with acute or complicated conditions, biomicroscopy is utilized to provide a detailed examination of the anterior segment and assess any urgent issues.
  • Step 10: Mydriasis and Cycloplegia Mydriatic agents may be administered to dilate the pupils, enhancing the examination of the ocular media and fundus. Cycloplegic agents may also be used to temporarily paralyze the ciliary muscle, facilitating a more thorough assessment of accommodation.
  • Step 11: Initiation of Diagnostic Treatment Program Following the comprehensive evaluation, the physician initiates a diagnostic treatment program, which may include prescribing medications, arranging for additional special services, consultations, laboratory tests, or radiology services as necessary for the patient's care.

3. Post-Procedure

After the completion of the comprehensive ophthalmological evaluation associated with CPT® Code 92004, the patient may be provided with specific post-procedure care instructions. This may include guidance on any prescribed medications, follow-up appointments, and recommendations for monitoring visual changes. Patients may also be advised on potential side effects of any mydriatic or cycloplegic agents used during the examination, such as temporary blurred vision or light sensitivity. It is essential for the physician to communicate the importance of adhering to follow-up care and any additional evaluations that may be necessary based on the findings of the examination.

22 Increased procedural services: when the work required to provide a service is substantially greater than typically required, it may be identified by adding modifier 22 to the usual procedure code. documentation must support the substantial additional work and the reason for the additional work (ie, increased intensity, time, technical difficulty of procedure, severity of patient's condition, physical and mental effort required). note: this modifier should not be appended to an e/m service.
27 Multiple outpatient hospital e/m encounters on the same date: for hospital outpatient reporting purposes, utilization of hospital resources related to separate and distinct e/m encounters performed in multiple outpatient hospital settings on the same date may be reported by adding modifier 27 to each appropriate level outpatient and/or emergency department e/m code(s). this modifier provides a means of reporting circumstances involving evaluation and management services provided by physician(s) in more than one (multiple) outpatient hospital setting(s) (eg, hospital emergency department, clinic). note: this modifier is not to be used for physician reporting of multiple e/m services performed by the same physician on the same date. for physician reporting of all outpatient evaluation and management services provided by the same physician on the same date and performed in multiple outpatient setting(s) (eg, hospital emergency department, clinic), see evaluation and management, emergency department, or preventive medicine services codes.
51 Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d).
52 Reduced services: under certain circumstances a service or procedure is partially reduced or eliminated at the discretion of the physician or other qualified health care professional. under these circumstances the service provided can be identified by its usual procedure number and the addition of modifier 52, signifying that the service is reduced. this provides a means of reporting reduced services without disturbing the identification of the basic service. note: for hospital outpatient reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well-being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for asc hospital outpatient use).
58 Staged or related procedure or service by the same physician or other qualified health care professional during the postoperative period: it may be necessary to indicate that the performance of a procedure or service during the postoperative period was: (a) planned or anticipated (staged); (b) more extensive than the original procedure; or (c) for therapy following a surgical procedure. this circumstance may be reported by adding modifier 58 to the staged or related procedure. note: for treatment of a problem that requires a return to the operating/procedure room (eg, unanticipated clinical condition), see modifier 78.
59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.
76 Repeat procedure or service by same physician or other qualified health care professional: it may be necessary to indicate that a procedure or service was repeated by the same physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 76 to the repeated procedure or service. note: this modifier should not be appended to an e/m service.
79 Unrelated procedure or service by the same physician or other qualified health care professional during the postoperative period: the individual may need to indicate that the performance of a procedure or service during the postoperative period was unrelated to the original procedure. this circumstance may be reported by using modifier 79. (for repeat procedures on the same day, see modifier 76.)
93 Synchronous telemedicine service rendered via telephone or other real-time interactive audio-only telecommunications system : synchronous telemedicine service is defined as a real-time interaction between a physician or other qualified health care professional and a patient who is located away at a distant site from the physician or other qualified health care professional. the totality of the communication of information exchanged between the physician or other qualified health care professional and the patient during the course of the synchronous telemedicine service must be of an amount and nature that is sufficient to meet the key components and/or requirements of the same service when rendered via a face-to-face interaction.
99 Multiple modifiers: under certain circumstances 2 or more modifiers may be necessary to completely delineate a service. in such situations modifier 99 should be added to the basic procedure, and other applicable modifiers may be listed as part of the description of the service.
