Computerized ophthalmic diagnostic imaging, specifically optical coherence tomography (OCT), is a sophisticated, noninvasive imaging technique utilized to visualize the structures of the posterior segment of the eye. This procedure employs the principle of backscattering of light to create detailed images, allowing for the assessment of various diseases that may affect the optic nerve or retina. The imaging can be performed on one eye (unilateral) or both eyes (bilateral), providing flexibility based on clinical needs. There are two primary types of laser scanning devices used in this imaging process: confocal laser scanning ophthalmoscopy and scanning laser polarimetry. Confocal laser scanning topography generates stereoscopic videographic digitized images, which are essential for calculating precise measurements of both anterior and posterior eye structures. On the other hand, scanning laser polarimetry focuses on measuring changes in the linear polarization of light, utilizing a polarimeter and a scanning laser ophthalmoscope to achieve its results. During the procedure, the patient is positioned in front of the scanning device and is instructed to maintain focus on an internal target displayed by the computer. This setup allows for the acquisition of multiple radial scans of the posterior segment of the eye, including the optic nerve head and retina. The resulting digitized images are presented on a monitor, where the computer processes and calculates critical measurements such as optic nerve head dimensions and retinal thickness. These images and measurements are subsequently reviewed and interpreted by a physician, culminating in a comprehensive written report that details the findings of the examination.

The procedure of computerized ophthalmic diagnostic imaging using optical coherence tomography (OCT) is indicated for the evaluation of various conditions affecting the optic nerve and retina. The following are the specific indications for performing this imaging technique:
The procedure for computerized ophthalmic diagnostic imaging using optical coherence tomography (OCT) involves several key steps that ensure accurate imaging and assessment of the posterior segment of the eye. The following outlines the procedural steps:
After the completion of the computerized ophthalmic diagnostic imaging procedure, there are several considerations for post-procedure care. Patients may resume their normal activities immediately, as the procedure is noninvasive and does not require any recovery time. The physician will provide the patient with the written report detailing the findings, which may include recommendations for further evaluation or treatment based on the results. Follow-up appointments may be scheduled to discuss the findings in detail and to determine any necessary next steps in the management of the patient's ocular health.

| 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). | 26 | Professional component: certain procedures are a combination of a physician or other qualified health care professional component and a technical component. when the physician or other qualified health care professional component is reported separately, the service may be identified by adding modifier 26 to the usual procedure number. | TC | Technical component; under certain circumstances, a charge may be made for the technical component alone; under those circumstances the technical component charge is identified by adding modifier 'tc' to the usual procedure number; technical component charges are institutional charges and not billed separately by physicians; however, portable x-ray suppliers only bill for technical component and should utilize modifier tc; the charge data from portable x-ray suppliers will then be used to build customary and prevailing profiles | 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. | GA | Waiver of liability statement issued as required by payer policy, individual case | GC | This service has been performed in part by a resident under the direction of a teaching physician | AQ | Physician providing a service in an unlisted health professional shortage area (hpsa) | GZ | Item or service expected to be denied as not reasonable and necessary | GW | Service not related to the hospice patient's terminal condition | RT | Right side (used to identify procedures performed on the right side of the body) | LT | Left side (used to identify procedures performed on the left side of the body) | XS | Separate structure, a service that is distinct because it was performed on a separate organ/structure | Q6 | Service furnished under a fee-for-time compensation arrangement by a substitute physician or by a substitute physical therapist furnishing outpatient physical therapy services in a health professional shortage area, a medically underserved area, or a rural area | XU | Unusual non-overlapping service, the use of a service that is distinct because it does not overlap usual components of the main service | XE | Separate encounter, a service that is distinct because it occurred during a separate encounter | SC | Medically necessary service or supply | CR | Catastrophe/disaster related | 24 | Unrelated evaluation and management service by the same physician or other qualified health care professional during a postoperative period: the physician or other qualified health care professional may need to indicate that an evaluation and management service was performed during a postoperative period for a reason(s) unrelated to the original procedure. this circumstance may be reported by adding modifier 24 to the appropriate level of e/m service. | 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). | GY | Item or service statutorily excluded, does not meet the definition of any medicare benefit or, for non-medicare insurers, is not a contract benefit | 25 | Significant, separately identifiable evaluation and management service by the same physician or other qualified health care professional on the same day of the procedure or other service: it may be necessary to indicate that on the day a procedure or service identified by a cpt code was performed, the patient's condition required a significant, separately identifiable e/m service above and beyond the other service provided or beyond the usual preoperative and postoperative care associated with the procedure that was performed. a significant, separately identifiable e/m service is defined or substantiated by documentation that satisfies the relevant criteria for the respective e/m service to be reported (see evaluation and management services guidelines for instructions on determining level of e/m service). the e/m service may be prompted by the symptom or condition for which the procedure and/or service was provided. as such, different diagnoses are not required for reporting of the e/m services on the same date. this circumstance may be reported by adding modifier 25 to the appropriate level of e/m service. note: this modifier is not used to report an e/m service that resulted in a decision to perform surgery. see modifier 57 for significant, separately identifiable non-e/m services, see modifier 59. | 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.) | CG | Policy criteria applied | X2 | Continuous/focused services: for reporting services by clinicians whose expertise is needed for the ongoing management of a chronic disease or a condition that needs to be managed and followed with no planned endpoint to the relationship; reporting clinician service examples include but are not limited to: a rheumatologist taking care of the patient's rheumatoid arthritis longitudinally but not providing general primary care services | 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. | 32 | Mandated services: services related to mandated consultation and/or related services (eg, third party payer, governmental, legislative or regulatory requirement) may be identified by adding modifier 32 to the basic procedure. | 50 | Bilateral procedure: unless otherwise identified in the listings, bilateral procedures that are performed at the same session, should be identified by adding modifier 50 to the appropriate 5 digit code. note: this modifier should not be appended to designated "add-on" codes (see appendix d). | 57 | Decision for surgery: an evaluation and management service that resulted in the initial decision to perform the surgery may be identified by adding modifier 57 to the appropriate level of e/m service. | 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. | 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. | 77 | Repeat procedure by another physician or other qualified health care professional: it may be necessary to indicate that a basic procedure or service was repeated by another physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 77 to the repeated procedure or service. note: this modifier should not be appended to an e/m service. | 95 | Synchronous telemedicine service rendered via a real-time interactive audio and video 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 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 would be sufficient to meet the key components and/or requirements of the same service when rendered via a face-to-face interaction. modifier 95 may only be appended to the services listed in appendix p. appendix p is the list of cpt codes for services that are typically performed face-to-face, but may be rendered via a real-time (synchronous) interactive audio and video telecommunications system. | AG | Primary physician | AM | Physician, team member service | AP | Determination of refractive state was not performed in the course of diagnostic ophthalmological examination | CC | Procedure code change (use 'cc' when the procedure code submitted was changed either for administrative reasons or because an incorrect code was filed) | E1 | Upper left, eyelid | FR | The supervising practitioner was present through two-way, audio/video communication technology | GK | Reasonable and necessary item/service associated with a ga or gz modifier | GV | Attending physician not employed or paid under arrangement by the patient's hospice provider | GX | Notice of liability issued, voluntary under payer policy | JZ | Zero drug amount discarded/not administered to any patient | KX | Requirements specified in the medical policy have been met | P2 | A patient with mild systemic disease | PC | Wrong surgery or other invasive procedure on patient | PD | Diagnostic or related non diagnostic item or service provided in a wholly owned or operated entity to a patient who is admitted as an inpatient within 3 days | PN | Non-excepted service provided at an off-campus, outpatient, provider-based department of a hospital | PO | Excepted service provided at an off-campus, outpatient, provider-based department of a hospital | Q0 | Investigational clinical service provided in a clinical research study that is in an approved clinical research study | Q1 | Routine clinical service provided in a clinical research study that is in an approved clinical research study | Q5 | Service furnished under a reciprocal billing arrangement by a substitute physician or by a substitute physical therapist furnishing outpatient physical therapy services in a health professional shortage area, a medically underserved area, or a rural area | QJ | Services/items provided to a prisoner or patient in state or local custody, however the state or local government, as applicable, meets the requirements in 42 cfr 411.4 (b) | T5 | Right foot, great toe | VP | Aphakic patient | XP | Separate practitioner, a service that is distinct because it was performed by a different practitioner |
