Ophthalmic biometry by ultrasound echography, specifically the A-scan method, is a diagnostic procedure that utilizes a single dimension, amplitude-modulated sound beam emitted from the tip of an ultrasound probe. This technique is primarily employed to measure the length of the eye, which is a critical factor in determining the refractive power necessary for vision correction. The procedure is particularly significant in the context of cataract surgery, where the natural crystalline lens of the eye is removed and replaced with an intraocular lens (IOL). The refractive power of the eye is influenced by both the cornea and the crystalline lens, and accurate measurements obtained through A-scan biometry are essential for calculating the appropriate power of the IOL to be implanted. This ensures that patients achieve optimal visual outcomes post-surgery. It is important to note that while code 76516 is designated for ophthalmic biometry using the A-scan method alone, code 76519 is specifically used when the procedure includes the calculation of IOL power, highlighting the distinction between the two coding scenarios.

Ophthalmic biometry by ultrasound echography (A-scan) is indicated for the following conditions:
The procedure for ophthalmic biometry using ultrasound echography (A-scan) involves several key steps:
After the A-scan biometry procedure, patients may experience minimal discomfort, which typically resolves quickly. There are no specific post-procedure restrictions, and patients can usually resume normal activities immediately. However, it is essential for the healthcare provider to review the obtained measurements with the patient and discuss the next steps, particularly if the biometry is part of a preoperative assessment for cataract surgery. Follow-up appointments may be scheduled to ensure that the calculated IOL power aligns with the patient's visual needs and surgical plans.

| 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) | 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. | 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). | 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. | 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). | 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). | CC | Procedure code change (use 'cc' when the procedure code submitted was changed either for administrative reasons or because an incorrect code was filed) | 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 | GW | Service not related to the hospice patient's terminal condition | 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 | X5 | Diagnostic services requested by another clinician: for reporting services by a clinician who furnishes care to the patient only as requested by another clinician or subsequent and related services requested by another clinician; this modifier is reported for patient relationships that may not be adequately captured by the above alternative categories; reporting clinician service examples include but are not limited to, the radiologist's interpretation of an imaging study requested by another clinician | XU | Unusual non-overlapping service, the use of a service that is distinct because it does not overlap usual components of the main service |
