Official Description

Paracentesis of anterior chamber of eye (separate procedure); with removal of aqueous

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

Paracentesis of the anterior chamber of the eye, as described by CPT® Code 65800, is a specialized procedure aimed at the removal of aqueous humor from the eye's anterior chamber. This procedure can serve both diagnostic and therapeutic purposes. In a diagnostic context, paracentesis is often utilized to investigate conditions such as uveitis, where the removal of aqueous humor allows for the identification of infectious organisms or other pathological entities present in the fluid. On the therapeutic side, this procedure is performed to alleviate elevated intraocular pressure, which can be critical in managing conditions like glaucoma. The process involves the careful insertion of a needle or an aqueous pipette into the eye, typically at the paralimbal area of the cornea, ensuring that the procedure is conducted with precision to minimize discomfort and risk to the patient. Prior to the procedure, anesthetic eye drops are administered to numb the eye, enhancing patient comfort during the intervention. The positioning of the patient at the slit lamp is crucial for optimal access and visualization during the procedure, allowing for accurate and effective removal of the aqueous humor.

1. Indications

Paracentesis of the anterior chamber of the eye is indicated for specific conditions that necessitate the removal of aqueous humor. The following are the primary indications for this procedure:

  • Uveitis - This condition may require diagnostic removal of aqueous to identify infectious organisms or other underlying causes.
  • Elevated Intraocular Pressure - Therapeutic removal of aqueous is performed to lower intraocular pressure, which is essential in managing conditions such as glaucoma.

2. Procedure

The procedure for paracentesis of the anterior chamber of the eye involves several critical steps to ensure safety and effectiveness. Each step is outlined as follows:

  • Preparation - The patient is first positioned comfortably at the slit lamp, which provides the necessary illumination and magnification for the procedure. Anesthetic eye drops are instilled to numb the eye, minimizing discomfort during the intervention.
  • Insertion of the Needle or Aqueous Pipette - A needle attached to a syringe or an aqueous pipette is carefully inserted at the paralimbal aspect of the cornea. This insertion is done above and parallel to the iris to access the anterior chamber effectively.
  • Aspirating Aqueous Humor - If a needle and syringe are used, the plunger is gently pulled back to aspirate the aqueous humor into the syringe. Alternatively, if an aqueous pipette is employed, the suction-infusion bulb, which was compressed prior to insertion to create a vacuum, is released to allow the aqueous to be aspirated into the pipette.

3. Post-Procedure

After the paracentesis procedure, patients may be monitored for any immediate complications or adverse reactions. It is essential to observe for signs of infection or bleeding at the site of needle insertion. Patients are typically advised to avoid rubbing or touching the eye and may be prescribed topical antibiotics to prevent infection. Follow-up appointments may be scheduled to assess intraocular pressure and overall eye health, ensuring that the therapeutic goals of the procedure are met and that any underlying conditions are managed appropriately.

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.
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.)
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).
78 Unplanned return to the operating/procedure room by the same physician or other qualified health care professional following initial procedure for a related procedure during the postoperative period: it may be necessary to indicate that another procedure was performed during the postoperative period of the initial procedure (unplanned procedure following initial procedure). when this procedure is related to the first, and requires the use of an operating/procedure room, it may be reported by adding modifier 78 to the related procedure. (for repeat procedures, see modifier 76.)
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).
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.
SG Ambulatory surgical center (asc) facility service
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.
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.
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
