Official Description

Paracentesis of anterior chamber of eye (separate procedure); with removal of blood, with or without irrigation and/or air injection

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 65815 refers to a paracentesis of the anterior chamber of the eye, which is a specialized surgical intervention aimed at addressing hyphema. Hyphema is characterized by the accumulation of blood in the anterior chamber, the fluid-filled space between the cornea and the iris, often resulting from ocular trauma. This procedure is classified as a separate procedure, indicating that it is performed independently and is not part of a more extensive surgical operation. During the paracentesis, the eye is first anesthetized using topical eye drops to ensure patient comfort. The surgeon then creates two small incisions, or paracentesis sites, in the eye using a precise knife blade. A needle or cannula is subsequently inserted into one of these sites to facilitate the removal of the pooled blood. The surgeon irrigates the anterior chamber with a balanced saline solution to wash out the loose blood while carefully monitoring the intraocular pressure throughout the process. If the presence of a blood clot is detected and the irrigation does not sufficiently lower the intraocular pressure, the surgeon may slightly enlarge the paracentesis site to allow for the removal of the clot through irrigation and aspiration techniques. In some cases, air may be injected into the eye after the procedure to help stabilize the intraocular pressure, ensuring optimal recovery and function of the eye.

1. Indications

The paracentesis of the anterior chamber of the eye, as described by CPT® Code 65815, is indicated for the treatment of hyphema. This condition is characterized by the presence of blood in the anterior chamber of the eye, which can occur due to various factors, primarily trauma. The procedure is performed to alleviate the symptoms associated with hyphema and to prevent potential complications such as increased intraocular pressure, which can lead to further ocular damage.

  • Hyphema A collection of blood in the anterior chamber of the eye, often resulting from trauma.

2. Procedure

The procedure begins with the administration of topical anesthetic eye drops to numb the eye, ensuring that the patient experiences minimal discomfort during the intervention. Following anesthesia, the surgeon creates two paracentesis sites using a precise knife blade. These small incisions are strategically placed to facilitate access to the anterior chamber. Once the sites are established, a needle or cannula is inserted into one of the paracentesis sites. The surgeon then irrigates the anterior chamber with a balanced saline solution, which helps to wash out the loose blood that has accumulated. Throughout this process, the intraocular pressure is closely monitored to assess the effectiveness of the irrigation. If the irrigation does not sufficiently reduce the intraocular pressure and a blood clot is identified, the surgeon may enlarge the paracentesis site slightly to allow for the removal of the clot. This is achieved through additional irrigation and aspiration techniques. After the successful removal of blood and any clots, air may be injected into the eye to help stabilize the intraocular pressure, promoting optimal recovery.

  • Step 1: Administer topical anesthetic eye drops to numb the eye.
  • Step 2: Create two paracentesis sites using a knife blade for access to the anterior chamber.
  • Step 3: Insert a needle or cannula into one of the paracentesis sites.
  • Step 4: Irrigate the anterior chamber with balanced saline solution to remove loose blood.
  • Step 5: Monitor intraocular pressure during the irrigation process.
  • Step 6: If necessary, enlarge the paracentesis site to remove a blood clot using irrigation and aspiration.
  • Step 7: Inject air into the eye to stabilize intraocular pressure after the procedure.

3. Post-Procedure

After the paracentesis procedure, patients are typically monitored for any immediate complications, including changes in intraocular pressure or signs of infection. It is essential to follow up with the healthcare provider to assess the success of the procedure and to ensure that the intraocular pressure remains stable. Patients may be advised to avoid strenuous activities and to adhere to any prescribed post-operative care instructions, which may include the use of additional eye drops or medications to promote healing and prevent infection. Regular follow-up appointments are crucial to monitor the recovery process and to address any concerns that may arise.

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.
RT Right side (used to identify procedures performed on the right side of the body)
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).
54 Surgical care only: when 1 physician or other qualified health care professional performs a surgical procedure and another provides preoperative and/or postoperative management, surgical services may be identified by adding modifier 54 to the usual procedure number.
55 Postoperative management only: when 1 physician or other qualified health care professional performed the postoperative management and another performed the surgical procedure, the postoperative component may be identified by adding modifier 55 to the usual procedure number.
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.
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.)
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.
