Official Description

Blepharoplasty, lower eyelid; with extensive herniated fat pad

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

Blepharoplasty, lower eyelid with extensive herniated fat pad, as described by CPT® Code 15821, is a surgical procedure aimed at correcting aesthetic and functional issues associated with the lower eyelids. This procedure specifically addresses the presence of herniated fat pads, which can contribute to a puffy appearance under the eyes, often leading to a tired or aged look. The surgery involves making an incision in the conjunctiva of the lower eyelid to access the underlying fat pad. The procedure may also involve severing the tendon on the lateral aspect of the eyelid to enhance visibility and access to the fat pad. The surgeon dissects the herniated fat pad from surrounding tissues, allowing for its removal or repositioning. A common technique used in this procedure is the creation of a subperiosteal tunnel, which facilitates the transposition of the fat to the tear trough area over the cheekbone, thereby improving the contour and appearance of the lower eyelid. The procedure concludes with the excision of a wedge of eyelid tissue to tighten the lower lid, followed by securing the new tendon to the periosteum of the orbital rim and closing the incision with running sutures. This comprehensive approach not only enhances the aesthetic outcome but also addresses any functional impairments related to the lower eyelid structure.

1. Indications

The procedure described by CPT® Code 15821 is indicated for patients presenting with specific conditions related to the lower eyelids. These indications include:

  • Herniated Fat Pads - The presence of extensive herniated fat pads in the lower eyelid, which can lead to a puffy appearance and contribute to an aged or fatigued look.
  • Loose or Redundant Skin - Excess skin in the lower eyelid area that may cause cosmetic concerns or functional impairments, such as obstructing vision.
  • Functional Impairment - Situations where the structural issues of the lower eyelid may affect eyelid function, leading to difficulties in closing the eyes completely or other related problems.

2. Procedure

The procedure for CPT® Code 15821 involves several detailed steps to effectively address the issues associated with the lower eyelid. These steps include:

  • Incision in the Conjunctiva - The surgeon begins by making an incision in the conjunctiva of the lower eyelid, which allows access to the underlying fat pad. This approach minimizes visible scarring and provides a direct route to the area of concern.
  • Exposure of the Fat Pad - Once the incision is made, the underlying fat pad is carefully exposed. The surgeon may need to sever the tendon on the lateral aspect of the eyelid to enhance visibility and access to the fat pad, ensuring that the procedure can be performed effectively.
  • Dissection of the Herniated Fat Pad - The herniated fat pad is then meticulously dissected free from the surrounding tissue. This step is crucial for either removing the fat or repositioning it as needed.
  • Creation of a Subperiosteal Tunnel - In many cases, a subperiosteal tunnel is created at the medial aspect of the lower lid conjunctiva. This tunnel allows for the transposition of the fat pad, which is then positioned in the tear trough area over the cheekbone to improve the contour of the lower eyelid.
  • Securing the Fat Pad - Loose sutures are placed through the skin to secure the fat pad in its new location, ensuring that it remains stable and properly positioned during the healing process.
  • Wedge Excision of Eyelid Tissue - The lateral aspect of the eyelid is incised, and a wedge of eyelid tissue is excised. This step is performed to tighten the lower lid, enhancing both the aesthetic and functional outcomes of the procedure.
  • Reconstruction of the Tendon - A new tendon is fashioned and attached to the periosteum of the orbital rim using a single suture, which helps restore the structural integrity of the eyelid.
  • Closure of the Incision - Finally, loose or redundant skin just below the lashes is grasped, pulled taut, and trimmed away. A running suture is then placed to close the skin, completing the procedure.

3. Post-Procedure

After the completion of the blepharoplasty procedure, patients can expect specific post-operative care and considerations. It is important to monitor for any signs of complications, such as excessive swelling or infection. Patients are typically advised to keep the surgical area clean and may be prescribed topical ointments to aid in healing. Cold compresses can be applied to reduce swelling and discomfort in the initial days following surgery. Follow-up appointments are essential to assess the healing process and ensure that the eyelid is recovering properly. Patients should also be informed about potential changes in sensation around the eyelid area and the importance of avoiding strenuous activities during the initial recovery phase. Overall, adherence to post-procedure instructions is crucial for achieving optimal results and minimizing risks.

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).
LT Left side (used to identify procedures performed on the left side of the body)

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).
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.)
