Article Guidance

Article Text

This Billing and Coding Article provides billing and coding guidance for Local Coverage Determination (LCD) L35004 Blepharoplasty, Blepharoptosis Repair and Surgical Procedures of the Brow. Please refer to the LCD for reasonable and necessary requirements.

Coding Guidance

Notice: It is not appropriate to bill Medicare for services that are not covered (as described by the entire LCD) as if they are covered. When billing for non-covered services, use the appropriate modifier.

Effective October 1, 2017, The Center for Medicare & Medicaid Services (CMS) revised policy may allow payment to be made for a medically necessary upper eyelid blepharoptosis when performed with (noncovered) cosmetic blepharoplasty on the same eye during the same visit.

For correct coding guidelines and specific applicable code combinations prior to billing Medicare, please refer to the National Correct Coding Initiative (NCCI) Policy Manual for Medicare Services; Chapter 8 CPT codes 60000-69999, Section D. Ophthalmology.


Documentation Requirements

  1. All documentation must be maintained in the patient's medical record and made available to the contractor upon request.
  2. Every page of the record must be legible and include appropriate patient identification information (e.g., complete name, dates of service[s]). The documentation must include the legible signature of the physician or non-physician practitioner responsible for and providing the care to the patient.
  3. The submitted medical record must support the use of the selected ICD-10-CM code(s). The submitted CPT/HCPCS code must describe the service performed.
  4. The submitted medical record may include the following notes and operative reports as appropriate documentation to support the medical necessity of ptosis, brow and blepharoplasty procedures:
    • Clinical notes, supporting a decrease in peripheral vision and/or upper field vision.
    • Patient complaints and findings secondary to eyelid or brow malposition in example:
      • Interference with vision or visual field, related to activities such as, difficulty reading due to upper eyelid drooping, looking through the eyelashes, seeing the upper eyelid skin, or brow fatigue.
      • Chronic eyelid dermatitis due to redundant eyelid skin.
      • Difficulty wearing prosthesis.
    • Margin reflex distance (MRD1) of 2 mm or less.
    • A palpebral fissure height on down-gaze of 1mm or less, (measured with the patient fixating on an object in down–gaze with the ipsilateral brow relaxed and the contralateral lid elevated).
    • The presence of Hering’s Law meeting one of the above criteria in bullets 3 or 4. Hering’s Law of equal innervation to both upper eyelids may be considered in the documentation to perform bilateral ptosis repair in which the position of one upper eyelid has marginal criteria and the other eyelid had good supportive documentation for ptosis surgery.
  5. Preoperative photographs in the form of prints or slides are required to be submitted with the medical record to support medical necessity of ptosis, brow and blepharoplasty procedures if the record is not sufficient to determine medical necessity. If photographs are requested to support the documentation, photograph guidelines that support medical necessity include:
    • The photographs must be frontal view, canthus to canthus with the head perpendicular to the plane of the camera (not tilted) to demonstrate a skin rash or position of the true lid margin or the pseudo-lid margin.
    • For CPT codes 15820-15823 or 67901-67908: If redundant skin coexists with true lid ptosis, additional photos taken with the upper lid skin retracted to show the actual position of the true lid margin are supportive of medical necessity.
    • Oblique photos are only needed to demonstrate redundant skin on the upper eyelashes when this is the only indication for surgery.
    • Separate from the photographs, documentation in the medical record of the indicated distance thresholds (e.g., 2 mm or less from the central corneal reflex to the upper eyelid margin or skin that overhangs the eyelid margin [pseudoptosis]) is helpful to demonstrate medical necessity.

NOTE: If both a blepharoplasty and a blepharoptosis repair are planned, both must be individually documented. The medical necessity criteria for each procedure must be met and the additional required testing criteria demonstrate visual impairment that cannot be addressed by one procedure alone. This may require two sets of photographs showing the effect of drooping of redundant skin (drooping of brows and its correction by taping), and the actual presence of blepharoptosis with drooping of the upper eyelid.

10/28/2021 R3

Article revised and published on 10/28/2021 effective for dates of service on and after 03/21/2021. Current Procedural Terminology (CPT) code 67961 has been removed from the article. CPT codes 67914, 67915, 67916, 67917, 67921, 67922, 67923 and 67924 have been removed from the Group 1 CPT codes and placed in a newly created Group 2. CPT Codes 67909 and 67911 have been added to Group 2 CPT codes and to the new ICD-10-CM Group 2 Paragraph. ICD-10-CM codes H02.401, H02.402 and H02.403 were added to the Group 1 ICD-10-CM codes that support medical necessity. A new ICD-10-CM Group 2 codes that support medical necessity was created to support the new CPT Group 2 codes.

05/27/2021 R2

Article revised and published on 05/27/2021 to revise bullet point #5 in the ‘Documentation Requirements’ section for clarification purposes in response to questions from prior auth. Minor formatting changes were made in the coding section.

03/21/2021 R1

This revised Billing and Coding Article published 02/04/2021 will become effective 03/21/2021. The proposed LCD and related Billing and Coding Article will provide limited coverage for upper and lower blepharoplasty as well as repair of brow ptosis when performed for functional indications.
