Blepharoplasty - Medical Policy Article

Abstract: Blepharoplasty may be defined as any eyelid surgery that improves abnormal function, reconstructs deformities, or enhances appearance and may be either reconstructive or cosmetic (aesthetic). Surgery of the upper eyelids is reconstructive when it provides functional vision and/or visual field benefits or improves the functioning of a malformed or degenerated body member, but cosmetic when done to enhance aesthetic appearance. Medicare does not cover cosmetic surgery or expenses incurred in connection with such surgery (CMS Publication 100-02, Medicare Benefit Policy Manual , Chapter 16, Section 20). This medical policy article specifies covered indications, limitations of coverage, and documentation requirements for non-cosmetic blepharoplasty surgery. Upper blepharoplasty and/or repair of blepharoptosis may be considered functional in nature when excess upper eyelid tissue or the upper lid position produces functional complaints. Those functional complaints are usually related to visual field impairment in primary gaze and/or down gaze (e.g., reading position). The visual impairment is commonly related to a lower than normal position of the eyelid relative to the pupil and/or to excess skin that hangs over the edge of the eyelid. Upper blepharoplasty may also be indicated for chronic dermatitis due to redundant skin and for patients with an anophthalmic socket who are experiencing prosthesis difficulties. Brow ptosis may also produce or contribute to functional visual field impairment. Either or both of these procedures may be required in some situations when a blepharoplasty would not result in a satisfactory functional repair. Similarly, surgery of the lower eyelids is reconstructive when poor eyelid tone (with or without entropion or ectropion) causes dysfunction of the “lacrimal pump,” lid retraction, and/or exposure keratoconjunctivitis that often results in epiphora (tearing). Definitions: Dermatochalasis: excess skin with loss of elasticity that is usually the result of the aging process. Blepharochalasis: excess skin associated with chronic recurrent eyelid edema that physically stretches the skin. Blepharoptosis: drooping of the upper eyelid which relates to the position of the eyelid margin with respect to the eyeball and visual axis. Pseudoptosis: “false ptosis,” for the purposes of this policy, describes the specific circumstance when the eyelid margin is usually in an appropriate anatomic position with respect to the eyeball and visual axis but the amount of excessive skin from dermatochalasis or blepharochalasis is so great as to overhang the eyelid margin and create its own ptosis. Other causes of pseudoptosis, such as hypotropia and globe malposition, are managed differently and do not apply to this policy. Pseudoptosis resulting from insufficient posterior support of the eyelid, as in phthisis bulbi, microphthalmos, congenital or acquired anophthalmos, or enophthalmos is often correctable by prosthesis modification when a prosthesis is present, although persistent ptosis may be corrected by surgical ptosis repair. Brow Ptosis: drooping of the eyebrows to such an extent that excess tissue is pushed into the upper eyelid. It is recognized that in some instances the brow ptosis may contribute to significant superior visual field loss. It may coexist with clinically significant dermatochalasis and/or lid ptosis. Horizontal Eyelid Laxity: poor eyelid tone, usually a result of the aging process, that causes (1) lid retraction without frank ectropion formation but with corneal exposure and irritation (foreign body sensation) and (2) dysfunction of the eyelid “lacrimal pump,” both of which result in symptomatic tearing (epiphora). Indications and Limitations: The conditions listed under “2” and “3” below are generally considered reconstructive and usually not subject to the medical review of conditions listed under “1” which have the potential of being considered cosmetic. Blepharoplasty may be considered reconstructive when performed for one of the following conditions that may affect both upper and lower eyelids. To correct visual impairment caused by: Dermatochalasis, including symptomatic redundant skin weighing down on the upper eyelashes (i.e., pseudoptosis) and surgically induced dermatochalasis after ptosis repair. Blepharochalasis. Blepharoptosis, including dehiscence of the aponeurosis of the levator palpebrae superioris muscle after trauma or cataract extraction, causing ptosis that may obstruct the superior visual field as well as the visual axis in downgaze (reading position). Brow ptosis. It is recognized that brow ptosis repair, in addition to blepharoplasty and/or blepharoptosis repair, may be necessary in some cases to provide an adequate functional result. Any procedure(s) involving blepharoplasty and billed to this contractor must be supported by documented patient complaints which justify functional surgery. This documentation must address the signs and symptoms commonly found in association with ptosis, pseudoptosis, blepharochalasis and/or dermatochalasis. These include (but are not limited to): Significant interference with vision or superior or lateral visual field, (e.g., difficulty seeing objects approaching from the periphery); Difficulty reading due to superior visual field loss; or, Looking through the eyelashes or seeing the upper eyelid skin. The visual fields should demonstrate a significant loss of superior visual field and potential correction of the visual field by the proposed procedures(s). A minimum 12 degree or 30 percent loss of upper field of vision with upper lid skin and/or upper lid margin in repose and elevated (by taping of the lid) to demonstrate potential correction by the proposed procedure or procedures is required. Photographs should also demonstrate the eyelid abnormality(ies) necessitating the procedures(s). (Please see “Documentation Requirements.”) Please note that in the case of prosthetic difficulties associated with an anophthalmic, microphthalmic, or enophthalmic socket, subjective complaints, examination findings (signs), and failure of prosthesis modification (when indicated) must be documented, along with photographic documentation demonstrating the contribution of one of the above mentioned orbital and/or globe abnormalities as they relate to the abnormal upper and/or lower eyelid position and intolerance of prosthesis wear. (Please see “Documentation Requirements below.”) Repair of anatomical or pathological defects, including those caused by disease (including thyroid dysfunction and cranial nerve palsies), trauma, or tumor-ablative surgery. Surgery is performed to reconstruct the normal structure of the eyelid, using local or distant tissue. Reconstruction may be necessary to protect the eye and/or improve visual function. Conditions that may require blepharoplasty, ptosis repair, ectropion repair, or entropion repair are: Ectropion and entropion Epiblepharon* Post-traumatic defects of the eyelid Post-surgical defects after excision of neoplasm(s) Lagophthalmos Congenital lagophthalmos* Congenital ectropion, entropion* Congenital ptosis* Lid retraction or lag (due to horizontal lower eyelid laxity without ectropion or entropion, causing exposure keratopathy and/or epiphora; due to horizontal upper eyelid laxity, causing floppy eyelid syndrome; or due to orbital thyroid disease). Chronic symptomatic dermatitis of pretarsal skin caused by redundant upper eyelid skin. The medical record must contain documented patient complaints and pertinent examination findings to justify the medical necessity for functional, restorative procedures(s) for the treatment of any of the above conditions. In addition, photographic documentation must demonstrate the clinical abnormality(ies) consistent with the beneficiary’s subjective complaint(s) for asterisked (*) diagnoses listed above. Relief of eye symptoms associated with blepharospasm. Primary essential (idiopathic) blepharospasm is characterized by severe squinting, secondary to uncontrollable spasms the peri-ocular facial muscles. Occasionally, it can be debilitating. If other treatments have failed or are contraindicated, a blepharoplasty combined with limited myectomy may be necessary. Patient complaints and relevant medical history (e.g., failure to respond to botulinum toxin therapy, botulinum toxin therapy is contraindicated, etc.) must be documented and available upon request. Please see “Documentation Requirements.” Documentation Requirements: The patient's medical record must contain documentation that fully supports the medical necessity for services included within this article. (Please see "Indications and Limitations of Coverage.") This documentation includes, but is not limited to, relevant medical history, physical examination, and results of pertinent diagnostic tests or procedures. This documentation must be submitted upon request. In addition, for the Group 2 CPT codes, documentation should consist of visual field results and/or photographs as specified below. Visual fields must be recorded using either a tangent screen visual field, Goldmann Perimeter (III 4-E test object), or a programmable automated perimeter, equivalent to a screening field with a single intensity strategy using a 10dB stimulus, to test a superior (vertical) extent of 50-60 degrees above fixation with targets presented at a minimum four-degree vertical separation starting at zero (0) degrees above fixation while using no wider than a 10-degree horizontal separation. Each eye should be tested with the upper eyelid at rest and repeated with the lid elevated (e.g., taped or manually retracted) to demonstrate an expected “surgical” improvement meeting or exceeding the criteria. As previously stated, visual fields must demonstrate a minimum 12 degrees or 30 percent loss of upper field of vision with upper lid skin and/or upper lid margin in repose and elevated (by taping of the lid) to demonstrate potentia
