Blepharoplasty, blepharoptosis repair, and brow lift are surgeries that may be
performed to improve function or provided strictly for cosmetic reasons.
Medicare considers surgeries performed to improve function as reasonable and
necessary. Surgeries performed solely for cosmetic reasons are not considered
reasonable and necessary and therefore, not covered by Medicare.  
  
When eyelid surgery is done to repair defects caused by trauma or tumor-
ablative surgery (ectropion/entropion/corneal exposure), treat periorbital
sequelae of thyroid disease and nerve palsy, or relieve refractory symptoms of
blepharospasm, the procedure should be considered "reconstructive". This may
involve rearrangement or excision of the structures with the eyelids and/or
tissues of the cheek, forehead, and nasal areas. Occasionally, a graft of skin
or other tissues is transplanted to replace deficient eyelid components.  
  
 **Blepharoptosis Repair, Blepharoplasty, and Browplasty**  
  
Upper blepharoplasty (removal of upper eyelid skin) and/or repair of
blepharoptosis (drooping of the upper eyelid, which relates to the position of
the eyelid margin with respect to the eyeball and visual axis) is considered
functional in nature when the upper lid position or overhanging skin (see
"pseudoptosis" below) is sufficiently low to produce a functional deficit
related to visual field impairment or brow fatigue.  
  
Other functional indications for upper blepharoplasty include:

  * Dermatochalasis: excess skin with loss of elasticity that is usually the result of the aging process
  * Chronic dermatitis due to blepharochalasis (excess skin associated with chronic recurrent eyelid edema that physically stretches the skin) due to severe allergy or thyroid eye disease
  * Significant/extreme difficulty fitting spectacles due to excessive eyelid tissue
  * Primary essential idiopathic blepharospasm (uncontrollable spasms of the periorbital muscles) that is debilitating for which all other treatments have failed or are contraindicated
  * Anophthalmic socket with ptosis contributing to difficulty fitting a prosthesis

Pseudoptosis, "false ptosis", for the purposes of this policy, describes the
specific circumstance where 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. 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. Persistent ptosis may require surgical ptosis
repair.  
  
Brow ptosis (drooping of the eyebrows to such an extent that excess tissue is
pushed into the upper eyelid) may also produce or contribute to functional
visual field impairment. Brow ptosis repair may be required in some situations
in place of, or in addition to, upper lid blepharoplasty to achieve a
satisfactory functional repair.  
  
 **Other Eyelid Surgeries**  
  
Other eyelid surgeries may be considered reconstructive in nature for the
following indications where there is functional impairment as documented by
preoperative frontal and lateral photographs:

  * Ectropion, entropion, or epiblepharon repair for corneal and/or conjunctival injury
  * Disease due to ectropion, entropion, trichiasis, or epiblepharon
  * Poor eyelid tone (with or without entropion) that causes lid retraction and exposure keratoconjunctivitis and often, epiphora
  * Lower eyelid edema due to a metabolic or inflammatory disorder when the edema is causing a persistent visual impairment (e.g., secondary to systemic corticosteroid therapy, myxedema, Grave's disease, nephrotic syndrome) and is unresponsive to documented conservative medical management.

**When a noncovered cosmetic procedure is performed in the same operative
session** as a covered surgical procedure, benefits will be provided for the
covered procedure only. For example, if blepharochalasis could be resolved
sufficiently by brow ptosis repair alone, an upper blepharoplasty in addition
would be considered cosmetic. Similarly, if a visual field deficit could be
resolved sufficiently by upper blepharoplasty alone (for tissue hanging over
the lid margin), a blepharoptosis repair in addition would be considered
cosmetic.
