List the appropriate CPT code for the procedure and include any applicable modifiers; adhere to Medicare global surgery and CCI (correct coding initiative) rules for eyelid surgeries.
Submit physicians' services and diagnostic tests with a diagnosis code that supports medical necessity and code to the greatest level of specificity (full digit completeness).
Use the diagnosis code based on diagnostic test results as the primary diagnosis; if test results are normal or inconclusive, use the diagnosis code for the sign or symptom that prompted the test as the primary diagnosis.
When signs or symptoms are present, place the appropriate definitive diagnosis code in the first position and an available symptom diagnosis code in the second position on CMS-1500 item 21 (or electronic equivalent).

Blepharoplasty, blepharoptosis repair, or brow lift is covered when documented signs or symptoms of a functional abnormality of the upper eyelids are present as defined by the associated LCD (L34528).
Mohs micrographic surgery is covered when selected because the lesion's complexity (e.g., poorly defined borders, suspected deep invasion, recurrent lesion, prior radiation), size, or anatomic location requires maximal tissue conservation and other approaches (standard excision or destruction) are not medically reasonable or necessary.
Mohs surgery is considered covered when the surgeon performs both the surgical excision and the pathologic examination (surgeon acting in integrated surgical and pathology roles) as part of the Mohs technique.
Lab-developed tests for inherited cancer syndromes in patients with cancer as described in Local Coverage Determination (LCD) L39040 are the services addressed by this billing/coding guidance.
Blepharoplasty is covered for blepharochalasis when chronic recurrent eyelid edema has produced excess skin requiring functional repair.
Upper blepharoplasty is considered reconstructive and covered when excess upper eyelid tissue or abnormally low upper lid position produces functional visual complaints (e.g., interference with primary or downgaze reading or superior/lateral visual field loss).
