Q  Does Medicare cover endothelial cell count (ECC) performed with a specular microscope? 

A  Yes, when medically necessary. Medicare has a longstanding national coverage determination policy (NCD 80.8) addressing reimbursement for ECC, also known as endothelial cell photography or specular microscopy. 

 

Q  What is Medicare’s coverage policy as noted in NCD 80.8? 

A  ECC is a covered procedure under Medicare when reasonable and necessary for patients who meet one or more of the following criteria:

  1. Have slit lamp evidence of an endothelial dystrophy (e.g., corneal guttata  or Fuchs endothelial dystrophy) (H18.51)* 
  2. Have slit lamp evidence of corneal edema (H18.1-, H18.2-)
  3. Are about to undergo a secondary intraocular lens implantation (aphakia: H27.0)
  4. Have had previous intraocular surgery and require cataract surgery (Z98.83-)
  5. Are about to undergo a surgical procedure associated with a higher risk to corneal endothelium, i.e., phacoemulsification or refractive surgery (subject to some limitations for excluded refractive procedures, NCD 80.7)
  6. Have evidence of posterior polymorphous dystrophy of the cornea (H18.59) or iridocorneal-endothelium syndrome (H21.26-, H18.51)
  7. Are about to be fitted with extended wear contact lenses after intraocular surgery (aphakia: H27.0, pseudophakia: Z96.1, filtering bleb: Z98.83)
     

Q  Are there any limitations on this policy?

A  Yes. When the only visual problem is cataracts, ECC is considered to be part of the presurgical eye exam provided prior to the cataract surgery, and therefore not separately billable. This test is not covered if performed in the preoperative evaluation for refractive keratoplasty to correct refractive errors.

Medical coverage policies also require that ECC, as with all diagnostic tests, must have specific relevance to the individual patient and be utilized in the management of the patient’s condition. Tests must be ordered by physicians qualified to use the results of the tests in caring for the patient. 

 

Q  Are there additional indica- tions besides those noted in Medicare’s NCD 80.8? 

A  Some Medicare Administrative Contractors (MACs) have published other covered indications that include visual disturbance (R48.3, H53.8) and congenital aphakia (Q12.3). ICD-10 rules permit coding a symptom, sign, or less- specific condition when a diagnosis is not known.1 Check your local policies; they vary. 

 

Q  Will ECC be reimbursed if performed on the same day as an eye exam or another diagnostic test?

A  Yes, subject to the limitations noted above. According to Medicare’s National Correct Coding Initiative (NCCI), separate reimbursement is allowed for ECC when performed in conjunction with exams (except technician exam, 99211) or other tests. 

 

Q  How much does Medicare allow for this test?

A  Use CPT 92286 (Anterior segment imaging with interpretation and report; with specular microscopy and endothelial cell analysis) to describe ECC. This is a bilateral service, so a single payment is made for both eyes. The 2017 national Medicare Physician Fee Schedule allowable is $39.12. Of this amount, $16.51 is assigned to the technical component and $22.61 is the value of the professional component (interpretation). These amounts are adjusted in each area by local wage indices. Other payers set their own rates, which may differ significantly.

ECC is subject to Medicare’s Multiple Procedure Payment Reduction (MPPR). This reduces the allowable for the technical component of the lesser- valued test when more than one test is performed on the same day. 

 

Q  How should ECC be documented in the medical record?

A  In addition to the photos of the endothelium, or proof that digital images exist, the chart should contain:

  • An order for the test with medical rationale
  • The date of the test
  • The reliability of the test (e.g., poor, due to corneal scarring)
  • The test findings (e.g., number of cells/mm2 morphology)
  • Comparison with prior tests (when applicable)
  • A diagnosis (if possible)
  • The impact on treatment and prognosis
  • The signature of the physician

 

Q  Is the physician’s presence required while the test is being performed?

A  Under Medicare program standards; this test needs only general supervision. General supervision means the procedure is furnished under the physician’s overall direction and control, but the physician is not required to be present during the performance of the test. 

 

Q  How often may this test be repeated on a patient?

A  There are no published limitations for repeated testing. Medicare utilization data for 2015 shows that ECC was allowed in 0.4% of all eye exams by ophthalmologists. The frequency for optometrists is similar. In general, this and all diagnostic tests are covered when medically indicated. Clear documentation of the reason for testing is always required. 

 

Q  May we ever bill the patient directly for this test?

A  Sometimes.  Explain to the patient why the test is necessary, and that Medicare or other third party payer will likely deny the claim.  Ask the patient to assume financial responsibility for the charge.  A financial waiver can take several forms.  An Advance Beneficiary Notice of Noncoverage (ABN) is required for services where Part B Medicare coverage is ambiguous or doubtful, and may be useful where a service is never covered.  For non-Medicare beneficiaries, a Notice of Exclusion from Health Plan Benefits (NEHB) is an alternative to an ABN.  

For Part C Medicare (Medicare Advantage), determination of benefits is required to identify beneficiary financial responsibility prior to performing noncovered services; MA Plans may have their own processes and waiver forms.
