**Abstract:**  
  
 _Fundus photography_  
Fundus photography involves the use of a retinal camera to document
abnormalities of of the retina and disease processes affecting the eye, in
order to follow the progress of such disease. The test must be used in the
medical decision making for the patient.  
  
 _Extended ophthalmoscopy_  
Extended ophthalmoscopy is the detailed examination of the retina and always
includes a true **drawing of the retina, with interpretation and report**. It
is most frequently performed utilizing an indirect lens, although it may be
performed using contact lens biomicroscopy. It may require scleral depression
and is usually performed with the pupil dilated. It is performed by the
physician when a more detailed examination (including that of the periphery)
is needed, following routine ophthalmoscopy. The examination must be used in
the medical decision making for the patient.  
  
 **Indications:**  
  
 _Fundus photography_  
Fundus photography may be indicated to document abnormalities of disease
processes affecting the eye, or to follow the progress of such disease.  
  
In order to document a disease process or follow the progress of a disease,
photographs and an interpretation and report of the test may be necessary.
Photographs and an interpretation and report of the test may also be necessary
to plan treatment for a disease process.  
  
Fundus photography may be used for the diagnosis of conditions such as macular
degeneration, retinal neoplasms, choroid disturbances and diabetic
retinopathy, glaucoma, multiple sclerosis or other central nervous system
anomalies.  
  
Fundus photography may be indicated for examination of the retina in diabetic
patients, in whom symptoms of visual disturbances may be present and in whom
retinal examination may be unremarkable or normal.  
  
 _Extended ophthalmoscopy_  
Extended ophthalmoscopy is indicated when the level of examination requires a
complete view of the posterior segment of the eye and documentation is greater
than that required for general ophthalmoscopy.  
  
An extended ophthalmoscopy may be considered medically reasonable and
necessary for the following conditions:

  * Malignant neoplasm of the retina or choroid.  
  

  * Retained (old) intraocular foreign body, either magnetic or nonmagnetic. Signs and symptoms may include a statement by the patient that something has hit his/her eye (foreign body sensation), normal or blurred vision, pain or no discomfort, and tearing.  
  

  * Retinal hemorrhage, edema, ischemia, exudates and deposits, hereditary retinal dystrophies or peripheral retinal degeneration.  
  

  * Retinal detachment with or without retinal defect. The patient may complain of light flashes, dark floating specks, and blurred vision that becomes progressively worse. This may be described by the patient as "a curtain came down over my eyes."  
  

  * Symptoms suggestive of retinal defect (ex: flashes and/or floaters).  
  

  * Retinal defects without retinal detachment.  
  

  * Diabetic retinopathy (i.e., background retinopathy or proliferative retinopathy), retinal vascular occlusion, or separation of the retinal layers. This may be evidenced by microaneurysms, cotton wool spots, exudates, hemorrhages, or fibrous proliferation.  
  

  * Experienced sudden visual loss or transient visual loss.  
  

  * Chorioretinitis, chorioretinal scars or choroidal degeneration, dystrophies, hemorrhage and rupture, or detachment.  
  

  * Sustained a penetrating wound to the orbit resulting in the retention of a foreign body in the eye.  
  

  * Sustained a blunt injury to the eye or pariorbita.  
  

  * Disorders of the vitreous body (i.e., vitreous hemorrhage or posterior vitreous detachment). Spots before the eyes (floaters) and flashing lights (photopsia) can be signs/symptoms of these disorders.  
  

  * Posterior scleritis. Signs and symptoms may include severe pain and inflammation, proptosis, limited ocular movements, and a loss of a portion of the visual field.  
  

  * Vogt-Koyanagi syndrome. A condition characterized by bilateral uveitis, dysacousia, meningeal irritation, whitening of patches of hair (poliosis), vitiligo, and retinal detachment. The disease can be initiated by a severe headache, deep orbital pain, vertigo, and nausea.  
  

  * Degenerative disorders of the globe.  
  

  * Retinoschisis and retinal cysts. Patients may complain of light flashes and floaters.  
  

  * Signs and symptoms of endophthalmitis, which may include severe pain, redness, photophobia, and profound loss of vision.   
  

  * Glaucoma or is a glaucoma suspect. This may be evidenced by increased intraocular pressure or progressive cupping of the optic nerve.  
  

  * Systemic disorders which may be associated with retinal pathology.  
  

  * High axial length myopia  
  

  * Retinal edema  
  

  * Metamorphopsia  
  

  * High-risk medication for retinopathy or optic neuropathy.  
  

  * Choroidal nevus being evaluated for malignant transformation.  
  

  * Macular degeneration.

**Limitations:**  
  
If the study is performed as a screening service, it is not covered by
Medicare.  
  
 _Fundus photography_

  * All tests must include a written interpretation. If an interpretation is not included in the same medical record with the photograph, then both the technical and professional components will be considered not medically necessary.
  * Fundus photography are bilateral services on the Medicare Physician Fee Schedule Data Base. Services performed unilaterally are subject to a reduction in fee.
  * Fundus photography is not a substitute for an annual dilated examination by a qualified professional (e.g., in diabetic patients). Fundus photographs taken by a non-eye professional and sent (transtelephonically, via internet, or by other means) to a qualified professional for interpretation are covered for the monitoring and management of active retinal disease. The interpretation of tests done with remote imaging must be performed by a physician or qualified non-physician practitioner.
  * Remote imaging for detection of retinal disease is considered screening and will be denied as non-covered.
  * Provision of fundus photography, by providers other than opthalmologists or optometrists, as a screening test to facilitate referral to a specialist is contrary to requirements for testing as codified in 42CFR 410.32, and is therefore not covered. Furthermore, the ordering/performance of fundus photography by eye specialists prior to a face-to-face encounter is similarly not covered or reimbursable.

_Extended ophthalmoscopy_

  * Extended ophthalmoscopy of a fellow eye without signs or symptoms or new abnormalities on general ophthalmoscopic exam will be denied as not medically necessary. Repeated extended ophthalmoscopy at each visit without change in signs, symptoms or condition may be denied as not medically necessary.
  * General ophthalmoscopy and biomicroscopy are part of an ophthalmologic examination and are not separately payable, but these should still be documented in the patient's medical record.
  * If indirect ophthalmoscopy is done without a drawing or does not meet the standards indicated in the attached Article (A57071), the service is not separately payable and will be considered part of a general ophthalmologic exam or E&M service.
  * Extended ophthalmoscopy performed during the global surgery period of an ophthalmologic surgery procedure, by the same provider performing the surgery, will not be separately payable unless unrelated to the condition for which the surgery was performed.
  * If the medical record does not include the interpretation and report, the extended ophthalmoscopy will be denied as not medically necessary.
  * Extended ophthalmoscopy will be denied as not medically necessary when it is done in lieu of routine ophthalmoscopy unless the indication for this more extensive examination is documented in the medical record.
  * When other ophthalmological tests (e.g., fundus photography, fluorescein angiography, ultrasound, optical coherence tomography, etc.) have been performed, extended ophthalmoscopy will be denied as not medically necessary unless there was a reasonable medical expectation that the multiple imaging services might provide additive (non-duplicative) information.
