Indications and Limitations of Coverage and/or Medical Necessity

The visual field is the area within which objects may be seen when the eye is fixed. To standardize testing, several automated and computerized perimeters are available. However, manual perimeters are also utilized.

Medicare will consider visual field examinations to be medically reasonable and necessary under any of the following conditions:

• The patient has inflammation or disorders of the eyelids potentially affecting the visual field.

• The patient has a documented diagnosis of glaucoma.

Please note: stabilization or progression of glaucoma can be monitored only by a visual field examination, and the frequency of such examinations is dependent on the variability of intraocular pressure measurements (e.g., progressive increases despite treatment indicate a worsening condition), the appearance of new hemorrhages, and progressive cupping of the optic nerve.

• The patient is a glaucoma suspect as evidenced by an increase in intraocular pressure, asymmetric intraocular measurements of greater than 2-3 mm Hg between the two eyes, or has optic nerves suspicious for glaucoma which may be manifested as asymmetrical cupping, disc hemorrhage, or an absent or thinned temporal rim.

• The patient has a documented disorder of the optic nerve, the neurologic visual pathway, or retina.

Please note: patients with a previously diagnosed retinal detachment do not need a pretreatment visual field examination. Additionally, patients with an established diagnosed cataract do not need a follow-up visual field unless other presenting symptomatology is documented. In patients about to undergo cataract extraction, who do not have glaucoma and are not glaucoma suspects, a visual field is not indicated.

• The patient has had a recent intracranial hemorrhage, an intracranial mass or a recent measurement of increased intracranial pressure with or without visual symptomatology.

• The patient has a recently documented occlusion and/or stenosis of cerebral and precerebral arteries, a recently diagnosed transient cerebral ischemia, or giant cell arteritis.

• The patient is having an initial workup for buphthalmos, congenital anomalies of the posterior segment, or congenital ptosis.

• The patient has inflammation or disorders of the orbit, potentially affecting the visual field.

• The patient has sustained a significant eye injury.

• The patient has an unexplained visual loss which may be described as “trouble seeing” or “vision going in and out”.

• The patient has a pale or swollen optic nerve documented by a visual exam of recent origin.

• The patient is having some new functional limitations which may be due to visual field loss (e.g., reports by family that patient is running into things).

• The patient is being evaluated initially for macular degeneration or has experienced central vision loss resulting in vision measured at or below 20/70.

Please note: repeated examinations for a diagnosis of macular degeneration or an experienced central vision loss are not necessary unless changes in vision are documented or to evaluate the results of a surgical intervention.

• Repeat visual field examinations for patients undergoing surgery of the upper eyelid(s) and brow (see LCD L29002 FL part A; L29034 PR/VI part A) are considered reasonable and medically necessary. The initial (taped) and repeat (untaped) visual field examination should be performed on the same date of service.

• The patient is receiving or has completed treatment of a high-risk medication that may cause visual side effects (e.g., a patient on plaquenil may develop retinopathy).

Coding Information

Bill Type Codes:

Contractors may specify Bill Types to help providers identify those Bill Types typically used to report this service. Absence of a Bill Type does not guarantee that the policy does not apply to that Bill Type. Complete absence of all Bill Types indicates that coverage is not influenced by Bill Type and the policy should be assumed to apply equally to all claims.

Revenue Codes:

Contractors may specify Revenue Codes to help providers identify those Revenue Codes typically used to report this service. In most instances Revenue Codes are purely advisory; unless specified in the policy services reported under other Revenue Codes are equally subject to this coverage determination. Complete absence of all Revenue Codes indicates that coverage is not influenced by Revenue Code and the policy should be assumed to apply equally to all Revenue Codes.

General Information

Documentations Requirements

Medical record documentation maintained by the performing physician must clearly indicate the medical necessity of the service being billed. In addition, documentation that the service was performed must be included in the patient’s medical record. This information is normally found in the office/progress notes, hospital notes, and/or procedure report.

Documentation should support the criteria for coverage as set forth in the “Indications and Limitations of Coverage and/or Medical Necessity” section of this policy.

Appendices

Utilization Guidelines It is expected that these services would be performed as indicated by current medical literature and/or standards of practice. When services are performed in excess of established parameters, they

may be subject to review for medical necessity.
