“The examination includes a careful and thorough detection and diagnosis of
ophthalmic disorders, implementation of appropriate therapy for refractive error
and both ocular and systemic disease.”

“Based on the patient's history and findings, additional tests or
evaluations might be indicated to evaluate further a particular structure
or function. These are not routinely part of the comprehensive medical
eye clinical evaluation.”
Additional diagnostic testing may include the following: ‹
Keratometry (e.g., to assess surface quality and power) ‹
Corneal topography/tomography, including analysis ‹
Measurement of corneal thickness (pachymetry, corneal tomography) ‹
Corneal endothelial cell analysis ‹
External, slit-lamp, or fundus photography ‹
Anterior and posterior segment imaging (e.g., optical coherence tomography [OCT], anterior
segment OCT, ocular photography, high-frequency ultrasonography, or confocal microscopy) ‹
Visual fields by automated and/or manual perimetry ‹
Biometry ‹
Stereophotography or computer-based image analysis of the optic disc and retinal nerve fiber layer o macula ‹
Ophthalmic ultrasonography ‹Fluorescein or indocyanine green angiography ‹
Electrophysiological testing ‹
Microbiology and cytology of ocular or periocular specimens ‹
In-office point-of-care testing (e.g., immunochromatography) ‹
Radiologic imaging ‹
Laboratory tests for systemic disease

• Equivocal – questionable, atypical
• Location – isolate the dysfunction

WHAT IS MEDICAL NECESSITY?

OBJECTIVES
“CLINICAL OBJECTIVES :‹
• Detect and diagnose ocular abnormalities and diseases ‹
• Identify risk factors for ocular disease ‹
• Identify risk factors for systemic disease based on ocular
findings ‹
• Establish the presence or absence of ocular signs or symptoms
of systemic disease ‹
• Determine the refractive state and health status of the eye,
visual system, and related structures ‹
• Discuss the results and implications of the examination with the
patient ‹
• Initiate an appropriate management plan, including
determination of the frequency of future visits, further
diagnostic tests, referral, or treatment”
http://www.aaojournal.org/article/S0161-6420(15)01269-5/pdf
DOCUMENT NEED AND CLINICAL
OBJECTIVES ON INTERPRETATION AND
REPORT
• Interpretation and Report
• Patient Name
• Reason for Service
• Test Result
• Impression and diagnosis
• Better, worse, stable
• Impact on Care
• Signature and Date
EXAMPLE OF HOW ERG AND/OR VEP
IMPACT CARE
Results provide more specific, objective
and in-depth comparative data
More objective Impression
Consistent with Clinical Objectives
KNOW ICD CODING GUIDELINES
• Get coding order right - code the chief reason for
the test, list first the sign or symptom in absence of a
diagnosis.
“G. ICD-10-CM code for the diagnosis, condition, problem, or other reason for encounter/visit List first the ICD-10CM code for the diagnosis, condition, problem, or other reason for encounter/visit shown in the medical record to
be chiefly responsible for the services provided. List additional codes that describe any coexisting conditions. In
some cases the first-listed diagnosis may be a symptom when a diagnosis has not been established (confirmed) by
the physician.”
• “Suspected” diagnoses - coding signs, symptoms
and abnormal test results if diagnosis is uncertain.
“Uncertain diagnosis Do not code diagnoses documented as “probable”, “suspected,” “questionable,” “rule out,”
or “working diagnosis” or other similar terms indicating uncertainty. Rather, code the condition(s) to the highest
degree of certainty for that encounter/visit, such as symptoms, signs, abnormal test results, or other reason for the
visit.”

CONSIDERATIONS FOR ADDING
DIAGNOSTICS TO THE PRACTICE
 Professionally Accepted
 Clinically Useful
 Medically Necessary
 Financially Feasible
FINANCIALLY FEASIBLE
• Cost of Visual Electrophysiology Equipment:
• Varies by Manufacturer (e.g. $40-$60K)
• Meet your needs
• Less than OCT (e.g. $50-$80k)
• Supplies/Electrodes vary
• Administration – staff time
• Service and Support (training and maintenance)
• think about EMR model
NATIONALLY COVERED
Manual Section Title :
Evoked Response Tests
Benefit Category:
Diagnostic Tests (other)
Item/Service Description:
These tests measure brain responses to repetitive
visual, click or other stimuli.
Indications and Limitations
of Coverage:
Evoked response tests, including brain stem evoked
response and visual evoked response tests, are
generally accepted as safe and effective diagnostic
tools. Program payment may be made for these
procedures.

COMMON ICDS
COMMON QUESTIONS
• Frequency?
• When medically necessary
• Both tests on same day?
• No NCCIs (National Correct Coding Initiatives)
• MPPR (Multiple Procedure Payment Reduction) only applies
to ERG 92275
• Billed with office visit?
• If office visit was performed/documented
• No 99211 on ERG due to NCCI
COMMON QUESTIONS
• Documentation?
• Like any other dx test that requires and
Interpretation and Report
• Special Billing Instruction?
• HCFA 1500 box 17 requires name and NPI of
referring/ordering doctor
• ICD coding?
• List first the chief reason the service was provided
or the final diagnosis
PRACTICE VALUE
• More sensitive, specific testing to differentiate ocular from systemic
or other causes (trauma)
• Positive practice image offering more advanced diagnostics
• Build referral relationships to and from other specialists' for comanagement
