Your optometry practice's financial health depends on accurate billing and coding. One small coding error can trigger a chain reaction of denied claims, delayed payments, and administrative headaches that drain both your revenue and your staff's time. Even worse, repeated mistakes can damage insurance relationships and put your practice at risk for costly audits.
In this article, we'll explore the five most common billing and coding errors that plague optometry practices and share proven strategies to prevent them, helping you maximize reimbursements and maintain a healthy revenue cycle.
The Financial Impact of Billing and Coding Errors
The numbers tell a sobering story. According to the 2024 Medicare Improper Payment Fact Sheet, healthcare providers lost $31.7 billion to improper payments, with an overall error rate of 7.66%.
For optometrists, specifically, the American Academy of Professional Coders (AAPC) reports a 6.4% error rate in Medicare Part B claims and an alarming 89.5% error rate in durable medical equipment (DME) claims—resulting in nearly $20 million in inappropriate payments.
The root causes are clear: 55.5% of errors stem from insufficient documentation, while 40.7% come from incorrect coding. These statistics represent real financial threats to practices, including audit risks, payment delays, and potential penalties reaching $50,000 for repeated violations.
Example Scenario: A practice submits 100 claims per month. With a 7.6% error rate, this means approximately 7-8 claims are initially denied. Each denied claim requires staff time for investigation, correction, and resubmission, while also delaying payment by 30-45 days on average.
5 Common Optometry Billing and Coding Mistakes
Success in optometry billing requires attention to detail and understanding of specific coding requirements. Let's examine the five most common errors that lead to claim denials and how to avoid them.
1. Medical vs. Routine Examination Confusion
Medical and routine eye examinations serve different purposes, but many optometrists struggle with the distinction. A medical exam must focus solely on tests necessary for diagnosis and treatment of a specific condition.
The key difference lies in medical necessity — an exam should be billed as medical only if the primary diagnosis is medical in nature.
Example Scenario: Patient presents with complaints of flashes and floaters. While it's tempting to perform a complete routine exam with refraction, the medical necessity only supports tests directly related to the retinal evaluation. Billing for additional routine tests could trigger a denial.
Documentation Example
Medical Exam
Chief Complaint: Sudden onset of flashes and floaters in right eye
Tests Performed: Dilated fundus examination, OCT scanning
Diagnosis: Posterior vitreous detachment
Billing: Medical insurance with relevant medical necessity documentation
2. Duplicate Claims Submission
Duplicate claims are one of the most frequent — and preventable — reasons for denial. They can happen for several reasons:
- Multiple submissions of claims with matching billed amounts
- Identical procedure codes submitted for the same date of service
- Resubmission of previously processed and paid claims
Example Scenario: A practice submits a claim for a comprehensive eye exam (CPT 92014) on March 1st. Not seeing payment by March 20th, they resubmit the claim. Meanwhile, the original claim was being processed, resulting in both claims being flagged as duplicates and denied.
Proper Tracking Example
Claim #12345
Service Date: 3/1/2025
Procedure: 92014
Initial Submission: 3/1/2025
Status Check: 3/20/2025 - In process
Follow-up: Phone verification with payer
Resolution: Payment expected by 4/1/2025
3. ICD-10 Code Specificity Issues
The Centers for Medicare and Medicaid Services (CMS) and other insurers require the highest level of specificity under the under the ICD-10 coding system for coding claims. For example, age-related nuclear cataracts require specific coding that identifies both the condition and the affected eye(s).
Example Scenario: A patient presents with an age-related cataract in the right eye. Using the unspecified code H25.9 will likely trigger a denial. Instead, the specific code H25.811 (posterior subcapsular polar age-related cataract, right eye) provides the required detail.
Coding Example
Incorrect: H25.9 (Unspecified age-related cataract)
Correct: H25.811 (Right eye specific cataract)
Supporting Documentation: Location, type, severity
Additional Findings: Visual acuity, symptoms
4. S-Codes and CPT Code Misuse
The distinction between S-codes and CPT codes creates confusion for many practices, particularly when billing different insurance types. Commercial insurers may require specific S-codes for certain services. For instance, they might only cover glasses when claims use the correct S-codes for polycarbonate and single prescription lenses.
Example Scenario: A patient needs new glasses with polycarbonate lenses. Medicare won't cover materials, but the patient's secondary commercial insurance will — if coded correctly.
Coding Example
Medicare (Won't Cover):
92015 - Refraction
92340 - Fitting of spectacles
Commercial Insurance (Will Cover):
S0580 - Polycarbonate lens
S0581 - Standard progressive lens
V2100 - Sphere, single vision
V2200 - Sphere bifocal
5. EHR System Limitations
Working with outdated Electronic Health Record systems can significantly impact coding and billing accuracy. Common issues include:
- System glitches that record incorrect examination codes
- Unalterable data fields that create documentation inconsistencies
- Inability to keep up with Medicare and Medicaid requirements
- Limited adaptation to private insurance coding changes
- Inadequate support for increasing optometric care demands
Example Scenario: A practice's outdated EHR automatically defaults to routine exam codes even for medical visits. Staff must manually override each code, increasing error risk and processing time.
System Comparison Example
Outdated EHR:
- Manual code entry required
- No real-time verification
- Limited insurance rules
- Basic error checking
Modern EHR:
- Automatic code suggestion
- Real-time claim verification
- Updated payer rules
- Advanced error prevention

Frequently Asked Questions
How do I determine if an exam should be billed as medical or routine?
Look at the primary reason for the visit. If the patient presents with medical symptoms or conditions requiring diagnosis and treatment, bill as medical. If it's for general vision assessment and updating prescriptions, bill as routine.
What's the best way to prevent duplicate claim submissions?
Implement a tracking system for all submitted claims and use automated verification tools. Wait for the standard processing time (typically 30 days) before following up on unpaid claims.
What documentation is required for medical necessity?
Include detailed symptoms, diagnosis codes, test results, and treatment plans that clearly support why each procedure was necessary for the patient's condition.
How can I improve my claim acceptance rate?
- Verify insurance coverage before appointments
- Document medical necessity thoroughly
- Use specific diagnosis codes
- Submit claims within timely filing deadlines
