The complexity of secondary and tertiary insurance claims often makes even the most seasoned medical billers pause. But understanding how to efficiently process these claims is essential for maximizing reimbursement across multiple payers. Let’s dive into the specifics.
Understanding the Sequence
Processing secondary and tertiary claims is all about knowing the right sequence. The primary insurance must always pay (or deny) its portion before the secondary can be billed. Similarly, tertiary claims can only be sent after both primary and secondary responses are received. Skipping a step in this sequence can lead to denials — and headaches.
Common sense, right? But payers have different rules, which throws a wrench in the process. Some require electronic submissions; others are stuck in the past with paper. Always check payer-specific guidelines.
Gathering Necessary Documentation
Complete documentation is your best friend. Explanation of benefits (EOBs) or electronic remittance advice (ERA) from the primary insurer is critical before moving to the next payer. Misplacing these can halt the process. If the secondary payer doesn't see a primary EOB, expect a denial — usually CO 22 (payment adjusted because this care may be covered by another payer per coordination of benefits).
Also, don't forget about coordination of benefits (COB) forms. If the secondary insurance hasn’t acknowledged the primary’s responsibility, even a perfect claim will bounce back.
Electronic vs. Paper Claims
Electronic claims submission speeds up the process — when it works. But some secondary and tertiary claims still need paper submissions. It’s frustrating. Payers like Medicare require specific forms, and other insurers might reject a claim simply because a checkbox was missed.
For electronic submissions, ensure that your EHR or practice management system supports secondary and tertiary claims. Check with your vendor if you're not sure; being stuck in queue with your software's support line is better than waiting on hold with the payer.
Timing is Everything
Timing can make or break your reimbursement. Secondary claims should be sent promptly after receiving the primary EOB. Delays can lead to timely filing denials — like CO 29 (the time limit for filing has expired). Some secondary payers only allow 30 days from the date of the primary EOB, while others give a more forgiving 90 days.
Tertiary claims have their own timelines, usually mirroring secondary deadlines. If you’re managing multiple payers, staying on schedule is non-negotiable.
Payer-Specific Guidelines
Not all payers are created equal. Each has its own quirks. For instance, UnitedHealthcare might require additional documentation for specific procedures, while Blue Cross Blue Shield could demand their own forms in addition to the standard CMS-1500. Understanding these nuances can prevent unnecessary rejections.
Always maintain an updated list of payer rules and contacts. (A spreadsheet can be a lifesaver here.) If you frequently work with the same payers, this list will become your go-to tool.
Common Denials and Solutions
Secondary claims can face several denials. A common one is CO 23 (payment adjusted due to the impact of prior payer(s) adjudication). This often happens when the secondary payer hasn’t been updated with current COB information. Ensure patient records are up-to-date and that they reflect the correct order of insurance responsibility.
Another frequent issue is mismatched information — like the patient’s name or ID number. Such simple errors can lead to denials. Double-check every detail before submission.
Tips for Efficient Processing
Prioritize Clean Claims: The cleaner the claim, the faster the payment. Double-check every field.
Track Every Submission: Use a tracking system to monitor claims through each stage. If a claim stalls, you’ll know immediately.
Use Dedicated Staff for Secondary/Tertiary Claims: Assign someone to specialize in these claims. They’ll develop the expertise needed to pre-empt problems.
Educate Patients on COB: Often, patients are unaware of what coordination of benefits entails. Educate them during visits to ensure they provide their insurance information accurately.
Follow Up Rigorously: Follow up on secondary and tertiary claims as diligently as primary ones. This isn’t just about getting paid — it’s about getting paid faster.
Wrapping It Up
Handling secondary and tertiary insurance claims isn’t just about following steps — it’s about creating a seamless workflow that minimizes errors and maximizes revenue. Understanding payer quirks, maintaining detailed records, and adhering to strict timelines will keep dollars flowing. And in a world where every reimbursement counts, mastering this process isn't just beneficial — it's essential.
