In Dental Billing

Coordination of Benefits (COB) is a term used by healthcare organizations which explains the determination of benefits for a patient with multiple insurance plans. There are many rules and regulations made by The American Dental Association (ADA) to accurately coordinate patient’s benefits. Following these rules will help avoid delays in payment and will ensure that insurance companies process claims correctly!

 

How does a patient end up with multiple insurance plans? Many different ways, but there are a few common examples to remember. It is common to see a child with dual coverage because both parents have their own insurance coverage. Of course, the child would have to be enrolled in both parents’ plans. Using the same scenario, can we assume that both parents also have dual coverage? If both insurance plans cover families/spouses, then it is definitely safe to assume. 

 

A few other reasons a patient might have dual insurance:

  1. Being a part of a federal insurance plan (Ex. FEHB and FEP)
  2. Being qualified for Medicaid
  3. Being an adult child (under 26) who has his or her  own coverage and also through their parents

 

Patients may be thinking, “I have two insurance plans; so that means I would get double the benefits?” That is not always the case. Having two or more insurance plans does help cover insurance expenses better through the coordination of benefits provisions. Giving your patient knowledge about their dual insurance benefits before treatment is essential. Yet again another reason insurance verification is so important. 

 

So how can we determine the order of benefits for patients with dual insurance? There are many rules to remember when setting up a patient’s account. Here are the most common rules used to determine benefits:

  1. Birthday Rule – Child has coverage from both parents’ insurance plans. The parent whose birthday falls earlier in the calendar year is primary. If the parents have the same date of birth it is determined by who has had coverage the longest with the insurance company.
  2. Subscriber Rule – When the patient is the subscriber, employee, member, policyholder of the insurance plan he or she is always primary on that plan. Any other plans where the patient is a dependent would be their secondary plan.
  3. Medicare Rule – Medicare is secondary to the plan covering the patient as a dependent.
  4. Divorce Rules – If a court decree states one of the parents is responsible for the child’s health care expenses/care, the plan of that parent is primary. 
    1. No court decree? – Order of benefits are as follows:
      1. The plan covering the custodial parent
      2. The plan covering the spouse of the custodial parent
      3. The plan covering the non-custodial parent
      4. The plan covering the spouse of the non-custodial parent

 

Dental offices need to have a basic understanding of these rules to properly handle account setups. The dental office is also responsible for making sure their patients properly understand their benefits, especially when dealing with dual insurance. This conversation should happen with the patient during treatment plan negotiations. Before all of this happens, your office must verify patients’ benefits through your insurance verification process.
