Coinsurance

What Is Coinsurance In Health Insurance And How Does It Work?

Coinsurance is the percentage of covered healthcare costs that a patient is responsible for paying after meeting their deductible. Unlike a fixed copay amount, coinsurance operates on a percentage basis, meaning the patient shares a portion of the medical expenses with their insurance provider. For example, if a plan has an 80/20 coinsurance split, the insurer pays 80% of the covered costs while the patient pays the remaining 20%.

This cost-sharing mechanism helps distribute financial responsibility between the insurer and insured, encouraging more mindful use of healthcare services. Coinsurance kicks in only after the deductible—the fixed amount the patient must pay out-of-pocket initially—is fully met.

How Does Coinsurance Differ From Copay And Deductible?

Understanding the distinctions between coinsurance, copays, and deductibles is crucial for accurate patient billing and revenue cycle management.

  • Coinsurance: A percentage of costs paid by the patient after the deductible is met.
  • Copay: A fixed dollar amount paid by the patient for specific services, regardless of deductible status.
  • Deductible: A fixed dollar amount the patient must pay out-of-pocket before insurance coverage begins.

While deductibles and copays are fixed amounts, coinsurance is variable and depends on the total cost of the covered service. This variability affects how patient financial responsibility is calculated in medical billing systems.

How Is Coinsurance Calculated In Medical Billing?

Coinsurance is calculated by applying the agreed-upon percentage to the allowed amount for a covered service after the deductible is met. The allowed amount is the negotiated price between the healthcare provider and insurer.

For example, if a patient has a 20% coinsurance and receives a service with an allowed amount of $1,000 after paying a $500 deductible, the patient’s coinsurance responsibility would be $200 (20% of $1,000). The insurer pays the remaining $800.

  • Step 1: Patient pays deductible first.
  • Step 2: Calculate coinsurance percentage on allowed amount.
  • Step 3: Patient pays coinsurance; insurer pays the rest.

This calculation impacts patient billing statements and revenue cycle workflows by determining the patient's financial responsibility after insurance adjudication.

What Are The Implications Of Coinsurance For Revenue Cycle Management?

Coinsurance directly affects patient collections and cash flow in healthcare revenue cycle management. Since coinsurance amounts are often significant and variable, effective communication and accurate billing are essential to ensure timely patient payments.

RCM professionals must:

  • Verify Insurance Benefits: Confirm coinsurance percentages and deductible status before billing.
  • Educate Patients: Provide clear explanations of coinsurance responsibilities to reduce payment delays.
  • Use Accurate Billing Systems: Ensure coinsurance is correctly calculated and reflected on patient statements.

Failure to manage coinsurance properly can lead to increased accounts receivable and patient dissatisfaction.

What Is Coinsurance In Property Insurance And How Does It Affect Claims?

In property insurance, coinsurance refers to a clause that requires property owners to insure their property to a specified percentage of its value—commonly 80%, 90%, or 100%. This level is known as the coinsurance requirement or protection level.

If the insured fails to meet this requirement, the insurer may reduce claims payments proportionally. For example, if a property is insured for less than the required percentage, the insurer applies a coinsurance penalty, reducing the claim payout.

This concept encourages adequate insurance coverage and protects insurers from underinsurance risks.
