Who is defined as the "guarantor" in medical billing?

In medical billing, the "guarantor" is defined as the individual who is ultimately responsible for the payment of the bill, particularly in situations involving self-pay balances. This person may not necessarily be the one receiving the services but is responsible for ensuring that the payment is made, regardless of insurance involvement or other factors.

In many cases, the guarantor might be a family member or guardian, especially in situations involving minors or dependents. Understanding the role of the guarantor is crucial for billing practices, as it affects how bills are generated, sent, and how collections are pursued. The designation of the guarantor helps medical providers understand who to hold accountable for outstanding balances, facilitating clearer communication regarding financial responsibilities.
