Which of the following is an example of a write-off?

A professional courtesy discount is a clear example of a write-off because it represents a reduction in the fees that a healthcare provider typically charges. In this context, a write-off occurs when a provider decides not to collect a portion of the payment owed. This could be due to various reasons, including maintaining good relationships with other professionals or providing services to those in the field at a reduced rate.

Write-offs are commonly applied in medical billing to account for discounts or adjustments that lower the amount that is ultimately claimed for payment. This practice helps to reflect the true financial relationship between the provider and their colleagues or patients who are financially unable to pay the full amount.

In contrast, the other options do not meet the criteria of a write-off. A professional account receivable refers to the amount owed to a healthcare provider for services rendered, not a discount or reduction of income. The cost of damaged items might represent a loss for the practice but is not classified as a write-off in billing terms. Similarly, a patient's account payable indicates the amount the patient owes and does not pertain to the write-off process.
