Understanding Key Medical Billing Codes and Practices: A Guide for Patients and Providers
-
Healthcare billing can be a confusing maze of codes and terminology, but understanding even a few basics can help you make informed choices and avoid unnecessary costs. Let’s take a look at some key elements—ranging from CPT coding to POS identifiers—and also shine a light on an issue many patients may not be aware of: unethical billing practices in US healthcare.
One essential code to know is the CPT code for mental health assessment. When a patient undergoes an initial psychiatric evaluation—typically for diagnostic purposes without medication—the code most commonly used is 90791. This code is reserved for in-depth assessments of a patient’s mental health status and treatment planning. If medical services or medication management is also involved, 90792 is often used instead. Accurate use of these codes, along with clear documentation, is crucial for both compliance and timely reimbursement.
Another critical part of the billing puzzle is POS codes—short for Place of Service. For example, what is POS 11? It refers to services delivered in a physician’s office. It might sound simple, but using the wrong POS code—like billing for office services when they were actually rendered via telehealth or in an outpatient hospital setting—can cause insurance denials or audits. Proper use of POS 11 helps practices stay in line with payer requirements and ensures proper payment.
That brings us to a growing concern across the medical field: unethical billing practices in US healthcare. These might include upcoding (billing for more complex services than were provided), unbundling (billing separately for procedures that should be grouped), or billing for services not rendered. These practices not only burden patients with unfair costs but also increase premiums and damage trust in the healthcare system. It's important for both providers and patients to monitor billing details and ask questions when something doesn’t look right.
Whether you're a provider looking to bill more accurately or a patient seeking transparency in your medical expenses, awareness of these codes and practices is a vital first step. Let’s keep this thread going—share your experiences, ask questions, or post tips on how you’ve dealt with confusing or questionable medical billing.
