What do P codes represent in billing?

P codes represent pathology and laboratory services in billing. These codes are part of the system used to categorize and identify specific medical services and procedures for billing and reimbursement purposes, particularly in healthcare settings. By using P codes, healthcare providers can accurately document laboratory tests and related procedures, ensuring that they receive appropriate compensation for the services rendered. This classification helps streamline the billing process, facilitates proper coding, and aids in the communication of services among healthcare providers, insurers, and governmental agencies.

The other choices pertain to different types of codes or categories within the expansive medical coding system and do not accurately describe what P codes signify. Understanding the specific role of P codes is essential for effective billing and coding practices in a medical administrative role.
