CPT Code Overview
CPT 81436 is a code used for genetic testing services, typically performed in a laboratory setting (POS 81). This code has been marked for deletion effective December 31, 2024. Genetic testing plays a critical role in identifying hereditary conditions and informing clinical decision-making. Laboratories specializing in medical genetics utilize this code to bill for advanced genetic analyses that support patient diagnosis and management. The deletion of CPT 81436 signals a significant change in coding practices for genetic testing services.
Clinical & Coding Specifications
Clinical Context
A patient presents with a personal or family history suggestive of hereditary cancer syndromes, such as colorectal or endometrial cancer. The ordering physician, typically a specialist in medical genetics, requests comprehensive genetic testing to identify potential pathogenic variants associated with these malignancies. The procedure is performed in a laboratory setting (Place of Service 81), where advanced molecular techniques are used to analyze the patient's DNA. The results inform clinical management, including risk assessment and potential targeted therapies.
