How will the medical staff know which diagnosis is primary secondary etc for the patient?

Medical staff determine the primary and secondary diagnoses by evaluating the patient's medical history, symptoms, and results from diagnostic tests. The primary diagnosis is typically the main condition responsible for the patient's visit, while secondary diagnoses are additional conditions that may affect treatment or management. This classification is guided by clinical guidelines and coding systems like ICD-10, which help ensure accurate documentation and billing. Regular interdisciplinary discussions and reviews also aid in clarifying these diagnoses.
