Answer :
When assigning CPT and ICD-10-CM codes for a 13-year-old patient with food poisoning, the appropriate E & M level code such as 99203 or 99204 will be used along with ICD-10-CM codes from the T62-T65 range, reflecting the diagnosis and treatment provided.
When a 13-year-old patient presents with abdominal pain, nausea, and vomiting, and is diagnosed with food poisoning after a physician's office encounter, a medical coder will need to assign the appropriate CPT E & M level for the office visit, any relevant procedures, and ICD-10-CM code(s) for the diagnosis. Since the patient is a new patient, the E & M level will reflect a comprehensive history and examination .
