Chapter 22B provides practice coding ICD-10-CM Chapter 19 codes

Chapter 22B provides practice coding ICD-10-CM Chapter 19 codes. External cause codes will be discussed and coded in Chapter 23. For Chapter 22B, assign only diagnosis codes, not external cause of morbidity (V–Y) codes. A college-age male was brought to the emergency department by ambulance called by his friends after they were unable to wake him this morning. The patient now responds to commands but is very drowsy. Based on the history provided by friends, the patient was drinking heavily last night and was seen taking a handful of pills that were later determined to be Naproxen (Naprosyn) because the patient said he had a headache. After receiving IV fluids and being placed on telemetry, the patient became more alert and confirmed the history told by his friends. The ER physician discharged the patient with the final diagnosis of drowsiness due to the interaction of alcohol and naproxen.
