I have a chart where a patient came in to f/u on HTN, hyperlipidemia, and obesity. Pt is also concerned about swelling of her elbow, but the provider states her elbow is fine and also wants to code Z71.1. I thought Z71.1 was a stand alone code that meant there are no complaints or any other dx to code. To me I would code the HTN, Hyperlipidemia, and Obesity and not code anything about the elbow. Is this correct?
