I have a provider who see's patients for preventive visits and always adds an E/M to the visit. If he discusses anything other than what is in the preventive visit (like HBP, or Med refill) he will add an E/M to the visit. What is the rule for that? Also he codes based on time now. Like shoulder pain and leg stiffness he will code a 99215 due to how much time he spends with the patient. MDM is moderate. Anyway, does anyone know where I can find detailed info on upcoding?
