I would likely consider this 99214 as well, for problems and risk with the limited information provided. Not sure what you're referencing here about rash???? Original post stated 2 chronic stable problems addressed (DM & HTN) = moderate problem. Prescription management = moderate risk
If what you are asking is whether the level you get from problems has to be the same problems that you are leveling for risk, the answer to that is no. I would also imagine if the provider is actually addressing the DM & HTN, there is likely prescription management for that as well. But it does all depend on the documentation. It can't be a situation where the patient is going to the provider due to the sore throat and the provider just mentions - HTN stable. They have to address/treat the problem. Just like listing the patient's medications doesn't count as prescription management.
The AMA guidelines are the best reference.
