Your combination of codes does not make sense.
you have a patient with multiple open wounds, unspecified, with an unspecified disorder of lipid metabolism , with unspecifed hypertension, and nervousness, then you want to code for an AWV, a level 4 visit and a neuro status behavioral exam. If the patient had an AWV then you use a V70.0 first listed, IF documentation can support then a separate exam for other reasons then you can POSSIBLY have the level 4 but if the patient indeed had multiple open wounds, the wounds will have precedence and you will need to reschedule the AWV and the mini mental exam. If this was due to a suicidal attempt then you need some other codes.
As far as using the 300.xx codes , yes they can be used but be certain the patient has actually been diagnosed with this condition, if so then you cannot use the 799.2x instead. some payers will not pay a family practice physician if a 300.xx code is first list, but then that does not make it an incorrect dx, it depends on the documentation.
The codes you have supplied however paint an illogical picture for an encounter. perhaps you could post the note.
