Blood testing done for routine general physical exam

Many of our patients now have Insurance plans that cover Preventative Health coverage at 100%. There is an ICD 9 code of V72.62 which is Laboratory examination ordered as part of a routine general medical examination. Can you provide any clarity on what lab testing would be covered utilizing this code?

I don't use it since I do all my labs at the visit but

you could use it for labs done prior to a visit for a V70.0 physical. The only reason I could see to use it is that it would allow the insurer to know that it was a visit for just a lab and not an exam (although the CPT should tell them that.) I have seen insurers that cover preventive at 100% but only one visit per year, so hopefuly the V72.62 will not count as that visit.
