Medicaid guidelines
According to Medicaid guidelines, a separate E/M can be billed in addition to the health check if additional work needed to be done aside from the health check and the condition(s) was/were severe enough to justify this separate work, but you can only charge a level 1 (99211) or 2 (99212) for established patients, level 2 is the highest level, in additional to your reported health check, or for a new patient a level 1 (99201).
We also were advised that in the medical record it should be clearly defined what the additional workup entailed and we either should create a separate office note or, if documentating in the encounter note for the health check, have a separate section, i.e. at the bottom of the health check section, where everything regarding the sick encounter is listed and what was done.
Hope this helps!
