99213 is appropriate based on the information you indicated.
You need two out of three levels for an Established patient visit... if you have an Expanded HPI, a Prob. Pert. Exam, and a Moderate or High MDM ...you are still at 99213 level or service.
To bill the 99214 you'd need a HPI or Exam level at Detailed. to add to the Moderate or High MDM. You are not indicating you have documentation to support a Detailed level of HPI or Exam....so, 99213 is the best you can do with the documentation you have.
