When Is CPT Code 99214 Used?

CPT 99214 is used for established patient visits where the visit involves more complexity than a routine follow-up but does not reach a high complexity level.

It is commonly used when:

• Medication management is involved

This code reflects a visit that requires clinical judgment and careful evaluation.

Under current E/M guidelines, CPT 99214 can be selected based on total time.

• 30 to 39 minutes
• Time includes both face-to-face and non face-to-face work
• Applies only to work done on the date of the visit

Time must be documented clearly if time is used as the selection method.

Medical Decision Making for 99214

If billing is not based on time, CPT 99214 is selected based on moderate medical decision making.

This includes:
