E&M With Injection: What If We Want to Code Based on Time?

Question:

We have a recent case where a patient returned with return of pain about five months after a previous injection. The physician evaluates the patient noting no new injury, no changes in his exam findings and decides to re-inject the patient’s knee without additional treatment options discussed. We shared with the physician that the E&M was not separately reportable. The physician asked, ‘what if I code based on time, is it reportable then?” We are unsure if this makes a difference or not. Will you address this question?

Answer:

KZA agrees with your initial recommendation based on the information provided. In terms of your specific question, whether the rules associated with modifier 25 (significant, separate service) vary based on the methodology supporting a level of service, the answer is “no”.

The E&M guidelines address how to select a level of service based on either MDM (Medical Decision Making) or Time. The rules associated with modifier 25 are specific to the E&M meeting the significant separate service rules, not the methodology of E&M code selection. In the scenario provided, the significant separate services rules are not met; report the injection and drugs, as appropriate.
