When to Use a Modifier with 99214

You should apply a modifier if:

• You’re billing 99214 with a psychotherapy code like 90833 → Use Modifier 25.
• You perform a procedure on the same day as the E/M service → Use Modifier 25.
• The service was unrelated to a previous visit (e.g., post-op complication) → Use Modifier 24 (if applicable).

Common Modifiers for 99214

Modifier	Description	Example Use Case
25	Significant, separately identifiable E/M service	Billing 99214 and 90833 together
24	Unrelated E/M by same provider during post-op	Follow-up for a new issue during global period
57	Decision for surgery	Used with E/M that leads to surgery next day

Why Modifier 25 is So Important

Modifier 25 is often used incorrectly or not at all, leading to claim denials or underpayments. Always ensure the E/M service is separate and well-documented to justify its use.

---

Documentation Tips

• Separate the E/M portion from any other procedure notes.
• Clearly state that both services were medically necessary.
• Note time spent and actions taken for each service.

---

Avoid These Mistakes

• Using a modifier without justification.
• Forgetting to use a modifier when required.
• Assuming all visits need a modifier — not always true.

Conclusion

CPT 99214 may need a modifier in certain situations, especially when billed with additional services like psychotherapy. Using the right modifier—especially Modifier 25—can mean the difference between full payment and a denial.
