It is a frustrating scenario: You see a patient for a significant amount of time, managing both their medical needs and providing psychotherapy. You bill an established office visit (99214) along with the psychotherapy add-on (90833).
But instead of payment, you get a denial stating "insufficient visit length" or "overlapping time." Why does this happen when you know you spent plenty of time with the patient?
The answer usually lies in how you are counting the minutes.
The "Double-Dipping" Problem
To understand the rejection, we have to look at the math the insurance company is using.
- Code 90833 (Psychotherapy) is a time-based code. It requires a minimum of 16 minutes dedicated strictly to therapy.
- Code 99214 (Office Visit) requires 30-39 minutes if you are billing based on time.
The Mistake:
Many providers look at the clock, see the total visit lasted 40 minutes, and try to bill both codes. However, you cannot count the same minutes twice.
If you subtract the 16 minutes required for the therapy (90833) from your total 40 minutes, you only have 24 minutes left for the office visit. That is not enough time to justify a 99214 (which needs 30), so the claim gets rejected.
The Fix:
Switch to "Medical Decision Making".
You don't always need "more time" to get paid. You just need to change how you select the office visit level.
For the 99214, you have two options for selection:
- Time: (Requires 30+ separate minutes)
- Medical Decision Making (MDM): (Requires Moderate Complexity)
The Solution
Stop billing the 99214 based on time. Instead, document the Medical Decision Making.
If the patient has a chronic condition that is not at goal, or an acute illness that requires prescription management, you likely meet the criteria for "Moderate Complexity" (99214) regardless of how many minutes it took.
Summary for Success
- Carve out the therapy time: Set aside the minutes used for 90833.
- Look at the remainder: If the remaining time is short, do not use time to select your E/M code.
- Use MDM: Base your 99214 on the complexity of the medical problem, not the clock.
