You just spent 23 minutes counseling a new mom on postpartum depression, meds, and lactation. You feel it’s a 99214—but can you prove it?

In 2025, time-based E/M billing is the safety net when MDM doesn’t hit the mark. But the old “8-minute rule” from therapy doesn’t apply—CPT has its own thresholds. Get it wrong, and you’re downcoded or audited.

Here’s the 2025 cheat sheet for tracking time on 99202–99215, plus how mid-market practices are using AI to make it effortless.

2025 Time Thresholds: Know Before You Bill

Pro tip: You only need >50% counseling/coordination to use time. Document it.

How to Document Time

“Total face-to-face time: 42 minutes. Greater than 50% spent in counseling and care coordination: reviewed labs, adjusted insulin, discussed stroke risk, coordinated with endo, and educated on CGM use.”

That’s it. One sentence = 99215.

The 8-Minute Rule Myth—Busted

Don’t mix them up—payers will.

4 Time-Tracking Hacks for Busy Clinics

1. Use “Start/Stop” in Your EHR

Epic, Cerner, and athena let you clock in/out per encounter. Train MAs to start timer at rooming.

2. Let AI Do the Math

Ambient AI scribes auto-capture:

• “Provider entered room at 9:12 AM”
• “Exited at 9:47 AM”
• “32 min total, 18 min counseling” → flags 99214

3. Batch Counseling Notes

For chronic care (DM, HTN), use a macro:

“>50% time counseling on [diet/meds/compliance]. Total time: XX min.”

4. Audit Weekly

Pull 5 random 99214/99215s. Check:

• Time documented?
• 50% counseling stated?
• Matches EHR timestamp?

Real-World Example: 99215 via Time

S: 68 y/o with DM2, new A1c 9.8, foot numbness

O: BP 148/92, monofilament 3/10 bilat

A/P: 

- Start dulaglutide, hold metformin (eGFR 42)

- Podiatry referral, diabetic shoes

- 45 min total: 28 min counseling on injection training, foot care, hypoglycemia risk

Result: 99215, no MDM debate.

Red Flags That Trigger Audits

‍

Time-based E/M is your audit shield—but only if you document the minutes and the >50% counseling. AI makes it automatic; you just review.
