If you’re not fully capturing your provider time, you’re leaving revenue on the table—and increasing compliance risk.

That means your documentation must reflect the total time you spend managing care, not just what happens in the exam room. When you apply time-based coding correctly, you can often justify higher-level codes—especially in complex cases.

But here’s the catch: if you don’t understand how to handle scenarios like next-day results or encounters that cross midnight, you risk underbilling, denials, or audits.

What Counts as Billable Time in E/M Coding

To code accurately, you need to understand exactly what time you can include. According to guidance supported by American Medical Association and CMS, billable time includes all medically necessary work performed on the date of service.

You can count time spent on:

• Reviewing medical records and prior results
• Seeing and counseling the patient
• Coordinating care with other providers
• Documenting in the EHR
• Ordering tests, prescriptions, or referrals

The key rule: only time spent by the physician or qualified healthcare provider counts—not your staff.

If you’re not tracking this consistently, your coding is likely undervaluing your services.

Next-Day Results: Are You Missing Billable Work?

One of the most commonly missed opportunities in medical billing is next-day results review.

What this means for your practice

If you review lab, imaging, or pathology results on a different day than the visit, that time does NOT roll into the original encounter. Instead, it can be treated as a separate, billable service—if documented correctly.

Example in real practice terms

You see a patient Monday and order labs. On Tuesday, you:

• Review results
• Interpret findings
• Adjust treatment
• Communicate with the patient

That time is new work performed on Tuesday—and it can support billing.

What you need to document

To protect your revenue and compliance, your documentation should include:

• When results were received
• Time spent reviewing them
• Your clinical interpretation
• Actions taken (med changes, follow-ups, referrals)

Without this level of detail, payers may deny the claim or question medical necessity.

Previous Day Encounters: When Care Crosses Midnight

Encounters that span two calendar days can easily create confusion—and billing errors.

What counts as a “previous day encounter”

This happens when you begin treating a patient on one day and continue care after midnight. This is common in:

• Emergency departments
• Observation care
• Extended outpatient services

How to code it correctly

• Time is tied to the date the service begins
• You must track time continuously across both days
• Documentation must clearly show ongoing care without interruption

Where practices go wrong

Many practices:

• Split time incorrectly
• Miss hours of care
• Fail to document continuity

That leads directly to lost revenue or compliance issues.

How to Document Time So You Get Paid (and Stay Compliant)

Your documentation is your first line of defense in an audit—especially under scrutiny from U.S. Department of Health and Human Services.

Best practices you should implement immediately

• Use exact time stamps (start/stop times)
• Clearly describe what you did (not just “reviewed labs”)
• Tie every activity to medical necessity
• Use structured EHR fields—not just free text

Strong example

Instead of writing:
“Reviewed labs”

Write:
“9:15–9:35 AM: Reviewed CMP and CBC. Identified elevated potassium (6.2). Consulted nephrology and adjusted medication plan.”

That level of detail protects your claim—and your revenue.

Workflow Fixes That Improve Accuracy and Revenue

If your providers are trying to remember time at the end of the day, your system is already broken.

What works better

• Use EHR timers or prompts
• Train providers to log time immediately after tasks
• Create standardized documentation templates
• Align coding and clinical teams on expectations

When your workflow supports real-time tracking, your coding becomes more accurate—and more profitable.

Common Mistakes That Cost Your Practice Money

If you want to tighten your revenue cycle, watch for these:

1. Double counting time

You cannot bill the same time under multiple services. Keep encounters clearly separated.

2. Missing post-encounter work

If your providers review results later and don’t log time, that revenue is gone.

3. Weak documentation

Vague notes = denied claims.

4. Lack of provider education

If your providers don’t understand time-based coding, your billing team can’t fix it later.

How to Protect Your Practice from Audits and Denials

Time-based coding is under increasing scrutiny. That means you need to be proactive.

What you should be doing

• Conduct regular internal audits
• Review high-risk scenarios (like next-day results)
• Train providers quarterly on documentation updates
• Monitor payer feedback and denial patterns

Accurate documentation doesn’t just help you get paid—it protects you from recoupments.

Key Takeaways for Your Practice

If you want to improve revenue and reduce risk, focus on these:

• Capture all provider time, not just visits
• Treat next-day work as separate billable activity
• Track time carefully for multi-day encounters
• Document clearly, specifically, and consistently
• Build workflows that support real-time time tracking

When you do this right, your coding reflects the true value of your care.
