Key Components of CPT 99204 Documentation
The 2025 documentation requirements for CPT 99204 focus on two main selection factors:
- Medical Decision-Making (MDM) – Must be of moderate complexity
- Time – Total time spent must be 45-59 minutes on the date of service
Let’s break down each component in detail:
Medical Decision-Making Requirements
To qualify as moderate complexity MDM, your documentation must demonstrate at least two of these three elements:
- Number of Diagnoses or Management Options: Multiple problems requiring extensive evaluation
- Amount and/or Complexity of Data: Moderate amount of data to be reviewed and analyzed
- Risk of Complications: Moderate risk of complications, morbidity, or mortality
Time-Based Documentation
If you’re selecting 99204 based on time, remember these key points:
- Total time must be 45-59 minutes
- Time includes both face-to-face and non-face-to-face activities on the day of service
- Activities like reviewing records, ordering tests, documenting, and communicating with other providers all count
Pro Tip: Always clearly document the total time spent in your notes with a statement like: “Total time spent on this encounter: 52 minutes, including review of lab results, comprehensive examination, discussion of treatment options, and coordination of care.”
Comprehensive History and Examination Documentation
While the 2021 E/M guideline changes reduced the emphasis on history and physical exam elements, providing a medically appropriate history and exam remains essential for good patient care and supporting your medical decision-making.
For a thorough 99204 documentation, consider including:
Patient History Elements
- Chief Complaint: Clear documentation of the reason for the visit
- History of Present Illness (HPI): Detailed description of symptoms, duration, severity
- Review of Systems (ROS): Documentation across multiple body systems
- Past Medical, Family, and Social History: Comprehensive documentation
Physical Examination
- Comprehensive approach: Examination of multiple organ systems
- Findings documentation: Clear documentation of both positive and negative findings
- Relevance to chief complaint: Focus on areas related to the presenting problem
Common Documentation Pitfalls to Avoid
Many healthcare providers make these documentation mistakes that can lead to claim denials:
- Insufficient MDM documentation: Failing to show the complexity of your medical decision-making
- Missing time documentation: Not clearly stating the total time spent when using time-based coding
- Using templates without customization: Copy-paste documentation without patient-specific details
- Downcoding out of fear: Selecting lower codes when documentation supports 99204
Comparison: 99203 vs. 99204 vs. 99205
Understanding the differences between these codes is crucial for proper selection:
| Code | MDM Level | Time (minutes) | 2025 Medicare Reimbursement |
| 99203 | Low | 30-44 | $112.84 |
| 99204 | Moderate | 45-59 | $167.10 |
