• Moderate complexity in medical decision-making (MDM)
• A medically appropriate history and/or examination

Billing Guidelines for CPT Code 99204

To successfully bill CPT 99204, it’s important to ensure that all documentation requirements are met. Here’s a breakdown of the essential elements:

1. Patient History: The documentation should reflect a comprehensive history of present illness (HPI), including a review of systems (ROS).

3. Medical Decision-Making (MDM): MDM should reflect moderate complexity, involving the management of multiple conditions, a review of tests, or a moderate risk of complications.
4. Time Spent: If time is used to determine code selection, ensure that 45-59 minutes are spent face-to-face with the patient, including all related counseling and care coordination. It is important to note that the time includes: reviewing the chart, the actual face to face with the patient, and all the time you spend after the visit on documentation, reviewing studies, calling the patient or family as long as it is done before midnight on the same day of service.
5. Counseling/Coordination: If more than half of the time is spent on counseling or care coordination, this must be documented explicitly.
6. Signature: The provider must authenticate the documentation with a signature.

Avoiding Common Mistakes with CPT 99204

Here are some common mistakes that healthcare providers should avoid:

• Inadequate Documentation: Failure to fully document the comprehensive history or physical examination may lead to downcoding.
• Incorrect Time: Ensure that the total time spent is clearly noted in the documentation,if using time as the code selection criterion.
• Misclassification of Patient Complexity: Be sure the medical decision-making reflects moderate complexity. Underestimating the complexity can lead to underbilling.
• Using CPT 99204 for Established Patients: This code is strictly for new patients. Established patients should use a different E/M code.
• Coding 99204: Since selecting CPT is considered a responsibility of the provider, we recommend that the correct  CPT be documented in the medical record.
