CPT® Code 99343 is used to report evaluation and management (E/M) services provided in a patient’s home for a new patient presenting with moderate to high severity conditions. These visits typically involve a comprehensive assessment, detailed medical decision-making, and extended face-to-face time that is approximately 45 minutes.
This code reflects the complexity and intensity of delivering care in a home setting, often for patients with mobility limitations, chronic illness, or acute conditions requiring in-home evaluation.

Documentation Requirements

- Detailed or comprehensive examination findings
- Medical decision-making complexity (moderate or high)
- Total time spent (if billing based on time)
- Assessment, diagnoses, and treatment plan
- Provider signature and credentials
Accurate documentation is essential to demonstrate the complexity of care and support appropriate reimbursement.
Reimbursement and Coding Considerations
- CPT 99343 is typically reimbursed when medical necessity is established
- Must meet new patient criteria (no professional services from the provider/group within the past 3 years)
- Documentation should clearly support moderate to high severity and complexity
- Time-based billing may be used if properly documented
- Place of service (POS) must reflect home setting
- May be billed alongside separately identifiable services when appropriate and compliant
Always verify payer-specific guidelines, as coverage and documentation requirements may vary.
