CPT Code 99309: Subsequent Nursing Facility Visit, Moderate Complexity

CPT codes 99308 and 99309 represent different levels of subsequent nursing facility care. Code 99308 is for low-level complexity of medical decision making, including an interval history and brief examination. Code 99309 is for moderate-complexity visits, requiring a detailed interval history, a comprehensive examination, and possible adjustments to the care plan. The key difference lies in the detail and complexity of the history, examination, and medical decision-making involved in the patient's care.

CPT code 99309 is typically associated with 30 minutes of face-to-face time with the patient.

For initial nursing facility care, CPT code 99306 is used for high-complexity assessments. For subsequent nursing facility care, 99310 is for very high-complexity visits for unstable patients requiring intensive services. The specific code depends on whether it's an initial assessment or a follow-up visit.
