CPT Code 99285: Emergency Department Visit, High Complexity

What is CPT code 99285?

CPT code 99285 refers to a high-level emergency department visit that involves services provided by qualified health care professionals for a new or established patient. This code is typically used when the patient presents with a condition that poses an immediate, significant threat to life or bodily function, necessitating prompt medical attention.

To appropriately use CPT 99285, healthcare providers assess the patient through a comprehensive history, a comprehensive examination, and high-complexity medical decision-making. According to the coding guidelines set by the American Medical Association, the medical decision-making must involve extensive diagnostic tests or a situation involving an extended period of time due to the patient’s condition (American Medical Association, 2023).

This emergency department service is commonly used under the Outpatient Prospective Payment System (OPPS) and supports documentation that captures detailed and complex patient evaluations. These visits may also involve multiple system assessments and procedures across emergency department services and, depending on the acuity, even multiple encounters.

Healthcare providers must select the appropriate code based on the severity and complexity of the patient’s condition and the extent of care provided. This ensures accurate reporting and reimbursement for services delivered in emergency department settings.

CPT code 99285 documentation requirements

To bill CPT Code 99285 correctly, documentation must support high-complexity care in the emergency department. Below are the key requirements:

• Comprehensive history and physical examination must be documented.
• Medical decision-making must be of high complexity.
• The patient’s condition should require urgent evaluation due to a potential immediate significant threat to life or bodily function.

The visit may involve multiple prescription medications, patients with difficulty understanding instructions, or in-depth discussions, such as explaining a wound infection.

While CPT code 99285 typically reflects high-acuity cases, it may apply to patients with low to moderate severity if the situation is resource-intensive or complex. Qualified healthcare professionals or other providers must provide care, and documentation should align with current procedural terminology standards used to define higher-level emergency department services.

CPT code 99285 billing guidelines

When billing for CPT code 99285, it is essential to follow specific billing guidelines to ensure accurate reimbursement. For a patient involving multiple encounters for the same concern, additional documentation may be required to support the need for follow-up care. Comprehensive patient care must be well-documented, reflecting all services rendered during the visit.

Billing for CPT code 99285 is often done on a variable intensity basis, where the level of service can change depending on the patient’s needs and urgency. The medical record must fully reflect the patient’s condition and the decisions made during patient management, demonstrating the complexity of the care provided. If the patient demonstrates understanding quickly, it may influence the level of documentation, especially in cases where instructions regarding treatment are provided.

Facility codes must be used accurately with CPT code 99285 to indicate the appropriate setting for the services. Following these guidelines ensures that the billing process aligns with industry standards, enabling proper reimbursement for emergency department services.
