Naturopathic medicine is becoming more popular across the United States. More patients now seek preventive and holistic care. As naturopathic practices grow, correct medical billing becomes very important. CPT codes help describe the services provided during patient visits.
Insurance companies use these codes to decide payment. Using the correct CPT codes helps naturopathic doctors avoid claim denials, delays, and payment issues.
This blog explains the most commonly used CPT codes across naturopathic practices in the United States and how they are typically applied in everyday clinical settings.
Understanding CPT Codes in Naturopathic Billing
The naturopathic code was developed by the American Medical Association in 1966. These codes are used by all healthcare providers, including naturopathic doctors, to report services on insurance claims.
While CPT codes are the same across providers, insurance coverage for naturopathic services varies by state laws and payer policies. Some insurers fully cover naturopathic services, while others offer limited coverage. Even when coverage is restricted, accurate CPT coding is still required for proper documentation and compliance.
Correct CPT coding reflects the complexity of care, time spent with patients, and services provided. It also supports medical necessity, which is a key factor in claim approval.
Office Visit CPT Codes for Established Patients
Office visits are the most common services billed by naturopathic practices. These visits usually involve evaluation, assessment, and ongoing management of patient conditions.
CPT 99214 Established Patient Office Visit
CPT code 99214 is used for moderate-complexity established patient visits. This code applies when the provider manages multiple conditions or addresses one condition that requires detailed evaluation and planning.
In naturopathic care, this may include reviewing lab results, adjusting supplements, managing chronic conditions, or updating lifestyle recommendations. Documentation must clearly show medical decision-making and patient assessment.
CPT 99215 High-Complexity Office Visit
CPT code 99215 is used for high-complexity established patient visits. These visits involve advanced decision-making, multiple health issues, or significant risk factors.
This code is often appropriate for patients with complex chronic illnesses, multiple system concerns, or extensive care planning needs. Clear documentation of complexity and time spent is critical.
Preventive Medicine Counseling and Wellness Services
Preventive care is a core focus of naturopathic medicine. Many services aim to reduce disease risk and support long-term health.
CPT 99401 Preventive Medicine Counseling
CPT code 99401 is used for individual preventive counseling services. These sessions focus on health education, lifestyle changes, nutrition guidance, stress management, and disease prevention.
The counseling must be preventive in nature and properly documented, including the time spent and topics discussed. This code is commonly used in wellness-focused visits.
CPT 99395 and CPT 99396 Preventive Medicine Visits
Preventive medicine visit codes are used for routine wellness exams rather than problem-focused visits.
CPT 99395 applies to patients aged 18 to 39 years.
CPT 99396 applies to patients aged 40 to 64 years.
These visits include a comprehensive health history, risk assessment, preventive screenings, and counseling. They must be billed separately from problem-oriented visits.
Visit Complexity Add-On Code
CPT G2211 Visit Complexity Add-On
G2211 is an add-on code used with certain evaluation and management visits. It reflects the ongoing complexity of care related to long-term patient relationships or chronic condition management.
This code is often relevant in naturopathic practices where providers manage patients over extended periods. G2211 cannot be billed alone and must be attached to an eligible office visit code.
Laboratory and Specimen Collection Services
Laboratory testing is frequently used in naturopathic medicine to assess nutritional status, hormone levels, and metabolic function.
CPT 36415 Collection of Venous Blood
CPT code 36415 is used for venous blood collection performed in the office. This code only represents the blood draw, not the laboratory testing itself.
Documentation should confirm that venipuncture was performed. Some insurance plans bundle this service, so payer guidelines should always be reviewed.
Chronic Care Management Services
Chronic care management supports patients with long-term health conditions and ongoing care needs.
CPT 99491 Chronic Care Management
CPT code 99491 is used for chronic care management services provided by a physician or qualified healthcare professional. It requires at least 30 minutes of care management services in a calendar month.
Services may include care coordination, treatment planning, medication management, and communication with other providers involved in the patient’s care.
CPT 99417 Prolonged Office Services
CPT code 99417 is used when an office visit exceeds the typical time associated with the primary E/M code. It must be billed in addition to a qualifying office visit.
Accurate time tracking and documentation are required to support this code.
Prolonged Services Without Direct Patient Contact
CPT 99358 Prolonged Non Face-to-Face Services
CPT code 99358 is used for prolonged services that occur without direct patient contact. This may include reviewing extensive medical records, developing complex care plans, or coordinating care with other providers.
This code requires a minimum time commitment and detailed documentation of the work performed.
Behavioral and Mental Health Services
Naturopathic practices often address emotional and behavioral health as part of whole-person care.
CPT 90833 – Psychotherapy with Evaluation and Management
CPT code 90833 is used when psychotherapy is provided along with an E/M service. The psychotherapy portion must meet time requirements and be distinct from the medical evaluation.
Both services must be documented separately for billing purposes.
CPT 96127 Brief Emotional or Behavioral Assessment
CPT code 96127 is used for brief standardized assessments of emotional or behavioral health. These may include screenings for depression, anxiety, or other mental health concerns.
Multiple units may be billed depending on the number of assessment tools used, subject to payer rules.
Preventive Screening Services
CPT G0442 Annual Alcohol Misuse Screening
G0442 is used for annual alcohol misuse screening for eligible patients. This code is commonly associated with preventive services and must follow payer-specific guidelines.
This screening supports early identification of risky behaviors and aligns with preventive care goals.
Minor In-Office Procedures
Some naturopathic doctors perform minor procedures within their scope of practice.
CPT 11401 Excision of Benign Skin Lesion
CPT code 11401 is used for the excision of a benign skin lesion within a specific size range. Documentation must include the size, location, and nature of the lesion.
If pathology services are required, they are billed separately.
After-Hours Services
CPT 99050 After-Hours Service
CPT code 99050 is used when services are provided outside normal office hours, such as evenings, weekends, or holidays. While not all insurance companies reimburse this code, it documents additional provider effort and patient access.
Documentation and Billing Considerations
Proper documentation is essential for successful billing. Each CPT code must be supported by clear clinical notes that reflect the service provided, time spent, and medical necessity.
Naturopathic practices should regularly review payer policies, as coverage rules vary widely. Using accurate diagnosis codes, appropriate modifiers, and correct coding combinations helps reduce denials and audits.
Billing staff and providers should work together to ensure services are coded correctly and consistently.
Conclusion
Using the correct CPT codes is critical for naturopathic practices operating in the United States. Accurate coding supports timely reimbursement, reduces claim denials, and ensures compliance with insurance requirements.
As demand for naturopathic care continues to grow, understanding and applying standard CPT codes will remain essential to running a successful practice. Strong documentation and informed billing practices help protect both providers and patients.
