CPT Code 99396: Preventive Medicine Visit

Introduction to CPT Code 99396 Description

CPT code 99396 is a procedural code used in medical billing to describe a preventive medicine evaluation and management (E/M) service for an established patient, typically an annual wellness visit or physical examination for adults aged 40–64 years. This code is part of the Current Procedural Terminology (CPT) system maintained by the American Medical Association (AMA) and is widely used in primary care and family practice settings to promote health maintenance and disease prevention. Understanding the CPT code 99396 description is essential for physicians, healthcare providers, and billing professionals to ensure accurate billing and avoid issues that lead to claim denials.

This guide provides a detailed overview of CPT code 99396, its applications, modifiers, Medicare reimbursement rates, and strategies to optimize billing for preventive medicine services addressing health screenings and wellness care.

What is CPT Code 99396 and Preventive Medicine?

CPT code 99396 represents a preventive medicine service for an established patient aged 40–64 years, involving a comprehensive annual wellness visit or physical examination focused on health maintenance, risk factor assessment, and disease prevention. Unlike problem-oriented E/M codes (e.g., 99213), CPT code 99396 is used for routine, preventive care visits that do not primarily address acute or chronic illnesses, though minor issues may be addressed if time allows.

This code is typically used in primary care settings to:

• Assess the patient’s overall health status.
• Perform age-appropriate screenings (e.g., blood pressure, cholesterol, cancer screenings).
• Provide counseling on lifestyle factors (e.g., diet, exercise, smoking cessation).
• Update immunizations or recommend preventive measures.

CPT code 99396 is designed for established patients—those who have received professional services from the physician or another physician in the same group and specialty within the past three years—and is tailored to the 40–64 age group, reflecting the specific preventive needs of this demographic.

Procedure Involving CPT Code 99396

The procedure involving CPT code 99396 includes the following components, as defined by the AMA’s preventive medicine guidelines:

1. Comprehensive History: The physician collects a detailed medical, social, and family history, including risk factors, lifestyle habits, and preventive health needs.
2. Comprehensive Physical Examination: A thorough, age-appropriate physical exam is performed, covering multiple organ systems (e.g., cardiovascular, respiratory, musculoskeletal) to assess overall health.
3. Screening and Preventive Services: The physician orders or performs age- and gender-appropriate screenings, such as blood pressure checks, cholesterol tests, or cancer screenings (e.g., mammograms, colonoscopies).
4. Counseling and Education: The physician provides guidance on preventive measures, such as diet, exercise, smoking cessation, or immunizations, tailored to the patient’s risk profile.
5. Documentation: The physician documents the history, exam findings, screening results, counseling provided, and any preventive recommendations or follow-up plans.

The visit typically lasts 30–60 minutes, depending on the complexity of the patient’s preventive needs. CPT code 99396 is used in outpatient settings, such as a physician’s office or clinic, and may include telehealth visits when permitted by payers.

Comparison with Related CPT Codes

CPT code 99396 is part of the preventive medicine E/M code set, which varies based on patient status (new or established) and age group. Here’s how it compares to related codes:

• CPT Code 99386: Represents a preventive medicine visit for a new patient aged 40–64 years, unlike 99396 for established patients.
• CPT Code 99395: Covers a preventive medicine visit for an established patient aged 18–39 years, addressing a younger demographic.
• CPT Code 99397: Describes a preventive medicine visit for an established patient aged 65 years and older, tailored to older adults.
• CPT Code 99213: Represents a problem-oriented E/M visit for an established patient with low to moderate complexity, not a preventive visit like 99396.
• CPT Code G0439: Used for Medicare’s Annual Wellness Visit (AWV), distinct from 99396, which is not typically covered by Medicare for routine physicals.

Choosing the correct procedural code is critical to ensure accurate billing. For example, billing CPT code 99396 for a new patient (99386) or a problem-focused visit (99213) can lead to claim denials.

Modifiers for CPT Code 99396

Modifiers provide additional context for CPT code 99396 to ensure proper reimbursement. Common modifiers include:

• Modifier 25 (Significant, Separately Identifiable E/M Service): Used when a separate problem-oriented E/M service (e.g., CPT code 99213) is performed on the same day as the preventive visit to address a distinct medical issue. For example, managing hypertension during a wellness visit.
• Modifier 95 (Synchronous Telemedicine Service): Applied when CPT code 99396 is provided via telehealth, if permitted by the payer.
• Modifier 33 (Preventive Service): Indicates that the service is preventive, often used to ensure coverage under the Affordable Care Act (ACA) for eligible screenings.
• Modifier 59 (Distinct Procedural Service): Denotes a separate procedure on the same day, though less common with 99396. Use cautiously to avoid unbundling issues.
• Modifier 99 (Multiple Modifiers): Applied when multiple modifiers are needed.

Providers must follow AMA and payer guidelines, including Medicare’s National Correct Coding Initiative (NCCI) edits, to avoid errors that lead to claim denials. Note that Medicare typically does not cover CPT code 99396 for routine physicals, preferring codes like G0439 for Annual Wellness Visits.

Medicare Reimbursement Rates for CPT Code 99396

CPT code 99396 is generally not covered by Medicare for routine preventive physicals, as Medicare prioritizes specific preventive services under codes like G0438 (Initial Annual Wellness Visit) or G0439 (Subsequent Annual Wellness Visit). However, private payers and some Medicare Advantage plans may reimburse CPT code 99396. Key considerations include:

• Medicare Physician Fee Schedule (MPFS): If covered by a private payer, reimbursement rates for CPT code 99396 are based on the MPFS, adjusted by the Geographic Practice Cost Index (GPCI) for regional cost differences.
• Medicare Administrative Contractors (MACs): Regional MACs may provide guidance on coverage for preventive services under private plans or Medicare Advantage.
• Non-Facility vs. Facility Rates: Non-facility rates (e.g., private offices) are higher to account for overhead costs, while facility rates (e.g., hospital outpatient clinics) are lower.
• Telehealth Eligibility: Some private payers may cover CPT code 99396 for telehealth visits, depending on 2025 coverage policies.

To verify reimbursement rates for 2025, providers should:

1. Check the MPFS on the Centers for Medicare & Medicaid Services (CMS) website for private payer rates.
2. Consult their payer contracts or regional MAC for specific coverage policies.
3. Use coding tools like AAPC Coder or Kareo for rate estimates.

Accurate documentation of preventive services, such as screenings, counseling, or immunizations, is critical for reimbursement by private payers or Medicare Advantage plans.

Conditions and Services Addressed with CPT Code 99396

CPT code 99396 is used for preventive medicine services aimed at health maintenance and disease prevention in adults aged 40–64 years. Services and conditions addressed include:

• Health Screenings: Blood pressure checks, cholesterol screening, colorectal cancer screening, mammograms, or prostate cancer screening.
• Immunizations: Administering or recommending vaccines, such as influenza, pneumococcal, or shingles vaccines.
• Lifestyle Counseling: Guidance on diet, exercise, smoking cessation, alcohol use, or stress management to reduce risk factors.
• Chronic Disease Risk Assessment: Evaluating risks for conditions like hypertension, diabetes, heart disease, or obesity.
• Minor Problem Management: Addressing minor acute or stable chronic issues (e.g., mild allergies or controlled hypertension) if time permits, though significant issues may require a separate E/M code like 99213.

The focus of CPT code 99396 is on proactive health maintenance, not the treatment of acute or complex chronic conditions, distinguishing it from problem-oriented visits.

Medical Billing Best Practices to Ensure Accurate Billing

To ensure accurate billing for CPT code 99396 and minimize issues that lead to claim denials, providers should adopt the following medical billing strategies:

1. Train Staff: Educate billing staff on the CPT code 99396 description, its differences from other preventive codes (99395, 99397) or problem-oriented codes (99213), and appropriate modifiers.
2. Use EHR Systems: Electronic health records like Epic, Cerner, or eClinicalWorks streamline documentation and coding for preventive medicine visits.
3. Document Preventive Services: Clearly note the history, exam, screenings, counseling, and preventive recommendations to justify 99396.
4. Verify Payer Guidelines: Confirm Medicare, Medicare Advantage, and private payer rules for CPT code 99396, especially regarding coverage and telehealth eligibility.
5. Conduct Regular Audits: Review claims to ensure compliance with AMA and payer guidelines, particularly when billing with Modifier 25 for separate E/M services.

These practices optimize revenue cycle management and improve financial outcomes for primary care practices.

Common Errors That Lead to Claim Denials

Billing errors for CPT code 99396 can lead to claim denials, delaying reimbursement. Common mistakes include:

• Incorrect Code Selection: Billing CPT code 99396 for a new patient (99386), a different age group (99395, 99397), or a problem-oriented visit (99213).
• Improper Modifier Use: Applying Modifier 25 without a separate, significant E/M service or using Modifier 95 for non-covered telehealth visits.
• Inadequate Documentation: Failing to document preventive services, such as screenings, counseling, or exam findings, to support 99396.
• Billing Medicare for Non-Covered Services: Submitting CPT code 99396 to Medicare, which typically does not cover routine physicals, instead of G0439.
• Unbundling Errors: Billing CPT code 99396 with other E/M codes without justification, violating NCCI edits.

Providers should verify codes, modifiers, and documentation to ensure accurate billing and avoid denials.
