What Is CPT Code 99396?

CPT Code 99396 is a preventive medicine service code used for an established patient between 40 and 64 years of age.

Unlike problem oriented E/M codes, CPT 99396 focuses on preventive healthcare. The purpose of the visit is to assess the patient's overall health, identify risk factors, update medical history, perform an appropriate examination, and recommend preventive screenings or counseling.

The code represents a comprehensive preventive visit rather than treatment for a specific illness.

Patients often receive these visits annually, although coverage depends on the payer's policy.

Preventive Medicine CPT Code Family

Quick Tip: An established patient has received professional services from the physician or another physician of the same specialty within the same group practice during the previous three years, according to the CPT® Evaluation and Management guidelines.

What's Included and What Isn't

Understanding what CPT Code 99396 covers helps practices code preventive visits correctly and avoid billing errors.

Included in CPT Code 99396

A preventive visit typically includes:

• Comprehensive age appropriate medical history

• Family history review

• Social history review

• Preventive physical examination

• Vital signs assessment

• Risk factor identification

• Health risk assessment

• Counseling on healthy lifestyle choices

• Preventive screening recommendations

• Immunization review

• Personalized preventive care plan

The provider may also discuss topics such as nutrition, exercise, tobacco cessation, alcohol use, and recommended cancer screenings based on the patient's age and risk factors.

Not Included

CPT Code 99396 does not automatically include:

• Evaluation of a new medical complaint

• Management of chronic diseases

• Diagnostic procedures

• Minor surgical procedures

• Laboratory testing

• Diagnostic imaging

• Separate counseling services reported with other CPT codes when appropriate, including CPT Code 99401 when documentation supports a distinct preventive counseling service

If the provider evaluates a significant new or existing medical problem during the same visit, a separate problem oriented E/M service may be reported when documentation supports it.

Who Can Bill CPT Code 99396?

Several qualified healthcare professionals may report CPT Code 99396 when they perform and document the preventive service according to payer requirements.

Eligible providers may include:

• Family medicine physicians

• Internal medicine physicians

• General practitioners

• Nurse practitioners

• Physician assistants

• Obstetrician gynecologists

• Preventive medicine physicians

• Other qualified healthcare professionals recognized by the payer

Always verify payer specific credentialing requirements before billing preventive medicine services.

Where Can CPT Code 99396 Be Reported?

Depending on payer policy, CPT Code 99396 may be billed in settings such as:

• Physician offices

• Primary care clinics

• Community health centers

• Hospital outpatient departments

• Federally Qualified Health Centers when applicable

• Rural Health Clinics according to payer rules

The place of service should accurately reflect where the preventive visit occurred.

Does Medicare Cover CPT Code 99396?

Original Medicare generally does not reimburse preventive medicine CPT codes 99381 through 99397.

Instead, Medicare provides coverage for specific preventive wellness services using dedicated HCPCS codes.

Medicare Preventive Visit Codes

These services differ from CPT Code 99396 because they focus on preventive planning rather than a comprehensive preventive physical examination.

Medicare Advantage Plans

Medicare Advantage plans may choose to cover preventive physical examinations beyond Original Medicare benefits.

Coverage varies by plan.

Always verify patient eligibility and plan benefits before submitting a claim.

Providers offering Chronic Care Management should also verify Medicare coverage requirements for CCM services before billing preventive and chronic care services during the same period.

Important ABN Consideration

When Original Medicare excludes CPT Code 99396 because it is a statutory benefit exclusion, an Advance Beneficiary Notice (ABN) is generally voluntary rather than mandatory.

Providers should follow current CMS guidance and their organization's compliance policies when determining whether an ABN is appropriate.

Commercial Insurance and ACA Coverage

Many commercial insurance plans cover preventive services under the Affordable Care Act (ACA) when patients receive services from participating providers.

Coverage depends on several factors, including:

• Health plan benefits

• Network participation

• Patient eligibility

• Frequency limitations

• Medical necessity requirements for additional services

Some insurers allow one preventive visit per calendar year, while others apply a 365 day interval.

Understanding this distinction prevents unnecessary claim denials.

Calendar Year vs 365 Day Rule

Scheduling a preventive visit too early is a common reason for payer denials.

Practices should verify preventive visit eligibility before the appointment.

Correct ICD-10-CM Pairing for CPT Code 99396

Selecting the correct diagnosis code supports medical necessity and improves claim accuracy.

Common ICD-10-CM codes include:

Additional screening diagnosis codes may also apply depending on the preventive services performed.

Examples include:

• Z13.220 for lipid disorder screening

• Z12.11 for colorectal cancer screening

• Other screening or preventive diagnosis codes supported by the patient's clinical documentation

Providers should assign diagnosis codes that accurately reflect the services documented during the encounter.

Improper diagnosis sequencing may delay reimbursement or trigger payer edits.

For condition-specific diagnosis coding examples, see our guides on ICD-10 Code for Benign Prostatic Hyperplasia (BPH) and ICD-10 Code for UTI.

Billing CPT Code 99396 With a Problem Oriented Visit (Modifier 25)

A patient may schedule a preventive visit but also require evaluation of a separate medical condition.

In these situations, providers may report CPT Code 99396 together with an appropriate problem oriented E/M code when documentation clearly supports both services.

To report both services correctly:

• Document the preventive examination separately.

• Document the problem oriented evaluation separately.

• Show that the additional work was significant and medically necessary.

• Apply Modifier 25 to the problem oriented E/M code when payer guidelines require it.

Providers should avoid double counting the same work under both codes.

For preventive services covered under the Affordable Care Act, incorrect use of Modifier 25 may affect the patient's cost sharing responsibility. Practices should understand payer specific billing policies before reporting both services.

Another modifier that may apply in preventive care is Modifier 33, which identifies eligible preventive services when required by the payer.

Why CPT Code 99396 Claims Get Denied

Even when providers document preventive visits correctly, claims may still face rejection or denial. Most denials result from avoidable billing mistakes, incorrect coding, or payer policy violations.

Understanding the cause helps billing team correct issues quickly and improve first-pass claim acceptance.

The exact CARC and RARC codes vary by payer. Always review the payer's remittance advice and claim policy before appealing a denial.

Common Denial Prevention Tips

Reduce denials by following these best practices:

• Verify insurance eligibility before the visit.

• Confirm preventive benefit frequency.

• Select the correct patient status.

• Pair CPT and ICD-10-CM codes accurately.

• Review documentation before claim submission.

• Use claim scrubbing tools to identify errors.

• Monitor payer edits regularly.

• Appeal incorrect denials with supporting documentation.

A structured denial management process improves reimbursement and reduces administrative work.

What Does CPT Code 99396 Cost?

There is no standard national price for CPT Code 99396.

The amount paid depends on several factors, including:

• Insurance payer

• Geographic location

• Provider contract

• Place of service

• Medicare locality

• Commercial fee schedules

Avoid relying on estimated reimbursement figures from blogs or unofficial sources.

Instead, verify payment using trusted resources such as:

• Medicare Physician Fee Schedule

• Commercial payer fee schedules

• FAIR Health Consumer cost estimator

• Your organization's contracted reimbursement rates

Checking official payment sources provides more accurate reimbursement expectations than generalized price ranges.

Can CPT Code 99396 Be Billed Through Telehealth?

In most situations, CPT Code 99396 is not routinely reported for telehealth because the code describes a comprehensive preventive medicine service that generally includes an in-person physical examination.

However, telehealth coverage continues to evolve.

Some commercial insurance plans may reimburse preventive counseling delivered through telehealth, while others require an in-person visit.

Before billing telehealth services, practices should verify:

• Current payer policy

• Federal and state regulations

• Place of service requirements

• Telehealth modifier requirements

• Documentation standards

Never assume all preventive visits qualify for telehealth reimbursement.

Always confirm coverage before claim submission.

These services are not interchangeable.

CPT 99396 vs CPT 99401 to 99404

Preventive medicine codes and preventive counseling codes serve different purposes.

Providers should report the code that best matches the documented service. When coding similar preventive services, accurate medical coding helps ensure proper code selection and reduces billing errors.

Documentation Requirements

Complete documentation supports accurate coding and reduces audit risk.

Every preventive visit should include:

✔ Chief purpose of preventive visit

✔ Comprehensive medical history

✔ Family history

✔ Social history

✔ Medication review

✔ Allergy review

✔ Preventive physical examination

✔ Risk factor assessment

✔ Counseling provided

✔ Recommended screenings

✔ Immunization review

✔ Follow-up recommendations

✔ Provider signature

If a separate problem-oriented E/M service is reported, document it independently to support accurate coding and reimbursement.

Add-On Screening Codes Commonly Reported With CPT 99396

Depending on the patient's condition and payer policy, providers may report additional screening services during the preventive visit.

Common examples include:

These services require separate documentation and must satisfy payer billing requirements.

Medical necessity and documentation remain essential for reimbursement.

Compliance and Audit Risks

Preventive medicine services receive regular attention during payer audits.

Common compliance risks include:

• Reporting the wrong age-based CPT code

• Incorrect patient status

• Insufficient documentation

• Upcoding preventive visits

• Billing problem-oriented services without separate documentation

• Improper Modifier 25 use

• Duplicate billing

• Missing preventive diagnosis codes

Regular coding audits help practices identify billing trends before they affect revenue.

Compliance reviews also improve documentation quality and reduce future denials.

A Denial Prevention Workflow

Practices can reduce preventable denials by following a consistent workflow.

1. Verify patient insurance eligibility.

2. Confirm preventive visit benefits and frequency.

3. Review patient history before the appointment.

4. Document the preventive service completely.

5. Assign accurate CPT and ICD-10-CM codes.

6. Apply modifiers only when supported.

7. Use claim scrubbing software before submission.

8. Monitor claim status after submission.

9. Respond quickly to payer requests.

10. Appeal incorrect denials with supporting documentation.

This workflow improves claim accuracy and strengthens revenue cycle performance.
