CPT® Code 99386

Quick Reference: CPT 99386

• Definition: CPT 99386 represents an initial comprehensive preventive medicine E/M service for a new patient age 40-64. It includes an age- and gender-appropriate history, examination, counseling/anticipatory guidance, risk factor reduction interventions, and ordering of appropriate screening tests.
• Not payable by Original Medicare: Medicare generally does not cover CPT 99381-99397. For Medicare-covered preventive visits, use the Medicare wellness benefit codes (e.g., G0402 IPPE, G0438 initial AWV, G0439 subsequent AWV). If a Medicare patient requests a "routine physical," practices commonly provide written notice (often an ABN-style notice) that Medicare will deny routine physicals as non-covered.
• Preventive vs problem-oriented work: If a significant new or existing problem is evaluated/managed beyond routine preventive counseling, you may bill a separate office/outpatient E/M (99202-99215) with modifier -25 on the problem E/M, alongside 99386.
• Modifier 33: For commercial plans, modifier 33 helps designate certain services as preventive for cost-sharing waiver under ACA rules, but it is generally not required on an inherently preventive E/M like 99386. Medicare does not rely on modifier 33 for its preventive benefit structure.
• Billing reality: Many commercial plans cover one adult preventive visit per year under preventive benefits (frequency rules vary by plan). Medicare Advantage plan behavior can differ and often follows plan-specific preventive guidance documents.

CPT 99386 is the standard code used by most non-Medicare payers for a new patient's "annual physical" in the 40-64 age range. The service is designed for prevention and health maintenance: risk assessment, screening planning, immunization review, and counseling. Its "comprehensive" nature is preventive breadth, not a point-counted organ system checklist. When documentation, diagnosis selection, and modifier use align with that preventive intent, 99386 typically adjudicates as a preventive benefit for commercial plans.

The most common billing problems with 99386 arise from coverage mismatch (billing it to Original Medicare) and mixed-visit confusion (combining preventive and problem-oriented work without clean separation and modifier -25). This guide shows how to structure the encounter and the claim so payers can adjudicate the preventive portion correctly, while still paying for legitimate additional evaluation/management when it occurs.

1. Definition and Clinical Use Criteria

CPT 99386 is defined as an initial comprehensive preventive medicine evaluation and management service for a new patient age 40-64, including age/gender-appropriate history and exam, counseling/anticipatory guidance/risk factor reduction, and the ordering of labs/diagnostic procedures. "New patient" generally means the person has not received face-to-face professional services from the physician (or another physician of the same specialty within the same group) in the past three years, which is the common E/M framework used by payers and coding education.

When 99386 is the correct choice

Use 99386 when the primary purpose of the visit is prevention: reviewing health status, updating personal and family history, identifying modifiable risk factors, and establishing a preventive plan (screenings, immunizations, and counseling). In typical outpatient workflows, 99386 applies when:

• The patient is new to the practice and is 40-64.
• The encounter is framed as a preventive visit (annual physical/wellness exam for commercial payers).
• The clinician performs and documents the required elements (history, exam, counseling/risk reduction, ordering of screenings).

Preventive services guidance from national physician organizations and payer policies emphasize that preventive medicine services incorporate counseling, risk-factor evaluation, and the ordering of appropriate screening tests as part of the preventive E/M. Practically, this means you do not need a chief complaint for 99386; instead, you should document the preventive intent and the patient's preventive needs.

When 99386 is not the best code

If the visit is primarily problem-oriented (evaluation of symptoms, management of an acute condition, or intensive chronic disease management) and the preventive elements are not performed comprehensively, a problem-oriented office/outpatient E/M is typically more appropriate. Conversely, if both preventive care and significant problem-oriented work occur, 99386 can remain appropriate -- but only if the record supports a genuine preventive service and a separately identifiable problem service (with correct modifier use and diagnosis separation).

Operational rule: Code selection should reflect what actually happened. If the record does not show a comprehensive preventive service, billing 99386 can create audit vulnerability. If the record clearly supports prevention plus a significant separate problem evaluation, structured documentation and modifier -25 are the usual pathway to legitimate combined billing.

2. Documentation Requirements (History, Exam, Counseling)

Documentation for 99386 should read like a comprehensive mid-life preventive evaluation: risk assessment plus a plan for preventive services. While preventive codes are not selected by time or by the older bullet-style exam scoring, payers still expect the record to demonstrate each required preventive component. Payer preventive policies describe these services as including age- and gender-appropriate history and examination, counseling and risk reduction, and ordering of immunizations and screening tests.

Comprehensive preventive history (40-64)

For adults 40-64, a defensible preventive history typically includes:

• Interval health review: major illnesses, surgeries, hospitalizations, current conditions and stability, medications and supplements, allergies.
• Family history update: premature cardiovascular disease, diabetes, cancers (breast/colon/prostate), and other hereditary risks.
• Social history and risk factors: tobacco exposure, alcohol use, exercise and diet patterns, occupational exposures, sexual health risks, sleep, stress, and safety factors.
• Preventive history: immunization status; prior screening dates/results (colon screening status, cervical screening history, mammography history when applicable).

The goal is not to create maximum length, but to show that preventive risk factors were assessed and that counseling and screening decisions were made based on those risks -- consistent with how preventive care services are described in payer and professional guidance.

Comprehensive preventive exam (age/gender appropriate)

The physical exam should be a head-to-toe preventive exam tailored to age and gender. Typical elements include:

• Vitals and measurements: BP, weight/BMI, and other routine measurements as appropriate.
• General exam: heart, lungs, abdomen, skin, neurologic screening, and musculoskeletal observation as clinically appropriate.
• Gender-specific content when indicated: breast and pelvic exam in women when clinically due/appropriate; male genital exam when appropriate; prostate-related discussion and exam decisions based on patient context and guidelines.

A practical way to make documentation audit-resilient is to connect exam elements to prevention: for example, documenting counseling and ordering decisions tied to measured BP/BMI, family history, or lifestyle risk factors. Medicare's preventive framework for AWV and other preventive services illustrates how payers operationalize required elements and checklists, even though 99386 itself is not a Medicare benefit.

Counseling, anticipatory guidance, and risk reduction

Counseling is an explicit component of 99386. For 40-64, counseling often includes:

• Cardiometabolic prevention: nutrition, physical activity, weight, BP awareness, and lipid/diabetes screening planning as appropriate.
• Cancer prevention and screening schedule: colorectal screening timelines; cervical screening planning; breast screening planning.
• Substance use: smoking cessation counseling and alcohol risk discussion when relevant.
• Immunizations: review and recommendations consistent with age and risk status.
• Safety and mental health: depression/stress screening approach when indicated; injury prevention counseling as appropriate.

Document counseling in specific, actionable terms (what was discussed and what the plan is). Payer preventive care policies commonly describe preventive services as including counseling, risk factor reduction interventions, and the ordering of appropriate immunizations and screening tests.

Ordering screenings and preventive tests (what is included vs separately billable)

The ordering of tests is part of the preventive E/M, but the tests themselves (lab processing, imaging, procedures, vaccine products/administration) are billed separately when performed. The preventive E/M is the clinician's evaluation, counseling, and plan. For Medicare beneficiaries, CMS publishes preventive service references that outline what Medicare covers and under what billing codes, which helps practices avoid charging Medicare for excluded "routine physical" services.

3. Medicare and Commercial Payer Coverage Guidelines

Commercial insurance and ACA preventive benefits

Most commercial plans cover adult preventive visits at no cost-sharing when delivered within plan rules and when coded as preventive. Payer policies often define preventive visits as including age/gender-appropriate history and exam, counseling and risk reduction, and ordering of screening tests. Frequency and eligibility rules vary (calendar-year vs 12-month intervals), and plans may deny "duplicate" preventive visits if the patient already had a covered preventive exam within the plan's permitted timeframe.

In practice, the coding levers that most affect commercial adjudication are:

• Diagnosis selection: use a preventive Z code as primary for the preventive service so it adjudicates under preventive benefits.
• Separation of problem work: when billing both preventive and problem E/M, link the problem diagnosis to the problem E/M and keep the preventive diagnosis linked to 99386.
• Modifier logic: apply modifier -25 only to the problem-oriented E/M when a significant separate problem service occurred.

Original Medicare: why 99386 is not covered

Traditional Medicare does not generally pay CPT preventive medicine codes 99381-99397. CMS has explicitly instructed providers not to bill those codes for Medicare-covered preventive services that should be reported with Medicare-specific HCPCS codes such as G0402, G0438, and G0439. Medicare's preventive benefit structure relies on a defined wellness visit model (AWV) plus separate preventive screenings, rather than a single comprehensive routine physical code.

Billing consequence: If you submit 99386 to Original Medicare, it is typically processed as non-covered. If a Medicare patient wants a "full physical" beyond covered wellness elements, practices commonly provide clear written notice that the service is not covered and may be billed to the patient.

Medicare Advantage: plan-specific preventive guidance

Medicare Advantage (MA) plans cover Medicare-required benefits (AWV) and may also offer supplemental preventive benefits that resemble commercial coverage. Some MA organizations publish preventive services coding guidelines that specify how to report AWVs and preventive screenings. If a plan offers an additional "routine physical" benefit, it may accept preventive CPT codes -- yet coverage rules and same-day billing policies can be plan-specific. Always follow the plan's published guidance and eligibility rules for the beneficiary.

CMS preventive services references (useful in daily operations)

CMS provides a preventive services quick reference that outlines covered Medicare preventive benefits and intervals, which helps offices schedule AWVs and screenings correctly and avoid billing excluded routine physical codes to Medicare. Even when your patient population is mostly commercial, this reference is often used operationally for beneficiaries who transition into Medicare during the 40-64 to 65+ boundary.

4. Modifier Use (25, 33, and common pitfalls)

Modifier -25: preventive + problem visit on the same date

Modifier -25 is the central modifier when 99386 is paired with a problem-oriented office/outpatient E/M on the same date. The core requirement is that the problem-oriented E/M must be significant and separately identifiable from the preventive service. Professional guidance explains that when a wellness/preventive encounter also includes distinct problem evaluation/management, both codes may be reported if documentation clearly supports the separate work and modifier -25 is placed on the problem E/M.

A strong documentation pattern is to separate the note into:

• Preventive section: preventive history, preventive exam, counseling, screening and immunization plan.
• Problem section: HPI/exam/assessment-plan for the specific complaint or chronic condition management changes.

This structure makes it easier for payer reviewers to see that the preventive E/M would stand alone as a complete preventive service, and that the problem work would also stand alone as a medically necessary E/M visit.

Modifier 33: preventive designation for commercial plans

Modifier 33 is primarily a commercial payer tool for signaling that a service was preventive under ACA-related cost-sharing rules. The AMA's preventive services coding guidance describes how preventive intent can affect cost-sharing and modifier application for services that may otherwise adjudicate as diagnostic. For a code that is inherently preventive by definition (such as a preventive medicine E/M), many payers do not require modifier 33 on the preventive E/M itself. Where modifier 33 can matter more is on other services (screening procedures, counseling services, or certain preventive interventions) that might otherwise process as diagnostic depending on context.

Medicare and modifier 33

Medicare's preventive benefits operate through Medicare-specific codes and statutory preventive coverage rules rather than reliance on modifier 33. CMS billing instructions focus on using the correct Medicare HCPCS preventive codes (e.g., G0438/G0439) and not billing CPT preventive medicine codes to Original Medicare.

5. Comparison Table: 99385 vs 99386 vs 99387 vs G0438

CMS billing instructions emphasize that Medicare beneficiaries should not be billed using 99381-99397 for Medicare-covered preventive benefits, and that offices should use the appropriate Medicare preventive HCPCS codes instead. MA plans may publish their own preventive coding guidelines; providers should follow the plan's published policy documents.

6. Real-World Clinical Scenarios

Scenario 1: New patient preventive exam (no significant problems)

Patient: 50-year-old new patient requests an "annual physical," no acute complaints.

Service: Comprehensive preventive history and exam, counseling on diet/exercise, review of immunizations, screening plan (e.g., colorectal screening discussion and ordering as indicated).

Coding approach: Bill 99386 as the preventive E/M with an appropriate preventive diagnosis. Document counseling and screening orders as part of preventive service elements described in preventive policies.

Scenario 2: Preventive exam plus distinct acute symptom evaluation (modifier -25)

Patient: 46-year-old new patient scheduled for preventive exam but reports new exertional chest tightness.

Service: Preventive exam performed, plus a separately identifiable evaluation of the chest symptom (focused HPI, targeted exam, and appropriate diagnostic/management decisions).

Coding approach: Bill 99386 for the preventive service and bill a problem-oriented E/M with modifier -25 on the problem E/M, with separate diagnosis linkage, consistent with guidance on combining wellness and problem-oriented visits.

Scenario 3: Preventive exam plus active chronic disease management (med changes)

Patient: 59-year-old new patient with diabetes and hypertension requests a physical and needs medication adjustment.

Service: Full preventive service plus substantive chronic disease management (e.g., medication changes, additional workup plans).

Coding approach: Preventive E/M plus separately identifiable problem E/M with -25 if documentation supports the distinct management work; ensure the record clearly differentiates preventive counseling from chronic management decision-making.

Scenario 4: Medicare beneficiary requesting an "annual physical"

Patient: 70-year-old on Original Medicare schedules a "physical."

Operational guidance: Explain Medicare's preventive benefits (IPPE/AWV) and that routine physical exams (CPT 99381-99397) are generally non-covered by Original Medicare. Use the Medicare wellness visit code if providing an eligible AWV, and provide clear written notice if the patient requests a non-covered routine physical component.

Scenario 5: Plan frequency issue (recent preventive exam elsewhere)

Patient: 42-year-old new patient had a covered preventive exam 6 months ago with another clinician and now requests another "annual physical."

Risk: Many commercial plans limit adult preventive exams by calendar year or a 12-month interval, so the new claim may deny as frequency exceeded.

Practical approach: Confirm preventive eligibility and, if not eligible, shift the visit toward problem-oriented needs (if present) or schedule the preventive exam when plan eligibility returns. Payer preventive policies often describe frequency limits and coverage as plan-dependent.

Scenario 6: Preventive exam plus separate preventive-designation issue (modifier 33 on non-E/M services)

Patient: 55-year-old new patient receives a preventive exam and also receives a separate preventive screening service that can adjudicate as diagnostic depending on coding context.

Approach: Keep 99386 as preventive. Consider modifier 33 on the separate service when payer guidance indicates it helps identify the service as preventive for cost-sharing purposes. The AMA preventive coding guidance discusses preventive designation considerations for services beyond the preventive E/M itself.

Across scenarios, the consistent strategy is: (1) ensure the preventive service is complete and clearly documented, (2) separate problem-oriented work when it rises to a significant and separately identifiable service, (3) apply modifier -25 to the problem E/M when appropriate, and (4) follow Medicare-specific rules when the patient is a Medicare beneficiary to avoid routine-physical denials.
