Try CasePilotCPT code 99401 is defined as “Preventive medicine counseling and/or risk factor reduction intervention(s) provided to an individual (separate procedure); approximately 15 minutes.”
In simple terms, this code represents a one-on-one counseling session focused on promoting health and preventing illness rather than treating a current medical condition. In the 2025 coding landscape, mastering this code is essential for primary care, pediatrics, and behavioral health providers looking to capture revenue for risk reduction discussions.
This comprehensive guide covers everything you need to know about CPT 99401, including time requirements, the “midpoint rule,” payer differences (Medicare vs. Commercial), and proper modifier usage.
CPT 99401 is used for preventive counseling aimed at reducing risk factors and encouraging healthy behaviors. Importantly, this code is intended for patients who do not have symptoms or an established illness related to the counseling topic.
If the counseling is related to a current medical problem (e.g., diet counseling as part of diabetes management), 99401 should not be billed; that counseling is considered part of the problem-focused E/M service (99213/99214).
CPT 99401 is strictly a time-based code. To bill it, you must meet specific duration thresholds based on the CPT “midpoint rule.” This rule states that you must pass the midpoint of the stated time to bill the code.
| CPT Code | Stated Duration | Required Face-to-Face Time |
|---|---|---|
| 99401 | Approx. 15 minutes | 8 – 22 minutes |
| 99402 | Approx. 30 minutes | 23 – 37 minutes |
| 99403 | Approx. 45 minutes | 38 – 52 minutes |
| 99404 | Approx. 60 minutes | 53 minutes or more |
Compliance Alert: Do not bill multiple units of 99401 for a longer session. If the counseling lasts 30 minutes, report 99402 once, rather than 99401 x 2. Only one unit is allowed per patient per day.
Accurate documentation is your defense against audits. Because time is the controlling factor, your notes must clearly reflect the duration and content. Include the following elements:
Diagnosis Coding: Use preventive ICD-10 codes (Z-codes) to support 99401. Common examples include:
CPT 99401 is a “separate procedure,” but it is frequently billed alongside other services. Correct modifier usage is critical for payment.
If you provide a significant, separately identifiable counseling session on the same day as a problem-focused visit (e.g., 99213), you can bill both.
Generally Not Recommended. Most preventive exam codes (99381–99397) include age-appropriate counseling as part of the service. Billing 99401 alongside an annual physical often leads to denials or bundling.
In 2025, many payers continue to cover 99401 via telehealth. Ensure you use the correct modifier based on payer policy:
Coverage for 99401 varies drastically depending on the insurance type. This is the most common source of confusion for billing teams.
| Payer Type | Coverage Status | What to Use Instead |
|---|---|---|
| Medicare (Part B) | Non-Covered. Medicare statutorily excludes “routine preventive medicine counseling.” | Use G-codes (G0447 for obesity, G0443 for alcohol) or CPT 99406/99407 for tobacco. Use Annual Wellness Visits (G0438/G0439). |
| Commercial (Private) | Generally Covered. ACA mandates coverage for USPSTF A/B rated services (diet, tobacco, etc.). | Use 99401–99404 with appropriate Z-codes (e.g., Z71.3). Often paid at 100% (no copay). |
| Medicaid | Varies by State. Many follow Medicare rules (non-covered), while others cover it for specific programs. | Check your state fee schedule. Some states use T-codes or S-codes for health education. |

A 52-year-old with a family history of heart disease (but no personal diagnosis) visits for advice on heart-healthy eating. The physician spends 20 minutes discussing low-sodium diets.
Billing: 99401 linked to Z71.3 (Dietary counseling).
A patient visits for asthma follow-up. The doctor spends 15 minutes managing meds for wheezing. The patient also smokes, so the doctor spends an additional 10 minutes counseling on cessation strategies.
Billing: 99213-25 (Asthma) + 99401 (Tobacco).
A Medicare patient requests diet advice for weight loss. The doctor spends 15 minutes counseling.
Result: Billing 99401 will result in a denial (Non-Covered Service). The provider should instead use HCPCS G0447 if the patient meets BMI criteria >30, or bill the patient privately if an ABN is signed.
Generally, No. Medicare Part B does not cover CPT 99401. Medicare pays for specific preventive counseling using G-codes (e.g., G0447 for obesity) or 99406/99407 for tobacco cessation.
No. If you are billing 99401 alongside a problem-oriented visit (e.g., 99213), the Modifier 25 goes on the 99213, not the 99401.
Per the CPT midpoint rule, 99401 requires a minimum of 8 minutes of face-to-face counseling time (up to 22 minutes).
No. CPT 99401 is for individual counseling only. For group sessions, you should use CPT codes 99411 or 99412.

| 25 | Significant, separately identifiable evaluation and management service by the same physician or other qualified health care professional on the same day of the procedure or other service: it may be necessary to indicate that on the day a procedure or service identified by a cpt code was performed, the patient's condition required a significant, separately identifiable e/m service above and beyond the other service provided or beyond the usual preoperative and postoperative care associated with the procedure that was performed. a significant, separately identifiable e/m service is defined or substantiated by documentation that satisfies the relevant criteria for the respective e/m service to be reported (see evaluation and management services guidelines for instructions on determining level of e/m service). the e/m service may be prompted by the symptom or condition for which the procedure and/or service was provided. as such, different diagnoses are not required for reporting of the e/m services on the same date. this circumstance may be reported by adding modifier 25 to the appropriate level of e/m service. note: this modifier is not used to report an e/m service that resulted in a decision to perform surgery. see modifier 57 for significant, separately identifiable non-e/m services, see modifier 59. | GA | Waiver of liability statement issued as required by payer policy, individual case | GY | Item or service statutorily excluded, does not meet the definition of any medicare benefit or, for non-medicare insurers, is not a contract benefit | 95 | Synchronous telemedicine service rendered via a real-time interactive audio and video telecommunications system: synchronous telemedicine service is defined as a real-time interaction between a physician or other qualified health care professional and a patient who is located at a distant site from the physician or other qualified health care professional. the totality of the communication of information exchanged between the physician or other qualified health care professional and the patient during the course of the synchronous telemedicine service must be of an amount and nature that would be sufficient to meet the key components and/or requirements of the same service when rendered via a face-to-face interaction. modifier 95 may only be appended to the services listed in appendix p. appendix p is the list of cpt codes for services that are typically performed face-to-face, but may be rendered via a real-time (synchronous) interactive audio and video telecommunications system. | 59 | Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25. | 33 | Preventive services: when the primary purpose of the service is the delivery of an evidence based service in accordance with a us preventive services task force a or b rating in effect and other preventive services identified in preventive services mandates (legislative or regulatory), the service may be identified by adding 33 to the procedure. for separately reported services specifically identified as preventive, the modifier should not be used. | CR | Catastrophe/disaster related | SA | Nurse practitioner rendering service in collaboration with a physician | FQ | The service was furnished using audio-only communication technology | AQ | Physician providing a service in an unlisted health professional shortage area (hpsa) | XU | Unusual non-overlapping service, the use of a service that is distinct because it does not overlap usual components of the main service | GX | Notice of liability issued, voluntary under payer policy | X1 | Continuous/broad services: for reporting services by clinicians, who provide the principal care for a patient, with no planned endpoint of the relationship; services in this category represent comprehensive care, dealing with the entire scope of patient problems, either directly or in a care coordination role; reporting clinician service examples include, but are not limited to: primary care, and clinicians providing comprehensive care to patients in addition to specialty care | GZ | Item or service expected to be denied as not reasonable and necessary | 51 | Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d). | FP | Service provided as part of family planning program | GC | This service has been performed in part by a resident under the direction of a teaching physician | HM | Less than bachelor degree level | 24 | Unrelated evaluation and management service by the same physician or other qualified health care professional during a postoperative period: the physician or other qualified health care professional may need to indicate that an evaluation and management service was performed during a postoperative period for a reason(s) unrelated to the original procedure. this circumstance may be reported by adding modifier 24 to the appropriate level of e/m service. | 52 | Reduced services: under certain circumstances a service or procedure is partially reduced or eliminated at the discretion of the physician or other qualified health care professional. under these circumstances the service provided can be identified by its usual procedure number and the addition of modifier 52, signifying that the service is reduced. this provides a means of reporting reduced services without disturbing the identification of the basic service. note: for hospital outpatient reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well-being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for asc hospital outpatient use). | 93 | Synchronous telemedicine service rendered via telephone or other real-time interactive audio-only telecommunications system : synchronous telemedicine service is defined as a real-time interaction between a physician or other qualified health care professional and a patient who is located away at a distant site from the physician or other qualified health care professional. the totality of the communication of information exchanged between the physician or other qualified health care professional and the patient during the course of the synchronous telemedicine service must be of an amount and nature that is sufficient to meet the key components and/or requirements of the same service when rendered via a face-to-face interaction. | AF | Specialty physician | AM | Physician, team member service | AT | Acute treatment (this modifier should be used when reporting service 98940, 98941, 98942) | CC | Procedure code change (use 'cc' when the procedure code submitted was changed either for administrative reasons or because an incorrect code was filed) | CS | Cost-sharing waived for specified covid-19
