CPT code 99384: Adolescent preventive visit, new patient, ages 12–172026 Medicare rate & RVUs in Missouri

CMS doesn’t publish an office rate for 99384 in Missouri.

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 99384 covers

Code 99384 identifies an initial comprehensive preventive medicine evaluation for a new patient aged 12 through 17. A physician or other qualified clinician typically provides the service in an office or clinic. The encounter focuses on preventive health rather than assessment of a specific illness or injury, with age-appropriate history and examination, counseling, anticipatory guidance, and risk-factor reduction. The age band distinguishes it from preventive visits for younger or older patients.

Medicare classifies 99384 as not covered, status N. It is a CPT Category I code for a new adolescent preventive visit; the established-patient counterpart for ages 12 through 17 is 99394. Select the code according to both patient status and age range, rather than using it for an established patient or a patient outside this age band.
