CPT code 99381: Infant preventive visit, new patient, under 1 year2026 Medicare rate & RVUs

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

What 99381 covers

99381 reports a comprehensive preventive evaluation and management visit for a new infant patient younger than 1 year. The clinician obtains an age-appropriate health history, performs a preventive examination, and provides counseling or anticipatory guidance to the caregiver. Pediatricians and other clinicians provide this service in settings such as an office or clinic as part of routine well-child care.

CMS physician fee schedule status N identifies 99381 as not covered by Medicare. Select it for a new-patient preventive service in the infant age band; an established infant uses 99391, while a new patient aged 1 through 4 years uses 99382. This code identifies a preventive encounter, not a problem-focused visit for an acute illness.
