CPT code 99391: Infant preventive visit, established patient2026 Medicare rate & RVUs in Florida

CMS doesn’t publish an office rate for 99391 in Florida.

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

What 99391 covers

This code describes a routine preventive evaluation for an infant younger than one year who is an established patient. A pediatrician, family physician, or other qualified clinician typically provides the visit in an office or clinic. The service centers on age- and sex-appropriate history and examination, preventive counseling, anticipatory guidance, and risk-reduction discussions, rather than evaluation of a specific illness alone. An infant seen for a separate acute concern may also receive problem-oriented evaluation when that work is distinct from the preventive service.

Medicare classifies this CPT code as status N, meaning Medicare does not cover it. The code represents one preventive visit, not a timed service or a drug or supply unit. Use the established-patient age range to distinguish it from the infant preventive code for a new patient and from preventive visits for older children. For CPT purposes, an established patient has received professional services within the previous three years from the same physician or qualified health professional, or another physician or qualified health professional of the same specialty and subspecialty in the same group.
