How to Choose the Correct Pediatric Preventive CPT Code by Age

Pediatric preventive visits are routine, but choosing the correct CPT code is not always straightforward. The code depends mainly on the child’s age and whether the patient is new or established. Using the wrong age bracket can lead to claim rejections, payment delays, or unnecessary rework.

For pediatric practices, accurate preventive visit coding begins with understanding CPT 99381–99395 and applying the correct code to the date of service. This guide explains how to choose the appropriate pediatric preventive CPT code by age and avoid common billing mistakes.

Understanding Pediatric Preventive CPT Codes

Preventive medicine CPT codes are different from problem-oriented office visit codes. They are used for comprehensive preventive services such as well-child examinations, age-appropriate history and physical examination, counseling, anticipatory guidance, risk assessment, and appropriate preventive planning.

The pediatric preventive code series is divided into two main groups:

99381–99385: Initial comprehensive preventive medicine services for new patients.
99391–99395: Periodic comprehensive preventive medicine services for established patients.

Within each group, the code changes according to the patient’s age. CPT guidance identifies separate ranges for infants, early childhood, late childhood, adolescents, and adults.

The key point is simple: determine the patient’s age on the date of service, then determine whether the patient is new or established.

Pediatric Preventive CPT Codes by Age

The following age-based structure is the starting point for selecting the correct code.

Infants: Under 1 Year

For an infant younger than 1 year, use CPT 99381 for a new patient or CPT 99391 for an established patient.

These visits may include growth assessment, developmental surveillance, feeding guidance, immunization review, safety counseling, and other age-appropriate preventive services.

Early Childhood: 1–4 Years

For children from age 1 through 4 years, use CPT 99382 for a new patient or CPT 99392 for an established patient.

Preventive care commonly focuses on development, behavior, nutrition, safety, oral health, immunizations, and age-appropriate screening.

Late Childhood: 5–11 Years

For children ages 5 through 11, use CPT 99383 for a new patient or CPT 99393 for an established patient.

These visits may include growth assessment, vision or hearing screening, nutrition counseling, physical activity guidance, behavioral assessment, and immunization review.

Adolescents: 12–17 Years

For adolescents ages 12 through 17, use CPT 99384 for a new patient or CPT 99394 for an established patient.

Adolescent visits may include physical examination, mental and behavioral health screening, risk assessment, counseling, immunization review, and health education.

What Is the Difference Between New and Established Patients?

Age alone does not determine the preventive CPT code. The practice must also establish whether the patient qualifies as new or established under CPT rules.

New-patient codes are generally 99381–99385, while established-patient codes are 99391–99395. The patient’s history with the physician or same specialty within the same group practice can affect classification.

For example, a 7-year-old visiting the practice for the first qualifying professional service would generally fall under CPT 99383. A 7-year-old returning for a routine preventive visit would generally use CPT 99393.

A new insurance plan does not automatically make a patient new for CPT purposes.

Age Is Based on the Date of Service

One of the most important rules in pediatric preventive billing is to use the child’s age on the date the service is provided.

For example, if a child turns 5 before the preventive visit, the 5–11 age category applies. The practice should not use the 1–4 code simply because the child received previous visits under that category.

Billing staff should verify the date of birth and date of service, especially around birthdays.

Do Not Select Preventive Codes Based on Time or MDM

Preventive medicine codes are not selected in the same way as office visit E/M codes such as 99213 or 99214.

A common mistake is selecting a preventive code based on minutes or medical decision-making. Age and patient status drive selection.

Documentation should support the preventive history, examination, counseling, anticipatory guidance, and planning performed.

Handling Screenings and Immunizations

Screening tests, immunization products, administration services, and certain developmental or behavioral assessments may have separate CPT codes when requirements are met.

For example, CPT 96110 may apply to developmental screening when required scoring and documentation are provided. Vaccine administration follows separate rules.

Review documentation and payer rules to determine which services are separately reportable.

Preventive Visit With a Same-Day Sick Visit

A child may also present with an illness or condition requiring separate evaluation during a scheduled well-child visit.

When both preventive and problem-oriented services are performed and the requirements for separate reporting are met, the preventive medicine code and an appropriate problem-oriented E/M code may both be reported. Modifier 25 may be required on the problem-oriented E/M service when it is significant and separately identifiable.

Documentation should distinguish the preventive work from the additional problem-oriented evaluation.

Common Pediatric Preventive Coding Errors

Several mistakes occur repeatedly in pediatric billing:

Choosing a code from the wrong age bracket.
Confusing new and established patient status.
Using an office visit code instead of a preventive medicine code.
Selecting a code based on time or MDM.
Failing to document the preventive services performed.
Assuming vaccines and screenings are automatically included in every payer’s reimbursement.
Reporting a same-day sick visit without sufficient separate documentation.
Ignoring payer-specific Medicaid or commercial insurance requirements.

A careful coding review before claim submission can catch many of these problems.

How Pediatric Billing Services Can Improve Accuracy

Accurate pediatric billing also requires checking eligibility, payer policies, diagnosis coding, documentation, vaccine requirements, and claim edits.

Pediatric billing services can support practices by reviewing preventive claims, identifying coding inconsistencies, tracking denials, and helping staff follow payer requirements.

A practical workflow is to verify date of birth, patient status, the age-appropriate code, additional services, diagnosis coding, and payer rules before submission.

FAQs

What CPT codes are used for pediatric preventive visits?

Common pediatric preventive codes include 99381–99384 for new patients under age 18 and 99391–99394 for established patients under age 18. Codes 99385 and 99395 apply to patients ages 18–39.

How do I choose between 99382 and 99392?

Both codes apply to children ages 1 through 4. Use 99382 for a new patient and 99392 for an established patient.

Does age or time determine the pediatric preventive CPT code?

Age determines the preventive code within the applicable patient-status category. Time and medical decision-making are not the primary factors used to select these age-based preventive codes.

Can a well-child visit and sick visit be billed on the same day?

Yes, when both services are medically appropriate, separately identifiable, and properly documented. Modifier 25 may apply to the problem-oriented E/M service when CPT and payer requirements are met.

Are vaccines included in the preventive CPT code?

Vaccine products and administration services may be separately reportable. Practices should follow current CPT guidance and payer-specific requirements.

Conclusion

Choosing the correct pediatric preventive CPT code starts with two questions: How old is the child on the date of service, and is the patient new or established? From there, select the code from the 99381–99395 series.

Accurate documentation, review of additional services, and attention to payer requirements can reduce errors. A consistent workflow helps pediatric practices maintain cleaner claims and accurate billing.
