CPT code 99383: Preventive medicine visit for new patients ages 5-11

Key Takeaways

CPT code 99383 is the initial comprehensive preventive medicine E/M code for new patients aged 5 through 11 years.

Visits are coded by patient age and new/established status, not by medical complexity or time spent.

The established patient equivalent is CPT 99393; billing the wrong new/established status is a top denial trigger.

Pabau’s claims management software automates charge capture and flags keying errors before claims reach the payer.

CPT code 99383 reports the initial comprehensive preventive medicine visit for a new patient aged 5 through 11 years. Primary care EHR software with built-in preventive code mapping helps route the visit to the correct code automatically, but coders still need to know when 99383 applies, what the visit must include, and how to document it correctly.

This reference guide covers the code definition, age eligibility, documentation requirements, reimbursement data, related preventive medicine codes, and the most common billing errors – everything pediatric practices and primary care billing teams need to submit clean claims for well-child visits in the 5-11 age range.

CPT code 99383: Definition and age eligibility

CPT code 99383 describes an initial comprehensive preventive medicine evaluation and management service for a new patient aged 5 through 11 years. The American Medical Association (AMA) classifies it under the Preventive Medicine Services section of the CPT code set, which covers age- and gender-appropriate evaluations rather than the problem-oriented E/M codes used for sick visits.

Three criteria define whether 99383 is the right code to report:

• New patient status: The patient has not received professional services from the physician, or another physician of the same specialty in the same group practice, within the past three years.
• Age at time of visit: The patient is 5 years old through 11 years old on the date of service. A child turning 12 before the visit is reported under CPT 99384 instead.
• Preventive intent: The visit is a well-child or health maintenance encounter, not a sick visit or problem-focused evaluation.

According to the Society of Teachers of Family Medicine (STFM) Practice Management Handbook, preventive care visits are coded based on the patient’s age and the services provided, not on medical complexity or time. This is a fundamental difference from problem-oriented E/M codes where medical decision-making and time drive code selection.

What a CPT code 99383 visit must include

The AMA descriptor for CPT code 99383 requires all of the following components to be present and documented. Missing any one element creates grounds for a payer audit or claim downcoding.

The NCBI Bookshelf confirms that codes 99383-99397 include counseling, anticipatory guidance, and risk factor reduction interventions provided at the time of the comprehensive preventive examination. These services are bundled into the preventive visit code – they are not separately billable on the same date unless a significant separately identifiable problem-oriented E/M service is also provided.

Nutrition counseling folded into the preventive visit is included in 99383’s payment. A distinct, separately scheduled medical nutrition therapy session (CPT 97804) is billed on its own and is not part of this bundle.

The American Academy of Pediatrics (AAP) Bright Futures guidelines provide the periodicity schedule that most payers use to determine coverage frequency. Aligning documentation with Bright Futures recommendations strengthens medical necessity for the visit and supports coverage under most commercial plans. Using digital intake forms that capture Bright Futures-aligned history elements at check-in gives the provider a complete history before they enter the room.

Documentation requirements for CPT code 99383

Payers reviewing 99383 claims look for documentation that demonstrates a comprehensive preventive visit occurred. Sparse or templated notes are the fastest path to a medical record request or post-payment audit.

History and physical

The note must record the child’s age, weight, height, BMI percentile, blood pressure, and head circumference (if applicable). A complete review of systems relevant to school-age children – including behavioral, developmental, and academic concerns – should be present. Generic templates that auto-populate identical notes across patients are a red flag during audits.

Anticipatory guidance documentation

Each topic discussed must be individually noted. Acceptable documentation includes the specific subjects covered (screen time limits, helmet use, sun protection, healthy eating) and whether written materials were provided, such as an internet addiction screening template for families with device-use concerns.

A single line reading “anticipatory guidance provided” is insufficient for most payers. The HIPAA compliance checklist for primary care reinforces that documentation must reflect the encounter itself, not a template-generated summary.

Immunization and screening records

Vaccines administered at the visit are billed separately using the appropriate vaccine product and administration codes, such as CPT 90715 for the Tdap vaccine. The preventive visit note should document the immunization review (which vaccines are current, which are due, any refusals) and any screenings completed or ordered. Digital medical forms with built-in immunization checklists streamline this capture at the point of care.

Developmental and behavioral assessment

For the 5-11 age group, documentation should reflect a structured developmental and behavioral assessment. Validated screening tools (such as the Pediatric Symptom Checklist) may be used. Any concerns identified must be linked to a plan – referral, watchful waiting, or follow-up appointment – to demonstrate medical necessity and complete the clinical picture.

CPT code 99383 reimbursement and RVU data

Reimbursement for CPT code 99383 varies by payer, locality, and plan year. The figures below reflect publicly available data; always verify current rates against the applicable fee schedule before relying on specific dollar amounts.

Use the CMS Physician Fee Schedule lookup to retrieve the current non-facility and facility payment amounts for your locality. The FastRVU 2026 RVU lookup tool provides Work, Practice Expense, and Malpractice RVU values alongside the geographic cost practice index (GPCI) multipliers that affect the final Medicare allowable.

For practices using claims management software, mapping preventive visit codes to the correct fee schedule in the charge master reduces the frequency of manual rate corrections and keeps expected reimbursement figures current across payers.

Reduce preventive visit claim denials

Pabau's claims management software maps CPT codes to the correct fee schedules, flags eligibility issues before submission, and tracks denial patterns by code so your billing team spends less time on rework.

Related preventive medicine CPT codes: The full age-based series

CPT code 99383 sits within a structured series of preventive medicine codes organized by patient age and new/established status. Knowing the full series prevents age-boundary errors that trigger denials when a child’s age changes between visits.

New patient preventive medicine codes (99381-99387)

Established patient preventive medicine codes (99391-99397)

The established patient equivalent for the 5-11 age range is CPT 99393. Practices transitioning children from another practice typically bill 99383 correctly on the first visit, then shift to 99393 for all subsequent annual well-child visits.

Misidentifying an established patient as new, or the reverse, is one of the most common preventive visit denials. The full age-based series for both new and established patients appears in the tables above.

CPT 99383 vs. 99393: Key differences

The clinical content of the visit is identical – both cover ages 5-11 with the same comprehensive components. The only difference is patient status at time of service.

• CPT 99383: New patient. Use when the child has not received any professional services from the physician or same-specialty group within the past three years. Typical scenario: a child transferring from another practice, a new patient to the area, or a family switching insurance that requires establishing care with a new provider.
• CPT 99393: Established patient. Use for all subsequent annual well-child visits once the initial new-patient visit has been billed. Same age range (5-11), same documentation requirements, different code.

Payers match the new/established status designation against their enrollment files. If a child has prior claims on file with the same practice under a previous insurance plan, billing 99383 instead of 99393 will often result in a denial or a payer-initiated audit. Consistent patient status tracking in patient care management workflows prevents this error at the scheduling stage.

School physicals and CPT code 99383

There is no separate CPT code for a school physical. When a parent brings a child aged 5-11 in specifically for a school or sports clearance form, the correct code is still CPT 99383 (new patient) or CPT 99393 (established patient) – provided the visit meets the comprehensive preventive visit requirements.

The visit must be documented as a full well-child encounter rather than a form completion alone. If the physician only fills out a school form without conducting the comprehensive examination, history, and anticipatory guidance components, the visit does not meet the requirements for either 99383 or 99393. In that case, a problem-oriented or administrative service code may be more appropriate depending on the payer’s policies.

Many payers will not reimburse for school physicals that lack the full preventive documentation, regardless of how the visit is coded. Documenting the complete encounter protects the practice if the claim is reviewed.

Common billing errors and denial reasons for CPT code 99383

Most 99383 denials trace back to a small set of repeating errors. Catching them at the point of coding – before submission – is far cheaper than working denials after the fact.

• Wrong new/established status: Billing 99383 for an established patient who should be on 99393. Check the patient’s prior visit history and the three-year rule before assigning new patient status.
• Age boundary errors: Reporting 99383 for a child who turned 12 before the date of service. The correct code at 12+ is 99384 (new) or 99394 (established). Some practices use the patient’s age at the start of the year rather than the actual service date – this is incorrect.
• Same-day sick visit bundling without a modifier: When a problem-oriented E/M service is provided on the same day as the preventive visit, such as a new patient office visit (CPT 99202), modifier 25 must be appended to that E/M code (not to 99383) to indicate a significant, separately identifiable service. Without the modifier, payers will bundle or deny the second service.
• Incomplete documentation: Notes that lack individualized anticipatory guidance topics, or that omit developmental and behavioral assessment findings, fail audit review. Template-generated notes that are identical across patients are a particular red flag.
• Billing frequency conflicts: Most payers limit preventive visits to once per year for this age group. Submitting a second 99383 or 99393 within 12 months without payer pre-authorization will typically deny as duplicate or frequency exceeded.

Reviewing denial patterns by code helps practices identify systemic errors quickly. Automated billing workflows that flag age-code mismatches and missing modifiers before claim submission reduce the rework burden on billing staff. Practices that also invest in scheduling patients effectively – capturing date of birth verification and insurance status at booking – catch eligibility and status errors before they reach the coder.

Diagnosis codes to report with CPT code 99383

Preventive visits use Z-codes (ICD-10-CM) rather than problem-focused diagnosis codes. For CPT code 99383, the appropriate primary diagnosis code is:

• Z00.121 – Encounter for routine child health examination with abnormal findings
• Z00.129 – Encounter for routine child health examination without abnormal findings

Z00.121 applies when the examination reveals a new finding that requires further evaluation or management. Z00.129 is used when the visit is entirely within normal limits. Using Z00.121 when no abnormal finding is documented, or Z00.129 when one is, creates a clinical inconsistency that payers flag during review.

Additional ICD-10 codes for identified conditions, such as obesity, vision concerns, or behavioral findings, are listed as secondary diagnoses when the finding is addressed at the visit. HIPAA requires that all diagnosis codes submitted on a claim accurately reflect the services provided; see the HIPAA compliance framework for medical offices for documentation accuracy requirements.

How Pabau supports CPT code 99383 billing

Preventive visit coding errors often trace back to workflow breakdowns rather than a lack of coding knowledge. When age verification, new/established patient status, and diagnosis code selection happen manually at multiple points in the revenue cycle, errors compound. Pabau’s claims management software connects scheduling, documentation, and charge capture so coding decisions are informed by the data already in the patient record.

For pediatric and primary care practices running high-volume preventive schedules, direct primary care software integrations and automated eligibility checks at booking reduce the number of claims that reach submission with correctable errors. The result is fewer denial cycles and faster time to payment on preventive visit claims.

Pabau also supports digital intake forms that can be configured to capture Bright Futures-aligned history components before the appointment, reducing documentation burden on the provider and ensuring the note reflects a complete preventive encounter from the start.

Conclusion

CPT code 99383 is a straightforward code with a narrow set of eligibility requirements – but the billing errors around new/established patient status, age boundaries, and same-day modifier usage add up quickly in pediatric practices. Getting the documentation right the first time, from anticipatory guidance specifics to the correct Z-code, is what keeps preventive visit claims paid without rework.
