Direct Answer
Pediatric billing is distinct from adult medicine billing in several important ways: well-child visit preventive care codes are age-banded (infants have different codes than adolescents), vaccine administration requires both an administration CPT code and a vaccine product HCPCS code, Medicaid's EPSDT mandate covers a broader set of preventive services than commercial insurance, and CHIP (Children's Health Insurance Program) has its own coverage and billing rules. Many pediatric practices serve a high-Medicaid patient population, making Medicaid managed care contracting and EPSDT compliance central to the revenue cycle.

Well-Child Visit Codes
Well-child visits (preventive care) use age-banded CPT codes from the preventive medicine services range (99381–99395): New patient preventive medicine codes (99381–99387): 99381 — Infant, younger than 1 year; 99382 — Early childhood, age 1–4 years; 99383 — Late childhood, age 5–11 years; 99384 — Adolescent, age 12–17 years; 99385 — 18–39 years (for adult patients); Established patient preventive medicine codes (99391–99395): 99391 — Infant, younger than 1 year; 99392 — Early childhood, age 1–4 years; 99393 — Late childhood, age 5–11 years; 99394 — Adolescent, age 12–17 years; 99395 — 18–39 years; What well-child visits include: comprehensive history (birth/developmental/medical/family/social); comprehensive physical examination appropriate to age; anticipatory guidance (age-appropriate counseling); ordering and review of recommended screening tests; vision, hearing, and developmental screening; BMI calculation for age 2+; blood pressure measurement for age 3+; Billing same-day sick visit and well-child: when a patient presents for a well-child visit but the provider also addresses a new or existing medical problem that requires additional work beyond the preventive service scope: the well-child code is billed as the primary code; an E&M code (99213 or appropriate level) is billed in addition with Modifier 25; the E&M must represent a significant, separately identifiable service; documentation must distinguish the preventive care content from the sick-visit content; a patient presenting for a 4-year well-child visit and being diagnosed with strep throat and treated accordingly supports billing both 99382 and 99213-25.
Vaccine Administration and Product Codes
Vaccine billing requires two components: the administration code (CPT) and the vaccine product code (typically HCPCS): Vaccine administration CPT codes: 90460 — Immunization administration through 18 years of age via any route of administration, with physician or other qualified health care professional counseling; first or only component of each vaccine or toxoid administered; 90461 — Each additional vaccine or toxoid component administered (add-on to 90460); 90471 — Immunization administration, one vaccine (intramuscular, subcutaneous, intranasal, or oral) without counseling; 90472 — Each additional vaccine administration without counseling; When to use 90460 vs. 90471: 90460/90461 (with counseling) requires the physician or QHP to personally provide and document age- and vaccine-specific counseling to the patient and/or parent; the counseling must be documented in the record; 90471/90472 (without counseling) is used when no physician/QHP vaccine counseling is provided — the counseling is provided by another staff member using a VIS sheet without physician involvement, or there is no such interaction; Vaccine product HCPCS codes: each specific vaccine has an assigned HCPCS code (e.g., 90700 — DTaP; 90707 — MMR; 90714 — Td; 90716 — Varicella; 90723 — DTaP-HepB-IPV; 90734 — Meningococcal; 90746 — Hepatitis B, adult; 90647 — HiB); the product code is reported in addition to the administration code; Vaccines for Children (VFC) program: pediatric practices that participate in the VFC program receive free vaccines for eligible patients (Medicaid, CHIP, uninsured, or underinsured); VFC vaccines are not billed to payers — the product is free and only the administration fee is billed; non-VFC vaccines (administered to commercially insured patients) are billed with both the product code and the administration code; practices must maintain separate VFC and non-VFC vaccine inventories.
EPSDT Under Medicaid
The Early and Periodic Screening, Diagnostic, and Treatment (EPSDT) benefit is a mandatory Medicaid benefit for all children under 21 that provides comprehensive preventive health services: What EPSDT covers: comprehensive health and developmental history; comprehensive unclothed physical examination; immunizations; vision services; hearing services; dental services; laboratory tests (including lead blood level assessment); health education; any other medically necessary service (this is the most important aspect — EPSDT requires states to cover any service that is medically necessary for the child even if the service is not covered in the state's adult Medicaid plan); The "mandatory coverage" provision: if a child needs a service and it is medically necessary, Medicaid must pay for it under EPSDT — even if the state hasn't otherwise included that service in its Medicaid package; this is significantly broader coverage than commercial insurance; EPSDT screening periodicity schedule: each state Medicaid program publishes a periodicity schedule for required screenings; most align with the AAP (American Academy of Pediatrics) and Bright Futures periodicity schedule; well-child visits at birth and follow-ups: newborn, 3–5 days, 1 month, 2 months, 4 months, 6 months, 9 months, 12 months, 15 months, 18 months, 24 months, 30 months, and annually from ages 3 through 21; EPSDT billing: EPSDT services are reported with the standard well-child visit preventive care codes; some states require reporting an EPSDT indicator on the claim (Box 24H on the CMS-1500 or the equivalent field); confirm state-specific EPSDT reporting requirements; Developmental screening: Medicaid covers developmental screening under EPSDT; codes: 96110 — Developmental screening; 96127 — Brief emotional/behavioral assessment (screen); 96161 — Administration of caregiver-focused health risk assessment instrument; many pediatric practices under-bill for developmental and behavioral screening that is separately reportable under Medicaid.
CHIP Billing
The Children's Health Insurance Program (CHIP) covers children who are not eligible for Medicaid but whose family income is too high to afford private insurance: CHIP coverage structure: CHIP is jointly funded by the federal government and states; each state runs its own CHIP program, either as a Medicaid expansion or as a separate stand-alone program or a combination; states set their own benefit packages within federal minimum standards; CHIP benefits are typically more similar to commercial insurance than to Medicaid — beneficiaries may have copays and cost-sharing; CHIP billing vs. Medicaid billing: separate CHIP claims may be submitted to a different payer ID than the state's fee-for-service Medicaid; if the state has contracted CHIP administration to a managed care organization (MCO), the practice bills the MCO directly; eligibility verification is critical — CHIP and Medicaid are different programs and a patient enrolled in CHIP is not enrolled in Medicaid; CHIP cost-sharing: unlike Medicaid (which prohibits most cost-sharing for children), CHIP allows states to impose premiums and copays for families above 150% of the federal poverty level; preventive services (EPSDT-equivalent) under CHIP are generally exempt from cost-sharing; practices should verify the patient's CHIP cost-sharing obligations at eligibility verification; CHIP redetermination: CHIP coverage is redetermined annually; during the COVID-19 PHE, states were prohibited from disenrolling Medicaid/CHIP beneficiaries (continuous enrollment); when the PHE ended and continuous enrollment ended (2023), many children had CHIP/Medicaid coverage disrupted during the redetermination process; practices should proactively verify CHIP eligibility at each visit during and after major redetermination periods.
Sick Visit and Problem-Oriented Coding
Pediatric sick visits use standard E&M CPT codes — the same codes used for adult office visits: Established patient office/outpatient visit codes: 99212–99215: the same office visit codes as for adult patients; pediatric coding does not use a different set of E&M codes for acute illness visits; 2021 E&M guidelines apply: coding level is determined by either MDM (Medical Decision Making) or total time; for pediatric visits, MDM is typically used — the complexity of the problem, data reviewed, and risk of management; Neonatal and pediatric critical care: 99468–99469 — Neonatal critical care (initial day; subsequent); 99471–99476 — Pediatric critical care (ages 29 days–71 months and 6–17 years); these are global per-day codes (similar to hospital observation per-day codes) and include virtually all services provided during the critical care day; Neonatal intensive care (NICU): 99477 — Neonatal intensive care, initial inpatient (first day, low birth weight, 28–31 weeks); 99478–99480 — subsequent NICU care by weight category; Newborn hospital care: 99460–99463 — Newborn care in a hospital or birthing center (initial; subsequent; normal newborn discharge); these are distinct from adult hospital care codes; Pediatric E&M documentation tips: for very young patients (infants, toddlers), the history is obtained from the parent/caregiver; document the historian (e.g., "history obtained from mother"); developmental history is a component of the pediatric history not present in adult visits; growth and developmental surveillance documentation supports well-child preventive codes.
FAQ
How should a pediatric practice handle same-day billing for a well-child visit combined with a sick visit?
Same-day well-child plus sick visit billing is one of the most common pediatric billing questions and a frequent audit area. The rules are clear but require careful documentation: When same-day billing is appropriate: the sick visit problem must be a significant, separately identifiable service beyond the scope of the preventive care visit; examples of valid combinations: 4-year well-child visit PLUS same-day acute otitis media diagnosis and antibiotic prescription; 12-year adolescent physical PLUS same-day evaluation of a new rash; 18-month well-child PLUS same-day weight loss concern with evaluation and new feeding plan; Examples where same-day E&M billing is NOT appropriate: discussing a chronic condition that is simply noted as stable during the physical without additional evaluation; noting that the patient is currently on medication without any change in management; reviewing a previously ordered lab result that is normal without significant clinical decision-making; Billing mechanics: bill the well-child visit code (e.g., 99392) as the primary code; bill the appropriate E&M code for the sick visit (e.g., 99213) as a secondary code with Modifier 25; the E&M should be coded at the level supported by the documentation of the sick visit component only; Documentation requirements: the note must clearly delineate the preventive care content from the sick visit content; many EHR systems generate a combined note — ensure the sick visit clinical decision-making is separately documented; auditors look for: a separately documented chief complaint for the sick visit problem; documentation of the evaluation of the sick visit problem (assessment and plan); clinical decision-making that supports the E&M level billed; ACA preventive care and cost-sharing: preventive services (well-child visits) are covered at 100% under the ACA with no cost-sharing for most commercial plans; the sick visit E&M may be subject to deductible or copay; accurately separating the two services on the claim ensures the patient's cost-sharing is applied correctly.
What developmental screening codes can a pediatric practice bill, and what documentation is required?
Developmental and behavioral screening in pediatrics is significantly under-billed — many practices perform these screenings as part of the well-child visit without billing them separately. The following codes can be separately reported when the specific screening instruments are administered and interpreted: 96110 — Developmental Screening: administration of a standardized developmental screening instrument (e.g., Ages and Stages Questionnaire [ASQ], Parents Evaluation of Developmental Status [PEDS], Modified Checklist for Autism in Toddlers [M-CHAT]); interpretation and report; reported per standardized instrument; some payers limit to one per visit or per year; 96127 — Brief Emotional/Behavioral Assessment: administration of a standardized brief assessment instrument (e.g., Pediatric Symptom Checklist [PSC], CRAFT screen for adolescents, PHQ-A for adolescent depression, SCARED for anxiety); interpretation and report; 96161 — Administration of Caregiver-Focused Health Risk Assessment Instrument: a caregiver-completed standardized screening instrument focused on risk factors in the family context; Documentation requirements: the specific instrument used must be named in the documentation (do not just document "developmental screen performed"); the score or result must be documented; the interpretation and clinical implications must be documented; the name of who administered the instrument (nurse, MA, or physician) should be documented; the parent/caregiver education or follow-up action plan should be documented for positive screens; Payer coverage rules: most commercial plans cover 96110 and 96127 as part of well-child visits; Medicaid covers developmental screening under EPSDT; some payers bundle these codes into the well-child visit payment (no separate reimbursement); practices should verify payer-specific coverage and reimbursement for these codes before billing; the AAP recommends documenting why a specific tool was selected and how results were communicated to the family — this documentation also supports billing in audits.
