Pediatrics Billing Guide: Well-Child Visits, Vaccine Administration, Developmental Screening, Medicaid EPSDT, and Pediatric RCM

Well-Child Preventive Visit Codes

Well-child visits use age-specific preventive medicine codes: New patient well-child codes: 99381 — preventive medicine, new patient; infant younger than 1 year; 99382 — age 1-4 years; 99383 — age 5-11 years; 99384 — age 12-17 years; 99385 — age 18-39 years (adolescent/young adult); Established patient well-child codes: 99391 — established patient; infant younger than 1 year; 99392 — age 1-4 years; 99393 — age 5-11 years; 99394 — age 12-17 years; 99395 — age 18-39 years; Age selection: use the age of the patient on the date of service; for a patient who turns 1 year old next week, the code is still 99391 if the visit is before the birthday; Bright Futures schedule: the AAP's Bright Futures guidelines define the recommended well-child visit schedule: newborn visit (before hospital discharge or within 3-5 days); then at 1 month, 2 months, 4 months, 6 months, 9 months, 12 months, 15 months, 18 months, 24 months, 30 months, then annually from age 3 through 21; each well-child visit includes: comprehensive health and developmental history; comprehensive physical examination; age-specific developmental/behavioral assessment; anticipatory guidance; immunization review and administration; screening tests as recommended; What is included vs. separately billable in the well-child visit: included: the preventive history and physical examination; review of immunization status; routine anticipatory guidance; the pediatrician's counseling about the vaccines being administered; separately billable: vaccines themselves (using product-specific CPT codes); vaccine administration codes; developmental screening instruments (96160-96161, 96127); hearing and vision screening if separately performed and documented; lab tests ordered during the visit (lead screening, CBC, etc.).

Vaccine Administration Codes

Vaccine administration is separately billable in addition to the well-child visit preventive code: Vaccine administration codes with physician counseling (age 18 and under): 90460 — immunization administration through 18 years of age via any route of administration, with counseling by physician or other qualified health care professional; first or only component of each vaccine or toxoid administered; 90461 — each additional vaccine or toxoid component administered (add-on code); these codes require face-to-face counseling by the physician or QHP; counseling must be documented in the note; example: MMR vaccine (measles, mumps, rubella = 3 components): 90460 × 1 (first component) + 90461 × 2 (two additional components); DTaP (diphtheria, tetanus, acellular pertussis = 3 components): 90460 × 1 + 90461 × 2; Vaccine administration codes WITHOUT physician counseling, or for patients over 18: 90471 — immunization administration; 1 injection; each injection; 90472 — each additional injection (add-on); 90473 — intranasal or oral route; 1 administration; 90474 — each additional intranasal or oral administration; when to use 90471-90474 vs. 90460-90461: use 90460-90461 when the physician personally counseled the patient or parent about the vaccine at this visit; use 90471-90474 when no physician counseling was provided, or when administering vaccines to patients over 18 years old; Vaccine product codes: the vaccine itself is reported with a separate CPT product code in addition to the administration code: 90700 — DTaP vaccine, any formulation; 90707 — measles, mumps, and rubella virus vaccine (MMR), live; 90713 — poliovirus vaccine, inactivated (IPV); 90716 — varicella virus vaccine (VZV), live; 90723 — diphtheria, tetanus toxoids, acellular pertussis vaccine, hepatitis B, and poliovirus vaccine (DTaP-HepB-IPV); 90680 — rotavirus vaccine, pentavalent; 90685-90688 — influenza vaccine; 90644 — meningococcal group B vaccine; 90620 — meningococcal groups C and Y and haemophilus B tetanus; VFC (Vaccines for Children): federally supplied vaccines through VFC are provided to eligible children at no charge; the practice bills for vaccine administration only (not the vaccine product); VFC vaccines are billable using 90460-90461 or 90471-90474 — the administration codes are separately billable even when the vaccine product is free; confirm VFC billing rules by payer — Medicaid has specific VFC billing protocols.

Developmental and Behavioral Screenings

Multiple screening instruments used in pediatric well-child care are separately billable: Developmental screening codes: 96110 — developmental screening (e.g., developmental milestone survey, speech and language delay screen), with scoring and documentation, per standardized instrument; 96127 — brief emotional/behavioral assessment (e.g., depression inventory, attention-deficit/hyperactivity disorder [ADHD] scale), with scoring and documentation, per standardized instrument; Autism screening: M-CHAT (Modified Checklist for Autism in Toddlers): typically billed with 96110 at 18-month and 24-month well-child visits; ASQ (Ages and Stages Questionnaire): billable with 96110; ADOS (Autism Diagnostic Observation Schedule): billed with more comprehensive developmental evaluation codes 96112-96113; ADHD screening: Vanderbilt Assessment Scale: billed with 96127; Conners Rating Scale: billed with 96127; Depression screening (PHQ-9 for teens): 96127; Substance use screening (CRAFFT for adolescents): 96127; Each separate standardized instrument completed and scored at the same visit can be billed as an additional unit of 96127; documentation requirement: the screening instrument must be: administered (parent or patient completes the questionnaire); scored; interpreted; documented in the medical record; the score and clinical interpretation (normal, borderline, abnormal) must be in the note; Other separately billable pediatric screenings: 99174 — instrument-based ocular screening (photoscreening); 99177 — instrument-based ocular screening with on-site automated analysis; 92551 — pure tone audiometry (hearing screen); these are separately billable when performed during the well-child visit.

Medicaid and EPSDT

Medicaid's Early and Periodic Screening, Diagnostic and Treatment (EPSDT) program mandates comprehensive preventive services for children under 21: EPSDT coverage mandate: federal law requires state Medicaid programs to cover the full range of EPSDT-defined services for children; EPSDT includes: comprehensive well-child exams at the Bright Futures schedule; required screening components (vision, hearing, dental, developmental, mental health, lead, iron, tuberculosis, lipids, STI); immunizations; diagnostic services following positive screens; treatment services identified through EPSDT screening; EPSDT interperiodic visits: in addition to the scheduled well-child exams, Medicaid must cover additional visits when medically necessary — these are called interperiodic EPSDT visits; example: a child seen for illness is found to have development concerns during the sick visit; an interperiodic EPSDT well-child exam can be scheduled for a comprehensive developmental evaluation; Medicaid-specific billing: each state Medicaid program has its own EPSDT billing requirements; some states use EPSDT encounter codes (HCPCS T1015 — clinic encounter for EPSDT); others use standard CPT codes with the patient's Medicaid ID; lead screening reimbursement: 83655 — lead level, blood; lead screening is EPSDT-required and separately billable at the 12-month and 24-month well visits (and other risk-stratified visits); Medicaid managed care vs. fee-for-service: most Medicaid children are enrolled in managed care organizations (MCOs); the MCO may have capitation payments for PCPs that bundle most well-child services; vaccine administration may be separately billable even under capitated managed care; verify your state MCO contracts for bundled vs. separately billable services.

Pediatric Billing Denials and RCM

Pediatric practices face specific denial patterns tied to vaccine billing and preventive service coding: Common pediatric billing denials: wrong vaccine administration code: using 90471-90474 when the physician provided counseling (90460-90461 should have been used); or using 90460-90461 without documentation of counseling in the note; vaccine component count errors: counting vaccine components incorrectly for 90460-90461; DTaP-HepB-IPV (Pediarix) is 5 components = 90460 × 1 + 90461 × 4; incorrect component counts are a common audit finding; well-child visit frequency: billing two well-child visits within the same plan year without documentation of medical necessity; most commercial plans cover one well-child visit per year; Medicaid covers visits on the Bright Futures schedule which includes multiple visits in year 1; sick visit + preventive on same day: billing both a preventive code (99391-99395) and a problem-focused E&M (99213-99215) without Modifier 25 on the problem E&M; Modifier 25 is required when a significant separately identifiable problem is addressed at the same visit as a well-child exam; developmental screening documentation: billing 96110 or 96127 without a completed, scored screening instrument in the medical record; the instrument results must be documented; Pediatric RCM best practices: vaccine administration documentation: implement a documentation template that captures: each vaccine administered; route; site; lot number; NDC; counseling provided (yes/no); this documentation supports the 90460-90461 counseling codes and satisfies documentation requirements for VFC and state immunization registries; age-based code automation: configure the EHR to auto-suggest the correct well-child code based on the patient's age on the date of service; reduces age-selection errors.
