What Is Pediatric Billing and Coding?

Pediatric billing and coding involves applying the correct CPT, ICD-10, and HCPCS codes for patients from newborns to adolescents to ensure accurate communication with payers and proper reimbursement. It requires a strong understanding of age-specific codes, procedural nuances, and documentation standards.

Pediatrics covers the physical, mental, and social health of children from birth to young adulthood, across specialties such as neonatology, pediatric emergency medicine, critical care, cardiology, rheumatology, pulmonology, and developmental-behavioral pediatrics. Understanding the unique needs of each age group is essential for coding professionals to submit accurate claims and ensure timely reimbursement.

Below is a breakdown of age groups commonly used in pediatric billing, serving as a reference for selecting appropriate codes for each patient population:

With a clear understanding of age groups and specialties, the next step is to review the common pediatric billing and procedure codes used for accurate claims submission.

Key Pediatric Billing and Procedure Codes for Accurate Claims

Accurate pediatric billing relies on selecting the correct codes for evaluation, preventive care, and procedures. E&M codes are essential for documenting patient encounters, with the choice of code reflecting the visit’s complexity, duration, and the patient’s medical needs. Preventive medicine codes encompass routine well-child visits, growth assessments, and immunizations, all of which are crucial for maintaining a child's overall health.

In addition, procedure codes cover pediatric-specific interventions, surgical procedures, and treatments unique to this population. Understanding these codes ensures claims are correctly submitted, reduces denials, and supports compliance with payer requirements.

Key Pediatric Codes:

• 54150: Circumcision performed using a clamp or other device.
• 54160: Surgical circumcision procedures.
• 36510: Insertion of a central venous catheter.
• 90460: Vaccine administration with counseling for the patient or caregiver.
• 90461: Vaccine administration without counseling.
• 99202–99205: Office or outpatient visits for new patients, coded according to complexity and services provided.
• 99211–99215: Office or outpatient visits for established patients, selected based on visit level and clinical requirements.
• 99381–99384: Preventive visits for new patients, covering growth, development, and initial health assessments.
• 99391–99394: Preventive visits for established patients, including routine check-ups, immunizations, and counseling.

Example: A 4-year-old established patient comes in for a routine well-child visit with immunizations. The coder selects 99392 for the preventive visit and 90461 for vaccine administration without counseling. Proper coding ensures the claim is approved without denials.

The codes are organized by patient age and whether the patient is new or established to the practice. This framework aligns with the American Academy of Pediatrics' Pediatric Billing and Coding Guidelines, enabling practices to reduce denials and maintain compliance.

Let’s review the essential pediatric vaccine codes that ensure accurate billing, proper documentation, and timely reimbursement for preventive care services.

Essential Pediatric Vaccine Codes for Accurate Billing

Vaccination is a critical component of pediatric care, and accurate coding ensures proper documentation, timely reimbursement, and compliance with preventive care guidelines. Using the correct vaccine codes also reduces claim denials and supports the overall revenue cycle.

Key Pediatric Vaccine Codes:

• 90686: Influenza virus vaccine, quadrivalent (IIV4), split virus, preservative-free, 0.5 mL, intramuscular use.
• 90688: Influenza virus vaccine, quadrivalent (IIV4), split virus, 0.5 mL, intramuscular use.
• 91318: SARS-CoV-2 (COVID-19) mRNA-LNP vaccine, 3 mcg/0.3 mL, tris-sucrose formulation, intramuscular use.
• 90633: Hepatitis A (HepA) vaccine, pediatric/adolescent, 2-dose schedule, intramuscular use.
• 90744: Hepatitis B vaccine, pediatric/adolescent, 3-dose schedule, intramuscular use.
• 90707: Measles, mumps, and rubella (MMR) vaccine, live, subcutaneous use.

Example: A 6-month-old receives the Hepatitis B and DTaP vaccines in a single visit. The coder should report:

• 90744 for the Hepatitis B vaccine (pediatric/adolescent dosage, 3-dose schedule, for IM use)
• 90700 for the DTaP vaccine (Diphtheria, tetanus toxoids, and acellular pertussis vaccine, when administered to children under 7 years, for IM use)
• 90461 for the administration of each additional vaccine component beyond the first, without counseling.

This coding approach ensures that both vaccines are reimbursed correctly and complies with the guidelines of the American Academy of Pediatrics.

For detailed information and updates on pediatric vaccine coding, you can refer to the AAP Immunization Coding Table, which lists all the correct codes for accurate claim submission.
