Running a pediatric practice is rewarding yet highly challenging, especially when it comes to managing medical billing. Pediatric care involves everything from routine well-child visits to immunizations, developmental screenings, and urgent care visits. Each of these services requires accurate coding and proper claim submission to ensure timely reimbursement. In California, this process is even more complex due to Medi-Cal, private insurance rules, and the state’s strict healthcare regulations.
This is where pediatric billing experts serving California make a difference. They provide specialized billing services that ensure accuracy, compliance, and efficiency in the revenue cycle.
Why Pediatric Billing Is Unique
Unlike other specialties, pediatrics deals with a wide range of patient needs, ages, and frequent visits. Pediatric billing requires:
Age-specific coding – Preventive care visits are coded differently depending on whether the child is an infant, toddler, or teenager.
Vaccine administration billing – Vaccinations require multiple CPT codes for the vaccine itself and for administration with counseling.
Coordination of benefits (COB) – Often, children are covered under more than one insurance plan (both parents’ coverage), making claims more complex.
Frequent preventive visits – Well-child visits and screenings occur multiple times a year, requiring accurate documentation to avoid denials.
High reliance on Medicaid/Medi-Cal – A large percentage of California’s pediatric population is covered under Medi-Cal, which has unique billing requirements.
Because of these complexities, many pediatric practices in California choose to outsource billing to professionals who understand both pediatric medical billing services and California-specific payer rules.
Common Challenges in Pediatric Billing
1. Vaccine Billing Errors
Immunizations are one of the most frequent services in pediatrics. Errors occur when practices bill only for the vaccine but not for its administration, or use the wrong CPT code.
2. Age-Specific Preventive Visit Coding
For example:
CPT 99381 – Initial preventive visit for patients under 1 year
CPT 99382 – Ages 1–4 years
CPT 99383 – Ages 5–11 years
CPT 99384 – Ages 12–17 years
Mixing these up leads to denials or underpayments.
3. Coordination of Benefits Issues
When both parents have insurance, improper handling of COB causes claim delays. Billing experts ensure the correct primary vs. secondary payer sequence.
4. Medi-Cal Claim Rejections
Medi-Cal has strict requirements on documentation, code usage, and timely filing. Non-compliance results in frequent rejections.
5. Telehealth Pediatric Billing
Since COVID-19, telehealth visits have grown, but pediatric practices often miss using modifiers like 95 for virtual visits.
Key Pediatric Billing Codes
Here are the most frequently used pediatric billing CPT codes:
Preventive Visits (Well-Child Exams):
CPT 99381–99385 – Initial preventive visits by age
CPT 99391–99395 – Periodic preventive visits by age
Sick Visits:
CPT 99213 – Established patient, low complexity
CPT 99214 – Established patient, moderate complexity
Vaccines Immunizations:
CPT 90460–90461 – Immunization administration with counseling
CPT 90633 – Hepatitis A
CPT 90707 – MMR
CPT 90716 – Varicella
Screenings Other Pediatric Services:
CPT 96110 – Developmental testing
CPT 36415 – Collection of venous blood (lab work)
Billing experts ensure these codes are used correctly along with proper ICD-10 diagnosis codes.
Pediatric Billing Medi-Cal in California
Medi-Cal is one of the largest Medicaid programs in the U.S., covering millions of children. Pediatric billing experts serving must understand:
EPSDT (Early and Periodic Screening, Diagnostic, and Treatment) Services – Required screenings and treatments for children under Medicaid.
Managed Care Plans – Many Medi-Cal patients are under managed care, requiring specific claim submission portals.
Reimbursement Limitations – Certain pediatric codes are reimbursed differently under Medi-Cal.
Documentation Requirements – Strict rules for well-child visits, vaccines, and screenings.
An expert billing partner ensures compliance with Medi-Cal’s policies, reducing rejections.
