Updated: 23 hours ago
Pediatric billing in 2026 includes 288 new CPT codes, a 3.26% payment increase, stricter Medicaid EPSDT rules, and new vaccine counseling code 90482. Modifier 33 got clarified for preventive services, and well-child documentation standards tightened January 1st. Common denials stem from wrong age-specific codes, missing EPSDT documentation, and incorrect same-day sick/well billing.
If you're billing pediatrics right now, you're dealing with more changes than usual.
January brought 288 new CPT codes several that completely change how you bill well-child visits and vaccines. CMS approved payment increases but tweaked practice expense calculations hitting some pediatric offices hard. And Medicaid EPSDT documentation standards that went live January 1st? Brutal.
Most pediatricians haven't had time to dig through this. You're slammed with back-to-back visits and parents Googling medical advice. But outdated codes and incomplete notes cost thousands in denials before you notice.
Here's everything that matters: which CPT changes you can't ignore, what payers demand for documentation, common denial traps, and how to actually get paid.
CPT Code Changes That Hit Your Revenue
Modifier 33 Finally Makes Sense
Modifier 33 tells payers "this is preventive no copay." But nobody was clear on when to use it.
What changed: Description now says you append modifier 33 when the primary purpose is delivering evidence-based preventive services with USPSTF A or B rating—or services under programs like Medicaid EPSDT.
Why it matters: You do a behavioral screening (96127) during a well visit for a 12-year-old. If it's outside "recommended" age but still preventive, modifier 33 signals no cost-sharing.
Don't do this: Slap modifier 33 on codes already labeled preventive. Only use it to flag ancillary services during preventive visits.
New Vaccine Counseling Code (Huge)
90482 is massive: "Immunization counseling when immunization isn't administered same date; 3-10 minutes."
Parents increasingly want counseling sessions before deciding on vaccines. Before, you couldn't bill for counseling when no shot was given. Now you can—telehealth approved too.
Real scenario: Mom brings her 5-year-old for a cough. She asks about HPV vaccine she's been avoiding. You spend 8 minutes on safety questions, but she's not ready. Bill 90482 for that time. Money you used to give away.
Other vaccine updates:
90593: Chikungunya virus immunization (FDA-approved, commercially available)
90480/90481: Revised for future multi-antigen vaccines including SARS-CoV-2
Remote Monitoring Gets Flexible
Five new RPM codes let you report monitoring for 2-15 days within 30 days instead of 16-day minimum.
For kids with asthma flare-ups or diabetes needing close glucose monitoring, remote care is now financially practical.
ICD-10 Codes That Cause Denials
Well-Child Visit Diagnosis
Use Z00.12- codes based on findings:
Z00.121: With abnormal findings
Z00.129: Without abnormal findings
Killer mistake: Billing Z00.129 when notes say "elevated BMI" or "developmental delay." That mismatch is audit bait.
Behavioral Screening Codes
Match diagnosis to what you screened:
Z13.4: Developmental delays (under 5)
Z13.31: Depression screening
Z13.32: Maternal depression
Z13.39: Other mental health screening
Pair with CPT: 96110 (developmental), 96127 (emotional/behavioral).
Vaccine Diagnosis Codes
Z23: Encounter for immunization
Z28.1: Not given due to contraindication
Z28.2: Patient declined (perfect for counseling-only visits)
CMS Payment Changes
The Payment Bump
Most physicians see 3.26% increase. APM participants get 3.77%.
Conversion factors:
Non-APM: $33.40
APM: $33.57
But here's the catch.
Practice Expense Tweaks
CMS adjusted practice expense calculations. Some pediatric procedures especially hospital-based saw cuts despite overall increases.
What to do: Compare your top 20 codes to last year. If specific codes dropped significantly, consider changing service location or documentation.
Telehealth's Shaky Future
Many flexibilities are permanent virtual supervision included. But some provisions only extended through January 30, 2026.
Behavioral health integration, chronic care management, and developmental assessments can continue via telehealth for now. Congress needs to act for extensions beyond January.
Billing Mistakes Killing Revenue
Same-Day Sick and Well Visits
You can bill both only if the sick visit needs substantial separate work beyond the well-child exam.
Wrong way: Mom mentions kid's cough during well-child check. You automatically bill both.
Right way: Bill preventive visit (99383, etc.) and add modifier 25 to problem-focused code only when sick visit involves genuinely separate evaluation.
Documentation fix: Keep them totally separate in notes. One section covers well-child stuff. Completely different section addresses acute problem.
Wrong Age-Specific Codes
Pick wrong age bracket, claim denied instantly.
Established patient preventive:
99391: Under 1 year
99392: 1-4 years
99393: 5-11 years
99394: 12-17 years
Mistake: Billing 99392 for 5-year-old's well-child visit. That's 1-4 years. You needed 99393.
Screening Code Errors
96110 (developmental): Often limited to once yearly or per AAP schedule.
96127 (emotional/behavioral): Can bill multiple times per visit for different screenings, but document what each assessed.
Mistake: Billing 96127 three times without notes explaining each separate screening. Payers pay one, deny rest.
Vaccine Billing Screwups
Bill product (90476-90749) and administration (90460-90461 with counseling, 90471-90474 without).
Common errors:
Forgetting administration (free work)
Administration codes not matching vaccine components
Using counseling codes without documentation
Example: 15-month-old gets DTaP, IPV, MMR with counseling.
90460 (first vaccine with counseling)
90461 x2 (two additional with counseling)
Plus product codes
Medicaid EPSDT Gaps
Must document:
Comprehensive health/developmental history
Complete unclothed physical
Age-appropriate immunizations
Required labs (lead, anemia)
Health education/anticipatory guidance
Vision/hearing screening
Dental referral
Mistake: "Well-child exam performed" without documenting each element. Medicaid auditors deny.

Questions You're Asking
What's the difference between 99213 and 99214? 99214 requires moderate complexity versus low for 99213. Time also differs: 99213 is 20-29 minutes, 99214 is 30-39 minutes.
Can I bill well-child and sick visits same day? Yes, but only when sick visit needs significant separate work. Document separately and add modifier 25 to sick visit code.
How often can I bill developmental screening 96110? Varies by payer. Commercial plans often allow once yearly. Medicaid varies by state—some allow more for high-risk kids.
Do well-child visits need authorization? Usually not for commercial plans. Some Medicaid managed care requires it. Always verify first.
Can I bill counseling codes for brief vaccine talks? 90460-90461 don't have time thresholds but require face-to-face counseling about benefits, risks, side effects. If counseling happened, use these codes.
What diagnosis for well-child visits? Z00.121 (with abnormal findings) or Z00.129 (without) depending on exam findings.
How do I bill vaccine counseling when parents decline? Use code 90482 for counseling when immunization isn't given. Document 3-10 minutes spent and topics discussed. Use diagnosis Z28.2.
Stop Losing Money on Billing Mistakes
Pediatric billing keeps getting messier. New codes, changing rates, stricter requirements more chances for expensive mistakes.
Practices handling changes smoothly aren't trying to keep up themselves. They work with billing specialists who make compliance someone else's problem.
