Pediatric billing · Chicago, IL
Pediatric billing services in Chicago have to run on HealthChoice Illinois rules across one of the most diverse patient populations in the country, and 247 Medical Billing Services (247MBS) manages that revenue cycle so children's practices are paid on the first pass. Since 2005 we have billed well-child, immunization, and newborn claims for Chicago pediatricians, filing to the HealthChoice Illinois managed-care plans and the All Kids CHIP program alongside commercial payers. Every client gets a dedicated account manager and a free 360° dashboard, and we operate HIPAA-compliant and SOC 2 Type II certified across Cook County and the collar suburbs.
We bill for solo and independent pediatricians, multi-site pediatric groups, and pediatric urgent care from Lincoln Park and Pilsen out to Evanston, Oak Park, Cicero, Skokie, Naperville, and Aurora. That includes newborn and hospitalist pediatric services connected to the region's academic children's programs, high-volume vaccine clinics, practices carrying heavy HealthChoice Illinois and All Kids panels, and offices adding a clinician who needs managed-care credentialing before that provider can bill. Chicago's neighborhoods span every payer profile, from dense All Kids and Medicaid populations to commercially insured North Shore families, and many of our Illinois clients came to us after a generalist biller struggled to keep those different plan rules straight. Whether your panel leans public managed Medicaid, a commercial suburban mix, or both in the same week, we build the workflow around how your patients are actually covered instead of forcing one template onto pediatric claims.
Clean coding on the front end is what keeps a mixed, high-volume panel moving. A single well-child appointment often stacks a preventive visit, several vaccine lines, a developmental screen, and a same-day sick complaint, and each layer has to match the child's specific HealthChoice Illinois plan or commercial contract.
| Service line | Codes | Requirement to pay |
|---|---|---|
| Preventive, new patient | 99381–99385 | Age band matches the child's date of birth |
| Preventive, established | 99391–99395 | Correct band; periodicity schedule respected |
| Well visit plus sick, same day | 99202–99215 + modifier 25 | Separate acute problem documented |
| Vaccine admin with counseling | 90460 / 90461 | First and each-additional component counted |
| Vaccine admin without counseling | 90471–90474 | Billed only when no counseling is provided |
| VFC state-supplied vaccine | admin + SL modifier | State stock, administration line only |
| Newborn care | 99460–99463 | Correct site; 99464 / 99465 billed separately |
| Developmental / behavioral screen | 96110 / 96127 | Reported separately, not bundled into the visit |
Chicago is home to the Ann & Robert H. Lurie Children's Hospital and Comer Children's Hospital at the University of Chicago, and the community pediatricians who share those referral networks bill a payer landscape defined by scale and diversity. Illinois delivers children's Medicaid through HealthChoice Illinois, a managed-care model with several competing plans, and layers the All Kids program on top to cover children across a broad income range — including families who would fall outside Medicaid in many other states. That breadth means a single Chicago practice can see All Kids, standard Medicaid managed care, and premium commercial coverage in one day, each with its own eligibility portal, EPSDT documentation standards, and vaccine administration edits. The city's linguistic and immigrant diversity adds first-visit enrollment and coverage-change work that a generalist office underestimates, and eligibility churns constantly as families move between plans at renewal. A billing company that flattens all of this into one payer will misroute a meaningful share of everyday well-child and vaccine visits — and in pediatrics, those routine visits carry the practice. Billing Chicago well means reading each child's plan correctly, every time, before submission.

The denials here follow the managed-Medicaid pattern, sharpened by the number of plans in play: everyday well-child and vaccine lines undone by a plan mismatch or a missing modifier, then multiplied by very high encounter volume.

Practices choose to outsource when the front desk can no longer verify several HealthChoice Illinois plans, sort All Kids from standard Medicaid, reconcile VFC, and work denials in the same shift. As a dedicated pediatric billing company, we own the full cycle: eligibility, coding, claim scrubbing, submission within 24 hours, and denial recovery. Our numbers hold up across the metro — a 99% first-pass clean-claim rate, up to 40% fewer denials, 90% of worked denials recovered, and A/R days kept under 25. We are a medical billing services company that runs pediatrics as a specialty line, with professional coders who know HealthChoice Illinois and All Kids rather than treating children's claims as an afterthought.
Outsourcing also gives Chicago practices clean service handoffs instead of one overloaded biller. Clients rely on our eligibility and verification, denial management, and pediatric credentialing so a new provider is paneled with the HealthChoice Illinois plans before the first claim goes out. For the full overview, see our pediatric billing hub; for statewide payer detail, see medical billing in Illinois. As a billing services company built around children's care, our 98% client retention reflects how much that specialty focus matters.
Medical billing for pediatric in Chicago keeps a high-volume Cook County practice paid when a single day can bring All Kids, standard HealthChoice Illinois managed care, and premium commercial coverage through the same waiting room. 247MBS reads each child's exact plan before the visit, codes EPSDT well-child and VFC lines to the payer that will actually pay them, and submits within 24 hours so nothing lapses on a plan deadline. Practices from Lincoln Park and Pilsen to Evanston and Naperville see up to 40% fewer denials and A/R days held under 25 once specialist pediatric coders take over. In a Lurie and Comer Children's market this diverse, that plan-by-plan precision is what protects the routine visits that carry the practice. Request a revenue review.

Outsource Pediatric Billing — the codes, unit rules and denials nationally, without the local layer.
Yes. We verify the child's active HealthChoice Illinois managed-care plan or All Kids coverage before every visit and file EPSDT well-child and immunization claims to the correct plan, which is where most Chicago pediatric denials start.
Yes, and it is one of the most common pediatric fixes we make. We confirm the same-day sick problem is separately documented before submission, so both the well visit and the problem E&M are paid.
We do. We bill VFC administration with the SL modifier and align well-child claims to the Bright Futures periodicity behind Illinois's EPSDT benefit, so state-supplied vaccines and preventive visits both pay correctly.
From solo practices to multi-provider groups, we bill Pediatric for Chicago practices with a dedicated account manager, certified coders and a live dashboard — so the units, authorizations and appeals that decide your month stop being the thing nobody has time for.
