Denial
MassHealth ACO mismatch
Root cause in Greater Boston
Child assigned to a different accountable-care partner
How we close it
Eligibility run at every encounter
Pediatric billing · Boston, MA
Pediatric billing services in Boston have to move fluently between MassHealth accountable-care plans and one of the richest commercial markets in the country, and 247 Medical Billing Services (247MBS) runs that mixed revenue cycle so children's practices are paid on the first pass. Since 2005 we have billed well-child, immunization, and newborn claims for Greater Boston pediatricians, filing to MassHealth ACOs and MCOs alongside the region's dominant commercial carriers. Every client gets a dedicated account manager and a free 360° dashboard, and we operate HIPAA-compliant and SOC 2 Type II certified across Suffolk County and the surrounding metro.
In a market this mixed, the most expensive denials are the quiet ones — a routine visit filed under the wrong MassHealth ACO, or a same-day sick problem the commercial payer bounces for a documentation gap. High volume turns each small leak into real money.

Clean coding on the front end is what keeps a mixed 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 MassHealth plan or commercial contract.
| Service line | Codes | What the claim must prove |
|---|---|---|
| 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 |
Boston is anchored by Boston Children's Hospital and Mass General for Children, and the community pediatricians who orbit those systems work one of the most distinctive payer landscapes in the country. Public coverage runs through MassHealth, the state's Medicaid and CHIP program, which has largely moved to accountable-care organizations — so a child's "Medicaid" is really an ACO partnership with its own referral, eligibility, and documentation rules. At the same time, Greater Boston carries an unusually high commercial share through carriers like Blue Cross Blue Shield of Massachusetts, Harvard Pilgrim, and Tufts, each with its own preventive-visit and vaccine edits. That split is the defining challenge: a practice cannot standardize on one payer's logic, because half its well-child visits follow ACO rules and half follow a commercial contract. Eligibility churns as families shift between ACOs at renewal, and academic-adjacent neighborhoods add frequent coverage changes as households move for school and work. A billing company that treats Boston as a single commercial market will misfile the MassHealth half, and one that treats it as pure Medicaid will fumble the commercial contracts. Getting paid here means reading each child's plan correctly, every time, before the claim goes out.

Practices choose to outsource when the front desk can no longer verify MassHealth ACO assignment, reconcile commercial contracts, 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 both MassHealth and the region's commercial carriers rather than treating children's claims as an afterthought.
Outsourcing also gives Boston 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 ACOs and commercial plans before the first claim goes out. For the full overview, see our pediatric billing hub; for statewide payer detail, see medical billing in Massachusetts. As a billing services company built around children's care, our 98% client retention reflects how much that specialty focus matters.
We bill for solo and independent pediatricians, multi-site pediatric groups, and pediatric urgent care from the South End and Dorchester out to Cambridge, Somerville, Brookline, Quincy, and Newton. That includes newborn and hospitalist pediatric services tied to the city's academic children's programs, high-volume vaccine clinics, practices carrying blended MassHealth and commercial panels, and offices adding a clinician who needs credentialing before that provider can bill. Whether your patients lean accountable-care Medicaid or premium commercial coverage, we match the workflow to how they are actually covered instead of forcing one template onto pediatric claims.
Medical billing for pediatric in Boston keeps a Greater Boston practice paid across a split panel where half the well-child visits follow MassHealth accountable-care rules and half follow a commercial contract. 247MBS reads each child's active plan before the visit, codes preventive, vaccine, and same-day sick lines to the payer that will actually pay them, and submits within 24 hours so nothing lapses on a deadline. Practices from the South End and Dorchester to Cambridge and Newton see up to 40% fewer denials and A/R days held under 25 once specialist pediatric coders take over. In a Boston Children's and Mass General for Children market this mixed, that precision is what stops routine visits from quietly leaking. Request a revenue review.
Boston practices are billed out of the same Massachusetts desk. Statewide payer detail lives on the Massachusetts page.
Pediatric Billing Services provider — the codes, unit rules and denials nationally, without the local layer.
Yes. We verify the child's active MassHealth accountable-care assignment or commercial contract before every visit and file well-child and immunization claims to the correct plan, which is where most Boston 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 report developmental and behavioral screens separately from the preventive visit, so state-supplied vaccines and screening lines both pay instead of bundling away.
From solo practices to multi-provider groups, we bill Pediatric for Boston 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.
