Pediatric billing looks simple until you read the denial report. The visits are short, the codes are familiar, and most of the revenue comes from well-child checks and sick visits. Then a preventive visit and a sick visit land on the same day, and whether the second one gets paid depends on a modifier 25 that one plan demands and another rejects. Vaccines are billed twice, once for the product and once for giving it, and counseling codes only apply when the provider actually counsels. Preventive codes also change with the child's age, so a check booked as a one-year visit that happens a week after the birthday needs fixing before the claim goes out.
The real losses sit in the small add-on codes. Developmental screening, behavioral screening, vision and hearing tests, fluoride varnish: Medicaid and CHIP plans each have their own rules for these, and front desk staff either skip them or bill them once, get denied once, and never look again. Per visit it is little. Vaccines are the other soft spot. You buy the product, it sits on your shelf, and payment comes back late or below what the order cost. Stock from the free vaccine program has separate billing rules, and mixing it with private stock is a fast way to get a recoupment letter. Then add parents who divorce and split coverage, and newborns who show up before the insurer has issued a member ID.
Outsourcing makes sense when small denials are being written off instead of worked, when nobody owns vaccine reconciliation, or when your one billing person is also covering the front desk. A pediatric biller knows which plans pay screening codes at all and chases newborn enrollment until it clears. A generalist will not, and you will find out from your own aging report. On the form, give your provider count, a rough Medicaid share, whether you give vaccines in house, and which practice software you run. Then read the proposals for how they treat the add-on codes and the vaccine shelf. Anyone who skips those two is pricing a different practice than yours.
