Days in AR from 73 to 42. $1.7M of aged dental AR recovered.
A pediatric-heavy dental service organization was carrying $2.7M of over-90-day AR across three Medicaid dental carve-out models. CDT edit layer installed, carve-out routing corrected, 39 enrollment gaps closed, every EOB reconciled to the ledger, and $317K of recoupment demands overturned.
Result snapshotThe four numbers that moved.
The aging melt curve9 months. $6.8M to $3.9M.
Resolution of the $2.7M over-90 pool: $1.7M collected, $0.6M documented and written off as validated uncollectable, $0.4M still in active follow-up at month 9. The three figures tie to the pool exactly.
The situationThree defects. One aging report. Nobody owned the routing.
Frequency limits and missing tooth detail.
Claims sent to the wrong payer entity.
Providers billing from unenrolled locations.
The structural context matters. Dental services are a mandatory Medicaid benefit for enrollees under 21 through EPSDT, and more than 37 million children are enrolled in Medicaid and CHIP nationally, so a pediatric-heavy DSO lives or dies on how well it runs the Medicaid dental rail. In the mid-Atlantic that rail is fragmented: Maryland administers dental through the Healthy Smiles Dental Program with a single statewide administrator, Virginia runs Smiles For Children through one dental benefits administrator under DMAS, and other states delegate dental to plan-contracted dental benefit managers. Each model has its own payer ID, portal, filing clock, and audit unit.
The fix · payer routingOne routing gate. Three carve-out models. Zero guesswork.
At baseline, 11 percent of Medicaid dental claims were going to the wrong entity, mostly claims billed to the medical MCO when the dental benefit sat with a carve-out administrator. Those claims did not deny cleanly. They pended, aged past the carve-out's own filing clock, and died quietly. Re-routing and refiling the salvageable inventory recovered $348K.
EOB-to-ledger reconciliationEvery 835 and paper EOB. Matched to the ledger line.
KPI movement before vs current.
CDT denial taxonomyWhere the denied dollars actually sat.
CDT is maintained by the American Dental Association and a new version takes effect every January 1, so the edit layer is rebuilt annually against the new code set and each state program's coverage updates.
Per-location credentialing178 enrollment records. 39 gaps closed. $486K released.
Under 42 CFR 455.410 every rendering provider must be screened and enrolled with the state Medicaid program, and the enrollment is validated against the service location on the claim. The grid below shows enrollment records in good standing per location, baseline in red, after the 120-day closure sprint in green.
Recoupment defense$412K demanded. $317K kept.
States are required to operate Medicaid Recovery Audit Contractor programs under section 6411 of the Affordable Care Act, and dental benefit managers layer their own post-pay utilization audits on top. During the engagement the DSO received two post-pay audit demands totaling $412K, centered on radiograph frequency and stainless steel crown documentation.
The defense file for every audited line: the radiograph or clinical note, the CDT descriptor in force on the date of service, the EOB proving what was actually paid, and the ledger line proving what was posted. Lines the record could not support were conceded early, which bought credibility on the lines that mattered.
We thought our problem was slow payers. It was our own routing, our own enrollment gaps, and claims we never reconciled after posting. Once every claim knew where it was supposed to go and who was allowed to bill it, the aging report fixed itself.
