Denial Management Services in Massachusetts for Healthcare Providers: MassHealth's 90-Day Clock and Final Deadline Appeals
MassHealth runs one of the tightest filing windows in the country. Under 130 CMR 450.309, an initial claim must reach MassHealth within 90 days of the date of service, or within 90 days of the other insurer's explanation of benefits when MassHealth is secondary. A claim that met that first deadline can be corrected and resubmitted as many times as needed, but only up to 12 months from the service date, or 18 months when other insurance was billed first.
When a claim is denied for passing that final deadline, it shows on the remittance with error code 853 or 855. The practice then has 30 days from that remittance to file with the MassHealth Final Deadline Appeals Board, and it must prove a MassHealth error caused the late denial. Claims more than 36 months past the service date are not eligible, so an unworked denial can become permanent quickly.

What Makes Our Massachusetts
Denial Management Services Different
Some Massachusetts practices hire us for denials alone; others pair it with our medical billing services.
MassHealth Deadline Tracking
Every MassHealth claim is logged against three dates: the 90-day initial window, the 12-month resubmission limit, and the 18-month limit when other insurance pays first. Claims near any of them move up the queue.
Final Deadline Appeals
When MassHealth denies with error code 853 or 855, the 30-day appeal clock starts at once. We file with the Final Deadline Appeals Board and document the MassHealth error the regulation requires.
Behavioral Health Take-Back Defense
Massachusetts limits retroactive behavioral health denials to 12 months from claim submission, with a written reason and time to submit records. We hold Blue Cross plans, HMOs, and MassHealth to those rules.
Late-Payment Interest Recovery
Massachusetts insurers must act on claims within 45 days or owe 1.5% interest per month, up to 18% a year. We flag claims that pass the limit and follow up when interest is missing.
Root Cause, Not Just Rework
Every denial is tagged to its source, whether registration, authorization, coding, or charge entry. Your team sees which fixes stop repeat denials instead of watching the same codes come back each month.
Monthly Denial Reporting
Each monthly report breaks denials down by payer, CARC code, and rendering provider, with dollars recovered and dollars still pending, so you can measure progress in plain numbers rather than guesswork.
Specialty Expertise That Works for You
Mediknocx supports practices in 75+ medical specialties, and each has its own denial pattern. Behavioral health and psychiatry practices face retroactive take-backs and authorization denials, while primary care and pediatrics see eligibility and coordination-of-benefits denials. Your denials go to billers who know your specialty's codes.
How Does Mediknocx Ensure Compliance
With Massachusetts Denial Management Regulations?
No Surprises Act:
On out-of-network emergency or in-network facility denials, we check federal cost-sharing limits before any balance shifts to the patient.
Massachusetts timely filing law:
MassHealth requires initial claims within 90 days of service, with a final deadline of 12 months (18 with other insurance). Commercial carriers must pay, deny, or request information within 45 days.
Massachusetts billing transparency and itemization:
Before a retroactive behavioral health denial, payers must give a written explanation and describe any documentation needed. Take-backs tied to other coverage require at least 15 days' notice. We use those notices to dispute each case.
Payer-specific guidelines:
We follow Blue Cross Blue Shield of Massachusetts appeal steps, each MassHealth managed care plan's dispute process, and MassHealth's 90-day waiver and Final Deadline Appeals rules.
