Massachusetts Timely Filing for Therapists: 4 Easy Clocks
Massachusetts timely filing for therapists is the deadline by which a payer must receive your claim, and it differs by payer. MassHealth publishes its clocks; commercial plans set theirs in your contract. A claim that arrives late can be denied for good, so the clocks matter more than most coding questions.
Massachusetts timely filing for therapists starts with the payer
There is no single Massachusetts deadline for every payer. Medicare, MassHealth and each commercial plan keep their own. Write the deadline for each payer next to its name in your billing system, and tell your biller where the number came from. The sections below separate the three.
Medicare and Medicaid: the MassHealth clocks
MassHealth lays out its deadlines on its billing timelines and appeal procedures page (updated May 1, 2024). The rule itself is in 130 CMR 450.314, which Cornell’s Legal Information Institute publishes online. It says MassHealth will not pay a claim for services provided more than 12 months before it is submitted or resubmitted, subject to exceptions in other sections.
| Clock | What it means | If you miss it |
|---|---|---|
| 90 days | MassHealth must receive the initial claim within 90 days of the date of service. If another insurer must pay first, the 90 days run from that insurer’s explanation of benefits date. | Request a 90-day waiver; the page links a request form |
| 12 months | Final deadline for a claim first submitted within 90 days | Denial with error code 853 or 855 (final deadline exceeded) |
| 18 months | Final deadline when another insurer was billed first and the claim reached MassHealth within 90 days of that explanation of benefits date | Same 853 or 855 denial |
| 36 months | Claims received more than 36 months after the date of service are denied | Error 856 or 857; these cannot be appealed |
If a claim denies for 853 or 855 because of a MassHealth error, you can appeal. The page says to file within 30 days of the remittance advice date on which the claim first denied, to show the denial resulted from a MassHealth error and the claim could not otherwise be resubmitted on time, and to submit electronically through Direct Data Entry unless you hold an approved electronic claim submission waiver. Read the page for the full steps before you appeal.
Medicare is separate. Medicare.gov says a claim must be filed no later than 12 months after the service date, and that under Original Medicare the law requires the provider to file the claim.
Private payers: where the filing deadline lives
Massachusetts timely filing for therapists works differently with commercial plans, because the number lives in the contract.
Commercial plans set their own filing windows in the provider agreement and the provider manual, so do not assume one number applies to all of them. Pull each contract and each manual, copy the number and the date you checked it. Our guide to payer contract compliance shows where these terms usually hide. Blue Cross Blue Shield of Massachusetts and Point32Health each publish provider resources; use the plan’s own pages, not a general chart.
State rules for Massachusetts timely filing for therapists
For Massachusetts timely filing for therapists, the state rule that matters most for Medicaid is 130 CMR 450.314. For commercial plans, the contract controls. If a plan’s deadline is shorter than you expected, ask whether the contract lets you submit corrected claims or appeals outside the original window. Keep counsel in the loop on any dispute over a missed deadline.
How to track Massachusetts timely filing for therapists
Late claims often trace back to claims that were never sent, or that were rejected and never fixed. Build a short routine for Massachusetts timely filing for therapists:
- Work the rejection report first and resend fixed claims quickly, because a corrected claim still has to arrive inside the payer’s window.
- Check your clean claim rate weekly so errors do not pile up.
- List every claim with no payment and no denial, oldest first, using the monthly paysheet report or your own aging report.
- Read each remittance with the electronic remittance advice (ERA) guide and the claim adjustment reason code guide, so a denial reason is never guessed.
- If a payer paid less than the contract, see our guide to underpayments; the dispute window can be short.
What is the timely filing limit for therapy claims in Massachusetts?
For MassHealth, the initial claim must reach MassHealth within 90 days of the date of service, with a 12-month final deadline for claims first submitted on time. For Medicare it is 12 months. For commercial plans, the limit is in your contract. That is the full answer to Massachusetts timely filing for therapists, and the first job is knowing which payer owns the claim.
What to do Monday morning
- For Massachusetts timely filing for therapists, make a one-page list of payers with filing deadline, source and date checked.
- Find every MassHealth claim older than 60 days that is unpaid.
- Resubmit or appeal what you can before the clock runs out.
- Set a weekly reminder to review rejections and the oldest unpaid claims.
The short version: Massachusetts timely filing for therapists
Massachusetts timely filing for therapists means knowing the deadline for every payer you bill. MassHealth is 90 days to start and 12 months at the outside, Medicare is 12 months, and commercial plans follow their contracts. Track the oldest claims every week.
