What this form asks for

The AI fills all of it, from your answers or your documents.

Massachusetts DIA Form 110, “Employee’s Claim,” is the official Department of Industrial Accidents form used to initiate a disputed workers’ compensation claim for benefits related to a workplace injury, occupational exposure, or death. It captures identifying information for the employee, employer, and insurer, details about the injury and incapacity dates, wage information, medical treatment details, and the specific statutory benefits being claimed (e.g., M.G.L. c. 152 §§ 34, 35, 36, 31, 33, 13 & 30). Filing it correctly is important because it formally starts the DIA dispute process and helps ensure the claim is processed with the required documentation and signatures. Today, this form can be filled out quickly and accurately using AI-powered services like Instafill.ai, which can also convert non-fillable PDF versions into interactive fillable forms.

The AI checks your answers before you download

16 checks built for this form, so a wrong date or a missing answer is caught before anyone else sees it.

Employee Name completeness and character validation

Validates that the Employee’s Name includes at minimum a last name and first name, and that the middle initial (if provided) is a single alphabetic character. The check also rejects obviously invalid entries (e.g., all numbers, placeholder text like “N/A”, or excessive punctuation). This is important for identity matching and claim indexing; if it fails, the submission should be rejected or routed for manual review with a request for correction.

Social Security Number (SSN) format and plausibility check

Ensures the SSN is either blank (since disclosure is voluntary) or matches a valid SSN pattern (###-##-#### or #########), and is not an invalid sequence (e.g., 000-00-0000, 111-11-1111). This reduces misidentification and downstream matching errors with insurer/employer records. If validation fails, the system should flag the SSN field and require correction or allow submission only if SSN is omitted entirely.

Date fields format validation (mm/dd/yyyy) across the form

Checks that all date fields (Date of Birth, Date of Injury, First/Fifth Day of Incapacity, Date of Death, signature dates, and benefit period dates) are valid calendar dates in mm/dd/yyyy format. It should reject impossible dates (e.g., 02/30/2025) and non-date text. If this fails, the form should not be accepted because date-driven eligibility and timelines cannot be computed reliably.

Chronological consistency: Date of Birth vs. injury/incapacity/signature dates

Validates that Date of Birth occurs before Date of Injury, incapacity dates, and signature dates, and that the employee is not implausibly young/old (e.g., DOB after injury date). This prevents data entry mistakes that can invalidate the claim timeline and identity verification. If the check fails, the system should block submission and prompt the filer to correct the conflicting dates.

Injury and incapacity timeline logic (injury date, first day, fifth day)

Ensures the First Day of Total/Partial Incapacity is on or after the Date of Injury (or, if business rules allow, not unreasonably before it), and that the Fifth Day of Incapacity is on or after the First Day of Incapacity. This is critical for benefit calculations and statutory thresholds tied to incapacity duration. If validation fails, the system should require correction and highlight the specific inconsistent fields.

Death-related conditional requirements and date logic

If Date of Death is provided, validates it is on or after the Date of Injury and not in the future, and triggers additional consistency checks (e.g., survivor/burial benefits likely applicable). If Date of Death is blank, the system should not require death-related benefit selections. If this validation fails, the submission should be flagged for correction because death status materially changes claim handling.

And 10 more checks
  • Home address completeness and Massachusetts ZIP/State format
  • Phone number format validation (employee and attorney/carrier)
  • Email address format and conditional requirement for attorney email
  • Attorney information consistency (BBO#, contact fields, and signatures)
  • Employer and insurer/carrier identification completeness
  • Industry Code validation against allowed code list
  • Native Language Code validation against allowed values
  • Injury/Body Part code pair validation and allowed ranges
  • Average Weekly Wage numeric validation and Actual/Estimated selection rule
  • Insurer payments conditional details requirement

Common Mistakes in Completing MA DIA Form 110

The ones the AI is built to catch.

Using Form 110 for the wrong type of claimant
People often file Form 110 without noticing it is specifically for employees or dependents claiming benefits due to injury or death, and that “all other claimants should use Form 115.” Using the wrong form can lead to the DIA returning the submission or delaying the start of the dispute process. Before completing anything, confirm you are the correct claimant type for Form 110 and switch to Form 115 if you are not. AI-powered tools like Instafill.ai can help route you to the correct form and prevent filing the wrong document.
Illegible or incomplete identity/contact information
This form warns that unreadable forms will be returned, and many submissions fail due to hard-to-read handwriting or missing basics like full legal name, complete address, phone number, or date of birth. Missing or unclear contact details can prevent the DIA/insurer from matching your claim to existing records and from contacting you for scheduling or documentation requests. Print clearly or type, and double-check that every identity field is complete and consistent with your official records. Instafill.ai can auto-format names, addresses, and phone numbers and flag missing required fields before you submit.
Incorrect date formatting or inconsistent injury/incapacity dates
Applicants frequently enter dates in the wrong format (the form requires mm/dd/yyyy) or provide a “first day of incapacity” that doesn’t align logically with the date of injury. Inconsistent timelines can create disputes about eligibility, waiting periods, and benefit start dates, which can slow the claim or trigger requests for clarification. Use mm/dd/yyyy everywhere and verify the sequence: date of injury, first day of incapacity, and fifth day of incapacity should be coherent. Instafill.ai can validate date formats and flag timeline inconsistencies automatically.
Listing the local agent/administrator instead of the actual insurance carrier
Field 11 explicitly says “NOT LOCAL AGENT/ADMINISTRATOR,” but many people still enter the employer’s broker, TPA, or a local office rather than the workers’ compensation insurance carrier’s correct address and phone. This can cause misdelivery of notices, delays in service, and problems proving proper notice to the right party. Ask the employer for the official carrier information (as required by law) and copy the carrier’s full mailing address and phone number exactly. Instafill.ai can help standardize insurer details and reduce the chance of entering the wrong entity.
Leaving code fields blank or entering non-code text (industry, injury, body part, language)
The form relies on specific numeric codes (industry code, injury code(s), body part code(s), and native language code), but people often write descriptions instead of codes or leave them empty. Missing/incorrect codes can slow processing, lead to data entry errors, or cause the DIA to request corrections. Use the reverse-side code lists and enter the numeric code(s) that best match the situation, adding multiple codes only when appropriate. Instafill.ai can suggest and validate code entries and ensure they match the required numeric format.
Vague injury narrative that doesn’t match the coded entries
Many claimants write a very general description (e.g., “hurt my back”) without explaining how it happened, what body parts were involved, and what the medical diagnosis/condition is, or they provide narratives that conflict with the injury/body-part codes selected. Vague or inconsistent descriptions can weaken the claim, invite disputes, and trigger follow-up requests for more detail. Provide a concise but specific account: mechanism of injury/exposure, date/time context, and clearly identified body parts and symptoms/diagnosis. Instafill.ai can prompt for missing narrative elements and cross-check that the narrative aligns with selected codes.
Average weekly wage entered without selecting Actual vs. Estimated (or using the wrong basis)
People often fill in a wage number but forget to check whether it is “Actual” or “Estimated,” or they enter a guess that doesn’t reflect average weekly wage rules (e.g., using hourly rate only, or a single week’s pay). Wage errors can lead to incorrect benefit calculations and later disputes or overpayment/underpayment corrections. Use pay stubs or payroll records to compute the average weekly wage and clearly mark whether the figure is actual or estimated. Instafill.ai can help format currency correctly and remind you to select the appropriate wage type.
Returned-to-work and insurer-payment questions answered inconsistently or left incomplete
Checkbox questions like “Has Employee Returned to Work?” and “Has the Insurer Made Any Payments?” are frequently left blank, or “Yes” is checked without providing the required follow-up details (types of benefits and amounts). Incomplete answers can create confusion about current disability status and what benefits are already in play, delaying conference/hearing preparation. Always select Yes/No and, if Yes, provide the requested details (benefit type, dates if known, and total amount paid). Instafill.ai can enforce conditional logic so follow-up fields are completed when “Yes” is selected.
Benefits claimed (Sections of law) checked without dates, amounts, or required documentation
Claimants often check Section 34/35/36/medical/survivor benefits but leave the “from/to” date ranges blank, omit the Section 36 amount, or fail to attach documentation required by M.G.L. c. 152 §7G and 452 CMR 1.07. Missing dates and documentation can result in the claim being considered incomplete, returned, or delayed while the DIA requests supporting materials. Only check benefits you are actually claiming, complete all associated date ranges/amounts, and attach the required medical and wage documentation. Instafill.ai can prompt for missing attachments and ensure each selected benefit has its required supporting details.
Attorney section errors (required attorney email, missing BBO#, or filling attorney fields when pro se)
People sometimes partially complete the attorney section (e.g., provide a name but no BBO#) or miss that the attorney email is marked “Required” when an attorney is involved; others fill attorney fields even though they are self-represented. These mistakes can cause communication failures, misrouting of notices, or requests for correction. If you have an attorney, complete all attorney fields including BBO# and the required email; if you do not, leave the attorney section blank as instructed. Instafill.ai can detect whether attorney representation is indicated and ensure the correct attorney fields are completed (or left blank).
Missing signatures/dates or improper service/copy distribution
A very common rejection reason is failing to sign and date in Boxes 26 and 27 (the instructions state the employee must sign and date in all cases), or forgetting that the original must be mailed to the DIA and copies provided to the employer and insurer (and certified mail to the insurer when represented by counsel). Missing signatures invalidate the filing, and improper service can delay proceedings or create disputes about notice. Always sign and date the employee/claimant signature line, and follow the mailing/copy requirements exactly, keeping a copy for your records. If the form is only available as a flat non-fillable PDF in practice, Instafill.ai can convert it into a fillable version and help ensure signature/date fields and service steps aren’t missed.

What is Massachusetts DIA Form 110 (Employee’s Claim) used for?
Form 110 is used by an employee (or eligible dependents) to file a disputed workers’ compensation claim with the Massachusetts Department of Industrial Accidents (DIA). It is typically filed when the workers’ compensation insurer has denied the claim or is disputing benefits you believe you are owed.
Who should use Form 110, and who should use Form 115 instead?
Form 110 is for employees or dependents claiming benefits due to an injury or death. The form states that all other claimants should use Form 115.
Do I need an attorney to file Form 110?
No—representation by an attorney is not required, and you may file “pro se” (self-represented). You can still hire an attorney later if you choose.
Where do I send Form 110 after I complete it?
Mail the original to the DIA at the address on the form (Lafayette City Center, 2 Avenue de Lafayette, Boston, MA 02111-1750). You must also provide a copy to your employer and a copy to the insurer, and keep a third copy for your records.
Do I need to send the form by certified mail?
If you are represented by an attorney, the form must be sent to the insurer via certified mail. If you are not represented, the form instructions still require that the insurer and employer receive copies, but certified mail is specifically required when counsel is involved.
What documentation do I need to attach to Form 110?
The form instructions state that claims must be accompanied by proper documentation under M.G.L. c. 152, §7G and 452 CMR 1.07. Attach the documentation required for the benefit sections you check (for example, medical records/bills for medical expenses or proof supporting incapacity periods).
Is providing my Social Security Number required?
No—disclosure of your Social Security Number is voluntary. However, the form notes it will aid in processing your claim.
How do I fill out the “Date of Injury” and the “First/Fifth day of incapacity” fields?
Enter the date the injury occurred in the “Date of Injury” field. Then list the first day you were totally or partially unable to earn wages and the fifth day of that incapacity (all in mm/dd/yyyy format).
What if the employee died—can dependents still file, and what should be completed?
Yes, dependents may file Form 110 for benefits resulting from a work-related death. Complete the “Date of Death” field and check the appropriate benefits claimed (such as Survivor’s Benefits under Sec. 31 and Burial Expenses under Sec. 33), with required documentation.
How do I choose the correct Industry Code, Injury Code, and Body Part Code?
Use the code lists provided on the reverse side of the form: select the employer’s Industry Code, the Nature of Injury/Illness code(s), and the Body Part Affected code(s) that best match the situation. If multiple injuries/body parts apply, you can list up to three sets (a, b, c).
What should I put for “Average Weekly Wage” if I’m not sure of the exact amount?
Enter your best estimate and check the “Estimated” box if you do not have the exact figure. If you know the exact amount, enter it and check “Actual.”
What does “Has the insurer made any payments on your claim?” mean, and what should I include?
This asks whether the insurer has paid anything related to your claim (such as medical bills or wage replacement). If yes, check “Yes” and list the type of benefits and the amounts paid, including the total amount if known.
Which benefit boxes should I check in Section 23 (Sections of Law Claimed)?
Check all benefits you are claiming, such as Sec. 34 (total temporary incapacity), Sec. 35 (partial incapacity), Sec. 36 (specific compensation), Sec. 31 (survivor’s), Sec. 33 (burial), and Secs. 13 & 30 (medical). For Sec. 34 and Sec. 35, include the date ranges for the periods you are claiming.
What happens if I leave fields blank or the form is hard to read?
The form warns that unreadable forms will be returned, so print legibly or type. If a field does not apply (for example, attorney information when you have no attorney), leave it blank as instructed.
Can AI help me fill out Massachusetts DIA Form 110, and how would I do it with Instafill.ai?
Yes—AI tools can help reduce errors and save time by auto-filling form fields from the information you provide; services like Instafill.ai can do this accurately. Typically, you upload the Form 110 PDF to Instafill.ai, answer a guided set of questions (injury details, employer/insurer info, dates, benefits claimed), and the system populates the correct fields for you to review before downloading and signing.
What if my Form 110 PDF is not fillable (a flat/scanned PDF)?
If the PDF is not fillable, you can still complete it by printing and handwriting, but that increases the risk of legibility issues. Instafill.ai can convert flat, non-fillable PDFs into interactive fillable forms so you can type directly into the fields and generate a clean, readable submission.
