Unum CL-1018 Critical Illness & Cancer Claim Form

Unum uses this claim form for voluntary benefits and group critical illness or specified disease coverage and for voluntary benefits and group cancer coverage, and one form covers a patient insured under several of them. The attending physician confirms the diagnosis, its date and the evidence for it, such as a pathology or surgical report. The benefit is a lump sum paid directly to the insured.

Who completes it

The physician or treating provider primarily responsible for the patient's care completes the Attending Physician Statement on pages 8 and 9. The insured completes the Insured/Patient Statement on pages 4 to 6 and signs the authorization on the last page.

How to fill it in

Attending Physician Statement (Please Print): instructions and identification

Unum asks you to complete all applicable questions, provide copies of supporting reports such as office notes, medical records, consultations or testing, and sign and date the form. Enter the insured's name and Social Security number, then the patient's, since the patient can be the insured, a spouse, a domestic partner or a child. Add the patient's relationship to the insured, gender and date of birth.

Diagnosis Information

This part is completed for all medical conditions. Enter the diagnosis with its ICD code, the date of diagnosis and the date you were first consulted for the condition. Directly below, the form asks you to check each condition that applies and provide the test results, operative reports, pathology reports or detailed medical statement required for it.

Condition, Medical Documentation and Other Pertinent Information

Check each condition that applies and supply the documentation listed beside it. Cancer and carcinoma in situ need a pathology report or clinical diagnosis, and cancer also asks for stage and grade. Blindness needs corrected visual acuity and visual field restriction for each eye. Coma asks about 14 or more consecutive days of unconsciousness and intubation, end stage renal failure about dialysis, and major organ failure about the UNOS list and date added.

Return to Work Assessment

Answer whether you advised the patient to stop work and when, and whether you have advised a return to work, with the expected date and full-time or part-time status. If the patient is returning, list ongoing restrictions and limitations on the next page; if not, list the restrictions and limitations that prevent the return.

Current Restrictions and Current Limitations

At the top of page 9, repeat the insured's and patient's names and dates of birth. Then describe current restrictions (activities the patient should not do) and current limitations (activities the patient cannot do). The form asks you to be specific in both boxes, which follow from your answers in the Return to Work Assessment.

Hospitalizations and Other Treating Providers

Answer whether another physician has treated the patient for the same or a similar condition, and list other treating physicians or hospitals with specialty, address, phone, fax and treatment dates. Give any hospital stay with dates and facility, any surgery with CPT-4 codes and date, and whether the patient is still under your care or the final date of treatment.

Signature of Attending Physician

Read the fraud notice, which applies to the Attending Physician portions of the claim form. Print your name, medical specialty, degree, address, telephone and fax numbers and Tax ID number, answer whether you are related to the patient, and sign and date to confirm the statements are true and complete.

Common mistakes

  • Checking a condition without attaching the documentation listed beside it, such as the pathology report for cancer or neuroimaging or documented deficits for stroke.
  • Leaving cancer stage and grade blank, or the corrected visual acuity and visual field restriction blank for blindness, when those conditions are checked.
  • Omitting the date of diagnosis or the date you were first consulted, which the Diagnosis Information block asks for on every claim.
  • Answering the return-to-work questions without describing the current restrictions and limitations on page 9, which the form asks for whether or not the patient is returning.
  • Leaving the insured's and patient's names and dates of birth off page 9; Unum asks for them on every page in case pages become separated.
  • Submitting incomplete or illegible answers, which Unum's instructions warn may delay benefit consideration.

Submitting and payment

How to submit it
Unum's instructions ask the physician to fax the completed statement to Unum or mail it to the address printed on the form. The insured can also file the claim through Unum's portal or app, or by phone.
Who pays
The instructions state that Unum is not responsible for expenses associated with completing the Attending Physician Statement.

Good to know

  • A claim for the Health Screening/Wellness Benefit alone does not need the Attending Physician Statement; the insured completes only sections A, B, C and G of their statement.
  • For cancer benefits, the insured attaches itemized bills showing ICD diagnosis codes, CPT-4 procedure codes and treatment dates, plus a copy of the pathology report.
  • Its pages are headed both 'Cancer Claim Form' and 'Critical Illness/Specified Disease Claim Form'. It is a 10-page fillable PDF, revision 05/26.
  • Unum points claimants to the policy for the complete definitions of covered conditions and notes that exclusions and limitations may affect the benefits payable.

Critical Illness/Specified Disease Claim Form

How this list is checked

A form is listed only after its name and number were confirmed on the issuing agency’s or insurer’s own website, or in the form itself. Each entry links to that source. The list was last checked in October 2026. Forms and their requirements change without notice, so check the official page for the current version before you complete one.

Frequently asked questions

What proof does Unum need from the doctor for a critical illness claim?

It depends on the condition checked. The statement lists the documentation for each: a pathology report or clinical diagnosis for cancer, a tissue biopsy for a benign brain tumor, EKG, cardiac enzymes, thallium or MUGA scans or stress echocardiogram for a heart attack, documented neurological deficits or neuroimaging for stroke, and a surgical report for coronary artery bypass or major organ transplant.

Does Unum CL-1018 cover group critical illness claims?

Yes. The instructions list four claim types: voluntary benefits critical illness or specified disease, voluntary benefits cancer, group critical illness or specified disease, and group cancer. A person covered by more than one of these products completes only this one form.

Who pays for completing Unum's critical illness physician statement?

Not Unum. The form's instructions state that Unum is not responsible for expenses associated with completing the Attending Physician Statement. The critical illness or cancer benefit itself is a lump sum paid to the insured, and a claim for the health screening benefit alone does not need the physician statement at all.

Which conditions are listed on Unum's critical illness claim form?

The checklist includes benign brain tumor, blindness, cancer, carcinoma in situ, cerebral palsy, cleft lip or palate, coma, coronary artery bypass surgery, cystic fibrosis, Down syndrome, end stage renal failure, heart attack, major organ transplant or failure, occupational HIV, permanent paralysis, spina bifida and stroke. Which ones a patient's policy covers depends on the plan.
