How to Fill Out and Submit the CMS 95 Illinois Physician’s Statement

The CMS 95 Illinois Physician’s Statement is the medical certification form state employees use to request a disability leave of absence or to get cleared for a return to work. You fill in the short authorization section at the top, your physician completes eight clinical sections describing your diagnosis and limitations, and you return the signed form to your agency’s personnel office within the deadline your agency sets. Missing that deadline can end your leave.

When the Form Is Required

The most common trigger is a disability leave of absence. Under Illinois administrative rules, a state employee who cannot perform a substantial portion of regular duties because of a temporary physical or mental disability may request leave for the duration of the disability, and the agency can require written medical verification of the diagnosis, prognosis, and expected length. The CMS 95 is the standard vehicle for that verification.¹

You also need one when sick leave stretches beyond ten consecutive workdays. At that point, the code requires medical verification under the same disability-leave standards.¹ For absences of ten days or fewer, your agency can still ask for evidence if it suspects misuse, but the CMS 95 is not automatically required.

One rule catches people off guard: unless your disability is service-connected, you must use up your available sick leave before the agency will grant a disability leave. You can also use other accrued paid time if you want, but you are not forced to.¹

If you know a disability is coming, such as a scheduled surgery, the rules require you to notify your supervisor as soon as you become aware of it and to provide a written physician’s statement with the approximate date you will be unable to work.¹ Submitting the CMS 95 before the leave starts keeps your status clean from day one.

Where to Get the Form

The current CMS 95, form number IL 401-0784, is a downloadable PDF from the Illinois Department of Central Management Services website.² Print it and bring it to your appointment. Your agency’s personnel office may also stock blank copies. The full title, “Physician’s Statement: Authorization for Disability Leave and Return to Work,” signals that the same form covers both going out on leave and coming back.

Your Part: The Employee Section

Fill in the top of the form before your appointment. That means your name, any employee identifiers your agency uses, and the authorization at the top that gives the state permission to review the medical information your doctor provides. Sign and date it. Doing this in advance saves your physician’s time and avoids a second trip if something is missed.

Your Physician’s Part: The Eight Clinical Sections

The bulk of the form is your physician’s to complete. Ask them to type or print clearly; illegible entries slow processing and can trigger a request to redo the form. Each numbered section asks for specific information.²

Section 1, Diagnosis: the date of your most recent examination, the diagnosis with any complications, your subjective symptoms, and objective findings from lab work, X-rays, EKGs, or clinical examination.
Section 2, Dates of Treatment: the date of your first visit, the date of your most recent visit, and how often you are being seen.
Section 3, Treatment: any surgery or medication prescribed, and whether the treatment will substantially improve your ability to function and work.
Section 4, Progress: whether you have recovered, improved, remained unchanged, or worsened, along with whether you are ambulatory, confined to your home, or confined to bed, and whether you have been hospitalized for the condition.
Section 5, Limitations: specific functional restrictions checked from a list covering standing, climbing, bending, use of hands, stooping, lifting, psychological limitations, or other restrictions the physician specifies.
Section 6, Physical Impairment: a classification rating from Class 1 (no limitation, capable of heavy work) through Class 5 (severe limitation, incapable of even sedentary activity). The classes map to impairment percentages and are based on the Federal Dictionary of Occupational Titles.
Section 7, Extent of Disability: whether you are temporarily totally disabled from any occupation or only from your regular occupation, the approximate date you can return to work, and whether you are permanently and totally disabled.
Section 8, Remarks: space for anything that does not fit the other sections.

After the last section, your physician signs the form, prints their name, lists their degree, and provides their office address and phone number.

What Slows Processing Down

The most frequent problem is vague or missing information in Sections 5 through 7. Your agency needs to know exactly what you cannot do. “Patient has limitations” is not enough. A concrete restriction, such as no lifting over ten pounds or no standing longer than twenty minutes, gives the reviewer a basis to decide. Leaving the return-to-work date blank in Section 7 also stalls approval because there is no timeline to work against.

The other recurring issue is a mismatch between the diagnosis in Section 1 and the limitations in Sections 5 and 6. If the clinical story doesn’t hang together, say a carpal tunnel diagnosis paired with a restriction on climbing stairs, expect the form to come back for clarification.

Submitting the Form

The form instructs you to return it “to the appropriate person within your agency within the time limits established by your agency.”² That person is usually someone in your agency’s personnel office or human resources department. Each agency sets its own deadline, so call your personnel office before the appointment to confirm the number of days you have and who receives the completed form.

Faxing is the fastest option and the one most agencies prefer. Keep the fax confirmation sheet as proof of timely delivery. Some agencies accept hand-delivery or mailing, both slower and riskier. If your agency has a secure document upload portal, confirm in advance that it accepts the CMS 95.

The stakes are real. The form itself warns that failure to comply with submission requirements “may result in termination of your disability leave,”² and the administrative code says the same: failing to provide verification of continued disability on reasonable request will cause termination of the leave.¹

Updated Forms Every 30 Days

One CMS 95 does not cover an indefinite absence. During a disability leave, you must provide updated medical verification at least every 30 days, unless the nature of your disability makes that frequency unnecessary.¹ In practice, that means scheduling follow-up visits and submitting fresh forms on a rolling basis for the length of your leave. Put the dates on a calendar. Losing track of the 30-day cycle is one of the easiest ways to have leave terminated.

Using the Same Form to Return to Work

When your physician clears you to resume your duties, you submit another CMS 95 with Section 7 marked to show you are able to return, the return date filled in, and any remaining restrictions noted in Section 5.² Disability leave ends automatically once you are no longer temporarily disabled from performing your regular duties,¹ so submit the return-to-work form as soon as your physician clears you rather than waiting for the agency to reach out.

If the Request Is Denied

A denial usually means the medical information on the CMS 95 did not establish that your condition prevents you from performing a substantial portion of your regular duties. Ask your physician to provide more detailed or specific documentation and resubmit. Many denials come from incomplete forms rather than genuinely unsupported claims. Illinois state employees covered by a collective bargaining agreement can also file a grievance through their union if they believe a denial violates the terms of their contract or the personnel rules.³

If the agency doubts you are actually unable to work, or suspects you are ready to return before your physician says so, it can send you to an impartial physician for an independent evaluation, and that physician’s opinion controls.¹
