How to Choose the Right Form
Not all enrollment forms serve the same purpose — some are for Medicare coverage, others for health plan dependents, and one is for academic course tracking. Here's how to find the right one quickly.
Enrolling in Medicare Part B
If you're looking to sign up for Medicare Part B medical insurance, you have two options depending on your situation:
- Form CMS-4040 — Use this if you are enrolling in Medicare Part B for the first time or during a general enrollment period.
- Form CMS-40B — Use this if you already have Medicare Part A and need to add Part B, especially if you missed your initial enrollment window or qualify for a special enrollment period.
Medicare Provider Enrollment
If you're a physician or healthcare professional who needs to order or certify items and services for Medicare beneficiaries (rather than enrolling as a patient), use:
- Form CMS-855O — This Medicare Enrollment Application is specifically for ordering and certifying providers, not individual beneficiaries.
Adding Dependents to a Health Plan
If you're a Providence Health Plan subscriber and need to add a dependent who lives or receives care outside your plan's service area, use:
- Providence Health Plan Out-of-Area Dependent Enrollment Form — This covers dependent demographics, member IDs, and effective-date details for out-of-area coverage.
Academic & Training Course Registration
If you're an instructor or training coordinator who needs to document course logistics and student attendance for certification or compliance purposes, use:
- Course Roster and Location Registration Form — This captures venue details, course times, and a full student roster including names, emails, and phone numbers.
Quick tip: If you're an individual seeking health coverage, start with the Medicare forms. If you're managing a training session or adding a plan dependent, the last two forms are your go-to options.

Tips for enrollment forms
Many enrollment forms — especially Medicare Part B applications — have specific eligibility windows and special enrollment periods. Before filling out any form, confirm you meet the eligibility requirements to avoid delays or rejection. Submitting at the wrong time can result in gaps in coverage or late enrollment penalties.
Enrollment forms often require supporting information such as Medicare Part A card numbers, employer group details, dependent Social Security numbers, or proof of prior coverage. Having these documents on hand before you begin will prevent you from leaving fields blank or submitting incomplete forms. Incomplete submissions are one of the most common reasons for processing delays.
AI-powered tools like Instafill.ai can complete enrollment forms in under 30 seconds with high accuracy, saving you significant time — especially when dealing with multiple forms at once. Your data stays secure throughout the process, so you don't have to worry about privacy. This is a real time-saver for coordinators managing course rosters or HR staff adding multiple dependents.
When filling out enrollment forms, always enter names, member ID numbers, and Social Security numbers exactly as they appear on official records. Even minor discrepancies — like a middle initial or a hyphenated last name — can cause mismatches in processing systems. This is especially critical for Medicare enrollment and health plan dependent forms.
Many health plan and Medicare enrollment forms have rules governing when coverage actually begins, which may differ from the date you submit the form. Read the instructions carefully to understand how effective dates are calculated, and note any optional fields where you can request a specific start date. Submitting without this knowledge can lead to unexpected coverage gaps.
Always save or print a copy of any enrollment form you submit, along with any confirmation numbers or submission receipts. This is essential if a form gets lost, a dispute arises about coverage start dates, or you need to reference the information for a future update. For course rosters, retaining copies ensures you have a backup for certification and compliance audits.
Skipping optional fields or leaving sections partially filled is a common mistake that can slow down enrollment processing. Even fields that appear optional — like contact phone numbers on a course roster or an employer group number on a health plan form — may be required by the receiving organization. Take a final pass through the entire form before submitting to catch any oversights.
Frequently Asked Questions
This category includes five enrollment forms covering a range of needs: Medicare Part B enrollment (CMS-4040 and CMS-40B), Medicare provider enrollment for ordering and certifying professionals (CMS-855O), health plan dependent enrollment (Providence Health Plan Out-of-Area Dependent Enrollment Form), and course or training registration (Course Roster and Location Registration Form). Each form serves a distinct purpose, so it's important to identify which one matches your specific situation before filling it out.
If you are an individual looking to enroll in Medicare Part B coverage, you would typically use either Form CMS-4040 or Form CMS-40B — CMS-40B is specifically for those who already have Medicare Part A and missed their initial enrollment period or qualify for a special enrollment period. If you are a physician or healthcare professional who needs to order or certify items and services for Medicare beneficiaries, Form CMS-855O is the appropriate choice.
This form is intended for Providence Health Plan subscribers who want to add a dependent — such as a child or spouse — who lives outside the plan's primary service area or regularly receives care outside that area. Submitting this form ensures the dependent's coverage is set up correctly and that reimbursements are handled according to the plan's out-of-area rules.
This form should be completed whenever a course or training session is being organized and official records need to be maintained for certification, compliance, or attendance purposes. It captures key logistics like venue, course times, and participant contact information, making it essential for issuing participant cards and maintaining accurate training records.
Completed Medicare enrollment forms are generally submitted to your local Social Security Administration office (for individual enrollment forms like CMS-4040 and CMS-40B) or to the appropriate Medicare Administrative Contractor (for provider enrollment forms like CMS-855O). It is recommended to check the Centers for Medicare & Medicaid Services (CMS) website or contact your local office for the most current submission instructions.
Yes, Medicare enrollment is subject to specific enrollment periods — such as the Initial Enrollment Period, General Enrollment Period, and Special Enrollment Periods — and missing these windows can result in late enrollment penalties or gaps in coverage. The exact deadlines depend on your personal circumstances, so it's advisable to consult the CMS website or speak with a Medicare representative to confirm the applicable timeframes for your situation.
Most enrollment forms in this category require personal identification details such as full name, date of birth, and contact information, along with relevant account or membership numbers (e.g., Medicare ID or member ID). Provider-focused forms like CMS-855O may also require professional credentials and practice information, while training forms like the Course Roster require participant contact details and course logistics.
Yes, AI-powered tools like Instafill.ai can fill out enrollment forms in under 30 seconds by accurately extracting and placing data from your source documents. This significantly reduces manual data entry errors and speeds up the process, whether you're completing a Medicare application or a course registration form.

With AI-powered services like Instafill.ai, the process can be completed in under 30 seconds, as the tool automatically extracts and populates the required fields from your existing documents.
Some enrollment forms are distributed as non-fillable PDFs, which can make completing them digitally more difficult. AI-powered services like Instafill.ai can convert non-fillable PDF versions into interactive fillable forms, allowing you to complete and submit them online without needing to print and fill them out by hand.
Many enrollment forms require accompanying documentation — for example, Medicare enrollment forms may require proof of age, citizenship, or prior insurance coverage, while provider enrollment forms may require professional license information. Always review the specific instructions for the form you are completing to ensure you include all required attachments, as missing documents can delay processing.
The government-issued forms in this category — such as the CMS-4040, CMS-40B, and CMS-855O — are publicly available at no cost through the CMS website or Social Security Administration. The Providence Health Plan and Course Roster forms are typically provided by the respective organization or employer, and accessing them is generally free through the issuing entity.
