Frequently Asked Questions About WH-380-E
WH-380-E has a Form Complexity Index of 51 out of 100, placing it in the moderate complexity tier. This score is calculated deterministically from the form’s own structure using Instafill’s published Form Complexity Index methodology, so it can be reproduced and independently verified — it is not a subjective estimate.
For WH-380-E specifically, the score reflects 78 fillable fields across 4 pages, grouped into 15 sections, and 13 conditional fields that only apply depending on earlier answers. The number of fields is the largest factor in the base score (weighted 36%), followed by how difficult those fields are to complete based on their type, where free-text and signature fields count for more than simple checkboxes (26%). The number of pages that actually contain fields (15%), the amount of conditional “fill-only-if” logic (16%), and how many sections the form is divided into (7%) account for the rest of the base. On top of that base, the index adds points for tables and repeating lists, bundled instruction pages, and dense page layouts — capturing difficulty the base alone can miss.
In practical terms, a moderate score means the form takes real effort: there are enough fields, pages and rules that errors are easy to make by hand. Instafill removes that effort entirely: our AI reads your information, maps each value to the correct field — including the conditional ones — and completes WH-380-E accurately in under a minute, with every field available for you to review before you download. See exactly how the Form Complexity Index is calculated.
This form is used to obtain a medical certification from a health care provider to support an employee's request for leave under the Family and Medical Leave Act (FMLA) due to their own serious health condition.
You or your employer can fill out Section I, but Section II must be completed and signed by your health care provider. You are responsible for ensuring the completed form is returned to your employer.
Your health care provider should return the completed form to you. You must then submit it to your employer, not to the Department of Labor.
Your employer must give you at least 15 calendar days to return the medical certification. The specific due date should be listed in Section I, question (3) of the form.
If you fail to provide a complete and sufficient medical certification, your employer may deny your FMLA leave request. It is important to review the form with your provider to ensure all necessary questions are answered.
Either the employee or the employer may complete Section I. This section captures basic information about the employee, the employer, and the job.
Your doctor needs to provide medical facts about your condition, including the start date, expected duration, and whether it requires inpatient care or causes incapacity. They must also estimate the amount and frequency of leave needed in Part B.
If a job description is not provided, your health care provider can complete Part C based on your own description of your essential job functions.
In Part B, question (9), your doctor can provide their best estimate of how often (frequency) and for how long (duration) you will need to be absent from work for episodes related to your condition.
Yes, employers are required by law to maintain records and documents related to medical certifications as confidential medical records, separate from usual personnel files.

Compliance WH-380-E
Validation Checks by Instafill.ai
1
Validate Certification Return Deadline
This check ensures the 'Medical Certification Return By Date' is at least 15 calendar days after the 'Certification Request Date'. This is a legal requirement under FMLA, giving the employee adequate time to obtain the certification. If the return date is less than 15 days from the request date, the form is non-compliant and the request may be considered invalid until corrected.
2
Ensure All Dates are in Valid MM/DD/YYYY Format
This validation verifies that all date fields throughout the form (e.g., Request Date, Return By Date, Condition Start Date) are entered in a valid MM/DD/YYYY format and represent real calendar dates. This prevents data entry errors and ensures that calculations, such as the 15-day return window, are accurate. An invalid date format would cause the form submission to be rejected for correction.
3
Verify At Least One Medical Condition is Selected
This check confirms that in Part A, question 3, at least one of the checkboxes for a serious health condition (e.g., Inpatient Care, Pregnancy, Chronic Conditions) has been selected. The entire purpose of the form is to certify a serious health condition, so this section must be completed. If no condition is checked, or if 'None of the above' is selected, the certification is insufficient to support the FMLA leave request.
4
Conditional Requirement for Pregnancy Details
This validation ensures that if the 'Pregnancy' checkbox is selected in Part A, the 'Expected Delivery Date' field is also filled out with a valid, future date. This information is essential for planning the duration and timing of the leave. A failure in this check would render the certification incomplete, requiring the employee to have the provider add the missing information.
5
Incapacity Period Logical Date Check
For 'Incapacity plus Treatment' in Part A, this check validates that the 'End Date' is chronologically after the 'Start Date'. It also verifies that the duration between the two dates is greater than three consecutive calendar days, as required by the FMLA definition. An illogical date range would make the certification invalid for this category of serious health condition.
6
Validate Specificity of Intermittent Leave Estimates
This check scrutinizes Part B, question 9, regarding intermittent leave. It ensures that the frequency and duration fields are filled with specific numbers and units (e.g., '3 times per week', '8 hours per episode') and do not contain vague, non-actionable terms. Insufficient specificity prevents the employer from properly tracking FMLA leave, so a failure would require clarification from the health care provider.
7
Confirm Health Care Provider Signature and Date
This validation verifies the presence of a signature from the Health Care Provider and a corresponding signature date at the end of the form. The signature authenticates the medical information provided. An unsigned or undated form is legally insufficient and cannot be accepted as a valid medical certification.
8
Ensure Job Function Incapacity is Explained
This check ensures that if the provider indicates the employee is unable to perform essential job functions in Part C, the corresponding text box identifying at least one such function is filled out. This detail is critical for determining the employee's ability to work and for discussions about reasonable accommodations. A blank explanation field makes this section incomplete.
9
Health Care Provider Contact Information Format
This validation checks that the provider's telephone and fax numbers are in a valid numerical format and that the email address follows the standard '[email protected]' structure. Accurate contact information is crucial in case the employer needs to contact the provider for clarification or authentication of the certificate. An invalid format would flag the field for review and correction.
10
Employee Name Consistency Across Pages
This check verifies that the 'Employee Name' entered at the top of each page is consistent with the name provided in Section I. This ensures data integrity and confirms that all pages of the submitted document belong to the same employee's certification. A mismatch could indicate a scanning or assembly error, requiring manual review to ensure the document is complete and correct.
11
Conditional Requirement for Inpatient Care Dates
This validation rule ensures that if the 'Inpatient Care' checkbox is selected in Part A, the corresponding field for admission dates is filled with at least one valid date. This date is necessary to verify the FMLA-qualifying event. If the box is checked but the date is missing, the certification is incomplete and must be returned for correction.
12
Prohibit Vague Terminology in Duration Fields
This check scans key estimation fields, such as 'Condition Duration Estimate' (Part A, #2) and the narrative sections of Part B, for prohibited vague terms like 'unknown,' 'indeterminate,' or 'lifetime.' The form explicitly states these may not be sufficient. Using such terms prevents the employer from understanding the expected duration of leave, so their presence would flag the form as insufficient.
Common Mistakes in Completing WH-380-E
Health care providers often write 'unknown,' 'as needed,' or 'indeterminate' in Part B when asked for the frequency and duration of incapacity. This occurs because predicting an illness's course is difficult, but FMLA requires a 'best estimate.' Vague answers make it impossible for an employer to manage leave, leading to requests for clarification and delays in approval. To avoid this, providers should give a specific, qualified estimate (e.g., '1-2 episodes per month, lasting 1-3 days each'), as the certification can be updated if the condition changes.
In Part A, a provider might check a box like 'Incapacity plus Treatment' but then fail to fill in the corresponding start/end dates of incapacity or the dates of treatment. This renders the certification incomplete because the supporting details are missing. An employer cannot approve the leave without this specific information, which means the form will be returned to the employee for correction, delaying the entire process.
In Section I, employers sometimes leave the 'Essential Job Functions' field blank or provide only a vague job title, and they may forget to check the box indicating a job description is attached. This prevents the health care provider from making an informed judgment in Part C about whether the employee's condition impacts their ability to perform their duties. Without this context, the certification may be deemed insufficient, potentially leading to denial of leave.
A common error is when information in one part of the form contradicts another. For example, a provider might check 'Chronic Conditions' in Part A (implying intermittent leave) but then only fill out Part B's section for a single, continuous period of incapacity. This creates confusion for the employer and can result in the certification being rejected for insufficiency, requiring clarification and delaying the employee's FMLA approval.
A surprisingly frequent and critical mistake is the health care provider forgetting to sign and date the form on page 4. An unsigned or undated certification is invalid and will be immediately rejected by the employer. This forces the employee to make another trip to their doctor's office to get the signature, causing significant and stressful delays in the approval of their leave.
Since this form is often printed and filled out by hand, illegible handwriting from the health care provider is a major issue. If an employer cannot read the provider's name, contact information, or medical justifications, they cannot process the form and may need to request clarification. This can significantly delay the FMLA approval process. If the form is a non-fillable PDF, AI-powered tools like Instafill.ai can convert it into a fillable version, allowing for typed, legible responses.
In Section I, employers must give employees at least 15 calendar days to return the form. A common error is miscalculating this date by counting only business days or providing less than the required time. This can invalidate the deadline and weaken the employer's position if they later deny leave for an untimely certification. Employers must carefully count 15 full calendar days from the request date to set a valid, enforceable deadline.
The form consistently specifies the 'mm/dd/yyyy' format for all date fields, but users often enter dates in other formats (e.g., 'June 30, 2023'). This can lead to data entry errors on the employer's end or misinterpretation of the timeline, causing processing delays. Using the specified format consistently is crucial for a smooth process. AI-powered form filling tools like Instafill.ai can help prevent these errors by automatically validating and formatting data correctly.
The form explicitly states in bold, capital letters: 'DO NOT SEND COMPLETED FORM TO THE DEPARTMENT OF LABOR. RETURN TO THE PATIENT.' Despite this clear instruction, some individuals mistakenly mail the form to the government. This results in a significant delay, as the form will not be processed or returned, and the employee will miss their submission deadline with their employer. The completed form must always be returned to the employee for submission to their HR department.
In Part C, when asked to identify an essential job function the employee cannot perform, a provider might write something generic like 'cannot work' or 'lifting.' This is insufficient for the employer to understand the specific limitations and explore potential accommodations. The description should be specific, such as 'cannot lift items over 10 pounds,' to justify the need for leave and ensure the certification is complete.
