Understanding Workers Compensation Form 4906(g) and How to Complete It

What is Form 4906(g)?

Form 4906(g) is a state‑specific workers compensation worksheet used to document an employee's medical diagnosis, treatment plan, and estimated duration of disability after a workplace injury. It serves as the primary evidence for insurers and claims adjusters to determine wage‑replacement benefits and medical reimbursements.

When Is the Form Required?

The form must be filed whenever an injured worker receives a new or revised medical opinion that could affect the benefits calculation. Typical triggers include:

• Initial diagnosis after an injury
• Change in prognosis or treatment scope
• Return‑to‑work clearance with restrictions

Employers or their insurance carriers usually request the form from the treating physician within 30 days of the medical update.

Key Sections of the Form

Form 4906(g) is divided into four main blocks, each demanding precise data:

• Patient Information: name, employee ID, date of injury, and employer details.
• Medical Diagnosis: ICD‑10 code, description of the injury, and any comorbid conditions.
• Treatment Plan: prescribed therapies, surgeries, medication, and expected frequency.
• Disability Estimate: projected total disability weeks, partial‑time work allowances, and any required accommodations.

Step‑by‑Step Completion Guide

1. Gather Accurate Patient Data

Confirm the employee's legal name, social security number, and the exact date of the incident. Mistakes here can delay claim processing.

2. Record the Diagnosis Correctly

Use the official ICD‑10 code list to match the physician's diagnosis. Include both the code and the textual description to avoid ambiguity.

3. Detail the Treatment Plan

List each intervention chronologically, noting start dates, expected duration, and any follow‑up appointments. If multiple providers are involved, indicate the coordinating physician.

4. Estimate Disability Duration

Base the weeks of total disability on the physician's prognosis. If only a range is provided, choose the median value and note the range in a comment field.

5. Review and Sign

The treating doctor must sign and date the form. A digital signature is acceptable in most jurisdictions, provided it meets state authentication standards.

Common Pitfalls and How to Avoid Them

Even experienced clinicians miss details that cause claim rejections. Watch for these frequent errors:

• Leaving the ICD‑10 code blank or using an outdated version.
• Omitting the employer's workers compensation policy number.
• Providing vague treatment timelines (e.g., "ongoing" without an end date).
• Failing to indicate partial‑return‑to‑work restrictions.

Cross‑check each field against the original medical notes before submission.

Submitting the Form

After the physician signs, the completed 4906(g) should be uploaded to the employer's claims portal or mailed to the state workers compensation board, following the carrier's preferred method. Retain a copy for the employee's file; auditors often request the original during compliance reviews.

What Happens After Submission?

The insurer reviews the form alongside supporting medical records. If the information aligns with policy guidelines, benefits are approved and the employee receives wage‑replacement payments. Discrepancies trigger a request for clarification, which may delay payments by up to two weeks.
