4.7 Workers' Compensation & Disability Claims
Key Takeaways
- Workers' compensation is administered state by state rather than federally, so fee schedules, filing deadlines, and forms differ by jurisdiction and the employer's state governs.
- Providers treating a work-related injury may never balance bill the injured worker; the state fee schedule amount is payment in full and there is no patient deductible, copayment, or coinsurance.
- Workers' compensation is not covered by the HIPAA authorization requirement in the same way as group health, because state law compels disclosure of injury-related records to the carrier and employer.
- A workers' compensation CMS-1500 changes several fields: Box 10a is marked yes, Box 11 carries the claim number, Box 14 carries the date of injury, and Box 16 carries the dates unable to work.
- Disability claims pay wage replacement rather than medical bills, so the provider's role is completing attending-physician statements and certifying functional limitations, not submitting a treatment claim.
4.7 Workers' Compensation & Disability Claims
The Detailed Test Plan lists "Complete and submit claims for Workers' Compensation or disability" as its own task. It sits apart from commercial and government plans because workers' compensation runs on an entirely different legal foundation, and because the rules that protect the injured worker are absolute in a way that no group health rule is.
1. What Workers' Compensation Is
Workers' compensation is a state-administered, no-fault insurance system. An employee injured in the course of employment receives medical care and partial wage replacement without proving employer negligence; in exchange, the employee generally gives up the right to sue the employer. The arrangement is often called the compensation bargain.
Three consequences follow directly, and all three are tested:
- There is no patient cost-sharing at all. No deductible, no copayment, no coinsurance.
- The employer or its carrier is the payer, not the patient's health plan. The patient's group health insurance is not billed for a work injury.
- The rules are the state's. Fee schedules, filing deadlines, forms, treatment guidelines, and even which physician the worker may see are set by state law.
Federal Programs That Sit Outside State Systems
A small set of workers are covered by federal programs rather than a state system: federal civilian employees under the Federal Employees' Compensation Act (FECA), longshore and harbor workers, coal miners under the Black Lung Benefits Act, and railroad workers. This is why the CMS-1500 Box 1 contains a checkbox for FECA BLK LUNG.
2. The Claim Lifecycle
Injury occurs
│
▼
Employee reports to employer (state deadline, often days)
│
▼
Employer files the First Report of Injury with the carrier and the state board
│
▼
Carrier assigns a CLAIM NUMBER and an ADJUSTER
│
▼
Provider verifies the claim number and adjuster BEFORE treating
│
▼
Treatment rendered ──► CMS-1500 to the CARRIER (not the health plan)
│
▼
Carrier pays the STATE FEE SCHEDULE amount = payment in full
The verification step is the one practices skip. Before the first visit, the office must obtain the carrier name, claim number, adjuster name and phone, date of injury, and the accepted body parts. A claim number is not proof of acceptance — carriers frequently accept a low back injury and deny a shoulder injury arising from the same incident. Treating and billing an unaccepted body part produces a denial that cannot be balance billed to the patient.
3. The Absolute Prohibition on Balance Billing
This is the single most heavily tested fact in the topic.
Under state workers' compensation statutes, the fee schedule amount is payment in full. A provider treating an accepted work-related injury may not bill the injured worker for any balance, and may not bill the worker's group health plan for the difference. Attempting to do so is a statutory violation in every state, independent of any contract the provider has signed.
| Situation | Group Health Plan | Workers' Compensation |
|---|---|---|
| Provider is out of network | Balance billing may be permitted, subject to the No Surprises Act | Never permitted |
| Charge exceeds the allowable | Written off contractually if participating | Always written off |
| Patient cost-sharing | Deductible, copay, coinsurance apply | None |
| Claim denied for a non-accepted body part | Patient may be billed | Not billable to the worker; dispute with the carrier or the state board |
| Patient asks for a "cash discount" to speed things up | Practice policy governs | Prohibited — the carrier is the payer |
Privacy Under Workers' Compensation
The HIPAA Privacy Rule expressly permits covered entities to disclose protected health information without patient authorization as authorized by, and to the extent necessary to comply with, workers' compensation laws. The employer and carrier are entitled to injury-related records. The limit is scope: the disclosure covers the work injury, not the patient's unrelated medical history. A carrier request for a complete lifetime record is a request the practice should narrow, not fill.
4. Completing the CMS-1500 for a Work Injury
Several fields behave differently than on a group health claim.
| Box | Group Health Entry | Workers' Compensation Entry |
|---|---|---|
| 1 | Check the applicable coverage type | Check OTHER (or FECA BLK LUNG for federal programs) |
| 1a | Subscriber's member ID | The carrier's claim number |
| 4 | Insured's name | The employer's name |
| 7 | Insured's address | The employer's address |
| 10a | Usually NO | YES — condition related to employment |
| 11 | Group or policy number | The workers' compensation claim number |
| 11c | Insurance plan name | The carrier name |
| 12/13 | Signature on file | Frequently not required; the carrier pays the provider directly |
| 14 | Onset of illness, with qualifier | The date of injury, with the appropriate qualifier |
| 16 | Usually blank | Dates the patient is unable to work — this drives the wage benefit |
| 19 | Narrative as needed | Adjuster name, authorization reference, body parts treated |
The diagnosis in Box 21 should reflect the injury and, where the state requires it, the external cause and place of occurrence codes that document how and where the injury happened.
5. Disability Claims Are a Different Product
Candidates conflate disability with workers' compensation because both involve time away from work. They pay for entirely different things.
| Workers' Compensation | Short-Term / Long-Term Disability | |
|---|---|---|
| What it pays | Medical treatment plus partial wage replacement | Wage replacement only — no medical bills |
| Injury must be work-related? | Yes | No — most disability covers off-the-job illness and injury |
| Who submits to the carrier | The provider, on a CMS-1500 | The employee, with a provider-completed form |
| The provider's document | The claim form | The Attending Physician Statement (APS) |
| What the provider certifies | Services rendered | Diagnosis, objective findings, functional limitations, expected duration, return-to-work date |
| Elimination period | None | Short-term typically 7-14 days; long-term typically 90-180 days |
Two federal programs sit alongside employer disability: Social Security Disability Insurance (SSDI), for workers with sufficient work credits and a disability expected to last at least 12 months or result in death, and Supplemental Security Income (SSI), which is needs-based. Neither pays the provider's medical claim; both may request records, which the practice supplies as a records request, not as a billing transaction.
The billing takeaway. A disability form is not a billable medical claim. Many practices charge an administrative form-completion fee to the patient for an Attending Physician Statement, which is permissible when disclosed in advance under the practice's financial policy — precisely because no payer is billed for it.
A provider treats an accepted work-related back injury. The state workers' compensation fee schedule allows $310 against a billed charge of $520. How is the $210 difference handled?
On a CMS-1500 submitted for a workers' compensation injury, what should be entered in Box 4 (Insured's Name)?
