When a workers’ compensation check stops arriving, the most useful first step is figuring out exactly why, because California law sets firm notice requirements and short deadlines for challenging an unexpected change in benefits. Waiting to see if the next payment shows up can cost an injured worker the chance to act while the dispute is still easy to fix.

Why Workers’ Compensation Benefits Stop Without Warning

A missed payment is rarely random. In nearly every case, the claims administrator has made a decision, even when no one explained it clearly. Some of the most common triggers include:

• Reaching maximum medical improvement (MMI). Once a treating physician determines that a condition has stabilized, temporary disability payments end, even if the worker has not returned to their job.
• Hitting the temporary disability cap. Temporary disability is generally limited to 104 weeks within five years of the date of injury under Labor Code Section 4656, and payments stop once that cap is reached regardless of recovery status.
• A utilization review denial. When a utilization review modifies or denies a treatment recommendation, the disability payments tied to that treatment can stop while the decision is disputed.
• A missed medical appointment. Skipping a scheduled evaluation with a treating physician or Qualified Medical Evaluator can pause indemnity payments until the appointment is rescheduled.
• An open investigation. Claims administrators generally have up to 90 days to investigate a claim under Labor Code Section 5402, and payments can fluctuate while that review is underway.
• Surveillance or suspected inconsistency. A reported activity that appears to conflict with stated work restrictions can prompt an insurer to pause benefits pending further review.
• A return-to-work offer. An insurer may stop temporary disability if it believes a job offer fits within the treating physician’s restrictions.
• An administrative error. Adjuster reassignments, address changes, and processing backlogs can all interrupt a payment schedule without representing an actual decision on the claim.

Confirm What Is Actually Happening With the Claim

Before assuming the worst, contact the claims administrator directly and ask specifically why the payment stopped, then request that explanation in writing. California regulations under Title 8 of the California Code of Regulations Section 9812 require claims administrators to send written notice when temporary disability payments are delayed, denied, or changed, including the reason for the change and what information, if any, is still needed. If that notice was never received, that omission itself may be worth raising. Keep a record of every call, letter, and payment, along with dates and the name of whoever was contacted.

The Rules Designed to Protect Injured Workers

California law gives injured workers several tools to push back when benefits stop without a valid basis:

• Automatic penalties for late payment. Labor Code Section 4650 adds an automatic 10 percent penalty to temporary or permanent disability payments made more than 14 days late, without the worker needing to prove the delay was unreasonable.
• Penalties for unreasonable delay or refusal. Labor Code Section 5814 allows an additional penalty of up to 25 percent of the amount delayed, or $10,000, whichever is less, when payment was unreasonably delayed or refused.
• Protection against retaliation. Labor Code Section 132a makes it unlawful for an employer to punish a worker for filing a claim or having a work-related disability.
• A path to dispute a treatment denial. After a utilization review decision, an injured worker generally has 30 days to request an Independent Medical Review through the Division of Workers’ Compensation.

Steps to Take When Benefits Stop Suddenly

1. Document everything. Save notices, emails, voicemail dates, and payment records, since gaps in the paper trail make every later step harder.
2. Request a written explanation. Ask the claims administrator to state in writing why the payment changed and what is needed to resume it.
3. File for Independent Medical Review if the cause is a treatment denial, and watch the 30-day window closely.
4. Contact the DWC Information and Assistance Unit if the claims administrator is unresponsive or the explanation does not add up.
5. Consider a Declaration of Readiness to Proceed if informal contact does not resolve the issue, which allows a worker to request a hearing before the Workers’ Compensation Appeals Board.

Important: Many of the deadlines tied to a stopped benefit, including the 30-day window to request an Independent Medical Review, run from the date a notice is served, not the date it is read. Letting a deadline pass can forfeit the right to challenge a decision, even when the underlying claim is strong.

When to Talk to a Workers’ Compensation Attorney

Some interruptions resolve with a phone call. Others point to a deeper dispute, such as a contested MMI finding, a pattern of late payments, or a termination that followed too closely after a claim was filed. A workers’ compensation attorney can review the claim file, identify which deadlines apply, and push back on a decision that was not properly supported.
