What Is California Labor Code §4903.6: Lien Filing Timing Rules?

Except as necessary to meet the requirements of Section 4903.5, a lien claim or application for adjudication shall not be filed or served under subdivision (b) of Section 4903 until both of the following have occurred: Sixty days have elapsed after the date of acceptance or rejection of liability for the claim, or expiration of the time provided for investigation of liability pursuant to subdivision (b) of Section 5402, whichever date is earlier.

What does Labor Code 4903.6 actually require?

It stops a medical or medical-legal lien from being filed too early, before the claim and the underlying bill have had their normal time to play out.

A lien claim under this rule comes from a medical provider or similar claimant owed money tied to the injury, not from the worker or the employer. Labor Code 4903.6 applies to that kind of claim, filed under subdivision (b) of Labor Code 4903. It sets conditions that must happen first: enough time has to pass after the claim is accepted or rejected, and the normal time to pay or dispute the specific bill has to run out too. Filing or serving the lien before both conditions are met does not fit the statute. The rule applies the same way across the state and does not turn on where the case is filed.

When can a lien claim actually be filed under Labor Code 4903.6?

Only after two things happen: 60 days pass from the claim decision, and the window to pay or dispute the specific bill closes.

Say a physical therapy clinic treated an injured worker and billed the claims administrator. The clinic cannot file a lien right away. First, at least 60 days must pass after the claim was accepted or rejected, or after the time allowed to investigate it runs out, whichever comes first under Labor Code 5402. Second, the normal window to pay or formally dispute that specific bill, set by Labor Code 4603.2 for treatment bills or Labor Code 4622 for medical-legal bills, has to expire too. Only once both conditions are met can the clinic file or serve its lien.

Does this filing delay apply to my attorney's fee?

No. Labor Code 4903.6 reaches only the medical and medical-legal expense liens described in subdivision (b) of Labor Code 4903.

Labor Code 4903 allows several kinds of liens: attorney's fees, medical and medical-legal expenses, certain living expenses, burial costs, and a few benefit-credit categories. Labor Code 4903.6 only delays the medical and medical-legal expense category. It does not touch an attorney's fee lien, and subdivision (e) says the filing delay does not apply to filings made by or for the worker or the employer. A worker should not assume this rule explains why an attorney fee has not been approved; that timing comes from Labor Code 4906 instead.

What is the Declaration of Readiness to Proceed rule under Labor Code 4903.6?

A lien claimant cannot ask for a lien hearing until the worker's own case is over, or the worker has decided not to proceed.

Once a medical lien is filed, the claimant eventually wants a hearing to get paid. Labor Code 4903.6 blocks that step early. A declaration of readiness to proceed cannot be filed for the lien until the underlying workers' compensation case has been resolved, or until the worker chooses not to go forward with that case. This keeps a lien claimant's payment dispute from slowing down or distracting from the worker's own claim. Our guide to California workers' comp forms covers this same rule as part of a wider look at the forms a claim produces.

Can a lien claimant see my medical records?

Only with limits. A non-physician lien claimant needs the appeals board's written approval first.

Labor Code 4903.6 restricts medical information for one type of lien claimant. A lien claimant who is not a physician cannot get an injured worker's medical information without the appeals board's prior written approval. An order allowing that access has to say exactly what information may be shared and explain why it is relevant to the lien. A lien claimant who is a physician is not covered by this particular limit, since that claimant typically already has the relevant treatment records.

How does Labor Code 4903.6 connect to the other lien rules?

It sets the earliest filing point. Separate sections set the latest filing deadline, the paperwork and fee, and the rules for an assigned lien.

Labor Code 4903 lists which claims can become a lien at all. Labor Code 4903.6 sets how early a subdivision (b) medical lien can be filed, while Labor Code 4903.5 sets how late one can be filed, normally 18 months from the date of service. Labor Code 4903.05 covers the paperwork, the proof of service, and the filing fee once a lien is ready to go. Labor Code 4903.8 covers who gets paid if that lien is later sold or assigned. For what actually happens once a lien reaches a hearing, see our lien conference guide.
