How Much Does Workers' Comp Pay for Knee Surgery in California?

Workers asking about knee surgery pay are really asking four questions. Who pays the surgeon? What replaces lost wages during recovery? What is the lasting impairment worth? Is future knee treatment covered after settlement?

California law answers each question differently. The carrier pays authorized medical providers directly. Temporary disability replaces wages at two-thirds of pre-injury earnings. Permanent disability is a formal rating based on the final medical report. Future medical is either preserved in a Stipulation or bought out in a Compromise and Release.

Below: how each benefit type works. What affects the PD rating. Why closing future care too early can cost more than the settlement gains.

How does workers' comp pay for the knee surgery itself?

When the insurer authorizes knee surgery, the carrier pays the surgeon, hospital, and anesthesiologist directly. The worker does not pay out of pocket for authorized care.

Under Labor Code 4600, the employer must provide all needed care. That care must cure or relieve the work injury. For a knee claim, that includes imaging, specialist visits, and surgery. The treating physician documents the medical necessity. When UR approves the surgery, the carrier pays the providers directly. Payment follows the workers' comp fee schedule.

Take a supermarket stocker who tears an ACL loading pallets. That worker should not receive a surgical bill. Not if the injury is accepted and the surgery is approved. The worker's obligation is to attend authorized appointments and follow the treatment plan. The carrier's obligation is to pay for it.

If UR denies the surgery, the worker has 30 days to request IMR. IMR is free to the worker. A well-documented IMR packet addressing the MTUS criteria for knee surgical candidacy wins most reviews.

What wage replacement is available during knee surgery recovery?

Temporary disability under Labor Code 4653 pays two-thirds of lost wages. The state maximum rate applies. The benefit runs while the treating physician certifies you cannot do your regular job. It also runs when the employer cannot provide work within your medical restrictions.

TD starts when the treating physician issues work status slips documenting total or partial disability. Take a postal carrier who cannot walk a route after knee surgery. Total temporary disability pays two-thirds of pre-injury weekly earnings, up to the state maximum. If the employer offers light duty within the restrictions, TD may reduce. It depends on the wage difference.

The treating physician's work status notes are the foundation of the TD claim. Vague notes that say only 'light duty' give the insurer room to argue. Without specific limits, the insurer can claim the worker can return to full duty. Notes that specify standing limits and walking limits protect the TD benefit. Stair and ladder restrictions and weight limits matter too. Clear notes prevent premature return-to-work arguments.

What is the permanent disability rating for a knee injury?

Permanent disability is rated after the worker reaches maximum medical improvement. The rating is based on the treating or evaluating physician's impairment finding. The Permanent Disability Rating Schedule then applies.

When the condition stabilizes, the treating physician declares the worker Permanent and Stationary. That status means further treatment will not produce significant improvement. At that point, the physician issues a report rating the impairment. The rating uses the AMA Guides Fifth Edition. The WCAB Permanent Disability Rating Schedule converts that impairment to a percentage. The percentage determines the weekly PD benefit and how many weeks it runs.

Knee ratings vary widely depending on the final impairment. A meniscectomy with full return to prior motion may yield a low impairment percentage. A total knee replacement with significant motion loss and permanent restrictions may yield a substantially higher rating. The treating physician describes range of motion, stability, pain, and function. That report sets the starting impairment value.

Should I keep future medical care open or close it in settlement?

A Compromise and Release closes future medical care. It trades treatment rights for a lump sum. For knee injuries with ongoing needs, a Stip preserving open medical care is often worth more over time.

The decision depends on the expected future treatment. A worker with a full recovery and minimal ongoing needs can reasonably consider a C&R. A worker likely to need future knee replacement should evaluate those costs before closing medical. The same applies to periodic injections, physical therapy, and pain management. Closing future medical too early shifts those costs to the worker permanently.

Past results in workers' comp cases are not a reliable predictor of future settlement values. Every claim has different wages, different impairment findings, different disputed issues, and different apportionment considerations. The right approach is to build a clean medical and wage file. That way, each benefit type is counted accurately.

• §4600 - Employer duty to provide all medically necessary treatment including knee surgery
• §4653 - Temporary disability indemnity: two-thirds of lost wages during recovery
• §4656 - 104-week TD cap for most injuries
• §4660 - Permanent disability rating using AMA Guides Fifth Edition
• §4663 - Apportionment of permanent disability to non-industrial causation

How Yazdchi Law Handles Knee Surgery Claims

A knee surgery claim has multiple moving parts. Yazdchi Law tracks medical approvals, wage checks, and the PD rating. Nothing falls through the cracks.

Most workers see knee surgery claims as a two-part problem: get the surgery and recover. The workers' comp system adds a third part. That part is protecting every benefit. Carriers do not tell workers about open medical Stipulations. They do not explain PD rating implications of the treating physician's final report. An attorney does.
