FAQs
1. What types of medical liens does MLM handle in California?
MLM supports lien management for workers’ compensation, personal injury (PI), and med-legal/QME/AME billing. Whether it’s initial lien filing, appeals (including SBR/IBR), or post‑settlement disbursement, we manage the entire lien lifecycle.
2. What are the deadlines for filing a workers’ comp lien in California?
In California, a lien claim must be filed within three years of the date services were provided, or within 18 months if services occurred after July 1, 2013.
3. Is there a fee to file a lien, and how is it paid?
Yes. Any lien for medical treatment filed on or after January 1, 2013 requires a $150 filing fee, payable electronically via E‑Form or Jet File through DWC procedures.
4. What happens if the lien is denied or claims are rejected?
If a second-review appeal is denied, MLM files an Independent Bill Review (IBR) within 30 days, incorporating the new $195 filing fee, and pursues successful resolution. When favorable, insurers must reimburse both treatment and filing fees. Our evidence-based process results in a high success rate.
5. Can we file liens if the provider isn’t part of the employer’s MPN?
Yes, if the employer has an MPN, only included providers may file. If not, any provider may. MLM handles required lien declarations in compliance with CA Labor Code § 4903.05 and SB 1160 reforms.
6. What documentation is required when filing a lien?
California rules require:
- Proof of lien submission,
- Declaration under penalty of perjury,
- Detailed itemized voucher,
- Verification of service and filing fee payment,
- Service on all necessary parties.
If any requirement is incomplete, the lien may be invalid or dismissed.
7. What is the lien resolution process with WCAB?
MLM handles both conference negotiation and litigation:
- File lien and prepare documentation.
- Attend lien conference to negotiate.
- Conduct lien trial if unresolved.
- Ensure payment and file satisfaction of lien with WCAB on behalf of provider.
8. What rights does the insurer have after payment is made?
Once a claims administrator remits payment, it cannot reclaim it, unless there’s a contract clause or court/WCAB order. This protection helps safeguard provider revenue from unreasonable rescindmentl.
9. Can liens affect personal injury settlements?
Yes. If a worker has both a workers’ comp claim and a personal injury case, the insurer may assert a lien on the PI settlement. Skilled negotiation ensures providers secure fair reimbursement while preserving settlement potential for the injured worker.
10. How does MLM’s Jet Filing system improve efficiency?
Using our proprietary Jet Filing technology, we electronically submit liens and claims, reducing errors, minimizing denials, and speeding up turnaround. You get clean submissions and faster payment, backed by certified coders and expert negotiators.
