Electronic Submission of Claims

Advantages of using EDI

Several immediate advantages can be realized by exchanging documents electronically, here are a few:

Ability to submit 24/7

L.A. Care accepts all claims electronically, including professional and institutional related submissions 24 hours a day, seven days a week.

Reduction of data entry and payment errors

Claims submitted electronically benefit from earlier detection of billing errors.  If your claim fails due to any pre-pass edit, the claim is returned back to your office for correction.  This editing reduces the likelihood of your claim being rejected or denied for payment once it enters the processing system.

Immediate verification of claims received

Receive immediate acknowledgement of claims received and confirmation through your clearinghouse within two days as to if claims have been accepted  or rejected.

In order to take advantage of EDI, you'll need to register with Change Health Care clearinghouse and reference L.A. Care’s Payer ID “LACAR”. 

L.A. Care Providers must bill with the most up-to-date current coding available for the date of services rendered.

Coordination of Benefits

In accordance with requirements of the Balanced Budget Act of 1997, as a secondary payer, L.A. Care will pay deductibles, co-insurance and co-payments for Medi-Cal covered services up to the lower of our fee schedule or the Medicare/other insurance allowed amount.

California law limits Medi-Cal’s reimbursements for a crossover claim to an amount that, when combined with the Medicare payment, should not exceed Medi-Cal’s maximum allowed for similar services (Welfare and Institutions Code, Section 14109.5). When a Member has other health insurance, whether it is Medicare, a Medicare HMO or a commercial carrier, L.A. Care will coordinate payment of benefits. These other insurers are considered the primary payer, and L.A. Care is the secondary or last payer.

Balance Billing

Balance billing is when a practitioner charges beneficiaries for Medi-Cal covered services. Balance billing L.A. Care Members is prohibited by law.

Contracted practitioners cannot collect reimbursement from a L.A. Care Member or persons acting on behalf of a Member for any services provided, except to collect any authorized share of cost co-insurance, co-payment or deductibles when applicable. 

Prohibition of Balance Billing

Practitioners participating in Medi-Cal and/or Medicare are prohibited from balance billing any L.A. Care Member eligible for Medi-Cal and/or Medicare. Network practitioners who engage in balance billing are in breach of their contract with L.A. Care.

Practitioners who engage in balance billing may be subject to sanctions by L.A. Care, CMS, DHCS and other industry regulators.

Timely Filing Deadline

L.A. Care cannot impose a timeframe for receipt of the first ‘initial claim’ submission that is less than 180 days for contracted practitioners after the date of service for timely filing for a new claim. L.A. Care may deny a claim that is submitted beyond the claim filing deadline.

Provider Disputes

A practitioner has a right to file a dispute in writing to L.A. Care within 365 day from the date of service or the most recent action date, if there are multiple actions. L.A. Care makes available to all practitioners a fast, fair and cost-effective dispute resolution mechanism for disputes regarding invoices, billing determinations or other contract, non-contracted issues. The dispute resolution mechanism is handled in accordance with applicable law and your agreement. A provider dispute is a written notice to L.A. Care challenging, appealing or requesting reconsideration of a claim. The following are examples of disputes:

  • Claims payment disputes: challenging, appealing or requesting reconsideration of a claim (or bundled group of claims)
  • Benefit determination disputes: seeking resolution of a benefit determination
  • Payment of a claim
  • Denial of a claim
  • Timely filing denial
  • Seeking resolution of a billing determination
  • Seeking resolution of another contract dispute
  • Disputing a request for reimbursement of an overpayment to a claim
Second Level Dispute

If you remain unable to resolve your billing and payment issues L.A. Care makes available to all practitioners a second level dispute process. Second level disputes must be sent to the following address:

L.A. Care Health Plan
Attention: Provider Disputes
P.O. Box 811610
Los Angeles, CA 90081

  • L.A. CARE will acknowledge receipt of disputes by mail within 15 calendar days of the date of receipt by L.A. Care.
  • L.A. Care will issue a written determination stating the outcome decision for its determination within.
