California Health and Wellness requires that Enhanced Care Management/Community Service (ECM/CS) providers submit fee-for-service professional claims on the paper CMS-1500 claim form, EDI 837 professional, or California Health and Wellness invoice form.
California Health and Wellness prefers that all claims be submitted electronically. Refer to electronic claims submission for more information.
For providers unable to send claims electronically, paper claims are accepted if on the proper type of form. Requirements for paper forms are described below.
Providers billing for professional services, and medical suppliers, must complete the CMS-1500 (version 02/12) form. The form must be completed in accordance with the guidelines in the National Uniform Claim Committee (NUCC) 1500 Claim Form Reference Instruction Manual Version 5.0 7/17.
If non-compliant, paper claims follow the same editing logic as electronic claims and will be rejected with a letter sent to the provider indicating the reason for rejection. When billing CMS-1500, California Health and Wellness only accepts standard claim forms printed in Flint OCR Red, J6983 (or exact match) ink.
Paper claim forms must be typed in black ink in either 10 or 12 point Times New Roman font, and on the required original red and white version of the form, to ensure clean acceptance and processing.
Claims submitted on black and white, handwritten or nonstandard forms will be rejected and a letter will be sent to the provider indicating the reason for rejection. These claims will not be returned to the provider. To reduce document handling time, providers must not use highlights, italics, bold text, or staples for multiple page submissions.
Copies of the form cannot be used for submission of claims, since a copy may not accurately replicate the scale and OCR color of the form. California Health and Wellness Plan does not supply claim forms to providers. Providers should purchase these forms from a supplier of their choice.
Providers unable to bill on CMS-1500 (02/12) must complete the California Health and Wellness Plan Invoice form. The form must be completed in accordance with the California Health and Wellness Plan invoice submission instructions.
All paper CMS-1500 (02/12) claims and supporting information must be submitted to:

Timely Filing of Claims
California Health and Wellness Plan will waive the Timely Filing of Claims for a reasonable period in the event that the provider provides notice to California Health and Wellness Plan, along with appropriate evidence, of extenuating circumstances that resulted in the delayed submission. California Health and Wellness Plan will determine extenuating circumstances and the reasonableness of the submission date. This in no way limits California Health and Wellness Plan's ability to provide incentives for prompt submission of claims.
Complete Claim Definition
A complete claim is a claim, or portion of a claim, that is submitted on a complete format adopted by the National Uniform Billing Committee and which includes attachments and supplemental information or documentation that provide reasonably relevant information, or necessary information, to determine payer liability.
Important Note: We require that all facility claims be billed on the UB-04 form.
California Health and Wellness Plan uses the National Uniform Billing Committee (NUBC) Official UB-04 Data Specifications Manual as the standard source for codes and code descriptions to be entered in the various form locators (FL). The National Uniform Billing Committee's UB-04 Data Specifications Manual is available here.
Correct coding is key to submitting valid claims. To ensure claims are as accurate as possible, use current valid diagnosis and procedure codes and code them to the highest level of specificity (maximum number of digits) available.
The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM), is currently used to code diagnostic information on claims. Multiple entities publish ICD-10-CM manuals and the full ICD-10-CM is available for purchase from the American Medical Association (AMA) bookstore on the Internet.
Use Healthcare Common Procedure Coding System (HCPCS) Level I and II codes to indicate procedures on all claims, except for inpatient hospitals. ICD-10-CM codes are used for procedure coding on inpatient hospital Part A claims.
For all other uses, Level I Current Procedural Terminology (CPT-4) codes describe medical procedures and professional services. CPT is a numeric coding system maintained by the AMA. The CPT code book is available from the AMA bookstore on the Internet.

Claims Coding Practice
Non-participating providers are expected to comply with standard coding practices. California Health and Wellness Plan uses code auditing software to improve accuracy and efficiency in claims processing, payment, and reporting. The software detects and documents coding errors on provider claims prior to payment by analyzing CPT/HCPCS, ICD-10, modifiers and place of service codes against correct coding guidelines. The following sources are utilized in determining correct coding guidelines:
- Centers for Medicare & Medicaid Services (including NCCI, MUE, and Claims Processing Manual guidelines)
- Public domain specialty provider associations (such as American College of Surgeons, American Academy of Orthopaedic Surgeons, etc.).
- State provider manuals and fee schedules.
- American Medical Association (CPT, HCPCS, and ICD-10 publications).
- Health plan policies and provider contract considerations.
- Clinical consultants who research, document, and provide edit recommendations based on the most common clinical scenario.
- In addition to nationally recognized coding guidelines, the software has flexibility to allow business rules that are unique to the needs of individual product lines.
California Health and Wellness Plan may request medical records or other documentation to verify that all procedures/services billed are properly supported in accordance with correct coding guidelines.
Specific ECM and CS Billing Requirements
The following are billing requirements for specific services and procedures.
- All Services: Prior authorizations are required for all contracted and non-contracting provider claims except in certain emergent situations.

Acknowledgment of Claims
California Health and Wellness Plan acknowledges electronically submitted claims, whether or not the claims are complete, within two business days via a 277CA to the clearinghouse following receipt. California Health and Wellness Plan acknowledges paper claims within 15 business days following receipt for Medi-Cal claims. If a paper claim is paid or denied within 15 days, the Remittance Advice (RA) is the acknowledgment of claims receipt. A provider may obtain an acknowledgment of claim receipt in the following manner:
- Medi-Cal claims: Confirm claims receipt(s) by calling the Medi-Cal Provider Services Center at 1-800-675-6110.
Claims received from a provider's clearinghouse are acknowledged directly to the clearinghouse in the same manner and time frames noted above.
Date of receipt
Date of receipt is the business day when a claim is first delivered, EDI, electronically via email, portal upload, fax, or physically, to California Health and Wellness Plan's designated address for submission of the claim.
Reimbursement of Claims
California Health and Wellness Plan reimburses each complete claim, or portion thereof, from a provider of service no later than:
- 45 business days for Medi-Cal plans
This time frame begins after receipt of the claim unless the claim is contested or denied. California Health and Wellness Plan reserves the right to adjudicate claims using reasonable payment policies and non-standard coding methodologies. These policies and methodologies are consistent with available standards accepted by nationally recognized medical organizations, federal regulatory bodies and major credentialing organizations.
Denied or Contested Claims
California Health and Wellness Plan notifies the provider of service, in writing, of a denied or contested Medi-Cal claim no later than 45 business days after receipt of the claim.
Date of contest or date of denial is the electronic mark or postmark date indicating the date when the contest or denial was transmitted electronically or mailed by U.S. mail.
A contested claim is one that California Health and Wellness Plan cannot adjudicate or accurately determine liability because more information is needed from either the provider, the claimant or a third party.
Incomplete claims or claims that require additional information are contested in writing by California Health and Wellness Plan in the form of an Explanation of Payment/Remittance Advice (EOP/RA), which may in some circumstances be followed by additional written communication within the timeframes noted above.
If California Health and Wellness Plan needs additional information before the claim can be adjudicated, the necessary information must be submitted within 365 days of the date of the EOP/RA that reflects the contested claim, in order to have the claim considered by California Health and Wellness.
The EOP/RA for each claim, if wholly or partially denied or contested, includes an explanation of why
California Health and Wellness Plan made its determination. Supplemental notices to contest the claim, describing the missing information needed, is sent to the provider within 24 hours of a determination.
If California Health and Wellness Plan has contested a claim, each EOP/RA includes instructions on how to submit the required information in order to complete the claim. Each EOP/RA reflecting a denied, adjusted or contested claim includes instructions on the department to contact for general inquiries or how to file a provider dispute, including the procedures for obtaining provider dispute forms and the mailing address for submission of the dispute.
Interest on Late Payment of Claims
Late payments on complete Medi-Cal claims that are neither contested nor denied automatically include interest at the rate of 15 percent per year for the period of time that the payment is late.
The late payment on a complete Medi-Cal claim for emergency room (ER) services that is neither contested nor denied automatically includes the greater of $15 for each 12-month period or portion thereof on a non-prorated basis, or interest at 15 percent per year for the period of time that the payment is late.
If California Health and Wellness Plan does not automatically include the interest fee with a late-paid complete Medi-Cal claim, an additional $10 is sent to the provider of service.
Overpayment of Claims
The California Health and Wellness Plan Provider Services Department is available to assist with overpayment inquiries. A provider who has identified an overpayment should send a refund with supporting documentation to:
California Recoveries Address:
California Health and Wellness Plan Overpayment Recovery Department
PO Box 886027
Los Angeles, CA 90088-6027
If California Health and Wellness Plan identifies an overpayment due to a processing error, coordination of benefits, subrogation, member eligibility, or other reasons, a notice is sent that includes the following:
- Member's name and ID number
- Provider's account number
- Date of service
- Amount of overpayment
- California Health and Wellness Plan's payment date
- Detailed reason for the refund request
Failure to comply with timely filing guidelines when overpayment situations are the result of another carrier being responsible does not release the provider from liability.
If the overpayment request is not contested by the provider, and California Health and Wellness Plan does not receive a full refund or an agreed-upon satisfactory repayment amount within 45 days from the date of the overpayment notification, a withhold in the amount of the overpayment may be placed on future claim payments.
Whenever possible, California Health and Wellness Plan strives to informally resolve issues raised by providers at the time of the initial contact. If an issue cannot be resolved informally by a customer contact associate, California Health and Wellness Plan offers its nonparticipating providers a dispute and appeal process.
