Attention Data Users
Please exercise caution when interpreting OSHPD data. The use of improper assumptions and analytical methods may result in erroneous or misleading conclusions. Conclusions drawn from OSHPD data are the sole responsibility of the user.

The submitted pricing information reflects hospital charges in effect on June 1. As a result, a patient's bill for hospital services provided at a different date may contain different charges. Because each hospital is allowed to determine which 25 outpatient procedures to report to OSHPD, comparisons between hospitals' lists of charges for outpatient procedures may not always be possible.

OSHPD does not have the authority to intervene between patients and hospitals involving billing issues. If you are experiencing problems or have questions regarding your hospital bill that the hospital is not able to fully address, then it is recommended that you contact a not-for-profit patient advocacy group, such as Health Access California for assistance.

About Chargemasters

A hospital charge description master, also known as a chargemaster or CDM, contains the prices of all services, goods, and procedures for which a separate charge exists. It is used to generate a patient's bill. As required by the Payers' Bill of Rights, each hospital is required to submit a copy of its chargemaster, a list of average charges for 25 common outpatient procedures, and the estimated percentage change in gross revenue due to price changes each July 1.

It is important to note that the State of California does not currently possess the authority to set or limit the prices that are included on the submitted hospital chargemasters. Furthermore, the submitted chargemasters are reviewed for compliance with the statutes specified below, and a full audit of this information is not performed. Therefore, the Office of Statewide Health Planning & Development (OSHPD) is not able to provide an assessment on the accuracy of the submitted information and is not responsible for this information in any manner. The responsibility for any of the submitted data provided regarding the chargemasters rests with hospital management.

The chargemasters are currently not required to be provided in a standardized format. Therefore, it is currently not possible to generate an aggregate statewide chargemaster.

Hospital chargemasters and related pricing information are available online. To purchase/order a copy of hospital chargemaster information on CD/DVD, please call the Healthcare Information Resource Center (HIRC) at (916) 326-3802 and staff will assist you with your order.

AB 1045 and the Payers′ Bill of Rights

AB 1045 (Chapter 532, Statutes of 2005) amended the Payers' Bill of Rights established by AB 1627 (Chapter 582, Statutes of 2003). These statutes require all licensed general acute care hospitals, psychiatric acute hospitals, and special hospitals in California to make certain pricing information available to the public and to submit this information annually to OSHPD. Health facilities licensed as a Chemical Dependency Recovery Hospital or a Psychiatric Health Facility are exempt from these requirements.

The Payers′ Bill of Rights still requires each licensed hospital to make a written or electronic copy of its chargemaster available at the hospital′s location or on its website. A hospital that is statutorily classified as "small and rural" is exempt from making its chargemaster available on-site.

To view the Payers' Bill of Rights visit the California Law website. Follow the prompts to search for Health and Safety Code 1339.50 - 1339.59.

OSHPD has adopted regulations for reporting hospital chargemasters and related pricing documents in compliance with AB 1627 and AB 1045.

If any person feels that a hospital is in violation of the Payers' Bill of Rights, they may file a claim with the California Department of Public Health (CDPH), who is responsible for investigating such claims and informing that person of its determination on whether a violation has occurred and what actions it will take. This process would also pertain to any person who has no healthcare coverage and requested a written estimate from a hospital for healthcare services, procedures and supplies or requested information and/or an application for financial assistance or charity care and received no response from the hospital. You can visit the Licensing and Certification Division contact page to determine which CDPH location to contact (the local district office in the county where the hospital is located).

Major Changes to Payers' Bill of Rights

Effective January 1, 2006, AB 1045 requires each hospital to provide upon request a written estimate of the amount the hospital will require an uninsured person to pay for hospital services that are reasonably expected to be provided, based on average length of stay and services provided for the person's diagnosis. Estimates are not required for emergency services. Each hospital is also required to provide information about the hospital's financial assistance and charity care policies to uninsured patients, along with contact information for a hospital representative, to obtain more information about these policies.

In addition, AB 1045 adds the provision that a hospital may be liable for a $100 per day civil penalty if it does not file the required information to OSHPD.

Lastly, each hospital is required to provide a list of charges for 25 common outpatient procedures and an OSHPD-developed list of charges for common inpatient DRGs to any person upon request.

Reporting Requirements

AB 1045 repealed the requirement that each hospital annually submit a list of 25 services or procedures commonly charged to patients. Instead, each hospital is required to annually submit a list of charges for 25 common outpatient procedures beginning July 1, 2006. OSHPD has developed an optional reporting form for hospitals to report the list of average charges for 25 common outpatient procedures including instructions for completing the form. Hospitals are encouraged to use the optional form to report the required list of average charges for 25 common outpatient procedures. Instructions can be found here. To download Statewide Benchmark Top 25 DRGs based on a hospitals inpatient services, click here.

Two reporting requirements established by AB 1627 remain intact. Each hospital is still required to annually submit a copy of its chargemaster and an estimate of the percentage change in the hospital's gross revenue due to any price change during the 12-month period beginning with the effective date of the previous chargemaster filed. The initial reporting of the estimate calculation and supporting documentation will commence July 1, 2006, using the prices in effect on June 1, 2005 as the beginning date.

Each hospital must submit the above documents together as attachments to one e-mail to OSHPD at chargemaster@oshpd.ca.gov, or submit on one Compact Disc (CD) by mail to: Office of Statewide Health Planning and Development, Accounting and Reporting Systems Section, 2020 West El Camino Avenue, Suite 1100, Sacramento, CA 95833.

To obtain modifications to the requirements specified for electronic file formats, effective date of the documents, submission date of the documents, or methods of submitting electronic files, hospitals must file written requests for modification with OSHPD. Hospitals must have an OSHPD-approved modification prior to implementation of any change to the applicable requirements. Modification requests shall specify the precise changes being requested and the reason(s) the changes are needed. OSHPD will either approve or disapprove requests for modification on a case-by-case basis.

FAQs: Hospital Chargemaster Reporting (as of 5/22/06)

AB 1045 (Chapter 532, Statutes of 2005) revised the Payers' Bill of Rights, which were established by AB 1627 (Chapter 582, Statutes of 2003) and located in California Health and Safety Code 1339.50 to 1339.59. The replies to the following FAQs are based on our interpretation of the revised statutory requirements and/or the adopted regulations.

  • 1. What is the purpose of submitting pricing inforation?
    The purposes of this bill are to provide patients, health plans and healthcare purchasers with more information about charges for hospital care; and to discourage hospitals from establishing charges that adversely affect private payers and patients.
  • 2. What information is required to be made publicly available on location?
    Beginning July 1, 2004, each hospital is required to make a written or electronic copy of its charge description master (chargemaster) available on location. A hospital may elect to have an electronic or written copy available or to post a copy on its Internet website. Hospitals designated as "small and rural" according to Section 124840 of the Health and Safety Code are exempt from this requirement.

    Each hospital that is required to make its chargemaster available must also post a clear and conspicuous notice about its availability in its emergency department, admissions office, and billing office.

    Also beginning July 1, 2004, each hospital was required to provide a copy of its list of 25 commonly charged services or procedures to any person upon request. The passage of AB 1045 repeals this requirement on December 31, 2005.

    Beginning January 1, 2006, each hospital is now required to provide a list of charges for 25 common outpatient procedures and common inpatient procedures grouped my Medicare DRG. The DRG list is to be determined and provided by OSHPD to each hospital.

    Also beginning January 1, 2006, each hospital is required to provide upon request a written estimate of the amount the hospital will require an uninsured person to pay for hospital services that are reasonably expected to be provided, based on average length of stay and services provided for the person's diagnosis. Estimates are not required for emergency services. Each hospital is also required to provide information about the hospital's financial assistance and charity care policies to uninsured patients, along with contact information for a hospital representative, to obtain more information about these policies.
  • 3. What information is required to be filed with OSHPD? How often?
    The Payers' Bill of Rights currently requires each hospital to annually submit three documents to OSHPD regarding its prices:
    • A copy of its chargemaster.
    • A list of average charges for 25 common outpatient procedures.
    • The calculated estimate, along with supporting documentation, of the percentage change in gross revenue (charges) due to price changes. The gross revenue percentage estimate must be submitted along with the other two documents beginning July 1, 2006, and every July 1 thereafter. The reason for the one-year delay is because the estimate is to be based on the 12-month period beginning with the effective date of the last chargemaster filed with OSHPD.

    AB 1045 modifies these requirements by replacing the list of 25 services or procedures commonly charged to patients with a list of charges for 25 common outpatients procedures.

  • 4. Can we request an extension?
    The law does not provide OSHPD with the authority to grant an extension.
    AB 1045 added the provision that a hospital may be liable for a $100 per day civil penalty if it does not file the required information to OSHPD.
  • 5. Are all hospitals required to submit this information?
    Every general acute care hospital, psychiatric acute hospital, and special hospital licensed under Section 1250 (a), (b) and (f), respectively, is required to file these reports. Only health facilities licensed as a Chemical Dependency Recovery Hospital or Psychiatric Health Facility are exempt.

    Hospitals that do not provide outpatient services are exempt from submitting the list of 25 common outpatient procedures. OSHPD will review submitted annual financial disclosure reports as confirmation.
  • 6. Is a rural hospital required to submit its chargemaster to OSHPD?
    Yes. All rural hospitals are required to submit the required pricing information to OSHPD. However, a hospital defined as "small and rural" according to Section 124840 of the Health and Safety Code is exempt from making a written or electronic copy of its chargemaster available at the hospital's location or posting a copy on the hospital's Internet website.
  • 7. Is there a penalty for non-submission?
    Yes. AB 1045 adds the provision that a hospital may be liable for a civil penalty of $100 per day if it does not file the required information to OSHPD.
  • 8. What is the required method of submission?
    Documents must be submitted by e-mail to a designated e-mail address or by mail on CD. Submission by e-mail is preferred.
  • 9. Are there any restrictions to file types that can be sent?
    Yes. File types are restricted in order to facilitate processing, handling, and analysis. Acceptable file types include Microsoft Excel (.xls) and Comma Separated Value (.csv).

    Note: Hospitals using Microsoft Excel may submit all required items in a single file, as long as each item is placed in a separate worksheet tab.
  • 10. Where should we send our chargemaster and other documents?
    E-mail: Chargemaster

    Mail CDs to:
    Michael Nelson
    Office of Statewide Health Planning and Development

    Note: To help OSHPD keep track of submitted files, it is advisable that a cover letter accompany the submitted files, identifying by filename the contents of that file. Descriptive filenames would also help.
  • 11. Our chargemaster exceeds the maximum allowable rows (65,536) provided in Microsoft Excel. Can we submit two files or should we create two worksheets within the same file?
    It would be preferable to submit multiple worksheets within a single file.
  • 12. Can submitted electronic files be compressed (zipped)? Is there a maximum file size limit for e-mail submission?
    Yes to both questions. If files are too large to be sent as e-mail attachments, they may be zipped. If e-mail with attachments exceeds 10Mb, documents must be submitted on CD. Documents submitted on CD may also be zipped.
  • 13. Can a hospital submit hardcopy documents?
    No. Hardcopy reports will not be accepted.
  • 14. A typical chargemaster includes detailed information, such as charge codes, General Ledger codes, billing descriptions, revenue codes, billing codes, CPT/HCPCS codes, RVS codes, modifiers, and multiple prices. Are there any requirements on the specific chargemaster items to be included?
    No. OSHPD does not have authority to specify which chargemaster items are to be made available on location or reported to OSHPD. However, it is expected that the reported items and effective pricing date of both chargemasters would be the same. Each hospital will have to make that determination based on the statutory definition provided below:

    "Charge description master" means a uniform schedule of charges represented by the hospital as its gross billed charge for a given service or item, regardless of payer type.

  • 15. What should be included in the list of 25 common outpatient procedures required by AB 1045? Is there a required format (report layout) that must be used?
    Each hospital can choose which 25 outpatient procedures to include on its list. Reported items do not necessarily have to be the most common outpatient procedures. It is expected that a combination of ambulatory surgical procedures, outpatient diagnostic procedures, and outpatient therapeutic procedures will be reported.

    There is not a specified report format, but it is expected that each procedure listed would include at least a description of the procedure and its related charge.

    OSHPD has developed an Excel form and instructions for submitting the average charge for 25 common outpatient procedures. Use of the OSHPD form is voluntary, but encouraged. The form contains 50 common outpatient procedures, separated into sections according to CPT code classification. Hospitals must report the average charge for at least 25 procedures to comply with AB 1045, but may report charges for more than 25 procedures. To help hospitals meet the minimum 25 procedure requirement, the average charge for up to 10 unlisted procedures may be reported.
  • 16. Our hospital consists of multiple hospital locations operating under a consolidated license, where some locations have their own chargemaster. How should this be reported to OSHPD?
    If a hospital location operating under a consolidated license has a different chargemaster than the other location(s) operating under that same license, it is expected that a separate chargemaster and set of documents would be filed for that hospital location. Additionally, it is expected that a separate list of 25 common outpatient procedures would be submitted.
  • 17. Our hospital has separate chargemasters for inpatient acute care services and outpatient clinical services. Do we have to submit the chargemaster for the outpatient clinical services?
    Yes. All services that are provided under the hospital's general acute care license should be reported. If you are unable to combine the chargemasters into a single document, you may file them separately. If you are using Microsoft Excel, you may submit each chargemaster as a separate worksheet in the same document.
  • 18. What are the reporting requirements to OSHPD when separately licensed hospitals share a common chargemaster?
    Each separately licensed hospital is required to file a separate chargemaster and set of documents to OSHPD. While the chargemaster could be the same for both facilities, you should delete any service, good, or procedure that is not provided at a particular hospital. Further, it is expected that the list of 25 outpatient procedures and the gross revenue percentage calculation would be different.
  • 19. How should pharmaceuticals be reported if these items are formula-driven and the pharmaceutical items and/or prices do not appear separately in the chargemaster?
    All items for which a charge is made are to be included in the chargemaster filed with OSHPD. This may require you to manually enter the average wholesale price plus mark-up for each item as of June 1. Submitting pharmaceutical items in a separate file is allowed; or if you are using Microsoft Excel, as a separate worksheet within the same file.
  • 20. Our chargemaster is constantly being updated. Are we required to submit another chargemaster after each update?
    No. Chargemasters are to be submitted annually every July 1, beginning in 2005, even though it is acknowledged that they are frequently updated.
  • 21. Can I obtain a copy of another hospital's chargemaster from OSHPD?
    Yes, chargemasters and related pricing information are available on-line. Also available is a CD/DVD product that contains submitted documents for all hospitals for a reporting year.

    Contact OSHPD's Healthcare Information Resource Center (HIRC) at (916) 326-3802 or E-mail: HIRC for more information.
  • 22. What are the chargemaster reporting requirements when a hospital changes licensure (ownership) during the year?
    The licensee operating the hospital on June 1 is responsible for meeting the July 1 chargemaster reporting requirements for that calendar year.
  • 23. Is there a specified effective date for producing the chargemaster and other documents?
    Each hospital is required to submit the prices in effect on June 1 for the chargemaster, the list of charges for 25 common outpatient procedures, and the calculated estimate of percentage change in gross revenue that are due on July 1.

  • 24. AB 1045 requires OSHPD to establish a statewide list of the 25 most commonly performed inpatient DRGs and to develop a list of each hospital's average charges for applicable DRGs. AB 1045 also requires each hospital to provide this list to any person upon request. How do we obtain this information?
    OSHPD has developed a downloadable Excel pivot table called Statewide Benchmark Top 25 DRGs that meets this requirement using the patient-level data submitted by each hospital for each inpatient discharge. OSHPD will annually update this product.
  • 25. Our chargemaster contains blank prices for several items because some items are not charged to patients, some are used for statistical counting purposes, and others are no longer provided. How should this be reported to OSHPD?
    It is recommended that you indicate why prices are not reported for each blank item, or else it may be assumed that there is no charge. Reasons can be included on the chargemaster or in a cover letter.
  • 26. Who should I contact if I feel a hospital is in violation of the Payers' bill of Rights?
    You can contact the California Department of Public Health (CDPH) at the local district office in the county where the hospital is located. Phone numbers for CDPH can be obtained on their Licensing and Certification Division contact page.
  • 27. Are hospitals required to provide a written estimate for healthcare services, procedures and supplies at the request of patients who have no healthcare coverage?
    Yes, According to the Payers' Bill of Rights, a hospital must provide a written estimate of the amount the hospital will require the patient to pay for healthcare services, procedures, and supplies that are reasonably expected to be provided to the patient by the hospital. A hospital must also provide information and/or applications about financial assistance or charity care to patients that requested an estimate and contact information for a hospital employee or office from which the patient can obtain the information . If a hospital does not comply with this provision, a patient may contact the California Department of Public Health (CDPH) at the local district office in the county where the hospital is located. Phone numbers for CDPH can be obtained on their Licensing and Certification Division contact page
