Mammoth Hospital realizes that hospital care can be expensive. To help meet the needs of low-income, uninsured and underinsured patients, Mammoth Hospital has a financial assistance program for full charity or discounted care to assist eligible patients who do not have the financial ability to pay their medical bills.
Based on current Federal Poverty guidelines, you may qualify for free or discounted care. If you are uninsured or underinsured with a family income at or below 200% of the Federal Poverty Level, you may be eligible to receive charity care financial assistance, i.e., hospital services at no cost to you. If you are uninsured or underinsured with a family income from 201% to 450% of the Federal Poverty Level, you may be eligible to receive discounted care, i.e., where your payment is reduced but is not more than the higher of the Medicare or Medi-Cal rate. To qualify, patients must meet the eligibility criteria outlined in the Financial Assistance Policy and complete a free Financial Assistance Application.
In order to determine your eligibility for financial assistance, you will need to complete the free Financial Assistance Application and provide additional supporting documents.
The Financial Assistance Policy, the Billing and Collection Policy and the Financial Assistance Application can be found below. Additionally, the Financial Assistance Application can be accessed in person at the Mammoth Hospital Patient Financial Counselor’s office, or by mail if requested by calling (760) 924-4148 or (800) 753-0414.
You may submit your Financial Assistance Application by email at: Billing@MammothHospital.com , in-person, or by mail to the Patient Financial Services Office at:

Welcome to Mammoth Hospital Price Transparency.
Federal law requires Mammoth hospital to make public a list of standard charges for the items and services we provide. This list must include gross charges, payer-specific negotiated charges, the minimum and maximum negotiated charge and the cash discount price for all items and services and services packages.
Please note that standard charges shown do not necessarily reflect the amount that a patient will pay for the services rendered. Actual cost to the insurer and/or patient, as well as the out-of-pocket amount for which a patient will be directly responsible, are determined by several factors not in the exclusive control of Mammoth Hospital.
We understand that health care costs, billing and insurance can be confusing. To obtain the most accurate estimate of patient out of pocket costs, it is strongly recommended that patients contact your insurer to request an estimate. We are available to address patient questions at 760-924-4148. To obtain the most accurate estimate possible, the patient’s insurance information, if any, as well as a detailed description of the requested service (physician order preferred) are necessary.
By accessing the list at the below link, I hereby acknowledge that I have read and am aware of the above information and recognize that this list cannot be used as a single source for determining actual cost to any payer, including insurers, employers, or patient out-of-pocket responsibility.
