CALIFORNIA MEDICAL BILLING ADVOCATES
EIN 83-4336436 · Public Finance, Taxation & Monetary Policy (W22)
What they do
Medical Bills Negotiation and Financial Education: Given The Complexity of The U.S. Healthcare System, Patients Often Receive Surprise Medical Bills Despite Having Health Insurance. Furthermore, Many Patients Who Are Underinsured or Uninsured Receive Grossly Inflated Medical Bills Directly From Hospitals and Doctors. Many Patients Cannot Afford to Pay These Bills and Let Them Turn Into Medical Debt, Which is One of The Leading Causes of Personal Bankruptcy In The U.S. CALMBA Believes That Many of These Bills Are Excessive and Unjust to The Patient. CALMBAs Mission is to Reduce or Eliminate Medical Bills, By Negotiating Lower Medical Bills On The Patients Behalf Using Financial, Legal, and Medical Tactics. CALMBA Focuses Its Efforts On Helping Economically Disadvantaged, Low Income, and Poor Patients. CALMBA Started Operations At The End of September 2019. During 2019, CALMBA Received 271 Inquiries for Assistance With Medical Bills, of Which We Accepted 161 Cases Totaling $3.7 Million I

Money made simple
Ask these three easy questions
- Who did you help? Ask for a recent story or report that shows real results.
- What will my money do? Ask exactly what your gift will pay for.
- Is this really the charity? Give only through its official website or confirmed phone number.
Worth asking: Expenses exceeded revenue by $819 this year. Ask whether that was planned or caused by a one-time event.
Bottom line: Do not decide from a name, mission statement, or tax status alone. Look at where the money went, then ask what changed, who was helped, and what your gift will do. YouCanGiveBack does not endorse or grade organizations.
Financial picture
A plain-language look at the latest Form 990 figures available. These numbers help you ask better questions; they do not, by themselves, rate whether a charity is good or bad.
How each $100 of revenue was used
The large number compares each expense with revenue. The smaller number shows its share of total expenses.
Expenses were greater than revenue, so the colored ring fills the available $100 and the total above 100% is shown below.
Has the pattern changed?
Colored bars = expense mix: how each year’s expenses were divided. Total expenses vs. revenue shows whether the charity spent less or more than it received. The current filing is first.
