Your deadline: 3 years from the injuryRead the California law guide

Each step in more detail

Check the deadline
When you talk to the lawyer, give the dates of the injury and when you learned of a possible diagnostic error. Under California's general rule, you must file within 3 years of injury or 1 year of discovery, whichever comes first. If a child is involved, ask about that deadline separately.
Review the medical history
For the first review, bring both your chart and the later diagnosis. Before the lawyer decides whether to take your claim, ask what other records or medical opinions they need to review. A free consultation doesn't mean the lawyer has agreed to represent you.
Agree on representation
Before signing anything, read the written fee terms if the firm offers to take your claim. Find out who will be your lawyer, along with who must pay the costs of the case. Contingency arrangements are stated by four of the listed firms. Have each firm walk you through the agreement it proposes.
File the complaint
Filing a complaint begins the lawsuit. Although California doesn't require a certificate of merit to sue a health care provider for negligence, you must get court permission before you can claim punitive damages. Punishing conduct is the purpose of those damages.
Address the evidence and outcome
To understand how the lawyer would support your claim, ask how they'd use medical opinions and records, along with what might lead to settlement or trial. Only non-economic damages are capped in California; the applicable cap is the one in force at judgment, award or settlement. There's no cap on economic damages.

What a malpractice lawyer costs in San Francisco

The first callOften free. Ask before you book.
A written agreementThe share the lawyer takes, set out before work starts.
If you recover moneyThe agreed share and the case costs come out of it.
If the claim failsNo legal fee on a contingency agreement. Ask about costs.

Four firms here list contingency fees, which pay the lawyer a share of a recovery; if the claim fails, there's no attorney fee. Ask about Venardi Zurada's contingency terms, which aren't stated here. Separate case expenses include paying to obtain records or medical opinions, as well as court fees. The firm won't necessarily absorb those costs. If there's no recovery, ask who owes those expenses, as well as who pays them upfront. Before you sign, ask the lawyer to explain the fee share and how costs reduce your recovery, along with whether the free consultation leaves you with any further obligation.

A free consultation is offered by each of the five listed firms. Contingency arrangements are stated by four.

What to bring to your first call

Symptoms and appointments written out as a timeline through the eventual diagnosis
When you first suspected a diagnostic error or learned about one, with dates
Test results and imaging reports, together with the medical charts you already have
Who treated you, including clinicians' and hospitals' names
Records of lost earnings, together with your medical bills
Letters or messages you've received from the insurer or hospital
Photos relevant to the injury, if you have any
If the claim concerns a child, your child's birth date

Questions to ask a lawyer

1Has your work included a missed diagnosis of this condition?
2Who would take responsibility for my file as my lawyer?
3To assess my claim, what records or medical opinions would you need?
4When must I file, given my particular situation?
5What's the calculation for your contingency fee?
6If there's no recovery, who pays the case costs?
7How can I get updates and answers to questions?
8What do you see as my claim's main difficulties?

Choose around the missed diagnosis, not the firm's size

What happened medically comes first. When a spinal abscess is missed or a C-section is delayed, the chart and the resulting harm raise different questions. While Venardi Zurada describes a missed tumor diagnosis, Walkup Personal Injury Lawyers publishes results related to diagnoses. Has the firm worked on your condition? That question isn't answered by a general personal injury reputation.

Ask who will actually handle your file

The firm's name won't tell you who your lawyer is. Ask who makes the initial assessment and who stays responsible if the firm accepts your claim. Get a usable contact method. Morgan & Morgan's reviews include communication complaints; The Barnes Firm's reviews emphasize explanations and updates. Use those accounts to frame your questions, not to predict your experience.

Has the attorney handled your missed condition before, or worked on a claim involving a similar treatment delay?
Will you meet the lawyer who would handle your claim, or will that person just be gathering information?
Where would you meet them? The Oakland offices of Venardi Zurada and The Barnes Firm are outside San Francisco.
What language support does the assigned team offer if you need Spanish? Spanish is listed by Venardi Zurada and B & D Law Group, APLC.

Read the fee agreement before signing

At every listed firm, the consultation is free. Without paying for that conversation, you can ask about fees and whether the firm will take your claim (the consultation doesn't mean they've agreed to represent you). Contingency fees appear in four listings. Before agreeing, ask what share applies and whether you'll face separate charges for medical records or opinions. If the claim fails, who owes costs should be confirmed in writing.

Questions people ask

Which San Francisco firm has published results involving missed diagnoses?

For failure to diagnose a spinal abscess, Walkup Personal Injury Lawyers publishes a $9.49 million jury verdict; it also publishes a $5.5 million settlement for delayed diagnosis of an infection. Although Oakland firm Venardi Zurada describes a case involving a missed benign tumor diagnosis, it doesn't publish an amount. What happened in those cases? What another claim might recover can't be predicted from them.

How soon do I need to contact a California malpractice lawyer?

Don't delay contacting a lawyer. The longer deadline isn't necessarily the one you have. Under California's filing statute, a claim generally must be filed within 3 years of injury or 1 year after you discovered it, or reasonably should have discovered it, whichever comes first. When you give a California lawyer your dates, they can explain what the rule means for your particular circumstances.

Can I speak to one of these firms without paying for the consultation?

All five listed firms say they offer a free consultation. Four also list contingency fees, meaning attorney fees depend on a recovery. Venardi Zurada's contingency terms aren't stated here. Before proceeding, ask whether the consultation is free for your particular inquiry and request an explanation of any proposed fee agreement, including responsibility for case costs.

What does a lawyer need to assess a misdiagnosis claim?

Your medical records and a written account of what happened are the starting point. When describing your initial symptoms and the diagnosis you received, include when you were given a different diagnosis afterward. To assess your claim, the lawyer can tell you what other records or medical opinions they need to review. If you're filing a negligence lawsuit against a health care provider in California, you don't need a certificate of merit. That doesn't mean there's support for your particular claim.

How long will a misdiagnosis case take?

For these firms, no supported estimate of case length is available. After the lawyer reviews your chart, ask which steps they expect to take and what could hold things up. Although the filing deadline sets when you must bring the claim, it doesn't tell you when the case will finish. While the firm assesses or pursues your claim, how will you hear about its progress?

Does California have a different deadline for a child's claim?

It does. Within 3 years of the wrongful act, a child must sue. If the child is under 6, the deadline falls at the later of 3 years or the eighth birthday. When you speak to the lawyer, give your child's birth date and the date of the suspected error. Rather than applying the adult discovery rule yourself, ask a California lawyer to explain which deadline applies to your child.

Does California limit what a malpractice claim can recover?

Under California's MICRA, only non-economic damages are capped; these cover harms such as pain and suffering, rather than losses measured in money. Economic damages have no cap. When judgment, award or settlement occurs, the non-economic cap in force then is the one that applies. Have your lawyer explain where each loss fits and which cap would apply. This page doesn't give a cap amount.

What if my loved one died after a missed diagnosis?

Wrongful death appears among the practice areas or site topics of each of the five firms. Although those listings don't show whether you have a claim, they offer a starting point for asking about a death after a diagnostic delay. For that conversation, bring any records you have and the treatment timeline. To learn who may bring a claim and when it must be filed, ask a California lawyer.

Do I need a lawyer with an office inside San Francisco?

Where would you meet them? While Morgan & Morgan identifies an office in the San Francisco area, Walkup Personal Injury Lawyers and B & D Law Group, APLC have offices in San Francisco itself. In Oakland, you'll find offices of Venardi Zurada and The Barnes Firm. Before you decide whether you can manage the travel, find out where you'd meet and which lawyer would actually handle your file.
