Arizona medical-malpractice cases involve specific procedural rules and (in many states) damages caps. No cap (constitutional protection).

## Medical malpractice claims in Arizona
When a doctor, hospital, nurse, or other healthcare provider hurts you by failing to meet the **standard of care** — what a reasonable provider in the same specialty would have done — you may have a medical malpractice claim. These cases are heavily regulated by state law.
### Damages caps in Arizona
No cap (constitutional protection).
### Certificate of merit / expert affidavit
Preliminary expert opinion required.
### Statute of limitations
2 years from discovery (max 4 years from injury via the discovery rule).
## What you have to prove
Every medical malpractice case requires four elements:
1. **Duty** — a doctor-patient relationship (or other provider-patient relationship)
2. **Breach** — the provider deviated from the standard of care
3. **Causation** — the breach actually caused the injury (not just that something went wrong)
4. **Damages** — actual harm — physical injury, additional medical bills, lost wages, pain and suffering
Causation is usually the hardest element. Many bad outcomes are not malpractice — bad results happen even with good care. Conversely, malpractice that doesn't worsen the outcome (because the patient would have died from the underlying disease anyway) generally fails on causation.
## Common malpractice scenarios
- **Misdiagnosis or delayed diagnosis** — particularly cancer, heart attack, stroke, infections
- **Surgical errors** — wrong site, wrong procedure, retained instruments, anesthesia errors
- **Birth injuries** — failure to monitor, delayed C-section, oxygen deprivation
- **Medication errors** — wrong drug, wrong dose, dangerous combinations, missed allergies
- **Failure to obtain informed consent**
- **Hospital-acquired infections** (some states)
- **Nursing home neglect** (often analyzed under different statutes)
## The expert witness problem
Medical-malpractice cases all but require a qualified medical expert who's willing to testify against another physician. Finding one is harder than it sounds:
- The expert usually must be in the same specialty as the defendant
- Many states require active practice (or very recent practice) by the expert
- Reputational and professional pressure discourages doctors from criticizing colleagues
- Expert fees run $500-$1,500/hour — a single case can require $20,000-$100,000 in expert costs
Plaintiff-side malpractice law firms typically have established expert networks and pre-screen cases hard before accepting them.
## Pre-suit panels and notice requirements
Many states require some pre-litigation step:
- **Medical review panels** (LA, IN, NM, etc.) — independent panel reviews and issues an advisory opinion BEFORE suit can be filed
- **Pre-suit notice** (FL, TX, GA, others) — written notice to the provider weeks/months before filing
- **Certificates of merit** — sworn statement (sometimes from an expert) that the case has merit
- **Mandatory mediation** — required attempt to settle before trial
Missing any of these is fatal in most jurisdictions.
## Why these cases are hard to win
- Juries trust doctors and are skeptical of plaintiffs
- Defense bar is well-funded by malpractice insurers
- Causation is often genuinely uncertain in complex medical cases
- Damages caps limit recovery, which limits attorney willingness to take cases
- Procedural traps (expert affidavit timing, panel rulings) defeat many cases before merits are ever reached
## What you should do
If you suspect malpractice in Arizona: get all your medical records (request in writing — providers must comply under HIPAA), keep a journal of symptoms and treatment, and consult a medical-malpractice firm for a free case review. Most med-mal attorneys work on contingency and are very selective about which cases they take. Don't talk to risk management or sign anything from the provider before consulting a lawyer.
