Misdiagnosis in a Doctor’s Office: Arizona Malpractice Lawyers

Why Diagnostic Accuracy Matters in Doctor’s Offices

Most patients see a primary care physician or specialist before any hospital or urgent care visit. These providers are supposed to be the frontline defenders of health — ordering tests, identifying red flags, and referring patients for further evaluation when necessary.

But when doctors fail to recognize symptoms, dismiss patient concerns, or neglect proper testing, the result is misdiagnosis. This often leads to delayed treatment, disease progression, permanent injury, or wrongful death.

According to a Johns Hopkins University study, diagnostic errors are the leading cause of malpractice claims in the United States, responsible for nearly 40% of severe patient injuries.

In Arizona, families harmed by these failures deserve justice — and an experienced doctor’s office misdiagnosis lawyer to hold negligent providers accountable.

What Is Misdiagnosis in a Doctor’s Office?

Misdiagnosis occurs when a physician or medical provider:

  • Gives the wrong diagnosis for a condition.
  • Fails to diagnose an existing medical problem.
  • Delays diagnosis by ignoring symptoms or failing to order timely testing.

Unlike unavoidable complications, these failures often stem from preventable errors in clinical judgment.

Common Misdiagnosed Conditions in Doctor’s Offices

  • Heart disease and heart attack: Dismissed as acid reflux, stress, or muscle pain.
  • Stroke: Mistaken for migraine, vertigo, or anxiety.
  • Cancer: Symptoms ignored or attributed to minor illness until it spreads.
  • Diabetes: Overlooked during routine labs or attributed to lifestyle without testing.
  • Infections (sepsis, meningitis, pneumonia): Sent home as flu or viral illness.
  • Autoimmune diseases: Misinterpreted as depression, chronic fatigue, or fibromyalgia.
  • Appendicitis: Attributed to stomach upset or indigestion until rupture.
  • Pregnancy complications: Preeclampsia, ectopic pregnancy, or gestational diabetes ignored.

Each of these errors can result in catastrophic outcomes if left untreated.

Misdiagnosis in a Doctor’s Office

Why Misdiagnosis Happens in Doctor’s Offices

Misdiagnosis in physician practices is often the result of systemic flaws and individual negligence:

  • Rushed appointments, with doctors seeing dozens of patients daily.
  • Failure to take thorough patient histories.
  • Ignoring or dismissing symptoms, especially in women, children, or younger patients.
  • Overreliance on common conditions instead of ruling out serious ones.
  • Failure to order diagnostic tests like imaging, labs, or EKGs.
  • Poor communication with specialists or between providers.
  • Electronic health record (EHR) errors leading to missed information.

Doctors have a duty to provide reasonable care. When they fail, patients pay the price.

The Consequences of Doctor’s Office Misdiagnosis

The harm from misdiagnosis can be permanent and life-altering:

  • Disease progression: Cancer spreads, heart damage worsens, or infections become septic.
  • Permanent disabilities: Paralysis after stroke, kidney failure from untreated infections, or blindness from diabetes.
  • Delayed treatment options: Patients miss the window for life-saving therapies.
  • Wrongful death: Families lose loved ones when conditions are ignored or dismissed.
  • Financial devastation: Patients face higher medical bills and lost income due to worsened conditions.

For families, the hardest part is knowing that timely testing or referral could have prevented the outcome.

Arizona Law on Misdiagnosis Malpractice

Under A.R.S. § 12-561 et seq., Arizona law allows patients and families to file malpractice claims when diagnostic failures in a doctor’s office lead to harm.

Who Can File?

  • The patient, if living with permanent injury.
  • Surviving spouse, children, or parents in wrongful death cases.

The estate’s personal representative on behalf of beneficiaries.

Damages May Include:

  • Medical expenses: Hospitalization, surgery, rehabilitation, and long-term treatment.
  • Lost wages and reduced earning capacity.
  • Pain and suffering.
  • Loss of quality of life.
  • Wrongful death damages, including funeral expenses and loss of companionship.

Punitive damages in extreme cases of reckless negligence.

Proving Misdiagnosis in a Doctor’s Office

To win these cases, attorneys must prove:

  • Duty of care: The doctor had a professional obligation to provide competent evaluation.
  • Breach of duty: They failed to order tests, listen to symptoms, or recognize red flags.
  • Causation: The misdiagnosis directly caused harm, disability, or death.
  • Damages: The patient or family suffered measurable losses.

Evidence May Include:

  • Medical records from office visits.
  • Notes showing ignored or misinterpreted symptoms.
  • Lab results or imaging not ordered or reviewed.
  • Testimony from medical experts.
  • Autopsy reports in fatal cases.

Example: If a patient complained of chest pain but the doctor failed to order an EKG and later the patient died of a heart attack, liability may be clear.

Brian Snyder, attorney, was the only one who took my case more than five years ago.  I could not find an attorney in the state of Texas.  I spoke to many of the attorneys and law firms throughout Texas. I told them my symptoms were swollen lymph nodes, early signs of a recurrent hernia on my left groin, and I was always in pain.  No attorney wanted to help me throughout the state of Texas.  Brian Snyder, attorney, took my case without any hesitation.  He knew right away what I was going through.  Cause of Brian Snyder, I was able to get a settlement payment for an XL mesh plug and onlay.  I truly recommend Brian Snyder if any person is experiencing a recurrent hernia or mesh problems.  I truly recommend him as an attorney to get you results.  I consider Brian Snyder very sneaky, intelligent, with a lot of experience, and a view of common sense. Brian Snyder was very patience and understanding with my case. Brian Snyder is a very bright attorney. I wholeheartedly recommend that you give him a call. I am happy with the settlement and on my way to view and relax by the ocean. Thank you, Brian Snyder, for your help.

One can't begin to convey the immense gratitude we have for David Wenner. We were fortunate to have his highly skilled counsel for our brother, Richard who was involved in a life changing accident through no fault of his own. The enormity of his immediate medical needs and placement in ICU for several months was more complicated with us living out of state. David and his paralegal Jen showed their humanity and compassion in helping us to navigate the insurance and legal issues while staying abreast of Richard's ever-changing condition. They allowed us to concentrate on his care and recovery which was a true blessing. Richard continues to make progress, and he is indebted to David for helping to ensure his care for the future. Thank you, David & Jen !
