Retained Surgical Items in Florida: Never Events, the Chapter 766 Process, and Proving the Claim

Modern surgery asks a team to keep track of hundreds of small objects — sponges, needles, clips, guidewires, retractors — inside a cavity that nobody can fully see, often under time pressure and across shift changes. The counting protocols built around that problem work the overwhelming majority of the time.

When they fail, the failure is concrete. A sponge, a broken instrument tip, or a needle stays behind in a patient who was told the operation went well, and the resulting infection, obstruction, or chronic pain frequently does not surface for weeks or months.

We understand that learning an object was left inside you is disorienting in a way that other injuries are not. It converts what felt like a completed recovery into an open question about everything else that happened in that operating room.

Retained surgical items occupy an unusual legal position in Florida. Nationally they are classified as never events — occurrences that should not happen when standard safeguards are followed — and yet a Florida claimant must still complete the same pre-suit corroboration process that governs every other claim in our surgical error practice area.

The never event label comes from patient-safety reporting frameworks rather than from Florida law. "Unintended retention of a foreign object in a patient after surgery or other invasive procedure" appears on the Serious Reportable Events list maintained through the National Quality Forum, which is where most of the terminology in hospital risk-management files originates.

The designation carries real institutional weight. Medicare treats a foreign object retained after surgery as a hospital-acquired condition, which generally means the facility cannot bill for the corrective care the retention makes necessary.

Florida layers its own reporting duty on top of that. Florida Statute § 395.0197 requires licensed facilities to operate an internal risk management program and to report defined adverse incidents to the Agency for Health Care Administration, and a retained foreign object generally falls within the categories a facility must review internally.

That said, none of this substitutes for a claim. The classification creates no private cause of action, establishes nothing about whether the retention caused your specific injuries, and excuses not one step of the statutory pre-suit process.

Keep in mind that facilities file these reports understanding them as safety documents rather than admissions of liability. What the classification does give you is a documented institutional acknowledgment that the event belongs to a category the industry itself considers preventable.

The provision that matters most here is Florida Statute § 766.102(3)(b), which provides that the discovery of the presence of a foreign body — a sponge, clamp, forceps, surgical needle, or other paraphernalia commonly used in surgical, examination, or diagnostic procedures — is prima facie evidence of negligence on the part of the health care provider. Confirm the current subsection numbering with counsel, because Florida has amended and reorganized portions of these chapters in recent legislative sessions.

Prima facie evidence is powerful and frequently misunderstood. It means the discovery of the object, standing alone, can carry the negligence question to a jury without an expert first explaining why leaving a sponge inside a patient falls below the standard of care.

However, prima facie is not conclusive. The defense may rebut it, and the rebuttals raised in these cases are more varied than most claimants expect.

Common defense positions include but are not limited to:

• Intentional placement. The item was deliberately left as therapeutic packing with a documented plan for later removal, which shifts the argument to whether that plan was communicated and followed.
• Attribution to a different procedure. The object is claimed to originate from an earlier surgery performed elsewhere, which makes the full operative history and the item's manufacturer markings central.
• Device fragmentation. A portion of an instrument, catheter, or guidewire separated because of a product failure rather than a counting failure, which can bring a manufacturer into the case.
• Causation rather than negligence. The provider concedes the retention but disputes that the object caused the infection, adhesion, obstruction, or chronic pain the claim is built on.

Notice that three of those four positions fight on attribution and causation rather than on the count itself. This is why a retained item claim is rarely as straightforward as the never event framing suggests, and why the evidentiary work described below decides most of these cases.

Florida requires a structured pre-suit process before a medical negligence complaint may be filed, and the foreign body rule creates no exception to it. The sequence is statutory, and a missed step can end a meritorious claim on procedure alone.

The core requirements include:

• A reasonable pre-suit investigation. Florida Statute § 766.104 conditions the filing of a medical negligence action on a good faith investigation that reasonable grounds exist to support the claim.
• A verified written medical expert opinion. Under § 766.203(2), the claimant's investigation must be corroborated by a verified written medical expert opinion from a qualifying expert.
• A notice of intent. Section 766.106(2) requires service of a notice of intent to initiate litigation on each prospective defendant before suit may be filed.
• The 90-day investigation period. Under § 766.106(3), each prospective defendant has 90 days to investigate and respond, and the limitations period is tolled during that window.
• Informal discovery. Section 766.106(6) permits unsworn statements, document production, and written questions before litigation formally begins.
• The response. The defendant must reject the claim, make a settlement offer, or offer to admit liability and arbitrate damages, and each of those answers changes the strategy that follows.

Read together, these provisions mean that a claimant who first learns about a retained sponge in month twenty-two of a two-year window is already in a compressed position. Section 766.104(2) allows a petition to the clerk for an automatic 90-day extension of the limitations period to complete the investigation, and in delayed-discovery cases that extension is frequently the difference between a filed claim and a barred one.

For that reason, our Miami surgical error lawyers generally start the records request and the expert review in parallel rather than in sequence. Waiting for a complete chart before engaging an expert is the most common way a viable retained item claim runs out of calendar.

Proof in a retained item case is unusually document-driven, because the object either is or is not inside the patient and the operating room generated a contemporaneous record of the reconciliation that missed it. Accordingly, the records request in these cases reaches further than a standard malpractice request does.

The evidence that ordinarily decides these claims includes:

• The intraoperative count record. Circulating nurses document sponge, sharp, and instrument counts at defined intervals, and the entry reading "count correct" at closure becomes the single most important line in the chart once an object is later found.
• The count discrepancy radiograph. When a count does not reconcile, standard practice calls for an intraoperative film before the patient leaves the room, and the presence or absence of that film speaks directly to whether the discrepancy was recognized at all.
• Radiopaque markers and detection technology. Surgical sponges carry an X-ray detectable thread, and many facilities also use radiofrequency-tagged sponges or barcode scanning, so the question becomes whether the available technology was deployed and documented.
• Post-discharge imaging. A retained sponge often presents on later CT as a mass with a characteristic appearance, sometimes described as a gossypiboma or textiloma, and the radiology studies that missed it matter as much as the one that finally identified it.
• The explanted object itself. Preserve it. Manufacturer markings, lot information, and the physical condition of the item support attribution to a specific procedure and a specific interval inside the body.
• The operative and pathology reports. The operative note describes what was placed and what was removed, and pathology from the removal surgery documents the tissue reaction that helps establish both duration and harm.
• The electronic record audit trail. Timestamps, authorship, and amendments are discoverable, and a count entry modified after the object surfaced is a materially different document than one entered contemporaneously.

Note that Florida also gives patients a constitutional right of access to records of adverse medical incidents under Amendment 7, Article X, Section 25 of the Florida Constitution. Facilities frequently contest the scope of those requests, so counsel typically pursues them early and in writing.

All of these documents answer one question from different angles: whether the team knew, or should have known, that something was missing before the wound was closed. The same intraoperative-record discipline governs other operating room claims, including the anesthesia awareness during surgery cases where the depth-of-anesthesia documentation carries the proof.

The general rule appears at Florida Statute § 95.11(5)(c): a medical malpractice action must be commenced within two years from the time the incident occurred, or within two years from the time the incident was discovered or should have been discovered with the exercise of due diligence. Confirm the current subsection numbering and your specific dates with counsel, since the legislature has reorganized § 95.11 in recent years.

Two outer limits sit behind that two-year window. In no event may the action be commenced more than four years after the incident, except that the period extends to seven years where fraud, concealment, or intentional misrepresentation of fact prevented discovery of the injury.

A narrow exception applies to children. The four-year repose period does not bar an action brought on behalf of a minor on or before that child's eighth birthday, though the exception does not enlarge the two-year discovery period itself.

Retained item cases are the paradigm setting for the discovery rule, because the injury is by definition hidden from the patient. Florida law generally starts the clock when the patient knows of the injury and of a reasonable possibility that it resulted from medical negligence rather than at the first vague symptom — confirm with counsel how that standard applies to your timeline.

What follows practically is that documenting when you learned about the object matters as much as documenting when it was left. Save the imaging report, the referral note, and the date you were told, because those records anchor the accrual argument if the defense contends you should have known sooner.

Be aware that delay is never neutral here. Where a four-year or seven-year outer limit is in play, the investigation, the expert review, and the notice of intent all have to fit inside whatever time remains, and this same deadline pressure shapes the diagnostic claims we handle as well, including missed heart attack in the ER cases.

If you have unexplained pain, recurrent infection, a palpable mass, or a bowel obstruction after surgery, the sequence below protects both your health and the evidence. Here is a list of the steps you may want to consider:

• Get imaging and a clinical opinion first. Diagnosis comes before any legal question, and a treating physician outside the original surgical group can order the study without the awkwardness of second-guessing a colleague.
• Request the complete record, not a discharge summary. Ask specifically for the operative report, the intraoperative nursing record including count sheets, all imaging and radiology reports, and the anesthesia record.
• Preserve the object if it is removed. Ask in advance, in writing, that the explanted item be retained and photographed rather than discarded as surgical waste.
• Write the timeline while it is fresh. Record the dates of each procedure, each symptom, each visit, and the moment you were told an object was found.
• Do not sign a release. Facilities sometimes offer to write off charges in exchange for a release of claims, and that document can extinguish rights worth substantially more.
• Speak with counsel before the window narrows. Pre-suit investigation and expert corroboration take time that a two-year clock does not always leave.

All of the above serves one goal: preserving the ability to answer, with documents rather than recollection, what happened in that operating room. Have you or a loved one had an object found inside you after a surgery in Miami-Dade or Broward County?
