How long do I have to file a medical malpractice claim in Ohio?

Ohio has one of the shortest medical malpractice statutes of limitations in the country: 1 year from when you discovered (or should have discovered) the injury and its connection to medical negligence (ORC § 2305.113). There is also a 4-year absolute repose period — no claim can be brought more than 4 years after the negligent act, regardless of when discovered (except for fraud or concealment). The 1-year SOL is tolled for 180 days if you send the pre-suit notice to the defendant before the SOL expires — effectively giving you 1 year and 180 days from discovery if you send the notice promptly. For minors: the SOL tolls until age 18, but the 4-year repose is not tolled for minors in all circumstances — a child injured by malpractice near birth may have repose issues by age 4 before the SOL even starts running. Given Ohio's short SOL, if you suspect malpractice, consult an attorney immediately — the 1-year clock runs fast.

What is the 180-day pre-suit notice in Ohio medical malpractice?

Before filing a medical malpractice lawsuit in Ohio, you must serve written notice on each defendant healthcare provider at least 180 days before filing (ORC § 2305.113(B)). The notice should include: copies of relevant medical records; a description of the claim; and if available, an expert's written opinion about the malpractice. The 180-day period serves as a pre-suit investigation window — the defendant can investigate, obtain their own expert, and potentially resolve the claim without litigation. Critically, sending the notice tolls (pauses) the 1-year SOL for 180 days. This means: if you discover malpractice with 3 months left on your SOL, sending the notice immediately pauses the SOL and gives you 180 more days to gather expert opinions and prepare the complaint. Without the notice toll, you might run out of time. Sending the 180-day notice as soon as malpractice is suspected — well before the SOL expires — is the standard practice.

Is there a cap on what I can recover in an Ohio medical malpractice case?

Yes. Ohio's non-economic damages cap (ORC § 2323.43) applies to malpractice cases: $250,000 or 3× your economic damages (medical bills, lost income), whichever is higher — with an absolute maximum of $350,000 per plaintiff and $500,000 per occurrence if multiple plaintiffs are involved. The cap does NOT apply to: permanent and substantial physical deformity; loss of use of a limb; loss of a bodily organ system. So a malpractice victim who loses a limb through negligence, or is left paraplegic, is exempt from the cap. But a malpractice victim with significant pain, prolonged recovery, and moderate functional limitation that doesn't constitute permanent substantial deformity faces the $250,000–$350,000 non-economic cap. Ohio's combination of the short SOL, the 180-day pre-suit notice, and the non-economic damages cap makes it one of the harder malpractice environments for injured patients compared to uncapped states like New York or Pennsylvania.

What does the Ohio medical malpractice affidavit of merit require?

ORC § 2323.41 requires an affidavit of merit to be filed simultaneously with the complaint in any medical malpractice action. The affidavit must be from a licensed physician (or other appropriate health professional) who: is actively practicing or has recently been actively practicing in the same or substantially similar specialty as the defendant; has practical knowledge of the applicable standard of care; reviewed the medical records; and based on that review, attests that there is a reasonable basis for maintaining the action — i.e., the defendant deviated from the applicable standard of care. If an attorney cannot obtain the affidavit before the complaint is due, they can file a motion for a 90-day extension at the time of filing the complaint. Failing to file the affidavit and failing to seek an extension results in mandatory dismissal. Ohio's affidavit requirement ensures expert review before any malpractice lawsuit can proceed — it filters out claims that no qualified physician would support.

My Ohio doctor left something inside me after surgery. Does the repose period apply?

The 4-year repose period under ORC § 2305.113 generally applies, but Ohio has a specific exception for foreign objects. If a foreign object is negligently left in a patient's body, the 1-year SOL runs from when the patient discovers (or should have discovered) the foreign object — and the 4-year repose may be tolled during the period of fraudulent concealment. In practice, Ohio courts have recognized that the foreign object scenario is exactly the kind of case where the ordinary repose period would be inequitable because the patient had no way to know of the object's presence. The discovery rule is central: if you reasonably couldn't have known the object was there until it was found through imaging or symptoms, the 1-year SOL runs from discovery of the object. Send the 180-day pre-suit notice as soon as you discover the object — this preserves your SOL while you gather expert support.

Ohio Medical Malpractice — Key Facts

Statute of limitations: 1 year from discovery (ORC § 2305.113) — one of the shortest in the country
Non-economic damages cap: $250,000 or 3× economic damages (max $350,000 per plaintiff) for most malpractice cases
180-day notice: written notice must be given to potential defendants 180 days before filing suit
Expert affidavit: must be filed with the complaint — ORC § 2323.41

Ohio's medical malpractice law is among the most defendant-favorable in the country in several respects. The 1-year statute of limitations (with 4-year repose) is one of the shortest, giving injured patients less time to identify malpractice, retain a lawyer, and file suit. The 180-day pre-suit notice requirement effectively extends the filing deadline to 1 year and 180 days but requires advance planning. Ohio's non-economic damages cap — already applicable to general torts — applies with the same limits in malpractice cases.

Ohio's 1-Year Medical Malpractice SOL

ORC § 2305.113 requires medical malpractice claims to be filed within 1 year from the date the cause of action accrues — which Ohio courts define as when the patient knew or should have known of the injury and its connection to medical treatment. Ohio also has a 4-year statute of repose: no claim can be brought more than 4 years after the date of the alleged malpractice, regardless of when discovered (except for fraud or concealment, which can toll the repose). The 1-year SOL is tolled by the 180-day pre-suit notice: if the notice is sent before the SOL expires, the statute is tolled for 180 days. For minors: the SOL is tolled until the child's 18th birthday (but the 4-year repose is not tolled for minors — a child injured at age 14 has until age 18 plus 1 year to file, but the 4-year repose from the date of the act may bar the claim).

180-Day Pre-Suit Notice Requirement

Before filing a medical malpractice lawsuit, the plaintiff must give 180 days' notice to each defendant healthcare provider (ORC § 2305.113(B)). The notice must include: the medical records related to the alleged malpractice; a description of the claim; and if available, an expert opinion. The 180-day notice tolls the SOL — if the SOL is about to expire, sending the notice preserves the filing right for an additional 180 days. After the 180-day period, the lawsuit can be filed. The notice requirement allows healthcare providers to evaluate the claim, obtain their own experts, and potentially settle without litigation. Missing the notice requirement does not automatically bar the claim in all circumstances, but failing to provide notice and then filing immediately may be used against the plaintiff.

Ohio's Non-Economic Damages Cap in Malpractice

Ohio's non-economic damages cap from HB 350 (ORC § 2323.43) applies to medical malpractice: $250,000 or 3× economic damages (whichever is higher), with an absolute maximum of $350,000 per plaintiff / $500,000 per occurrence for multiple plaintiffs. The catastrophic injury exception (permanent and substantial physical deformity, loss of use of a limb, loss of a bodily organ system) exempts the claim from the cap — making the cap inapplicable in the most severe cases. Ohio's combination of 1-year SOL, 4-year repose, and the non-economic cap makes Ohio's malpractice environment significantly more restrictive for injured patients than most states.

Certificate of Merit / Expert Affidavit

Ohio requires an affidavit of merit to be filed with the complaint in medical malpractice cases (ORC § 2323.41). The affidavit must be from a qualified medical expert (licensed in Ohio or another state with active clinical practice in the relevant specialty within the past 5 years) stating: the expert reviewed the materials; the expert is familiar with the applicable standard of care; and in the expert's opinion the standard of care was not met. Failure to file the affidavit with the complaint subjects the case to dismissal. Ohio does allow a 90-day extension if the plaintiff's attorney submits a motion at the time of filing explaining the need for additional time to obtain the expert's affidavit.
