Statute of Limitations for Medical Malpractice in Colorado

Overview

Run this scenario in DocketMath using the Statute Of Limitations calculator.

Colorado generally sets a 2-year statute of limitations for most medical malpractice claims under C.R.S. § 13-80-106(1). Practically, that means an injured patient (or authorized representative) must typically file a lawsuit within 2 years after the claim “accrues.”

For many cases, “accrual” is tied to when the injury was discovered or when it should have been discovered through reasonable diligence. So two cases with the same treatment date can still have different deadlines if the discovery timing differs.

DocketMath’s statute-of-limitations calculator can help you model timing scenarios—for example, how an earlier vs. later discovery date changes the last day to file. This article is meant to be practical and educational, not legal advice; your deadlines can depend on the specific facts and procedural posture of your case.

Limitation period

The baseline medical malpractice limitations period in Colorado is 2 years. The primary statute is C.R.S. § 13-80-106(1), which covers actions for injury “upon the claim that a physician or other health care provider has failed to use reasonable care.”

In real-world timing disputes, people usually run into two related concepts:

• Discovery/accrual timing: When the claim accrues can depend on when the injury was discovered or reasonably should have been discovered.
• Outside/absolute “hard-stop” concepts: Some situations can impose an outer limit that prevents filing long after the treatment event, even if discovery occurred later.

Because those concepts can interact, the actual calendar deadline may change depending on the dates and facts you enter.

What inputs usually matter in Colorado medical malpractice timing

When you use DocketMath, you’ll typically want to map your facts to dates such as:

• Date of treatment / alleged negligent act (often the procedure date)
• Date of injury discovery (when the patient learned of the injury)
• Date the injury should have been discovered (when a reasonable person would have known)
• Any tolling trigger (for example, certain disabilities)

Then the tool helps translate those date assumptions into a likely limitations timeline under the relevant framework.

How the output changes (what to watch for)

As you change your inputs, the “last day to file” can move because:

• Earlier discovery date → a shorter window to sue.
• Later discovery date → a longer window to sue (assuming no outside limit applies).
• Tolling/disability trigger → the deadline may move outward by an amount permitted by Colorado’s tolling rules (when applicable).

If you’re evaluating more than one plausible timeline (common when medical records are unclear or discovery is disputed), running multiple scenarios can help you understand the range of possible deadlines.

Key exceptions

Colorado medical malpractice limitations timing isn’t always a simple “2 years from treatment.” Multiple doctrines and exceptions can affect whether the deadline is extended, tolled, or governed by a different accrual analysis.

1) Minors and certain incapacity tolling

Colorado law includes tolling for claims brought by persons under disability—often discussed in practical terms as minority. If the patient was a minor (or otherwise within a tolling category) during the relevant period, the filing deadline may be extended beyond the default 2-year period.

How this affects your calculation:

• Tolling may delay when the limitations clock effectively starts (or suspend it) for a statutorily defined period.

2) Accrual and discovery timing disputes

Even with the “2-year” label, the most common dispute can be when the claim accrued for limitations purposes.

In practice, “accrual” may depend on:

• when the patient actually discovered the injury, and/or
• when the injury should have been discovered through reasonable diligence,
• and (in many cases) when the patient could reasonably connect the injury to the medical care.

How this affects your calculation:

• A later discovery date can push the deadline later.
• An earlier should-have-discovered date can shorten it.

3) Procedural timing issues (within the limitations framework)

The core question is usually statutory timing, but litigation can involve procedural realities that raise timing questions—for example, whether adding or changing parties or claims later creates limitations concerns.

4) Outside-limit concepts (when “hard stop” arguments matter)

Colorado’s statutes and related doctrines can sometimes impose an absolute outer limit that bars claims after a certain point—even if discovery occurred later.

How this affects your calculation:

• If an outside limit applies, the “latest filing date” may be earlier than what you’d calculate using a purely discovery-based 2-year approach.

Statute citation

The key Colorado medical malpractice limitations citation is:

• C.R.S. § 13-80-106(1) — 2-year limitation for actions alleging failure by a physician or other health care provider to use reasonable care.

Related tolling and timing rules may appear elsewhere in C.R.S. § 13-80 and related provisions, including rules addressing disability (such as minority).

How to run the calculation (practical steps)

1. Open the DocketMath statute calculator: /tools/statute-of-limitations
2. Select Colorado (US-CO) as your jurisdiction.
3. Enter the key dates that best match your facts:

   • Date of treatment (alleged negligent act)
   • Discovery date (when the injury was discovered)
   • If you’re comparing alternatives, should-have-discovered date
   • Any tolling facts (such as minority/disability, where applicable)
4. Review:

   • The calculated limitations period
   • The estimated last filing date
   • Any notes about which date assumption controls in the model

Understanding the output

DocketMath’s results generally reflect a baseline 2-year structure under C.R.S. § 13-80-106(1), then adjust based on:

• your chosen accrual/discovery assumptions, and
• any tolling/exception inputs that fit the tool’s framework.

If your dates are uncertain, run multiple scenarios—for example:

• Scenario A: discovery on the earliest documented date
• Scenario B: discovery on a later date supported by records
• Scenario C: discovery adjusted by a tolling trigger (if applicable)
