Colorado Euthanasia Law: Eligibility, Request Process, and Limits

Euthanasia is illegal in Colorado. What state law does allow, under the End-of-Life Options Act, is medical aid in dying: a terminally ill adult who meets strict criteria can request a prescription and take the medication themselves. The distinction matters. A physician who directly administers a lethal drug to a patient is not protected by the Colorado euthanasia law framework and could face homicide charges. The law protects only self-administration by a qualified patient who has gone through the full request process.¹

Voters passed the law as Proposition 106 in 2016, and the General Assembly expanded access through Senate Bill 24-068 in 2024.²

What Counts as Legal and What Doesn’t

The dividing line is who puts the medication into the patient’s body. The patient must voluntarily swallow or otherwise ingest the drug. If anyone else administers it, that act falls outside the law and can be prosecuted as homicide or manslaughter.¹

When a patient dies after taking the medication under this process, the death certificate lists the underlying terminal illness as the cause of death. The death is not legally classified as suicide or homicide. That classification has downstream effects for life insurance claims, estate matters, and public health records.³

Who Qualifies

A patient must meet every one of the following before any provider will write a prescription.

Age and Colorado Residency

The patient must be at least 18 and a Colorado resident. The residency requirement has stayed on the books, so people cannot travel to Colorado solely to access the law. Proof can be a Colorado driver’s license or state ID, voter registration, evidence of owning or leasing property in the state, or a Colorado income tax return for the most recent tax year.⁴

A Terminal Prognosis of Six Months or Less

Two providers, the attending and the consulting, must independently confirm the patient has a terminal illness with a prognosis of six months or less to live. The law lists no specific qualifying diseases and leaves the judgment to medicine. In practice, conditions such as advanced cancer, ALS, and end-stage organ failure commonly qualify. Serious but non-terminal conditions, such as well-managed diabetes or early-stage dementia, do not.³

Mental Capacity to Make the Decision

The patient must be able to understand the diagnosis, prognosis, available alternatives (including palliative care and hospice), and the risks and expected outcome of taking the medication. A mental health diagnosis alone does not disqualify someone; the question is whether the person can reason through the decision at the time they make it. If either the attending or consulting provider suspects impaired judgment, they must refer the patient to a licensed mental health professional, and no prescription can be written until that professional confirms capacity in writing.⁴

How the Request Process Works

The procedure is designed to confirm that the patient’s decision is consistent, informed, and voluntary.

Two Oral Requests, Seven Days Apart

The patient must make two oral requests to the attending provider. Senate Bill 24-068 shortened the gap between them to at least seven days, down from the original fifteen. If the attending provider determines the patient is unlikely to survive more than 48 hours and all other requirements are met, the waiting period can be waived.²

A Written Request With Two Witnesses

After the second oral request, the patient submits a written request that substantially follows the statutory form in Colorado Revised Statutes Section 25-48-112. The form affirms that the patient has been fully informed of diagnosis, prognosis, and alternatives, and that most deaths occur within three hours though the process may take longer.⁵

Two witnesses must sign, attesting that the patient appears mentally capable, is acting voluntarily, and is not being coerced. At least one witness must not be related to the patient by blood, marriage, civil union, or adoption; must not stand to inherit any part of the estate; and must not be an owner, operator, or employee of the healthcare facility treating the patient. Neither provider involved in the case may serve as a witness, and neither may anyone holding the patient’s power of attorney or durable medical power of attorney.⁶

The Right to Rescind

The patient can withdraw the request at any point, regardless of mental state at the time of withdrawal. The attending provider must remind the patient of this right before writing the prescription. No earlier request binds a patient who has changed their mind.⁴

Which Providers Can Be Involved

Since 2024, advanced practice registered nurses can serve in roles previously limited to physicians.² Three roles are defined by statute:

The attending provider is the physician or APRN with primary responsibility for the patient’s care. They confirm diagnosis, assess capacity, verify residency, discuss alternatives, and write the prescription if everything checks out.
The consulting provider is a second physician or APRN who independently confirms the diagnosis and prognosis in writing. They do not prescribe.
The pharmacist dispenses the medication after verifying documentation and files a form with the Colorado Department of Public Health and Environment within ten calendar days.³

No provider is required to participate. Physicians, APRNs, and healthcare facilities can decline on personal, moral, or religious grounds. Some Colorado hospitals have opted out institutionally, though a facility that does so cannot stop a patient from pursuing the process with other providers outside its walls.¹

Cost, Insurance, and Unused Medication

The law does not name a specific drug. Costs vary widely: secobarbital, a barbiturate sedative, has run over $4,000 for a lethal dose, while multi-drug compound formulations are closer to $500. The choice is a conversation between patient and provider.

Insurance coverage depends on the plan. Federal law bars Medicare and Medicaid funds from paying for any service provided to cause or assist in causing a patient’s death, including the medication itself.⁷ For private coverage, the 2024 amendments prohibit health and life insurance carriers in Colorado from denying or altering benefits based on the availability of medical aid in dying, and from steering a terminally ill patient toward requesting it as an alternative to covering treatment.²

On life insurance, Colorado law provides that after the first policy year, suicide is not a valid defense for refusing to pay a claim. Because medical aid in dying is not legally classified as suicide, claims should generally not be affected. Accidental death policies specifically are excluded from that protection.⁸

After the patient dies, anyone holding unused medication must dispose of it lawfully: either return it to the prescribing provider or use a state- or federally-approved take-back program under the federal Secure and Responsible Drug Disposal Act. Flushing it or throwing it in household trash is not permitted.⁹

Criminal Exposure for Stepping Outside the Law

Providers who follow the statute in good faith are shielded from criminal prosecution, civil liability, and professional discipline. The immunity does not cover negligence, recklessness, or intentional misconduct.¹

Outside the law’s framework, the exposure is serious. Causing someone’s death by forging or altering a medical aid-in-dying request without the patient’s authorization is a class 2 felony, with a presumptive sentence of 8 to 24 years.¹⁰¹¹ Physically helping a patient take the medication, rather than letting them self-administer, can lead to manslaughter charges under Colorado’s statute making it a class 4 felony to intentionally cause or aid another to commit suicide.¹² Family members and caregivers who want to help face real criminal risk if they act outside the procedures the law requires.

Providers who skip required steps, prescribe to a patient who does not qualify, or fail to document the process can face licensing board discipline up to loss of licensure, and criminal charges where the facts support them.
