How to Find a Cause of Death in Iowa (2026 Guide)

Iowa records a cause of death on the medical certification portion of the death certificate, and for sudden, violent, or unexplained deaths in an autopsy report. The cause of death is publicly accessible through county-held death records under Iowa's open-records law, but a certified state copy and a full autopsy report are released only to eligible relatives.

How Do You Find Someone's Cause of Death in Iowa?

You find a cause of death in Iowa by locating the record that carries the medical certification. The clearest public route is the death certificate held by the county registrar, which any member of the public may inspect and copy under Iowa's open-records law.

The cause of death sits in the medical certification section of that certificate, signed by the physician, physician assistant, or advanced registered nurse practitioner in charge of the patient's care, or by the medical examiner. For a death that was sudden, violent, or unexplained, the fuller explanation is in the medical examiner's autopsy report.

Practical routes the public uses include the obituary or a newspaper account, the death certificate itself, the autopsy report (for eligible family), and older or genealogy records once they become public. None of these are the same as a certified state copy, which is restricted.

Is the Cause of Death Public in Iowa?

It depends on which office holds the record. Iowa Code 144.43(3)(a) provides that a record of death, other than a fetal death, in the custody of a county registrar may be inspected and copied as of right under chapter 22, Iowa's open-records law. Because that record includes the cause of death, the cause is publicly accessible at the county level with no waiting period and no eligibility test.

A certified copy issued by the Iowa Department of Health and Human Services state office is different. It is released only to people with a recognized relationship to the deceased or a legal interest in the record, so the cause of death on a certified state copy is not open to the general public.

So the same death can be open at the county registrar and gated at the state registrar. This tracks the broader rule that Iowa death records follow a two-track system, part of how death records work across states in our Death Records by State hub.

Where the Cause of Death Is Recorded

The cause of death appears in two main places: the death certificate and, when one is performed, the autopsy report. They serve different purposes.

The Death Certificate

Every Iowa death certificate contains a medical certification of the cause of death. Unless there is a nonnatural cause of death, it is completed and signed by the physician, physician assistant, or advanced registered nurse practitioner in charge of the patient's care (Iowa Code 144.28(1)(b)). A physician assistant or advanced registered nurse practitioner who signs must be licensed in Iowa and must have been in charge of the deceased patient's care. For a death referred to the medical examiner, the examiner completes the cause and manner of death.

Iowa law allows a correction to the medical certification of cause of death within twelve months of the date of death if supporting evidence is presented to the state registrar. After twelve months, a change requires a court order. This is why a certificate's stated cause can be amended in the months after a death.

The Autopsy Report

When a county medical examiner orders an autopsy, the resulting report gives a detailed cause and manner of death. The Office of the State Medical Examiner notes that final results and the completed autopsy report may take 60 to 90 days.

The autopsy report is far more detailed than the one-line cause on the certificate, but access to it is more restricted.

How to Request Records That Show the Cause of Death

Your options depend on who you are and how much detail you need.

For the death certificate at the county level, you can inspect or copy the record under the open-records law without proving a relationship. For a certified state copy, you apply to the Iowa Department of Health and Human Services Bureau of Health Statistics, and you must be the spouse, a child, a legal parent, a grandparent, a grandchild, a sibling, or the legal representative or guardian of the deceased.

A certified copy costs $15.00 for each copy, which covers the record search and is not refunded if no record is found. Mailed applications must be notarized and include a copy of your government-issued photo ID.

For the autopsy report, the Office of the State Medical Examiner releases the full report only to the legal next of kin, on a notarized written request, at no charge. The request must include your full name, your relationship to the deceased, and your contact information.

Confirm current requirements with the Iowa Department of Health and Human Services Bureau of Health Statistics, the relevant county registrar, or the Office of the State Medical Examiner before you rely on them.

Finding the Cause of Death for Older or Historical Deaths

For older Iowa deaths, the record may already be public at the State Archives. A death record held by the State Archives becomes a public record once it is at least 50 years old under Iowa Code 144.43(3)(b).

Once a death record is in that public window, anyone may obtain it, including the cause of death shown on the certificate. The State Historical Society of Iowa holds historical vital records and can help with genealogy-era research.

For confirming only the fact of a death rather than its cause, the Social Security Death Index is a useful starting point. It lists the name, dates of birth and death, and last residence drawn from Social Security records, but it never includes a cause of death.
