Wisconsin Health Care Power of Attorney: What Families Need to Know

Your child turns 18 next month, and suddenly the pediatrician's office tells you they can't share lab results without written authorization. That's not a bureaucratic quirk — it's federal HIPAA law colliding with Wisconsin's age of majority. A health care power of attorney (POAHC) is one of the most practical tools for bridging that gap without going to court.

How Wisconsin's Health Care POA Works Under Chapter 155

Wisconsin's POAHC is governed by Chapter 155 of the state statutes. The document lets your adult child (the "principal") name an agent — typically a parent — to make medical decisions on their behalf under specific conditions.

The critical detail: a POAHC is a "springing" document. Your authority as agent doesn't activate the moment the form is signed. It kicks in only when two physicians (or one physician and one advanced practice clinician) personally examine the principal and sign a written finding that they lack the capacity to make their own healthcare decisions.

Until that threshold is met, the young adult makes their own medical choices. You can't override them, even as the named agent.

Who Can Execute a Health Care POA

The principal — your adult child — must have sufficient cognitive capacity to understand what they're signing at the time of execution. This is a key consideration for families navigating the turning-18 transition: if your child can grasp the concept of appointing someone to make health decisions for them, a POAHC works. If they cannot understand that concept, you may need to explore guardianship under Chapter 54 instead.

The agent can be any adult. A health care provider, a health care facility employee, or a spouse of one generally cannot be named unless that person is also the principal's relative. Most families name one or both parents. You can also name a successor agent in case the primary agent is unavailable.

The Form You Need: DHS F-00085

Wisconsin provides an official template — DHS Form F-00085 — through the Department of Health Services. You can download it directly from dhs.wisconsin.gov. Using the state form isn't technically required (a custom document works if it meets statutory requirements), but the official form is widely recognized by hospitals and clinics, which reduces institutional pushback.

The form must be signed by the principal and either notarized or witnessed by two adults. The witnesses cannot be the named agent or the principal's health care provider.

POAHC vs. HIPAA Releases: They Solve Different Problems

A common point of confusion: a HIPAA release and a POAHC are not the same thing.

A HIPAA authorization lets you access information — view medical records, receive test results, speak with providers about your child's care. But it doesn't give you any decision-making authority.

A POAHC gives you actual authority to make decisions — consent to surgery, choose treatment options, direct end-of-life care — but only when the activation threshold is met.

Most families need both. The HIPAA release handles day-to-day information sharing from the moment the form is signed. The POAHC provides a safety net for crisis situations where your child cannot direct their own care.

Pairing a POAHC With Other Planning Tools

A health care POA works well alongside Wisconsin's other less-restrictive alternatives:

• Supported Decision-Making Agreement (Chapter 52): Lets a supporter help the young adult gather information and communicate decisions. Pairs naturally with a POAHC — the SDM handles routine healthcare conversations while the POAHC covers incapacity situations.
• Financial Power of Attorney (Chapter 244): Covers the financial side — bank accounts, bills, benefit applications — which the POAHC doesn't touch.
• FERPA consent: Maintains your access to educational records after the transfer of rights at 18.

Together, these documents often provide enough legal coverage that families can avoid the cost and complexity of a formal guardianship petition.

When a POAHC Isn't Enough

A health care POA has clear limits. If your young adult routinely needs someone else to direct day-to-day medical care — not just crisis situations — the springing activation may not match their actual needs. Similarly, if they lack the cognitive capacity to execute the document in the first place, a POAHC isn't a viable option.

In those situations, a limited guardianship of the person under Chapter 54 may be necessary. Wisconsin courts are required to consider less-restrictive alternatives first under § 54.10(3)(a)4, so having attempted a POAHC (and documenting why it proved insufficient) strengthens a guardianship petition.
