Medical Consent for a Grandchild in Massachusetts: What Caregivers Need

You Need More Than an Insurance Card

Having a child's MassHealth card or private insurance information does not give you the legal right to consent to their medical treatment. In Massachusetts, a caregiver needs a properly executed Caregiver Authorization Affidavit under M.G.L. c. 201F to consent to healthcare on behalf of a minor. Without it, doctors, dentists, and hospitals can — and often do — refuse to treat the child except in an emergency.

What the Affidavit Covers

The healthcare authority granted under M.G.L. c. 201F is broad. It includes:

• Routine checkups, wellness visits, and diagnostic testing
• Dental exams, cleanings, fillings, and extractions
• Immunizations and vaccinations
• Prescription medications
• Mental health consultations and outpatient therapy
• Surgical procedures recommended by the treating surgeon or other healthcare professional

The affidavit also gives you the right to access the child's medical and dental records, receive billing information, and sign school nursing forms so the school nurse can administer prescribed medications like EpiPens or asthma inhalers during the school day.

What the Affidavit Does Not Cover

The parent can write specific restrictions directly into the affidavit — for example, prohibiting the caregiver from consenting to elective surgery or certain mental health medications. The affidavit also cannot override court orders. If a judge has ordered specific medical limitations, those take precedence.

Extraordinary interventions prohibited by statute — such as sterilization — fall outside the affidavit's scope entirely.

What to Bring to the First Appointment

When you take the child to a new doctor or dentist, bring:

1. Your government-issued photo ID
2. A printed copy of the executed Caregiver Authorization Affidavit
3. The child's MassHealth or private insurance card
4. Any available health records from previous providers

The doctor's office will make a copy of the affidavit for their file. Under M.G.L. c. 201F, Section 3, you have the legal right to request, inspect, and obtain copies of the child's medical and dental records, and to authorize billing disclosures.

MassHealth and Insurance Enrollment

Relative caregivers can complete and sign MassHealth applications on the child's behalf using the affidavit. A significant benefit: eligibility for "child-only" MassHealth coverage is calculated based on the child's own income and assets, not the caregiver's household income. A child with little or no income may qualify, but eligibility depends on the child's financial circumstances and MassHealth's rules.

If a Doctor or Hospital Refuses

If a medical office rejects your affidavit, follow the same structured escalation that works for schools: present the statute, ask for a written explanation, and escalate to the patient advocate, chief medical officer, or legal risk management department. For insurance barriers, contact the MassHealth Member Services Ombudsman.

The Massachusetts School and Medical Consent Guide covers first-appointment preparation, pharmacy pickup protocols, MassHealth enrollment, and escalation scripts for clinical refusals — including the statutory citations to reference.
