N.M. Stat. § 27-5-12
Payment of claims.
A. A hospital, ambulance service or health care provider filing a claim with the
county shall:
(1)
file the claim with the county in which the indigent patient is domiciled;
(2)
file the claim for each patient separately, with an itemized detail of the total
cost; and
(3)
file with the claim a verified statement of qualification for ambulance
service, indigent hospital care or care from a health care provider signed by the patient
or by the parent or person having custody of the patient to the effect that the patient
qualifies under the provisions of the Indigent Hospital and County Health Care Act as an
indigent patient and is unable to pay the cost for the care administered and listing all
assets owned by the patient or any person legally responsible for the patient's care. The
statement shall constitute an oath of the person signing it, and any false statements in
the statement made knowingly constitute a felony.
B. A hospital, ambulance service or health care provider that has contracted with a
county for provision of health care services shall provide evidence of health care
services rendered for payment for services in accordance with the procedures specified
in the contract.
