N.H. Rev. Stat. § 126-A:44
The commissioner may charge less than the uniform rate when the commissioner finds a patient or any relative chargeable therewith is able to bear only a portion of the expense incident to the patient's care, treatment, and maintenance at such institution, or care, treatment, and maintenance furnished at the direction of the commissioner. In establishing such charge, the commissioner shall consider the report, investigation and recommended charge of the office of reimbursements. The established charge shall be billed by the superintendent of such institution. The office of reimbursements shall make further recommendations as provided in this section where conditions affecting the ability to pay of persons legally chargeable for the support of the patient or resident have changed. The establishment of a partial rate as provided herein shall not preclude the collection of the balance between the partial rate and the full rate from an estate of the patient or resident or the estate of those legally chargeable as provided in RSA 126-A:37.
