[(q) Repealed. Pub. L. 90–493, § 4(a), Aug. 19, 1968, 82 Stat. 809.]

(r) Subject to section 5503 (c) of this title, if any veteran, otherwise entitled to compensation authorized under subsection (o) of this section, at the maximum rate authorized under subsection (p) of this section, or at the intermediate rate authorized between the rates authorized under subsections (n) and (o) of this section and at the rate authorized under subsection (k) of this section, is in need of regular aid and attendance, then, in addition to such compensation

(1) the veteran shall be paid a monthly aid and attendance allowance at the rate of $1,851; or

(2) if the veteran, in addition to such need for regular aid and attendance, is in need of a higher level of care, such veteran shall be paid a monthly aid and attendance allowance at the rate of $$2,757,^[1] in lieu of the allowance authorized in clause (1) of this subsection, if the Secretary finds that the veteran, in the absence of the provision of such care, would require hospitalization, nursing home care, or other residential institutional care.

For the purposes of clause (2) of this subsection, need for a higher level of care shall be considered to be need for personal health-care services provided on a daily basis in the veterans home by a person who is licensed to provide such services or who provides such services under the regular supervision of a licensed health-care professional. The existence of the need for such care shall be determined by a physician employed by the Department or, in areas where no such physician is available, by a physician carrying out such function under contract or fee arrangement based on an examination by such physician. For the purposes of section 1134 of this title, such allowance shall be considered as additional compensation payable for disability.

(s) If the veteran has a service-connected disability rated as total, and

(1) has additional service-connected disability or disabilities independently ratable at 60 percent or more, or,

(2) by reason of such veterans service-connected disability or disabilities, is permanently housebound, then the monthly compensation shall be $2,766. For the purpose of this subsection, the requirement of permanently housebound will be considered to have been met when the veteran is substantially confined to such veterans house (ward or clinical areas, if institutionalized) or immediate premises due to a service-connected disability or disabilities which it is reasonably certain will remain throughout such veterans lifetime.

[1] So in original.

(F) notwithstanding the other provisions of this paragraph, the monthly amount payable on account of each child who has attained the age of eighteen years and who is pursuing a course of instruction at an approved educational institution shall be $222 for a totally disabled veteran and proportionate amounts for partially disabled veterans in accordance with paragraph (2) of this section.

(2) If and while rated partially disabled, but not less than 30 percent, in an amount having the same ratio to the amount specified in paragraph (1) of this section as the degree of disability bears to total disability. The amounts payable under this paragraph, if not a multiple of $1, shall be rounded down to the nearest dollar.
