Special Monthly Compensation (SMC): Which Letter Fits You?

A regular rating tops out at 100%. Some losses, like the use of a hand or your eyesight, or needing someone's help every day, cost more than that scale pays for. SMC adds to the basic rate or replaces it. VA's SMC rate tables list each level's monthly amount.

VA's rules say its job is "to render a decision which grants every benefit that can be supported in law" (38 C.F.R. § 3.103(a)). So VA should consider SMC when your records support it, even if you never asked by name. That doesn't always happen, so it's worth checking.

• K: Loss or loss of use of one hand, one foot, a creative organ or both buttocks; blindness in one eye with light perception only; deafness in both ears; complete loss of speech; certain breast tissue loss or radiation treatment for women Veterans (§ 1114(k); § 3.350(a)).
• L: Loss or loss of use of both feet, or of one hand and one foot; blindness in both eyes at 5/200 or less; being permanently bedridden; or needing regular aid and attendance (§ 1114(l); § 3.350(b)).
• M: Loss or loss of use of both hands; loss of both legs, or an arm and a leg, at levels that prevent natural knee or elbow action with a prosthesis; blindness in both eyes with light perception only (§ 1114(m); § 3.350(c)).
• N: Loss of use of both arms at a level that prevents natural elbow action; leg or arm amputations that prevent using a prosthesis; loss of both eyes, or blindness without light perception in both eyes (§ 1114(n); § 3.350(d)).
• O: Two or more separate conditions that each qualify for L, M or N; paraplegia with loss of bowel and bladder control; certain combinations of severe deafness and blindness (§ 1114(o); § 3.350(e)).
• P and the half steps: A next-higher or in-between rate when your disabilities go beyond one level's requirements (§ 1114(p); § 3.350(f)).
• R (R.1 and R.2): Aid and attendance on top of the highest rates, and a higher level of daily in-home care (§ 1114(r); §§ 3.350(h), 3.352).
• S: A single disability rated 100%, plus either separate disabilities ratable at 60% or more, or being permanently housebound (§ 1114(s); § 3.350(i)).

There is no new Q award. Congress repealed § 1114(q) in 1968, and VA's rate page says it hasn't awarded that rate since August 19, 1968.

Many letters turn on "loss of use," not amputation. For a hand or foot, VA asks whether "no effective function remains other than that which would be equally well served by an amputation stump" with a prosthesis (§ 3.350(a)(2)). The rule's examples are grasping for a hand and balance and propulsion for a foot. VA looks at what you can actually do, so records that describe function matter.

• K is an add-on. VA's rate page says K is added to any rating from 0% to 100% and to other SMC rates except O, Q and R, with one to three K awards; the law caps the total. For rates effective December 1, 2025, K is $139.87 a month.
• L through O replace the basic rate, each with its own amount.
• Half steps and full steps. Under § 3.350(f), a separate disability "independently ratable at 50 percent or more" can add a half step. One ratable at 100% "apart from any consideration of individual unemployability" can add a full step, as can loss of use of three extremities.
• R sits on top. Under § 1114(r), it is only for Veterans already paid at the O rate, the top P rate, or the half step between N and O plus K, who also need regular aid and attendance. R.2 adds a higher level of daily care that a licensed health professional provides or regularly supervises, without which you would need a hospital, nursing home or similar care (§ 3.352(b)).
• S stands apart. It starts with a single disability rated 100%, not a combined 100% built from several conditions (§ 3.350(i)). "Housebound" means you are substantially confined to your home and its immediate premises because of service-connected disabilities, and that is reasonably certain to last for life.

Aid and attendance comes up at L and again at R. Under 38 C.F.R. § 3.352(a), VA weighs whether you can dress, keep clean, feed yourself and use the toilet on your own, whether a prosthetic needs frequent adjustment, and whether you need regular help to stay safe from everyday hazards. You don't need every item. "Bedridden" is narrow: a condition that actually requires you to stay in bed, not rest a doctor prescribes for recovery.

• Find the SMC lines. A decision on SMC usually lists it as its own issue and names the subsection, such as § 1114(k). How to Read Your VA Decision Letter shows where issues appear.
• Compare it with your records. If your records fit a letter above and the decision says nothing about SMC, VA may not have considered it.
• Pick a next step. If VA decided SMC and you disagree, you generally have one year to choose a review lane; HLR, Supplemental Claim, or Board Appeal? compares them. If VA never decided SMC, you can ask it to.
