SMC-K: Loss or Loss of Use of an Anatomical Part

What Is SMC-K?

SMC-K is an additional monthly payment, currently $140.16/month, paid on top of your regular schedular compensation when you have suffered the anatomical loss or loss of use of a specific body part listed in 38 CFR § 3.350(a).

Unlike SMC-L through SMC-T (which replace your schedular rate with a higher monthly amount), SMC-K stacks on top of your existing pay. Veterans at any rating from 0% to 100% can receive SMC-K if they qualify.

The 19 Qualifying Categories

38 CFR § 3.350(a) lists the qualifying anatomical losses or losses of use:

The list above shows the most common categories. The full regulation also covers loss of use of mastectomy on the female anatomy, and a handful of less-common scenarios. Read 38 CFR § 3.350(a) directly for the comprehensive list.

"Loss of Use" Standard

"Loss of use" of a hand or foot is defined in 38 CFR § 3.350(a)(2):

"Loss of use of a hand or a foot will be held to exist when no effective function remains other than that which would be equally well served by an amputation stump at the site of election below elbow or knee with use of a suitable prosthetic appliance."

The legal test is functional, not anatomical. A foot that is technically intact but completely unable to bear weight or perform any locomotor function may satisfy "loss of use." Severe peripheral neuropathy, end-stage drop foot, or complete tarsal-tunnel syndrome commonly meet this standard.

For a creative organ, "loss of use" means the organ cannot perform its reproductive function. Sterility from service-connected radiation exposure, chemotherapy, or surgical removal qualifies even when the organ is anatomically present.

Stacking Multiple SMC-K Awards

SMC-K awards stack: each separate qualifying loss adds another $140.16/month. Two losses = $280.32. Three = $420.48.

Example: a veteran with service-connected diabetes who has lost erectile function (SMC-K #1) and has loss of use of one foot from peripheral neuropathy (SMC-K #2) and is sterile from chemotherapy for service-connected cancer (SMC-K #3) receives 3 × SMC-K, an additional $420.48/month on top of their schedular rate.

2026 Rate

SMC-K's 2026 monthly add-on is $140.16, set by VA each December 1 alongside COLA-adjusted compensation rates. The rate has no dependent supplements, it's a flat add-on regardless of family composition.

Per loss, the rate stacks linearly. Two qualifying losses = $280.32. Five = $700.80. There is no maximum number of stacked SMC-K payments, though large stacks usually trigger eligibility for higher SMC tiers.

Evidence That Wins

SMC-K evidence depends on the category claimed:

• Anatomical loss (amputation, surgical removal): operative reports, post-op imaging, surgical pathology. Usually undisputed.
• Loss of use of foot/hand: EMG/nerve conduction studies, orthopedic exam findings of "no effective function," videotape evidence of weight-bearing or grip limitations.
• Creative organ / loss of erectile function: urology workup, hormone panels, treatment records (PDE-5 inhibitors documented as ineffective). The bar is lower than commonly assumed, treatment failure on standard medications often suffices.
• Sterility: semen analysis (azoospermia / severely abnormal counts), gynecologic exam findings of premature ovarian failure, oncology records linking sterility to service-connected treatment.
• Blindness in one eye: ophthalmology Snellen acuity readings (5/200 or worse) or field-defect measurements.
• Deafness: audiologic testing showing absence of both air and bone conduction.
• Aphonia: ENT/laryngology records, speech-pathology evaluation, video evidence of attempted phonation.

SMC-K vs SMC-L and Higher

The two coexist. A veteran with regular A&A need (SMC-L) plus loss of erectile function (SMC-K) receives the SMC-L rate plus the SMC-K add-on.

How to File

1. File VA Form 21-526EZ. SMC-K can be claimed on the same disability claim that establishes the underlying condition (e.g., file diabetes + claim SMC-K for loss of erectile function as secondary).
2. Document the qualifying loss. Operative reports, EMG/NCS, audiology, ophthalmology, urology workup, depending on category.
3. Establish service connection of the underlying cause. SMC-K only pays for losses caused by service-connected conditions. The cancer, the diabetes, the trauma, must itself be service-connected.
4. Identify all SMC-K losses on the claim. If multiple categories apply, list each one. VA does not infer additional SMC-K losses, claim them explicitly.

Common Mistakes

• Not claiming SMC-K with the underlying condition. File the disability claim and the SMC-K claim together. Claiming SMC-K years later loses back pay.
• Missing erectile-dysfunction SMC-K secondary to diabetes / PTSD / SSRI medication. Treatment failure on standard meds satisfies "loss of use" and the claim is widely under-filed.
• Stopping at one SMC-K when multiple categories apply. Each separate loss adds another $140.16. Audit the full § 3.350(a) list against your conditions.
• Confusing SMC-K with SMC-L. SMC-K is the add-on. SMC-L is the replacement rate. Different rules, different amounts.
• Not factoring SMC-K into the higher-tier ladder. Multiple SMC-K losses combined with high schedular ratings may bump you to SMC-O+ under the intermediate-rate rules.
