Kidney stones are rated under Diagnostic Code 7508 in 38 CFR 4.115b, and the rule is short: nephrolithiasis is rated as hydronephrosis, except for recurrent stone formation requiring invasive or non-invasive procedures more than two times per year, which is 30%. That means the available percentages are 30%, 20%, 10%, or 0%, and the deciding facts are how often you have attacks of colic and how often you need a procedure. Kidney function, GFR, and creatinine do not drive the rating here. In 2026, a 30% rating pays $552.47 per month for a veteran with no dependents, 20% pays $356.66, and 10% pays $180.42.
This is a rating schedule that surprises people. Passing a stone is one of the most painful things a body can do, and veterans routinely come out of a C&P exam with 0%. The reason is mechanical, not personal, and it is worth understanding before you file.
How DC 7508 Actually Works
DC 7508 covers nephrolithiasis, ureterolithiasis, and nephrocalcinosis, so stones in the kidney, stones in the ureter, and calcium deposits in kidney tissue all land in the same place. The code itself contains only one rating level. Everything else routes to DC 7509, hydronephrosis.
The verbatim structure in 38 CFR 4.115b:
7508 Nephrolithiasis/Ureterolithiasis/Nephrocalcinosis: Rate as hydronephrosis, except for recurrent stone formation requiring invasive or non-invasive procedures more than two times/year ... 30
So a rater looks at your file and asks two questions in order:
- Did recurrent stone formation require invasive or non-invasive procedures more than two times in a year? If yes, 30%.
- If no, what do the hydronephrosis criteria give you?
"More than two times per year" means three or more procedures inside a 12 month window. Two procedures is not enough. Non-invasive counts, so extracorporeal shock wave lithotripsy (ESWL) qualifies alongside ureteroscopy, stent placement, and percutaneous nephrolithotomy. Emergency room visits for pain control, imaging, and prescriptions for tamsulosin do not count as procedures.
The Hydronephrosis Tiers (DC 7509)
This is where the lower percentages come from. Under DC 7509 in 38 CFR 4.115b:
| Rating | Criteria under DC 7509 |
|---|
| Severe | Rate as renal dysfunction under 38 CFR 4.115a instead |
| 30% | Frequent attacks of colic with infection (pyonephrosis), kidney function impaired |
| 20% | Frequent attacks of colic, requiring catheter drainage |
| 10% | Only an occasional attack of colic, not infected and not requiring catheter drainage |
Note what is missing: there is no 0% listed. When the schedule does not provide a zero percent level, 38 CFR 4.31 supplies one, and a 0% is assigned whenever the requirements for a compensable evaluation are not met. That is the provision doing most of the work on kidney stone claims.
Two words carry the weight in DC 7509. "Colic" means the acute obstructive pain of a stone moving, documented as a clinical event, not soreness in your back. "Frequent" is not defined by a number in the regulation, so raters look at the treatment record and decide. A single documented episode is not frequent. Three or four documented colic episodes in a year, with records, is a real argument.
Putting Both Codes Together
| Your situation | Likely rating |
|---|
| Three or more stone procedures (ESWL, ureteroscopy, stent, PCNL) in a 12 month period | 30% under DC 7508 |
| Frequent colic attacks with infection (pyonephrosis) and impaired kidney function | 30% under DC 7509 |
| Frequent colic attacks requiring catheter or stent drainage | 20% under DC 7509 |
| An occasional colic attack, no infection, no drainage needed | 10% under DC 7509 |
| One stone episode years ago, no recurrence, no current treatment | 0% under 38 CFR 4.31 |
| Stones plus reduced kidney function (GFR below 60 with qualifying findings) | Rate under renal dysfunction, 38 CFR 4.115a |
The November 14, 2021 Change That Cut Off the Easy 30%
The VA rewrote the genitourinary rating schedule effective November 14, 2021. Before that date, DC 7508 assigned 30% for recurrent stone formation requiring one or more of the following: diet therapy, drug therapy, or invasive or non-invasive procedures more than two times per year. Diet therapy and drug therapy were each a standalone path to 30%.
The current version deleted both. A veteran on potassium citrate and a low oxalate diet who has never needed a procedure met the old criteria and does not meet the current ones.
Two consequences worth knowing:
- If you are filing now, the diet and drug arguments no longer reach 30% under DC 7508. Only the procedure count does.
- If you already hold a 30% rating awarded under the old criteria, that rating is not automatically cut. The 2021 rule applies to claims received on or after November 14, 2021, and a rating in effect for 20 years or more is protected from reduction under 38 CFR 3.951 except for fraud. Existing evaluations are not re-adjudicated under the new schedule just because the schedule changed.
The old diet and drug language does survive in one place. DC 7511, stricture of the ureter, still reads: rate as hydronephrosis, except for recurrent stone formation requiring one or more of the following: 1. diet therapy 2. drug therapy 3. invasive or non-invasive procedures more than two times per year, at 30%. If a documented ureteral stricture is part of your picture, that is a separate diagnostic code with more generous criteria, and it is worth raising by name.
Why So Many Kidney Stone Claims Land at 0%
Say it plainly: an isolated stone episode with no recurrence and no ongoing therapy does not meet the recurrence bar, and it will be rated 0%.
The VA is not rating the pain of the stone you passed in 2011. It is rating the current, ongoing disability picture. The most common fact patterns that produce 0%:
- One or two documented stones total, both resolved, no active treatment.
- Stones documented in service, nothing since separation. Service connection may be granted, but at 0%.
- Ongoing preventive care only, meaning hydration counseling, dietary changes, and daily medication with no colic episodes and no procedures.
- Incidental stones found on a CT scan ordered for something else, with no symptoms at all.
A 0% rating is not nothing. It establishes service connection, which is the hard part of any claim. It also gives you VA health care priority consideration, and it means a later increase claim only has to prove worsening, not causation. If your stones become recurrent five years from now, an existing 0% turns a difficult claim into a straightforward one.
Higher Value Routes Worth Checking
If direct DC 7508 is going to give you 0% or 10%, these are the paths that actually change the number.
Secondary Service Connection
Stones frequently arise from something already service connected. A secondary claim requires a diagnosis, an established service-connected condition, and a medical nexus opinion tying the two. Common theories:
- Medication side effects. Long-term use of topiramate for service-connected migraines or seizures, certain diuretics, and some antiretrovirals are documented stone risk factors.
- Gout and uric acid stones. Service-connected gout is a hyperuricemia condition, and uric acid stones are a recognized complication. If you are rated for gout, get your stone composition analysis into the file.
- Chronic dehydration. Heat injury history, deployments to hot climates, and service-connected conditions that cause fluid loss.
- Immobility. Service-connected orthopedic or spinal conditions that limit mobility raise stone risk through bone resorption.
- Recurrent urinary tract infections leading to struvite stones.
The nexus opinion is the whole claim. A private nephrologist or urologist writing that it is at least as likely as not that your stones were caused or aggravated by the service-connected condition is worth more than a hundred pages of treatment notes.
Progression to Reduced Kidney Function
Repeated obstruction, repeated infection, and repeated procedures can leave permanent damage. Once kidney function drops, the rating leaves DC 7508 entirely and moves to renal dysfunction under 38 CFR 4.115a, where percentages run 0%, 30%, 60%, 80%, and 100% based on GFR. That is a different and much higher scale. If your labs show a GFR below 60 sustained across three or more months, read the full breakdown in our guide to the VA disability rating for chronic kidney disease and make sure your claim is being evaluated there.
The Predominant Dysfunction Rule
38 CFR 4.115a instructs that where diagnostic codes point to renal dysfunction, voiding dysfunction, urinary frequency, obstructed voiding, or urinary tract infection, only the predominant area of dysfunction is considered for rating purposes. Distinct disabilities may still be rated separately under 38 CFR 4.14 if the symptoms do not overlap. Practically, if your stones cause recurrent symptomatic infections requiring stent or nephrostomy drainage, the urinary tract infection criteria in 4.115a also reach 30%, and the rater should assign whichever area is predominant. Ask for consideration under every applicable area rather than assuming DC 7508 is the ceiling.
2026 Monthly Pay for a Kidney Stone Rating
VA compensation rates rose 2.8% effective December 1, 2025. Monthly amounts for a veteran with no dependents:
| Rating | Monthly payment (2026) |
|---|
| 30% | $552.47 |
| 20% | $356.66 |
| 10% | $180.42 |
| 0% | $0, service connection on record |
Amounts increase with a spouse, children, or dependent parents starting at the 30% level. At 30% with a spouse and no children, the 2026 rate is $617.47. Kidney stones alone rarely produce a standalone rating above 30%, but the percentage combines with your other service-connected conditions under the VA combined ratings table, and moving from a 70% combined rating to 80% is a meaningful jump.
Evidence That Moves a Kidney Stone Claim
Build the file around the two facts the criteria actually turn on: procedure count and colic frequency.
- Procedure records with dates. Operative reports for ureteroscopy, lithotripsy, stent placement and removal, and percutaneous nephrolithotomy. Three dated procedures inside one 12 month window is the 30% argument, so make the dates unmissable.
- Imaging. CT stone protocol, renal ultrasound, or KUB films showing stones and any hydronephrosis.
- Emergency and urgent care records documenting renal colic episodes, one by one.
- Stone composition analysis, which is the piece that supports secondary theories tied to gout, medication, or infection.
- Current labs, including creatinine, eGFR, and urinalysis, to check whether renal dysfunction criteria apply.
- A completed DBQ. VA Form 21-0960J-1, the Kidney Conditions (Nephrology) Disability Benefits Questionnaire, has a section specifically for nephrolithiasis, hydronephrosis, ureterolithiasis, and stricture of the ureter. Your own urologist can complete it and you can submit it as evidence.
- A lay statement counting your attacks over the past year, describing missed work and emergency visits.
How to File
- Confirm your diagnosis is documented. Imaging or a stone analysis in a medical record, not just a history of flank pain.
- Choose your theory. Direct service connection if the stones started in service, secondary if they flow from an already service-connected condition, or an increase claim if you are already rated and your stone activity has gotten worse.
- Gather records first. File an intent to file at va.gov to lock in your effective date, then take up to a year to assemble evidence.
- File VA Form 21-526EZ online at va.gov, by mail, or through an accredited VSO representative. Representation is free through organizations like the DAV, VFW, and American Legion.
- Attend the C&P exam. Bring your procedure dates. Describe a bad year, not a good week. If the examiner asks how often you have attacks, give a number and the dates behind it.
- Review the decision letter carefully. Check which diagnostic code was used and whether procedures were counted correctly. If the rater used DC 7509 and never addressed the DC 7508 procedure exception, that is a specific, appealable error.
If the decision is wrong, you have one year to file a Supplemental Claim with new evidence, a Higher-Level Review for a senior reviewer to look at the same record, or a Board appeal. Miscounted procedures and unaddressed secondary theories are the two most common fixable errors on these claims.
Frequently Asked Questions
What is the highest VA rating for kidney stones?
30% under DC 7508 or DC 7509. Stones by themselves do not reach higher on those codes. A rating above 30% requires the case to move to renal dysfunction under 38 CFR 4.115a, where GFR based criteria run to 100%, or to a separate service-connected condition rated on its own.
How many kidney stones do I need for a 30% VA rating?
The regulation counts procedures, not stones. You need recurrent stone formation requiring invasive or non-invasive procedures more than two times per year, so three or more procedures in a 12 month window. Alternatively, 30% is available under DC 7509 for frequent colic attacks with infection and impaired kidney function.
Does taking medication for kidney stones get me 30%?
Not under the current criteria. Drug therapy and diet therapy were removed from DC 7508 effective November 14, 2021. Both still appear in DC 7511 for stricture of the ureter, so if you have a documented ureteral stricture, that code should be considered.
Can I get VA disability for kidney stones that started after I left service?
Yes, through secondary service connection or presumptive routes. If the stones flow from a service-connected condition such as gout, medication taken for a service-connected condition, or recurrent service-connected urinary infections, they can be service connected regardless of when they first appeared. You need a medical nexus opinion.
Why did I get 0% for kidney stones when the pain is severe?
Because the criteria measure frequency and treatment intensity, not pain. Under 38 CFR 4.31, a 0% is assigned whenever the requirements for a compensable evaluation are not met, and an isolated stone with no recurrence and no procedures does not meet the 10% bar. Keep the 0%, document every future episode, and file for an increase when the record supports it.
Do kidney stones qualify under the PACT Act?
Kidney stones are not on the PACT Act presumptive list. Chronic kidney disease is also not a listed presumptive, though several toxic exposure presumptives can damage kidney function indirectly. Burn pit and Camp Lejeune exposure claims for kidney conditions are generally developed on a direct or secondary basis with a medical opinion.
Will a 30% kidney stone rating be reduced if my stones stop?
It can be. Ratings that are not permanent are subject to routine future examination, and if procedures stop and colic resolves, the VA can propose a reduction with notice and a chance to respond. A rating continuously in effect for 20 years or more is protected from reduction under 38 CFR 3.951 absent fraud.
