Rated under § 4.115b. Body system: Genitourinary System.

## Rating criteria

| Rating | Criteria |

## Notes

- Note: When evaluating any claim involving loss or loss of use of one or more creative organs, refer to § 3.350 of this chapter to determine whether the veteran may be entitled to special monthly compensation. Footnotes in the schedule indicate conditions which potentially establish entitlement to special monthly compensation; however, there are other conditions in this section which under certain circumstances also establish entitlement to special monthly compensation.

# Kidney and Urinary Stones (Nephrolithiasis / Ureterolithiasis / Nephrocalcinosis)

**VA Diagnostic Code 7508 · Genitourinary System · 38 CFR § 4.115b**

## What This Condition Is

This rating entry covers kidney and urinary tract stone conditions, including:

- **Nephrolithiasis** — stones that form in the kidneys
- **Ureterolithiasis** — stones in the ureters (the tubes connecting the kidneys to the bladder)
- **Nephrocalcinosis** — calcium deposits in the kidney tissue

These are conditions of the genitourinary system, which the VA evaluates under § 4.115b of the rating schedule.

## How the VA Rates It

For Diagnostic Code 7508, the VA generally rates these stone conditions **as hydronephrosis**, meaning the criteria used for hydronephrosis are applied to determine the appropriate evaluation.

There is one specific rating level identified for this code:

| Rating | What It Reflects |
|--------|------------------|
| **30%** | Recurrent stone formation requiring invasive or non-invasive procedures more than two times per year |

In other words, a 30% evaluation is available where stones keep forming and require invasive or non-invasive procedures **more than two times per year**. Outside of that circumstance, the condition is rated as hydronephrosis.

## What the VA Looks For

When evaluating a claim under this code, the VA considers:

- Whether the condition involves **recurrent stone formation**
- Whether those recurring stones **require invasive or non-invasive procedures**
- **How often** such procedures are needed — specifically, whether they occur **more than two times per year**
- Otherwise, application of the **hydronephrosis** rating criteria

## Additional Note

When evaluating any claim involving loss or loss of use of one or more creative organs, the VA refers to § 3.350 of this chapter to determine whether the veteran may be entitled to special monthly compensation. Footnotes in the schedule indicate conditions that potentially establish entitlement to special monthly compensation; however, there are other conditions in this section which, under certain circumstances, also establish entitlement to special monthly compensation.
