Interstitial nephritis, including gouty nephropathy, disorders of calcium metabolism
Diagnostic code 7537 · Genitourinary system · 38 CFR 4.115b
Rating criteria: the exact regulation text
Quoted from 38 CFR 4.115b. The "Rating" column is the percentage VA assigns for that level.
Printed at the start of this table in the regulation:
| Criteria | Rating |
|---|---|
| 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. |
| Criteria | Rating |
|---|---|
| 7537 Interstitial nephritis, including gouty nephropathy, disorders of calcium metabolism: | |
| Rate as renal dysfunction. |
§ 4.115a Ratings of the genitourinary system—dysfunctions.
This code's own text says to use this formula.
| Criteria | Rating |
|---|---|
| Renal dysfunction: | |
| Chronic kidney disease with glomerular filtration rate (GFR) less than 15 mL/min/1.73 m2 for at least 3 consecutive months during the past 12 months; or requiring regular routine dialysis; or eligible kidney transplant recipient | 100 |
| Chronic kidney disease with GFR from 15 to 29 mL/min/1.73 m2 for at least 3 consecutive months during the past 12 months | 80 |
| Chronic kidney disease with GFR from 30 to 44 mL/min/1.73 m2 for at least 3 consecutive months during the past 12 months | 60 |
| Chronic kidney disease with GFR from 45 to 59 mL/min/1.73 m2 for at least 3 consecutive months during the past 12 months | 30 |
| GFR from 60 to 89 mL/min/1.73 m2 and either recurrent red blood cell (RBC) casts, white blood cell (WBC) casts, or granular casts for at least 3 consecutive months during the past 12 months; or | |
| GFR from 60 to 89 mL/min/1.73 m2 and structural kidney abnormalities (cystic, obstructive, or glomerular) for at least 3 consecutive months during the past 12 months; or | |
| GFR from 60 to 89 mL/min/1.73 m2 and albumin/creatinine ratio (ACR) ≥30 mg/g for at least 3 consecutive months during the past 12 months | 0 |
| Note: GFR, estimated GFR (eGFR), and creatinine-based approximations of GFR will be accepted for evaluation purposes under this section when determined to be appropriate and calculated by a medical professional. | |
| Voiding dysfunction: | |
| Rate particular condition as urine leakage, frequency, or obstructed voiding | |
| Continual Urine Leakage, Post Surgical Urinary Diversion, Urinary Incontinence, or Stress Incontinence: | |
| Requiring the use of an appliance or the wearing of absorbent materials which must be changed more than 4 times per day | 60 |
| Requiring the wearing of absorbent materials which must be changed 2 to 4 times per day | 40 |
| Requiring the wearing of absorbent materials which must be changed less than 2 times per day | 20 |
| Urinary frequency: | |
| Daytime voiding interval less than one hour, or; awakening to void five or more times per night | 40 |
| Daytime voiding interval between one and two hours, or; awakening to void three to four times per night | 20 |
| Daytime voiding interval between two and three hours, or; awakening to void two times per night | 10 |
| Obstructed voiding: | |
| Urinary retention requiring intermittent or continuous catheterization | 30 |
| Marked obstructive symptomatology (hesitancy, slow or weak stream, decreased force of stream) with any one or combination of the following: | |
| 1. Post void residuals greater than 150 cc. | |
| 2. Uroflowmetry; markedly diminished peak flow rate (less than 10 cc/sec). | |
| 3. Recurrent urinary tract infections secondary to obstruction. | |
| 4. Stricture disease requiring periodic dilatation every 2 to 3 months | 10 |
| Obstructive symptomatology with or without stricture disease requiring dilatation 1 to 2 times per year | 0 |
| Urinary tract infection: | |
| Poor renal function: Rate as renal dysfunction. | |
| Recurrent symptomatic infection requiring drainage by stent or nephrostomy tube; or requiring greater than 2 hospitalizations per year; or requiring continuous intensive management | 30 |
| Recurrent symptomatic infection requiring 1-2 hospitalizations per year or suppressive drug therapy lasting six months or longer | 10 |
| Recurrent symptomatic infection not requiring hospitalization, but requiring suppressive drug therapy for less than 6 months | 0 |
