GB42 — Persistent proteinuria or albuminuria
ICD-11 GB42 — Persistent proteinuria or albuminuria
Persistent albuminuria >3mg/mmol creatinine or >30mg/day is regarded as abnormal, indicative and often the first manifestation of chronic kidney disease (KDOQI, KDIGO). In surveillance for CKD in “at risk” patients such as diabetics, urinalysis for albuminuria is recommended by most clinical practice guidelines. This diagnosis does not refer to intermittent proteinuria as in orthostatic or exercise induced proteinuria, nor to non-albuminuric proteinuria such as Bence Jones (immunoglobulin light chain) proteinuria.
The diagnosis includes nothing.
It excludes 6 items.
- Orthostatic proteinuria (MF96.0)
- proteinuria NOS (MF96)
- Gestational proteinuria without hypertension (JA22.0)
- Bence Jones proteinuria (MF96.1)
- Nephrotic syndrome (GB41)
- albuminuria NOS (MF96)
Diagnosis with code GB42 contains 4 clarifying diagnoses:
- GB42.0 — Albuminuria, Grade A2
- GB42.1 — Albuminuria, Grade A3
- GB42.Y — Other specified persistent proteinuria or albuminuria
- GB42.Z — Persistent proteinuria or albuminuria, unspecified
