N04.7 — Nephrotic syndrome with diffuse crescentic glomerulonephritis
N04.7 is a billable, specific ICD-10-CM code for nephrotic syndrome with diffuse crescentic glomerulonephritis. It is valid for submission on a claim.
Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Nephrotic syndrome with extracapillary glomerulonephritis
Risk adjustment
N04.7 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.
Medicare coverage
N04.7 is named in 3 Medicare coverage policies — 3 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
- A55336Billing and Coding: Retroperitoneal Ultrasound
- A56380Billing and Coding: Rituximab
- A57189Billing and Coding: Serum Magnesium
