N07.7 — Hereditary nephropathy, not elsewhere classified with diffuse crescentic glomerulonephritis
N07.7 is a billable, specific ICD-10-CM code for hereditary nephropathy, not elsewhere classified 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.
- Hereditary nephropathy, not elsewhere classified with extracapillary glomerulonephritis
Risk adjustment
N07.7 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
N07.7 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
How N07.7 is indexed
Coders do not find codes by browsing the tabular list — they look them up in the alphabetic index, under the word the physician wrote. These are the index entries that lead here, so you can see which chart wordings map to N07.7.
