G98.0 — Neurogenic arthritis, not elsewhere classified
G98.0 is a billable, specific ICD-10-CM code for neurogenic arthritis, not elsewhere classified. It is valid for submission on a claim.
Excludes1 — never code together
These conditions cannot occur together. Billing both on the same encounter is a denial.
Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Nonsyphilitic neurogenic arthropathy NEC
- Nonsyphilitic neurogenic spondylopathy NEC
Other codes that can never be billed with G98.0
These codes carry an Excludes1 note pointing at G98.0. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading G98.0 alone.
- M49Spondylopathies in diseases classified elsewhere
Risk adjustment
G98.0 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
G98.0 is named in 1 Medicare coverage policy — 1 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.

How G98.0 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 G98.0.
- Arthritis, arthritic›in›neurological disorder NEC
- Arthritis, arthritic›neuropathic›nonsyphilitic NEC
- Arthropathy›neuropathic›nonsyphilitic NEC
