G98.0 — Neurogenic arthritis, not elsewhere classified
Is G98.0 billable?
Yes, but G98.0 is an unspecified code. G98.0 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, G98.0 is an unspecified or catch-all code. Payers apply additional scrutiny to unspecified codes and many deny them when the medical record supports a more specific option, so check the documentation before selecting G98.0 — the more specific alternatives are listed below.

How is G98.0 listed in the Alphabetic Index?
These are the routes through the Alphabetic Index that lead to G98.0. They show the wording a clinician may have documented, which often differs from the Tabular description.
- Arthritis, arthritic › in › neurological disorder NEC (acute) (chronic) (nonpyogenic) (subacute)
- Arthritis, arthritic › neuropathic › nonsyphilitic NEC (acute) (chronic) (nonpyogenic) (subacute)
- Arthropathy › neuropathic › nonsyphilitic NEC
Excludes1 — never code together
The conditions below can never be reported together with G98.0 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
Inclusion terms
Alternative wording in documentation that is classified to G98.0.
- Nonsyphilitic neurogenic arthropathy NEC
- Nonsyphilitic neurogenic spondylopathy NEC
Excludes2 — not included here — inherited from Chapter 6
The conditions below are not part of G98.0, but a patient may have both at the same time. When documentation supports it, G98.0 and the excluded code may both be reported.
- certain conditions originating in the perinatal period (P04-P96)
- certain infectious and parasitic diseases (A00-B99)
- complications of pregnancy, childbirth and the puerperium (O00-O9A)
- congenital malformations, deformations, and chromosomal abnormalities (Q00-Q99)
- endocrine, nutritional and metabolic diseases (E00-E88)
- injury, poisoning and certain other consequences of external causes (S00-T88)
- neoplasms (C00-D49)
- symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified (R00-R94)
How long has G98.0 existed?
G98.0 has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.
Derived from the official order files for FY2016–FY2026. FY2017 and FY2020 publish no order file, so those years are not covered.
Which codes are confused with G98.0?
ICD-10-CM declares these codes mutually exclusive with G98.0 — exactly one of each pair can be correct for a given encounter.
