G89.0 — Central pain syndrome
G89.0 is a billable, specific ICD-10-CM code for central pain syndrome. It is valid for submission on a claim.
Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Déjérine-Roussy syndrome
- Myelopathic pain syndrome
- Thalamic pain syndrome (hyperesthetic)
Excludes1 inherited from the categories above G89.0
These are not written on G89.0, but they bind it: a note on a category applies to every code beneath it. Billing G89.0 with anything listed here is a denial.
Excludes2 inherited from the categories above G89.0
Also inherited, and the opposite of Excludes1: these conditions are not part of G89.0, but a patient can have both, so you may code both.
Written on G89 — Pain, not elsewhere classified

- vulvar vestibulitis (N94.810)
- vulvodynia (N94.81-)
Other codes that can never be billed with G89.0
These codes carry an Excludes1 note pointing at G89.0. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading G89.0 alone.
Risk adjustment
G89.0 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
G89.0 is named in 8 Medicare coverage policies — 3 listing it as supporting medical necessity, and 5 listing it as NOT covered. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.

- A59480Billing and Coding: Trigger Point Injections (TPI)not covered
- A59487Billing and Coding: Trigger Point Injections (TPI)not covered
- A59498Billing and Coding: Trigger Point Injections (TPI)not covered
How G89.0 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 G89.0.
- Central pain syndrome
- Déjérine-Roussy syndrome
- Anesthesia, anesthetic›hyperesthetic, thalamic
- Myelopathic›pain syndrome
- Syndrome›central pain
- Syndrome›Déjérine-Roussy
- Syndrome›myelopathic pain
- Syndrome›thalamic pain(hyperesthetic)
Code history
G89.0 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.

Questions about G89.0
- Is G89.0 a billable ICD-10-CM code?
- Yes. G89.0 is a billable, specific ICD-10-CM code and is valid for submission on a claim.
- Where does G89.0 sit in the tabular list?
- Diseases of the nervous system (G00-G99), in the block Other disorders of the nervous system (G89-G99).
- What cannot be coded together with G89.0?
- G89.0 carries Excludes1 notes, which means the conditions they list can never be coded together with it on the same encounter. Some are written on the categories above G89.0 (G89) and apply to it just the same.
