G25.0

G25.0 — Essential tremor

Billable / specific codeICD-10-CM

G25.0 is a billable, specific ICD-10-CM code for essential tremor. 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.

tremor NOS (R25.1)

Inclusion terms

Alternative wordings a physician may use in the chart for this same code.

Familial tremor

Other codes that can never be billed with G25.0

These codes carry an Excludes1 note pointing at G25.0. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading G25.0 alone.

R25.1Tremor, unspecified

Risk adjustment

G25.0 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

G25.0 is named in 30 Medicare coverage policies — 30 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.

How G25.0 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 G25.0.

Tremor›essential(benign)
Tremor›familial
Tremor›hereditary
