Where does R56.0 sit in the tabular list?

Symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified (R00-R99), in the block General symptoms and signs (R50-R69).

What cannot be coded together with R56.0?

R56.0 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 R56.0 (R56) and apply to it just the same.

R56.0 — Febrile convulsions

Non-billable headerICD-10-CM

R56.0 is a non-billable header ICD-10-CM code for febrile convulsions. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1 inherited from the categories above R56.0

These are not written on R56.0, but they bind it: a note on a category applies to every code beneath it. Billing R56.0 with anything listed here is a denial.

Written on R56 — Convulsions, not elsewhere classified

dissociative convulsions and seizures (F44.5)
epileptic convulsions and seizures (G40.-)
newborn convulsions and seizures (P90)

Other codes that can never be billed with R56.0

These codes carry an Excludes1 note pointing at R56.0. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading R56.0 alone.

Risk adjustment

R56.0 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.

Code history

R56.0 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.
