F20 — Schizophrenia

Not billable

Is F20 billable?

No — F20 is a non-billable header code. F20 groups more specific codes and cannot be submitted on a claim. A valid ICD-10-CM code must be reported at the highest level of specificity available in its branch. Select one of the 8 billable codes beneath F20.

Excludes1 — never code together

The conditions below can never be reported together with F20 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

Use additional code

Report an additional code alongside F20 to fully describe the condition. F20 is sequenced first.

  • code, if applicable, to identify:
  • other specified cognitive deficit (R41.84-)

Excludes2 — not included here

The conditions below are not part of F20, but a patient may have both at the same time. When documentation supports it, F20 and the excluded code may both be reported.

Excludes2 — not included here — inherited from Chapter 5

The conditions below are not part of F20, but a patient may have both at the same time. When documentation supports it, F20 and the excluded code may both be reported.

  • symptoms, signs and abnormal clinical laboratory findings, not elsewhere classified (R00-R99)

How long has F20 existed?

F20 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 F20?

ICD-10-CM declares these codes mutually exclusive with F20 — exactly one of each pair can be correct for a given encounter.
