Questions About F07.0Overview

What is the ICD-10 code for personality change due to known physiological condition?

The ICD-10-CM code for personality change due to known physiological condition is F07.0 (sometimes written as F070). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

Is F07.0 a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report personality change due to known physiological condition on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

What MS-DRG does F07.0 group to?

On inpatient claims, personality change due to known physiological condition maps to MS-DRG 884 (organic Disturbances and Intellectual Disability), which carries a relative weight of 1.5998. Higher weights mean higher Medicare reimbursement.

Can F07.0 be a principal diagnosis?

No. The Medicare Code Editor rejects this code as a principal diagnosis because personality change due to known physiological condition describes a circumstance that influences health status rather than a current illness. Report it as a secondary diagnosis.

Can F07.0 be reported with G31.84?

Not as a rule. The Excludes1 note on F07.0 lists "mild cognitive impairment (G31.84)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
