F31.60 diagnosis code: Bipolar disorder, current episode mixed, unspecified

The F31.60 is an ICD code included in the International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) used to designate “Bipolar disorder, current episode mixed, unspecified.”

The ICD-10-CM code F31.60 is used to diagnose bipolar disorder where the current episode presents as a mixed episode, featuring symptoms of both a manic episode and a major depressive disorder, but without a specified severity. This classification applies when documentation does not clarify whether the symptoms are mild, moderate, or severe.

Bipolar disorder, sometimes historically called manic depressive illness, includes a wide range of mood fluctuations, from mild major depressive disorder symptoms to full-blown current episode manic severe phases. This code may also be relevant for patients with a history of a single manic episode or other bipolar type disorder, including those transitioning from bipolar II disorder to more complex presentations.

Is the F31.60 billable?

Yes, F31.60 is a billable ICD-10-CM code appropriate for reimbursement purposes. It is used when a patient presents with a mixed episode of bipolar disorder without a specified severity level.

Clinical information

  • Bipolar disorder, current episode mixed, occurs when a patient simultaneously exhibits signs of a manic episode (such as increased energy, grandiosity, or reduced need for sleep) and a major depressive disorder (such as persistent sadness, low energy, or feelings of worthlessness).
  • The current episode manic symptoms are present but not sufficiently detailed to determine whether they meet criteria for the current episode manic severe.
  • Manic depressive illness is a historical term still sometimes used to describe bipolar disorder, reflecting the presence of alternating manic and depressive phases.
  • This diagnosis may apply to individuals initially classified under bipolar II disorder, especially if symptom complexity increases beyond the typical patterns of hypomanic episodes and major depressive episodes.
  • Accurate classification is essential for building a proper treatment plan, which typically involves mood stabilizers, psychotherapy, and careful monitoring for progression toward full remission or partial remission.
