Is F02.C1 billable?

Excludes1 — never code together — inherited from F02

The conditions below can never be reported together with F02.C1 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

  • mild neurocognitive disorder due to known physiological condition with or without behavioral disturbance (F06.7-)

Code first — inherited from F02

The underlying condition below must be sequenced before F02.C1. F02.C1 describes a manifestation and cannot be the principal or first-listed diagnosis.

  • Alzheimer's (G30.-)
  • cerebral lipidosis (E75.4)
  • Creutzfeldt-Jakob disease (A81.0-)

Excludes2 — not included here — inherited from Chapter 5

The conditions below are not part of F02.C1, but a patient may have both at the same time. When documentation supports it, F02.C1 and the excluded code may both be reported.

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

Excludes2 — not included here — inherited from F02

The conditions below are not part of F02.C1, but a patient may have both at the same time. When documentation supports it, F02.C1 and the excluded code may both be reported.

  • dementia in alcohol and psychoactive substance disorders (F10-F19, with .17, .27, .97)
  • vascular dementia (F01.5-, F01.A-, F01.B-, F01.C-)
