Is F78.A billable?

No — F78.A is a non-billable header code. F78.A 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 2 billable codes beneath F78.A.

Excludes1 — never code together — inherited from F70-F79

The conditions below can never be reported together with F78.A on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

  • borderline intellectual functioning, IQ above 70 to 84 (R41.83)

Code first — inherited from F70-F79

The underlying condition below must be sequenced before F78.A. F78.A describes a manifestation and cannot be the principal or first-listed diagnosis.

  • any associated physical or developmental disorders

Excludes2 — not included here — inherited from Chapter 5

The conditions below are not part of F78.A, but a patient may have both at the same time. When documentation supports it, F78.A and the excluded code may both be reported.

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