Is P78.89 billable?

Yes, but P78.89 is an unspecified code. P78.89 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, P78.89 is an unspecified or catch-all code. Payers apply additional scrutiny to unspecified codes and many deny them when the medical record supports a more specific option, so check the documentation before selecting P78.89 — the more specific alternatives are listed below.

How is P78.89 listed in the Alphabetic Index?

These are the routes through the Alphabetic Index that lead to P78.89. They show the wording a clinician may have documented, which often differs from the Tabular description.

  • Disorderdigestivenewbornspecified NEC (of)

Excludes1 — never code together — inherited from P78

The conditions below can never be reported together with P78.89 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

  • cystic fibrosis (E84.0-E84.9)
  • neonatal gastrointestinal hemorrhages (P54.0-P54.3)

Excludes2 — not included here — inherited from Chapter 16

The conditions below are not part of P78.89, but a patient may have both at the same time. When documentation supports it, P78.89 and the excluded code may both be reported.

  • congenital malformations, deformations and chromosomal abnormalities (Q00-Q99)
  • endocrine, nutritional and metabolic diseases (E00-E88)
  • injury, poisoning and certain other consequences of external causes (S00-T88)
  • neoplasms (C00-D49)
  • tetanus neonatorum (A33)

How long has P78.89 existed?

Derived from the official order files for FY2016–FY2026. FY2017 and FY2020 publish no order file, so those years are not covered.
