P91.60 — Hypoxic ischemic encephalopathy [HIE], unspecified
Is P91.60 billable?
Yes, but P91.60 is an unspecified code. P91.60 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, P91.60 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 P91.60 — the more specific alternatives are listed below.

Excludes1 — never code together — inherited from P91.6
The conditions below can never be reported together with P91.60 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
Excludes2 — not included here — inherited from Chapter 16
The conditions below are not part of P91.60, but a patient may have both at the same time. When documentation supports it, P91.60 and the excluded code may both be reported.
How long has P91.60 existed?
P91.60 has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.
Derived from the official order files for FY2016–FY2026. FY2017 and FY2020 publish no order file, so those years are not covered.
