Inclusion Terms

Alternative terms the tabular list files under this code.

  • Neonatal stroke
  • Perinatal arterial ischemic stroke
  • Perinatal cerebral infarction

Excludes1 — Not Coded Here

Conditions generally not reported together with this code (Excludes1) -- an error unless the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).

Excludes2 — Not Included Here

Conditions not covered by this code, but which may be reported alongside it when both are present.

Coder workflow for P91.82

MedCoder structured workflow — derived from this code’s own official record

Before you code P91.82

  1. P91.82 is not reportable as written. Select the more specific code beneath it that the documentation supports. Codes are reported to the highest level of specificity the classification provides (Guidelines I.B.2).

    ReviewP91.821, P91.822, P91.823, P91.829

    See the relationships section · Guide: How to choose an ICD-10-CM code →

  2. Check the Excludes1 note: if the documentation supports a condition named there, do not simply proceed with P91.82. Excludes1 conditions are not reported together with this code unless the record shows they are unrelated (Guidelines I.A.12.a).

    See the official tabular notes

Choose the right path

  1. Does the documentation support one of the more specific codes beneath P91.82?
    Yes → Select that code and continue the checks below on its own page.
    No → P91.82 cannot be reported as written; query for the specificity its subcategory needs.

    ReviewP91.821, P91.822, P91.823, P91.829

  2. Does the documentation support a condition named in P91.82’s Excludes1 note?
    Yes → Do not simply proceed: review the excluded code. Both are reported only when the record shows the two conditions are unrelated.
    No → Continue.

Consider P91.82. Then confirm the code is valid for the date of service in the Verify section.

Documentation check

The provider’s diagnostic statement
Codes are assigned from the provider’s documented diagnosis, not from clinical criteria, test values or a medication list (Guidelines I.A.19).

Official instructions as workflow

  • Excludes1 — check before selecting P91.82(1 note)

    Coding workflow: If the documentation supports a condition named in this note, do not simply proceed with P91.82: the two are not reported together. The one exception is when the record shows the two conditions are unrelated to each other.

    CompareI63

    See the official tabular notes · Guidelines I.A.12.a

  • Excludes2 — not part of P91.82(1 note)

    Coding workflow: The conditions named in this note are not included in P91.82. When the record documents both, both may be reported; the note is a boundary, not a prohibition.

Coding decision scenarios

Pattern scenarios for this code’s structure — decision rules, not clinical cases

Documentation: Both the condition P91.82 describes and a condition named in its Excludes1 note are documented for the same encounter.

Coding question: Can both codes be reported?

Path: Review the Excludes1 note and the excluded code, and look for a provider statement on whether the two conditions are related.

Reason: Excludes1 means the two are not coded together; the exception is when the record shows the conditions are unrelated to each other (Guidelines I.A.12.a).

ReviewI63

Every row is derived from this code’s own record — its title, tabular notes, 7th-character family and same-category siblings — with fixed MedCoder wording; nothing is inferred about a patient. The official notes and guideline text are in the sections each row links to, and they control.

Relationships & Classification

MedCoder structured relationships — computed from published CMS and AHRQ datasets

Other codes that name P91.82 or its code family, from the CMS ICD-10-CM tabular instructional notes. Tabular-note edges are stored at the code family level that carries each note.

Referenced by 2 Excludes1 notes across 2 chapters: I63 — Cerebral infarction, P91.0 — Neonatal cerebral ischemia.

These codes’ tabular lists mark this diagnosis as mutually exclusive — not reported together unless the conditions are documented as unrelated.
