P29.3 ICD-10-CM Code: Persistent fetal circulation

Coding instructions

Official Tabular Instructional Notes: the inclusion, exclusion and sequencing notes published for P29.3 in the official ICD-10-CM tabular list, quoted as published.

Notes without a marker are published on P29.3 itself; “inherited from” names the category or block whose note applies here.

Coder workflow for P29.3

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

Before you code P29.3

1. P29.3 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).

   ReviewP29.30, P29.38

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

Choose the right path

1. Does the documentation support one of the more specific codes beneath P29.3?
   Yes → Select that code and continue the checks below on its own page.
   No → P29.3 cannot be reported as written; query for the specificity its subcategory needs.

   ReviewP29.30, P29.38

Consider P29.3. 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

• Excludes2 — not part of P29.3(1 note)

  Coding workflow: The conditions named in this note are not included in P29.3. When the record documents both, both may be reported; the note is a boundary, not a prohibition.

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

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.

MedCoder analysis — pairs from this code’s official notes, distinctions written by MedCoder

The codes most likely to be picked instead of P29.3 — named in its own official notes, or sharing its laterality or encounter family — with what separates them and which documentation moves the case. Each links to the full comparison.

• P29.9— Specificity relationship (Review)

  Overlapping diagnoses in the same category.

  Overlapping codes in the same category — the documentation decides which is the more specific fit.

  What moves you there: A record that documents no more than “Cardiovascular disorder originating in the perinatal period, unspecified” takes P29.9; specificity in the record moves it back here.

  Full comparison: P29.3 vs P29.9 →

• Q20— Excludes2 relationship (Informational)

  Distinct conditions — both may be reported.

  A distinct condition — both may be reported when both are documented.

  What moves you there: Documentation of congenital malformations of the circulatory system adds Q20; it is not part of this code and both may be reported when both are documented.

• Q28— Excludes2 relationship (Informational)

  Distinct conditions — both may be reported.

  A distinct condition — both may be reported when both are documented.

  What moves you there: Documentation of congenital malformations of the circulatory system adds Q28; it is not part of this code and both may be reported when both are documented.

  Full comparison: P29.3 vs Q28 →

Relationships are read from this code's own official notes, its laterality siblings and its encounter family; the wording of each distinction is MedCoder editorial, and the documentation named in each “what moves you there” line is the official note phrase or sibling title itself.
