Coder workflow for H35.34

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

Before you code H35.34

  1. H35.34 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).

    ReviewH35.341, H35.342, H35.343, H35.349

    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 H35.34?
    Yes → Select that code and continue the checks below on its own page.
    No → H35.34 cannot be reported as written; query for the specificity its subcategory needs.

    ReviewH35.341, H35.342, H35.343, H35.349

Consider H35.34. 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 H35.34(1 note)

    Coding workflow: The conditions named in this note are not included in H35.34. 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.
