Before you code A02.2

  1. A02.2 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).

Choose the right path

  1. Does the documentation support one of the more specific codes beneath A02.2?
    Yes → Select that code and continue the checks below on its own page.
    No → A02.2 cannot be reported as written; query for the specificity its subcategory needs.

    ReviewA02.20, A02.21, A02.22, A02.23, A02.24, A02.25, A02.29

Consider A02.2. 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).

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 A02.2 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 1 Excludes1 note: A05 — Other bacterial foodborne intoxications, not elsewhere classified (via A02.-).

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

Referenced by 6 Excludes2 notes: P35 — Congenital viral diseases (via A02.-), P35-P39 — Infections specific to the perinatal period (P35-P39) (via A02.-), P36 — Bacterial sepsis of newborn (via A02.-), P37 — Other congenital infectious and parasitic diseases (via A02.-), P38 — Omphalitis of newborn (via A02.-), P39 — Other infections specific to the perinatal period (via A02.-).

These codes’ tabular lists name this diagnosis as distinct — both may be reported when both are documented.

Referenced by 1 Code First instruction: M49 — Spondylopathies in diseases classified elsewhere (via A02.-).

Each of these codes carries a Code First note naming this condition — when that code is reported, THIS code is sequenced first, ahead of it.
