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

The codes most likely to be picked instead of F02.B2 — 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.

• F06.7— Excludes1 conflict (Excludes1 — generally not reported together)

  Not coded here — the tabular list excludes this pair for the same encounter.

  Not reported together with this code, except where the two conditions are documented as unrelated.

  What moves you there: Documentation of mild neurocognitive disorder due to known physiological condition with or without behavioral disturbance moves the case to F06.7; the two are not reported together unless documented as unrelated.

  Full comparison: F02.B2 vs F06.7 →

• F10— 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 dementia in alcohol and psychoactive substance disorders adds F10; it is not part of this code and both may be reported when both are documented.

  Full comparison: F02.B2 vs F10 →

• F19— Excludes2 relationship (Informational)

  Distinct conditions — both may be reported.

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

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.

Indexed Clinical Terms (1)

Official source data — entries quoted as published, in the Index’s own lookup phrasing

Clinical term phrases from the official ICD-10-CM Index to Diseases and Injuries that map to this code. These are alphabetic-index entries shown as the Index writes them — lookup phrasing, not necessarily the wording of a final diagnosis.

• Dementia (degenerative (primary)) (persisting) (unspecified severity) (without behavioral disturbance, psychotic disturbance, mood disturbance, and anxiety), in (due to), diseases specified elsewhere (unspecified severity) (without behavioral disturbance, psychotic disturbance, mood disturbance, and anxiety), moderate, with, psychotic disturbance (delusional state) (hallucinations) (paranoia) (suspiciousness)

Decision Points

The directives on this code's own record, as a pre-claim checklist.

1. Sequencing: 25 Code First instructions — the underlying condition is sequenced before this code when present. See the Code First notes
2. 1 Excludes1 entry — codes named there are generally not reported together with this code (Guidelines I.A.12.a). See the Excludes1 notes
3. 2 Excludes2 entries — those conditions are not part of this code and may be reported additionally when documented. See the Excludes2 notes

Checklist rows are derived from this code's own official directives; the wording of each check is MedCoder editorial. The official notes themselves are in the sections each row links to.

Verify Before Coding

• Principal-diagnosis restriction. This is a manifestation code: the Medicare Code Editor requires the underlying condition (etiology) to be sequenced first, with this code reported after it.
• CC as a secondary diagnosis (FY2027). Can raise the stay's MS-DRG severity tier.

From the code registry, the Medicare Code Editor, and the MS-DRG Definitions Manual. Check it against a full claim in Claim Check.

Relationships & Classification

MedCoder structured relationships — computed from published CMS and AHRQ datasets

Other codes that name F02.B2 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: F06.7 — Mild neurocognitive disorder due to known physiological condition (via F02.-), G31.84 — Mild cognitive impairment of uncertain or unknown etiology (via F02.-).

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

Referenced by 3 Excludes2 notes: F06 — Other mental disorders due to known physiological condition (via F02.-), F63.1 — Pyromania (via F02.-), F63.2 — Kleptomania (via F02.-).

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

Referenced by 5 Use Additional Code instructions across 2 chapters: A81 — Atypical virus infections of central nervous system, G10 — Huntington's disease, G20 — Parkinson's disease, G30 — Alzheimer's disease, G31 — Other degenerative diseases of nervous system, not elsewhere classified.

These codes instruct coders to additionally report this code when it applies.

MS-DRG Grouper Relationships (FY2027)

Potential MS-DRG participation — not a DRG assignment.

FY2027 MS-DRG: CC — Complication or Comorbidity. Reported as a secondary diagnosis, this code raises the stay's MS-DRG severity tier — except when the principal diagnosis is one of 20 clinically related codes on its CMS exclusion list.

Named in the grouper logic of 1 MS-DRG: DRG 884 (MDC 19).

From the CMS MS-DRG Definitions Manual (Appendices B and C). Actual DRG assignment depends on the complete claim.
