  • Mild neurocognitive impairment due to a known physiological condition

Excludes1 — Not Coded Here

Excludes2 — Not Included Here

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

Coder workflow for F06.7

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

Before you code F06.7

  1. F06.7 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).

    ReviewF06.70, F06.71

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

  2. F06.7’s title joins a condition with an associated condition or complication. Confirm each component is documented. Where the classification presumes the link through the “with” convention, only a provider statement that the conditions are unrelated defeats it. A combination code is assigned only when it fully identifies the documented conditions; a required second code for the stage, type or manifestation is still reported when the notes ask for it (Guidelines I.B.9, I.A.15).

    Guide: Combination codes →

  3. Check the Excludes1 note: if the documentation supports a condition named there, do not simply proceed with F06.7. 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 F06.7?
    Yes → Select that code and continue the checks below on its own page.
    No → F06.7 cannot be reported as written; query for the specificity its subcategory needs.

    ReviewF06.70, F06.71

  2. Does the documentation support a condition named in F06.7’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.

    ReviewR41.81, R41.82, G31.9, F01, F02, F03

  3. Is the underlying (etiologic) condition the Code First note names documented?
    Yes → Sequence the underlying condition first, then F06.7.
    No → Continue; do not add an underlying condition the record does not document.

    ReviewG30, B20, G10, G31.83, G31.09, G20

Consider F06.7. 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).
Severity
Mild, moderate or severe as the provider states it; severity is not inferred from the clinical picture.
The associated condition or complication
Whether the associated condition the title names is documented; the “with” convention presumes some links, and a provider statement that the conditions are unrelated defeats it (Guidelines I.A.15).
The underlying (etiologic) condition
Named in the Code First note; sequenced before this code when documented (Guidelines I.A.13).

Official instructions as workflow

  • Excludes1 — check before selecting F06.7(10 notes)

    Coding workflow: If the documentation supports a condition named in this note, do not simply proceed with F06.7: the two are not reported together. The one exception is when the record shows the two conditions are unrelated to each other.

    CompareR41.81, R41.82, G31.9, F01, F02, F03

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

  • Excludes2 — not part of F06.7(3 notes)

    Coding workflow: The conditions named in this note are not included in F06.7. When the record documents both, both may be reported; the note is a boundary, not a prohibition.

    CompareF05

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

  • Code First — sequencing check(11 notes)

    Coding workflow: Check whether the underlying or etiologic condition the note names is documented. When it is, sequence it before F06.7. Do not add an underlying condition the record does not document.

Coding decision scenarios

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

Documentation: Both the condition F06.7 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).

ReviewR41.81, R41.82, G31.9, F01, F02, F03

Documentation: Only one of the components this code’s title joins is documented.

Coding question: Is F06.7 supported?

Path: Review the code for the documented component on its own.

Reason: A combination code is assigned only when it fully identifies the documented conditions; otherwise the documented component takes its own code (Guidelines I.B.9).

Documentation: The underlying condition the Code First note names is documented alongside this condition.

Coding question: How are the two sequenced?

Path: Review the Code First note.

Reason: The underlying condition is sequenced first and the manifestation follows (Guidelines I.A.13).

Code Overview

Mild neurocognitive disorder due to known physiological condition is a non-billable ICD-10-CM category code (F06.7). A more specific billable subcode must be selected for claims submission.

Decision Points

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

  1. Sequencing: 11 Code First instructions — the underlying condition is sequenced before this code when present. See the Code First notes
  2. 10 Excludes1 entries — codes named there are generally not reported together with this code (Guidelines I.A.12.a). See the Excludes1 notes
  3. 3 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

  • Not billable as written — a more specific code is required: F06.70, F06.71.

Relationships & Classification

MedCoder structured relationships — computed from published CMS and AHRQ datasets

Other codes that name F06.7 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 5 Excludes1 notes across 2 chapters: F01.A — Vascular dementia, mild, F02 — Dementia in other diseases classified elsewhere, F03.A — Unspecified dementia, mild, F09 — Unspecified mental disorder due to known physiological condition, G31.84 — Mild cognitive impairment of uncertain or unknown etiology.

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

Referenced by 2 Excludes2 notes: F63.1 — Pyromania (via F06.-), F63.2 — Kleptomania (via F06.-).

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

Referenced by 8 Use Additional Code instructions across 3 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, G31.09 — Other frontotemporal neurocognitive disorder, G31.83 — Neurocognitive disorder with Lewy bodies, S06 — Intracranial injury.

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