Coder workflow for F63

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

Before you code F63

1. F63 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).

   ReviewF63.0, F63.1, F63.2, F63.3, F63.8, F63.9

   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 F63?
   Yes → Select that code and continue the checks below on its own page.
   No → F63 cannot be reported as written; query for the specificity its subcategory needs.

   ReviewF63.0, F63.1, F63.2, F63.3, F63.8, F63.9

Consider F63. 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 F63(2 notes)

  Coding workflow: The conditions named in this note are not included in F63. When the record documents both, both may be reported; the note is a boundary, not a prohibition.

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 F63 — 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.

• 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 habitual excessive use of alcohol or psychoactive substances adds F10; it is not part of this code and both may be reported when both are documented.

• F19— 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 habitual excessive use of alcohol or psychoactive substances adds F19; it is not part of this code and both may be reported when both are documented.

• F65— 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 impulse disorders involving sexual behavior adds F65; it is not part of this code and 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.
