Excludes2 — Not Included Here

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

Coder workflow for M26.62

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

Before you code M26.62

  1. M26.62 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).

    ReviewM26.621, M26.622, M26.623, M26.629

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

  2. Check the Excludes1 note: if the documentation supports a condition named there, do not simply proceed with M26.62. 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 M26.62?
    Yes → Select that code and continue the checks below on its own page.
    No → M26.62 cannot be reported as written; query for the specificity its subcategory needs.

    ReviewM26.621, M26.622, M26.623, M26.629

  2. Does the documentation support a condition named in M26.62’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.

    ReviewQ67.4, M27.8

Consider M26.62. 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

  • Excludes1 — check before selecting M26.62(2 notes)

    Coding workflow: If the documentation supports a condition named in this note, do not simply proceed with M26.62: the two are not reported together. The one exception is when the record shows the two conditions are unrelated to each other.

    CompareQ67.4, M27.8

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

  • Excludes2 — not part of M26.62(2 notes)

    Coding workflow: The conditions named in this note are not included in M26.62. When the record documents both, both may be reported; the note is a boundary, not a prohibition.

    CompareS03.0, S03.4

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

Coding decision scenarios

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

Documentation: Both the condition M26.62 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).

ReviewQ67.4, M27.8

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 M26.62 — 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.

  • Q67.4— 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 hemifacial atrophy or hypertrophy moves the case to Q67.4; the two are not reported together unless documented as unrelated.

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.
