Notes without a marker are published on M62.13 itself; “inherited from” names the category or block whose note applies here.

Excludes1 — Not Coded Here

Conditions generally not reported together with this code (Excludes1) -- an error unless the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).

Excludes2 — Not Included Here

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

Coder workflow for M62.13

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

Before you code M62.13

  1. M62.13 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).

    ReviewM62.131, M62.132, M62.139

    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 the code beneath M62.13. 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 M62.13?
    Yes → Select that code and continue the checks below on its own page.
    No → M62.13 cannot be reported as written. Where the codes beneath it include an unspecified code, that code applies when the record goes no further; otherwise query for the missing detail.

    ReviewM62.131, M62.132, M62.139

  2. Does the documentation support a condition named in M62.13’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.

    ReviewG72.1, R25.2, G72.0, M79.1, G25.82, M33

Report the code beneath M62.13 that the documentation supports, not M62.13 itself. Then confirm that code is valid for the date of service on its own page.

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).
Anatomical site
At the most specific level the record states; a site the classification separates cannot be assumed from a procedure or a measurement.
Any detail beyond this code’s title
What the record states that a more specific code would capture — or its absence, which itself supports the unspecified code.

Official instructions as workflow

  • Excludes1 — check before selecting M62.13(13 notes)

    Coding workflow: If the documentation supports a condition named in this note, do not simply proceed with M62.13: the two are not reported together. The one exception is when the record shows the two conditions are unrelated to each other.

    CompareG72.1, R25.2, G72.0, M79.1, G25.82, M33

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

  • Excludes2 — not part of M62.13(3 notes)

    Coding workflow: The conditions named in this note are not included in M62.13. When the record documents both, both may be reported; the note is a boundary, not a prohibition.

Coding decision scenarios

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

Documentation: Both the condition M62.13 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).

ReviewG72.1, R25.2, G72.0, M79.1, G25.82, M33

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.
