Coder workflow for M70.2

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

Before you code M70.2

  1. M70.2 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).

    ReviewM70.20, M70.21, M70.22

    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 M70.2. 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 M70.2?
    Yes → Select that code and continue the checks below on its own page.
    No → M70.2 cannot be reported as written; query for the specificity its subcategory needs.

    ReviewM70.20, M70.21, M70.22

  2. Does the documentation support a condition named in M70.2’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.

    ReviewM71.9

Consider M70.2. Then work the Use Additional Code note, and 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).
The conditions the Use Additional Code note names
Reported with this code when documented; a conditional instruction (“if applicable”, “if known”) applies only when the record supports it.

Official instructions as workflow

  • Excludes1 — check before selecting M70.2(1 note)

    Coding workflow: If the documentation supports a condition named in this note, do not simply proceed with M70.2: the two are not reported together. The one exception is when the record shows the two conditions are unrelated to each other.

    CompareM71.9

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

  • Excludes2 — not part of M70.2(3 notes)

    Coding workflow: The conditions named in this note are not included in M70.2. When the record documents both, both may be reported; the note is a boundary, not a prohibition.

    CompareM75.5, L89

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

  • Use Additional Code — after identifying M70.2(1 note)

    Coding workflow: Check whether the documentation supports the additional code(s) the note names, and report them with M70.2 when it does. Where the instruction is conditional (“if applicable”, “if known”), it applies only when the record documents the condition.

Coding decision scenarios

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

Documentation: Both the condition M70.2 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).

ReviewM71.9

Documentation: A condition the Use Additional Code note names is documented.

Coding question: Is a second code reported with M70.2?

Path: Review the Use Additional Code note and the code it names.

Reason: The additional code is reported when the record documents the condition; a conditional instruction applies only when its condition is met (Guidelines I.A.13).

Decision Points

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

  1. 1 Use Additional Code instruction — report the named additional code(s) when the documentation supports them. See the Use Additional Code 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. 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.

Relationships & Classification

MedCoder structured relationships — computed from published CMS and AHRQ datasets

Other codes that name M70.2 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: M65 — Synovitis and tenosynovitis (via M70.-), M71 — Other bursopathies (via M70.-).

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: M76 — Enthesopathies, lower limb, excluding foot (via M70.-), M77 — Other enthesopathies (via M70.-).

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