Coder workflow for I87.2

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

Before you code I87.2

1. Check the Excludes1 note: if the documentation supports a condition named there, do not simply proceed with I87.2. 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 a condition named in I87.2’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.

   ReviewI83.1, I83.2

Consider I87.2. Then work the Use Additional Code note and review the Code Also 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).

Acuity

Acute or chronic as documented; when both are documented and separate codes exist, both are reported with the acute code first (Guidelines I.B.8).

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 I87.2(1 note)

  Coding workflow: If the documentation supports a condition named in this note, do not simply proceed with I87.2: the two are not reported together. The one exception is when the record shows the two conditions are unrelated to each other.

  CompareI83.1, I83.2

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

• Use Additional Code — after identifying I87.2(1 note)

  Coding workflow: Check whether the documentation supports the additional code(s) the note names, and report them with I87.2 when it does. Where the instruction is conditional (“if applicable”, “if known”), it applies only when the record documents the condition.

  ReviewL97

  See the official tabular notes · Guidelines I.A.13

• Code Also — related condition(5 notes)

  Coding workflow: Review the related condition when both are documented and the instruction applies. A Code Also note does not fix sequencing; the order follows the circumstances of the encounter.

Coding decision scenarios

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

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.

Indexed Clinical Terms (6)

Official source data — entries quoted as published, in the Index’s own lookup phrasing

Clinical term phrases from the official ICD-10-CM Index to Diseases and Injuries that map to this code. These are alphabetic-index entries shown as the Index writes them — lookup phrasing, not necessarily the wording of a final diagnosis.

• Dermatitis (eczematous), stasis
• Eczema (acute) (chronic) (erythematous) (fissum) (rubrum) (squamous), stasis
• Insufficiency, insufficient, venous (chronic) (peripheral)
• Stasis, dermatitis
• Stasis, ulcer, without varicose veins
• Ulcer, ulcerated, ulcerating, ulceration, ulcerative, stasis (venous), without varicose veins

Don’t confuse I87.2 with…

MedCoder analysis — pairs from this code’s official notes, distinctions written by MedCoder

The codes most likely to be picked instead of I87.2 — 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.

• I83.1— 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 stasis dermatitis with varicose veins of lower extremities moves the case to I83.1; the two are not reported together unless documented as unrelated.

  Full comparison: I87.2 vs I83.1 →

• I83.2— 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 stasis dermatitis with varicose veins of lower extremities moves the case to I83.2; the two are not reported together unless documented as unrelated.

  Full comparison: I87.2 vs I83.2 →

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.

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. 5 Code Also notes — a second code may apply; the guidelines leave its sequencing to the circumstances of the encounter. See the Code Also notes
3. 1 Excludes1 entry — codes named there are generally not reported together with this code (Guidelines I.A.12.a). See the Excludes1 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 I87.2 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 12 Excludes2 notes: L20 — Atopic dermatitis, L20-L30 — Dermatitis and eczema (L20-L30), L21 — Seborrheic dermatitis, L22 — Diaper dermatitis, L23 — Allergic contact dermatitis, L24 — Irritant contact dermatitis, L25 — Unspecified contact dermatitis, L26 — Exfoliative dermatitis, L27 — Dermatitis due to substances taken internally, L28 — Lichen simplex chronicus and prurigo, L29 — Pruritus, L30 — Other and unspecified dermatitis.

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

MS-DRG Grouper Relationships (FY2026)

Potential MS-DRG participation — not a DRG assignment.

FY2026 MS-DRG: not on the CMS CC/MCC list — as a secondary diagnosis this code does not change MS-DRG severity for that release.

Named in the grouper logic of 3 MS-DRGs: DRG 299 (MDC 05), DRG 300 (MDC 05), DRG 301 (MDC 05).

From the CMS MS-DRG Definitions Manual (Appendices B and C). Actual DRG assignment depends on the complete claim.
