Excludes1 — Not Coded Here

Coder workflow for O88.2
MedCoder structured workflow — derived from this code’s own official record
Before you code O88.2
- O88.2 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).
See the relationships section · Guide: How to choose an ICD-10-CM code →
- Confirm the condition is documented as complicating the pregnancy, childbirth, or the puerperium, and check the trimester where the code carries one and the fetus character where the category requires it. Chapter 15 codes belong on the maternal record only and take sequencing priority over codes from other chapters. It is the provider’s responsibility to state that a condition is not affecting the pregnancy; the trimester is assigned from the documentation (Guidelines I.C.15.a, I.C.15.a.1, I.C.15.a.3).
- Check the Excludes1 note: if the documentation supports a condition named there, do not simply proceed with O88.2. Excludes1 conditions are not reported together with this code unless the record shows they are unrelated (Guidelines I.A.12.a).
Choose the right path
- Does the documentation support one of the more specific codes beneath O88.2?
Yes → Select that code and continue the checks below on its own page.
No → O88.2 cannot be reported as written; query for the specificity its subcategory needs. - Does the documentation support a condition named in O88.2’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.
Consider O88.2. 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).
- Trimester
- Assigned from the documented trimester at the encounter, or the trimester in which the condition developed for inpatient stays (Guidelines I.C.15.a.3).
Official instructions as workflow
Excludes1 — check before selecting O88.2(5 notes)
Coding workflow: If the documentation supports a condition named in this note, do not simply proceed with O88.2: the two are not reported together. The one exception is when the record shows the two conditions are unrelated to each other.
CompareO03.2, O08.2, O07.2, O04.7, O03.7
See the official tabular notes · Guidelines I.A.12.a
Excludes2 — not part of O88.2(3 notes)
Coding workflow: The conditions named in this note are not included in O88.2. When the record documents both, both may be reported; the note is a boundary, not a prohibition.
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 O88.2 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).
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.

Relationships & Classification
MedCoder structured relationships — computed from published CMS and AHRQ datasets
Other codes that name O88.2 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 1 Excludes1 note: T81.7 — Vascular complications following a procedure, not elsewhere classified (via O88.-).
These codes’ tabular lists mark this diagnosis as mutually exclusive — not reported together unless the conditions are documented as unrelated.
Referenced by 4 Excludes2 notes across 2 chapters: I26 — Pulmonary embolism (via O88.-), O22 — Venous complications and hemorrhoids in pregnancy (via O88.-), O87 — Venous complications and hemorrhoids in the puerperium (via O88.-), O99.4 — Diseases of the circulatory system complicating pregnancy, childbirth and the puerperium (via O88.-).
These codes’ tabular lists name this diagnosis as distinct — both may be reported when both are documented.
Referenced by 1 Code First instruction: I74 — Arterial embolism and thrombosis (via O88.-).
Each of these codes carries a Code First note naming this condition — when that code is reported, THIS code is sequenced first, ahead of it.
