O36.0129 ICD-10-CM Code: Maternal care for anti-D [Rh] antibodies, second trimester, other fetus

Coding instructions

Official Tabular Instructional Notes: the inclusion, exclusion and sequencing notes published for O36.0129 in the official ICD-10-CM tabular list, quoted as published.

Notes without a marker are published on O36.0129 itself; “inherited from” names the category or block whose note applies here.

7th Character Guide

"One of the following 7th characters is to be assigned to each code under category O36. 7th character 0 is for single gestations and multiple gestations where the fetus is unspecified. 7th characters 1 through 9 are for cases of multiple gestations to identify the fetus for which the code applies. The appropriate code from category O30, Multiple gestation, must also be assigned when assigning a code from category O36 that has a 7th character of 1 through 9."

• 0 — not applicable or unspecified
• 1 — fetus 1
• 2 — fetus 2
• 3 — fetus 3
• 4 — fetus 4
• 5 — fetus 5
• 9 — other fetus (this page’s code)

Coder workflow for O36.0129

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

Before you code O36.0129

1. A 7th character is required in this family. Confirm the documentation supports the character assigned — its meaning in this family is defined in the official instruction. This page’s code carries “9”. The official 7th-character definitions for this family are quoted in the guide.

   See the 7th Character Guide

2. 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).

   Guide: How to choose an ICD-10-CM code →

3. Check the Excludes1 note: if the documentation supports a condition named there, do not simply proceed with O36.0129. 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 O36.0129’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.

   ReviewZ03.7, O43.0

2. Does the documentation support one of this family’s 7th-character values?
   Yes → Assign the matching 7th character; the variant codes are in the 7th Character Guide.
   No → The code is invalid without its 7th character — query for the missing element.

Consider O36.0129. 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).

7th-character basis

The documented element this family’s 7th character records (see the official definitions in the 7th Character Guide).

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).

Fetus affected

For multiple gestations, the fetus the condition affects, as documented.

Official instructions as workflow

• Excludes1 — check before selecting O36.0129(2 notes)

  Coding workflow: If the documentation supports a condition named in this note, do not simply proceed with O36.0129: the two are not reported together. The one exception is when the record shows the two conditions are unrelated to each other.

  CompareZ03.7, O43.0

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

• Excludes2 — not part of O36.0129(1 note)

  Coding workflow: The conditions named in this note are not included in O36.0129. When the record documents both, both may be reported; the note is a boundary, not a prohibition.

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

The codes most likely to be picked instead of O36.0129 — 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.

• Z03.7— Excludes1 conflict (Conflict)

  Not coded here — these two are mutually exclusive.

  Not reported together with this code, except where the two conditions are documented as unrelated.

  What moves you there: Documentation of encounter for suspected maternal and fetal conditions ruled out moves the case to Z03.7; the two are not reported together unless documented as unrelated.

• O43.0— Excludes1 conflict (Conflict)

  Not coded here — these two are mutually exclusive.

  Not reported together with this code, except where the two conditions are documented as unrelated.

  What moves you there: Documentation of placental transfusion syndromes moves the case to O43.0; the two are not reported together unless documented as unrelated.

• O36.0121— Encounter relationship (Review)

  Same underlying diagnosis, different encounter phase.

  The same diagnosis at a different phase of care; one encounter takes one 7th character.

  What moves you there: Documentation of a fetus 1 moves the case to O36.0121.

• O77— Excludes2 relationship (Informational)

  Distinct conditions — both may be reported.

  A distinct condition — both may be reported when both are documented.

  What moves you there: Documentation of labor and delivery complicated by fetal stress adds O77; it is not part of this code and both may be reported when both are documented.

Decision Points

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

1. A 7th character applies in this family. Confirm the documented encounter matches the character assigned. See the official 7th-character definitions and this code’s variants
2. 2 Excludes1 entries — codes named there are generally not reported together with this code (Guidelines I.A.12.a). See the Excludes1 notes
3. 1 Excludes2 entry — 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.

Verify Before Coding

• Age-restricted: the Medicare Code Editor lists this as a maternity (age 9-64) diagnosis; other ages are presumed incorrect.
• CC as a secondary diagnosis (FY2026). Can raise the stay's MS-DRG severity tier.

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.

CC — Complication or Comorbidity. Reported as a secondary diagnosis, this code raises the stay's MS-DRG severity tier — except when the principal diagnosis is one of 42 clinically related codes on its CMS exclusion list.

Named in the grouper logic of 6 MS-DRGs: DRG 817 (MDC 14), DRG 818 (MDC 14), DRG 819 (MDC 14), DRG 831 (MDC 14), DRG 832 (MDC 14), DRG 833 (MDC 14).

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