O72.1 ICD-10-CM Code: Other immediate postpartum hemorrhage

Coding instructions

Official Tabular Instructional Notes: the inclusion, exclusion and sequencing notes published for O72.1 in the official ICD-10-CM tabular list, quoted as published.

Notes without a marker are published on O72.1 itself; “inherited from” names the category or block whose note applies here.

Coder workflow for O72.1

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

Before you code O72.1

1. “Other” (NEC) means the condition is specified in the record but no dedicated code captures it. Confirm the documented form is not one a sibling code names before settling on O72.1; if the record states no specifics at all, the unspecified sibling applies instead. “Other” codes are for documented conditions the classification gives no specific code; “unspecified” codes are for records lacking the detail (Guidelines I.A.9.a, I.A.9.b).

   ReviewO72.0, O72.2, O72.3

   See the relationships section · Guide: Other vs unspecified (NEC vs NOS) →

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 O72.1. 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 O72.1’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.

   ReviewO62.2, O75.89

Consider O72.1. 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).

Any detail beyond this code’s title

What the record states that a more specific sibling code would capture — or its absence, which itself supports the unspecified code.

Official instructions as workflow

• Excludes1 — check before selecting O72.1(3 notes)

  Coding workflow: If the documentation supports a condition named in this note, do not simply proceed with O72.1: the two are not reported together. The one exception is when the record shows the two conditions are unrelated to each other.

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 (7)

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.

• Atonia, atony, atonic, uterus (during labor), postpartum (with hemorrhage)
• Atonia, atony, atonic, uterus (during labor), with hemorrhage (postpartum)
• Bleeding, atonic, following delivery
• Delivery (childbirth) (labor), complicated, by, hemorrhage (uterine), postpartum NEC (atonic) (immediate)
• Hemorrhage, hemorrhagic (concealed), postpartum NEC (following delivery of placenta)
• Metrorrhagia, postpartum NEC (atonic) (following delivery of placenta)
• Puerperal, puerperium (complicated by, complications), hemorrhage

Don’t confuse O72.1 with…

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

The codes most likely to be picked instead of O72.1 — 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.

• O62.2— 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 uterine atony NOS moves the case to O62.2; the two are not reported together unless documented as unrelated.

• O75.89— 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 postpartum atony of uterus without hemorrhage moves the case to O75.89; the two are not reported together unless documented as unrelated.

  Full comparison: O72.1 vs O75.89 →

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.

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.

Relationships & Classification

MedCoder structured relationships — computed from published CMS and AHRQ datasets

Other codes that name O72.1 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: O62.2 — Other uterine inertia.

These codes’ tabular lists mark this diagnosis as mutually exclusive — not reported together unless the conditions are documented as unrelated.

Referenced by 1 Excludes2 note: O67 — Labor and delivery complicated by intrapartum hemorrhage, not elsewhere classified (via O72.-).

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: 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 250 clinically related codes on its CMS exclusion list.

Named in the grouper logic of 2 MS-DRGs: DRG 769 (MDC 14), DRG 776 (MDC 14).

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

Clinical classification (AHRQ CCSR):PRG027 — Complications specified during the puerperium (default); PRG010 — Hemorrhage after first trimester.
