O30.101 — Triplet pregnancy, unspecified number of placenta and unspecified number of amniotic sacs, first trimester

BillableUnspecifiedCC

Is O30.101 billable?

Yes, but O30.101 is an unspecified code. O30.101 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, O30.101 is an unspecified or catch-all code. Payers apply additional scrutiny to unspecified codes and many deny them when the medical record supports a more specific option, so check the documentation before selecting O30.101 — the more specific alternatives are listed below.

Which MS-DRGs does O30.101 group to?

O30.101 sits in MDC 14 and helps define the logic of 3 MS-DRGs (version 44, FY2027). Which one a stay actually groups to also depends on procedures and secondary diagnoses.

  • 817Other Antepartum Diagnoses with O.R. Procedures with MCCsurgical
  • 818Other Antepartum Diagnoses with O.R. Procedures with CCsurgical
  • 819Other Antepartum Diagnoses with O.R. Procedures without CC/MCCsurgical

As a secondary diagnosis, O30.101 is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.

Excludes1 — never code together — inherited from Chapter 15

The conditions below can never be reported together with O30.101 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

  • supervision of normal pregnancy (Z34.-)

Use additional code — inherited from Chapter 15

Report an additional code alongside O30.101 to fully describe the condition. O30.101 is sequenced first.

  • code, if applicable, from category Z3A, Weeks of gestation, to identify the specific week of the pregnancy, if known.

Excludes2 — not included here — inherited from Chapter 15

The conditions below are not part of O30.101, but a patient may have both at the same time. When documentation supports it, O30.101 and the excluded code may both be reported.

  • mental and behavioral disorders associated with the puerperium (F53.-)
  • obstetrical tetanus (A34)
  • postpartum necrosis of pituitary gland (E23.0)
  • puerperal osteomalacia (M83.0)

Code also — inherited from O30

Two codes may be needed to describe the condition fully. Whether O30.101 is sequenced first depends on the reason for the encounter.

  • any complications specific to multiple gestation

How long has O30.101 existed?

O30.101 has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.

Derived from the official order files for FY2016–FY2026. FY2017 and FY2020 publish no order file, so those years are not covered.
