O35.FXX0Maternal care for other (suspected) fetal abnormality and damage, fetal musculoskeletal anomalies of trunk, not applicable or unspecified

BillableUnspecified

Is O35.FXX0 billable?

Yes, but O35.FXX0 is an unspecified code. O35.FXX0 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, O35.FXX0 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 O35.FXX0.

Which MS-DRGs does O35.FXX0 group to?

O35.FXX0 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.

How is O35.FXX0 listed in the Alphabetic Index?

The Alphabetic Index lists these routes under O35.F, the nearest indexed parent of O35.FXX0. Use them to find the family, then select the specific code.

  • Pregnancycomplicated byfetalmusculoskeletal anomaliestrunk (single) (uterine)

Excludes2 — not included here

The conditions below are not part of O35.FXX0, but a patient may have both at the same time. When documentation supports it, O35.FXX0 and the excluded code may both be reported.

  • maternal care for other (suspected) fetal abnormality and damage, fetal lower extremities anomalies (O35.H)
  • maternal care for other (suspected) fetal abnormality and damage, fetal upper extremities anomalies (O35.G)

Excludes1 — never code together — inherited from Chapter 15

The conditions below can never be reported together with O35.FXX0 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.-)

Excludes1 — never code together — inherited from O35

The conditions below can never be reported together with O35.FXX0 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

  • encounter for suspected maternal and fetal conditions ruled out (Z03.7-)

Use additional code — inherited from Chapter 15

Report an additional code alongside O35.FXX0 to fully describe the condition. O35.FXX0 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 O35.FXX0, but a patient may have both at the same time. When documentation supports it, O35.FXX0 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)

Excludes2 — not included here — inherited from O35.F

The conditions below are not part of O35.FXX0, but a patient may have both at the same time. When documentation supports it, O35.FXX0 and the excluded code may both be reported.

  • maternal care for other (suspected) fetal abnormality and damage, fetal lower extremities anomalies (O35.H)
  • maternal care for other (suspected) fetal abnormality and damage, fetal upper extremities anomalies (O35.G)

Code also — inherited from O35

Two codes may be needed to describe the condition fully. Whether O35.FXX0 is sequenced first depends on the reason for the encounter.

  • any associated maternal condition
