Excludes1 — never code together — inherited from Chapter 15

The conditions below can never be reported together with O90.1 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 O90.1 to fully describe the condition. O90.1 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 O90.1, but a patient may have both at the same time. When documentation supports it, O90.1 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 O85-O92

The conditions below are not part of O90.1, but a patient may have both at the same time. When documentation supports it, O90.1 and the excluded code may both be reported.

  • mental and behavioral disorders associated with the puerperium (F53.-)
  • obstetrical tetanus (A34)
  • puerperal osteomalacia (M83.0)
