Not billable

Is O63 billable?

No — O63 is a non-billable header code. O63 groups more specific codes and cannot be submitted on a claim. A valid ICD-10-CM code must be reported at the highest level of specificity available in its branch. Select one of the 4 billable codes beneath O63.

Excludes1 — never code together — inherited from Chapter 15

The conditions below can never be reported together with O63 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 O63 to fully describe the condition. O63 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 O63, but a patient may have both at the same time. When documentation supports it, O63 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)
