What is this code?

When is it used?

  • May be used when a clinician documents preterm [premature] newborn [other] in a patient's medical record.
  • May appear in hospital records, claims, referrals, and clinical documentation.

What it does not mean

  • A medical code should not be treated as a substitute for a doctor's diagnosis or advice.
  • This entry may represent a broader category rather than the most specific billable code.
