Umbilical polyp of newborn

This code represents a benign, often pedunculated, growth of granulation tissue or remnants of the umbilical cord lining that persists after the umbilical cord has separated in a newborn. It typically appears as a small, moist, reddish lesion at the base of the umbilicus.

Use this code for newborns diagnosed with an umbilical polyp, which is a common cause of persistent umbilical discharge or bleeding. Documentation should clearly identify the lesion as a polyp and confirm its umbilical location in a neonate.

• Differentiate from an umbilical granuloma, which is also granulation tissue but typically lacks the distinct polypoid structure.
• Ensure the patient's age is consistent with a "newborn" diagnosis (typically up to 28 days of age).
• Code any associated symptoms, such as umbilical discharge (e.g., R60.9 for unspecified edema, if applicable), as secondary diagnoses.
