N61 — Inflammatory disorders of breast
Is N61 billable?
No — N61 is a non-billable header code. N61 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 6 billable codes beneath N61.
