P28.10 — Unspecified atelectasis of newborn
Is P28.10 billable?
Yes, but P28.10 is an unspecified code. P28.10 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, P28.10 is an unspecified or catch-all code. Payers apply additional scrutiny to unspecified codes and many deny them when the medical record supports a more specific option, so check the documentation before selecting P28.10 — the more specific alternatives are listed below.
