Coding references

Ear, nose and throat: the codes and the rules.

Three tables for a ENT practice, each one a coder can check against the 2025 CMS and ICD-10-CM files, and the notes that come up every week.

2025 files

Reference, not billing advice. The practice's coder confirms every code before a claim goes out.

The tables.

The notes a coder repeats.

  • Nasal endoscopy on the same day as a visit needs the visit to be separately identifiable (modifier 25); the scope alone is not a visit.
  • Cerumen removal (69210) is unilateral; the payer's policy decides whether the second ear takes modifier 50 or is not paid.
  • Audiology codes are billed by the audiologist under their own NPI where the practice employs one.

Screening forms your clinicians approve, the on-call paged with answers, and every call booked or handed back as a task.
