J35.03

Billable

Chronic tonsillitis and adenoiditis

This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).

What This Code Means

Long-term inflammation of both the tonsils and adenoids, causing persistent throat symptoms and swelling.

Coding Tips

  • •Verify documentation specifies both tonsillitis AND adenoiditis; if only one structure is affected, use different codes
  • •Confirm the condition is chronic (long-standing) rather than acute to support this code selection
