Cystitis

Not billableICD-10-CM diagnosis code.

This code exists but cannot be submitted on its own. It groups the more specific codes beneath it.

A category header for its whole life, FY2016 onwards. It has never been valid for submission on its own.

Submit one of these 7 more specific codes instead:

  • N30.0 Acute cystitis (also a header)
  • N30.1 Interstitial cystitis (chronic) (also a header)
  • N30.2 Other chronic cystitis (also a header)
  • N30.3 Trigonitis (also a header)
  • N30.4 Irradiation cystitis (also a header)
  • N30.8 Other cystitis (also a header)
  • N30.9 Cystitis, unspecified (also a header)

What has happened to this code

Every change the publisher made, from 2012 to now. Entries marked draft are from the pre-implementation releases: ICD-10 took effect on 1 October 2015, so nothing before FY2016 was ever valid on a claim.

  1. FY2012 Added to the draft code set draft Cystitis
