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 5 more specific codes instead:

  • S99.0 Physeal fracture of calcaneus (also a header)
  • S99.1 Physeal fracture of metatarsal (also a header)
  • S99.2 Physeal fracture of phalanx of toe (also a header)
  • S99.8 Other specified injuries of ankle and foot (also a header)
  • S99.9 Unspecified injury of ankle and foot (also a header)

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.
