About Z43
Z43 is the ICD-10-CM diagnosis code for encounter for attention to artificial openings. It belongs to block Z40-Z53 (Encounters for other specific health care) and chapter 21 (factors influencing health status and contact with health services). It is a header code, so it can't be reported by itself; one of its 10 subcodes must be used instead.
To report this condition, pick the subcode that matches the documentation: Z43.0 (tracheostomy), Z43.1 (gastrostomy), Z43.2 (ileostomy), Z43.3 (colostomy), Z43.4 (tract), Z43.5 (cystostomy), Z43.6 (tract), Z43.7 (vagina) and 2 more.
Don't report Z43 together with the conditions in its Excludes1 note: complications of external stoma (J95.0-, K94.-, N99.5-).
The conditions in its Excludes2 note aren't part of Z43, but may be coded alongside it if the patient has both: fitting and adjustment of prosthetic and other devices (Z44-Z46).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
