Code first
The underlying condition below must be sequenced before X00. X00 describes a manifestation and cannot be the principal or first-listed diagnosis.
- any associated cataclysm
Excludes2 — not included here
The conditions below are not part of X00, but a patient may have both at the same time. When documentation supports it, X00 and the excluded code may both be reported.
Includes
Conditions classified to X00.
- conflagration in building or structure
Excludes1 — never code together — inherited from X00-X08
The conditions below can never be reported together with X00 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- arson (X97)
Excludes2 — not included here — inherited from X00-X08
The conditions below are not part of X00, but a patient may have both at the same time. When documentation supports it, X00 and the excluded code may both be reported.
