- Coma › with › motor response › abnormal flexure posturing to pain or noxious stimuli
- Coma › with › motor response › flexion/decorticate posturing
- Coma › with › motor response › score of › 3
Inclusion terms
Alternative wording in documentation that is classified to R40.233.
- Abnormal flexure posturing to pain or noxious stimuli (2-5 years of age)
- Coma scale motor score of 3
- Flexion/decorticate posturing (< 2 years of age)
Excludes1 — never code together — inherited from R40
The conditions below can never be reported together with R40.233 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
Code first — inherited from R40.2
The underlying condition below must be sequenced before R40.233. R40.233 describes a manifestation and cannot be the principal or first-listed diagnosis.
Excludes2 — not included here — inherited from Chapter 18
The conditions below are not part of R40.233, but a patient may have both at the same time. When documentation supports it, R40.233 and the excluded code may both be reported.
Excludes2 — not included here — inherited from R40-R46
The conditions below are not part of R40.233, but a patient may have both at the same time. When documentation supports it, R40.233 and the excluded code may both be reported.
- symptoms and signs constituting part of a pattern of mental disorder (F01-F99)
