This code system http://hl7.org/fhir/adverse-event-causality-assess http://terminology.hl7.org/CodeSystem/adverse-event-causality-assess defines the following codes:

Code Display Definition
certain assess1 Certain i) Event or laboratory test abnormality, with plausible time relationship to drug intake; ii) Cannot be explained by disease or other drugs; iii) Response to withdrawal plausible (pharmacologically, pathologically); iv) Event definitive pharmacologically or phenomenologically (i.e. an objective and specific medical disorder or a recognized pharmacological phenomenon); or v) Re-challenge satisfactory, if necessary.
probably-likely assess1 placeholder Probably/Likely i) Event or laboratory test abnormality, with reasonable time relationship to drug intake; ii) Unlikely to be attributed to disease or other drugs; iii) Response to withdrawal clinically reasonable; or iv) Re-challenge not required.
possible assess2 Possible i) Event or laboratory test abnormality, with reasonable time relationship to drug intake; ii) Could also be explained by disease or other drugs; or iii) Information on drug withdrawal may be lacking or unclear.
unlikely assess2 placeholder Unlikely i) Event or laboratory test abnormality, with a time to drug intake that makes a relationship improbable (but not impossible); or ii) Disease or other drugs provide plausible explanations.
conditional-classified Conditional/Classified i) Event or laboratory test abnormality; ii) More data for proper assessment needed; or iii) Additional data under examination.
unassessable-unclassifiable Unassessable/Unclassifiable i) Report suggesting an adverse reaction; ii) Cannot be judged because information is insufficient or contradictory; or iii) Data cannot be supplemented or verified.

Explanation of the columns that may appear on this page:

Level A few code lists that FHIR defines are hierarchical - each code is assigned a level. In this scheme, some codes are under other codes, and imply that the code they are under also applies See Code System for further information.
