Observation Identifier
2020-01-06
Definition: This field contains a unique identifier for the observation. The format is that of the Coded Element (CWE). Example: "8625-6^P-R interval^LN". Refer to Table 0622 - Observation Identifier in Chapter 2C for valid values.
In most systems the identifier will point to a master observation table that will provide other attributes of the observation that may be used by the receiving system to process the observations it receives. A set of message segments for transmitting such master observation tables is described in Chapter 8. The relation of an observation ID to a master observation table is analogous to the relationship between a charge code (in a billing record) and the charge master.
