ODT-1: Tray Type (CWE) 00273

Definition: This field defines the type of dietary tray. Refer To HL7 Table 0160 - Tray Type in Chapter 2C, Code Tables, for valid entries.

Tray specifications are useful for early and late tray delivery in cases where a patient undergoes a procedure during normal feeding times. Tray specifications can also be used for guest trays, no trays, and messages. The value MSG means the ODT segment does not specify the type of tray but provides additional information about an existing tray. This information is found in ODT-3-text instruction.

ODT-2: Service Period (CWE) 00270

(Definition from ODS.2 in Ch. 4)

Definition: When blank, the modifier applies to all service periods. Diet orders, for example, typically apply to all service periods. This field usually specifies supplements.
