ODT - Diet Tray Instructions Segment

This segment addresses tray instructions. These are independent of diet codes, supplements, and preferences and therefore get separate order numbers.

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: When blank, the modifier applies to all service periods. This field allows you to designate one or more of the feeding periods during a day by combining the codes as needed. It can also combine with quantity/timing to give such information as which service period the order belongs with. This field is identical in meaning with ODS-2-service period. See section 4.8.1.2, "ODS-2 Service Period (CWE) 00270," for further details. Refer to Table 0629 - Service Period in Chapter 2C for valid values.

ODT-3: Text Instruction (ST) 00272
