Concepts

This case-sensitive code system `http://terminology.hl7.org/v2plusvocab/CodeSystem/orderControlCodeReason` defines the following codes:

Code | Display | Definition | version introduced | comment, to suppress IG-publisher warning, to be replaced with standard later | usage | modified
CO | Cost | Order changed based on cost | 2.9 | In an order replacement context, this would accompany proposal of a similar but lower cost order |  | 2022-08-25
ST | Specimen Type | Incorrect specimen type submitted for the requested test | 2.9 | Order placer may accept, cancel and replace, or choose other testing. | Recommend testing that can use the submitted specimen type | 2022-08-25
SV | Specimen Volume | Provided specimen volume inadequate for testing | 2.9 | The question is how to use the available specimen. The Order Placer may choose a different subset of tests. | Recommend a subset of ordered tests appropriate for volume | 2022-08-25
UN | Unavailable test | Requested test not available | 2.9 | In an order replacement context, an alternative might be proposed. |  | 2022-08-25
