This code system http://terminology.hl7.org/CodeSystem/v2-0472 defines the following codes:
Code | Display | Definition | V2 Table Status | V2 Concept Comment | V2 Concept Comment As Published |
S | Synchronous | Synchronous | A | Do the next specification after this one (unless otherwise constrained by the following fields: TQ1-7-start date/time and TQ1-8-end date/time). An "S" specification implies that the second timing sequence follows the first, e.g., when a service request is written to measure blood pressure Q15 minutes for the 1st hour, then every 2 hours for the next day. | Do the next specification after this one (unless otherwise constrained by the following fields: TQ1-7-start date/time and TQ1-8-end date/time).

A | Asynchronous | Asynchronous | A | Do the next specification in parallel with this one (unless otherwise constrained by the following fields: TQ1-7-start date/time and TQ1-8-end date/time). The conjunction of "A" specifies two parallel instructions, as are sometimes used in medication, e.g., prednisone given at 1 tab on Monday, Wednesday, Friday, and at 1/2 tab on Tuesday, Thursday, Saturday, Sunday. | Do the next specification in parallel with this one (unless otherwise constrained by the following fields: TQ1-7-start date/time and TQ1-8-end date/time).

C | Actuation Time | Actuation Time | A | It will be followed by a completion time for the service. This code allows one to distinguish between the time and priority at which a service should be actuated (e.g., blood should be drawn) and the time and priority at which a service should be completed (e.g., results should be reported). | It will be followed by a completion time for the service.
