Transaction Set Purpose Code

NSF Reference: AA0-23.0

Original

Original transmission are claims/encounters which have never been sent to the receiver. Generally, nearly all transmissions to a payer entity (as the ultimate destination of the transaction) are original.

Reissue

In the case where a transmission was disrupted, the receiver can request that the batch be sent again. Use ‘‘Reissue’’ when resending transmission batches that have been previously sent.

BHT03	127	Reference Identification Description: Reference information as defined for a particular Transaction Set or as specified by the Reference Identification Qualifier Industry: Originator Application Transaction Identifier NSF Reference: AA0-05.0 The inventory file number of the transmission assigned by the submitter’s system. This number operates as a batch control number. It may or may not be identical to the number carried in the ST02.	O	AN	1/30	Required
BHT04	373	Date Description: Date expressed as CCYYMMDD Industry: Transaction Set Creation Date NSF Reference: AA0-15.0 Use this date to identify the date on which the submitter created the file.	O	DT	8/8	Required
BHT05	337	Time Description: Time expressed in 24-hour clock time as follows: HHMM, or HHMMSS, or HHMMSSD, or HHMMSSDD, where H = hours (00-23), M = minutes (00-59), S = integer seconds (00-59) and DD = decimal seconds; decimal seconds are expressed as follows: D = tenths (0-9) and DD = hundredths (00-99) Industry: Transaction Set Creation Time NSF Reference: AA0-16.0 Use the time to identify the time of day that the submitter created the file.	O	TM	4/8	Required
BHT06	640	Transaction Type Code Description: Code specifying the type of transaction Industry: Claim or Encounter Identifier Alias: Claim or Encounter Indicator Although this element is required, submitters are not necessarily required to accurately batch claims and encounters at this level. Generally, CH is used for claims and RP is used for encounters. However, use “CH” if an ST-SE envelope contains both claims and encounters. Some trading partner agreements may specify using only one code.	O	ID	2/2	Required

Chargeable

Use this code when the transmission contains only Fee-for-service claims or claims with at least one chargeable item. If it is not clear whether a transaction is a claim or an encounter, the developers of this implementation guide recommend submitting the transaction as a claim.

Reporting

Use RP when the entire ST-SE envelope contains
encounter transmissions.
Use RP when the transmission is being sent to an entity (usually not a payer or a normal provider-payer transmission intermediary) for purposes other than adjudication of a claim. Such an entity could be a state health data agency which is using the 837 for health data reporting purposes.
