Sv2Segment

Sv2Segment models the X12 SV2 institutional service-line segment, used in 837I claim transactions to carry a single billed institutional service line: a revenue code, the procedure/service code (inherited from SvSegmentBase), the charge amount, unit type, and quantity. It is inbound-only in this library: Build() throws NotImplementedException (BR-054).

Purpose

• Represents the SV2 segment identity via SegmentId returning the literal "SV2" (BR-020).
• Carries RevenueCode, ChargeAmount, UnitTypeCode, and ServiceQuantity describing the billed institutional service line.
• Is inbound-only: Fill(IEdiSegment) populates the object from a parsed segment, but Build() throws NotImplementedException (BR-054).

Context

• Namespace: SAIF.Common.Files.Edi.Segments
• Assembly/package: SAIF.Framework.Common.Files

Public members

Member	Signature	Purpose
SegmentId	string SegmentId { get; }	Returns the literal X12 segment identifier "SV2".
RevenueCode	string RevenueCode { get; set; }	The revenue code for the institutional service line (SV201), element 1.
ChargeAmount	decimal ChargeAmount { get; set; }	The charge amount for the service line (SV203), element 3.
UnitTypeCode	string UnitTypeCode { get; set; }	The unit-of-measure code for ServiceQuantity (SV204), element 4.
ServiceQuantity	decimal ServiceQuantity { get; set; }	The quantity of units billed for the service (SV205), element 5.
Build	IEdiSegment Build()	Always throws NotImplementedException; outbound SV2 generation is not supported (BR-054).
Fill	void Fill(IEdiSegment segment)	Reads RevenueCode at element 1; reads ServiceCode directly from element 2 if it is a plain data element, or via FillServiceCode if it is a composite; reads ChargeAmount and ServiceQuantity as decimal at elements 3 and 5, and UnitTypeCode at element 4.
Parse	static Sv2Segment Parse(IEdiSegment segment)	Instantiates a new Sv2Segment, calls Fill(segment) on it, and returns it.

Inherited public members

Members in this section are inherited from SvSegmentBase in SAIF.Framework.Common.Files. They are available on this type through inheritance.

Member	Signature	Purpose	Origin
Qualifier	string Qualifier { get; set; }	The procedure-code qualifier identifying the coding system in use, composite sub-element 1.	SAIF.Framework.Common.Files — SvSegmentBase
ServiceCode	string ServiceCode { get; set; }	The procedure/service code value, either read directly from a plain element 2 or from composite sub-element 2.	SAIF.Framework.Common.Files — SvSegmentBase
ServiceModifierCode1	string ServiceModifierCode1 { get; set; }	The first of up to four procedure modifier codes, composite sub-element 3.	SAIF.Framework.Common.Files — SvSegmentBase
ServiceModifierCode2	string ServiceModifierCode2 { get; set; }	The second procedure modifier code, composite sub-element 4.	SAIF.Framework.Common.Files — SvSegmentBase
ServiceModifierCode3	string ServiceModifierCode3 { get; set; }	The third procedure modifier code, composite sub-element 5.	SAIF.Framework.Common.Files — SvSegmentBase
ServiceModifierCode4	string ServiceModifierCode4 { get; set; }	The fourth procedure modifier code, composite sub-element 6.	SAIF.Framework.Common.Files — SvSegmentBase
ServiceDescription	string ServiceDescription { get; set; }	A free-text description of the procedure, composite sub-element 7.	SAIF.Framework.Common.Files — SvSegmentBase
BuildElement	EdiCompositeDataElement BuildElement()	Constructs a composite element with Qualifier/ServiceCode and the four modifier codes.	SAIF.Framework.Common.Files — SvSegmentBase
FillServiceCode	void FillServiceCode(IEdiCompositeDataElement element)	Reads sub-elements 1-7 of a composite element into Qualifier, ServiceCode, the four modifier codes, and ServiceDescription.	SAIF.Framework.Common.Files — SvSegmentBase

Behavioral notes

• Element position SV202 is skipped entirely (used for the procedure/service code composite itself, mapped via ServiceCode/FillServiceCode), and elements SV206-SV210 are read by neither Build() nor Fill(), per an explicit code comment*.

Constraints and usage notes

• Any caller invoking Build() on an Sv2Segment receives a NotImplementedException rather than a built segment (BR-054).

Note: Statements marked with * were inferred from code structure, naming conventions, or contextual evidence where direct confirmation was not available in source artifacts.
