# LqSegment

`LqSegment` models the X12 LQ form-identification-code segment, used in 837/277 transactions to attach a coded remark or claim-status form reference to a claim or service line.

## Purpose
- Represents the LQ segment identity via `SegmentId` returning the literal `"LQ"` ([BR-020](../../business-rules.md#br-020-first-element-is-the-segment-identifier)).
- Carries `RemarkCode` identifying the code list/qualifier in use, paired with `IndustryCode`, the specific remark/form code value.

## 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 `"LQ"`. |
| RemarkCode | `string RemarkCode { get; set; }` | The code list qualifier for the remark/form reference (LQ01), element 1. |
| IndustryCode | `string IndustryCode { get; set; }` | The specific remark/industry code value (LQ02), element 2. |
| Build | `IEdiSegment Build()` | Creates a `SegmentBuilder("LQ")` and adds `RemarkCode` and `IndustryCode` at elements 1-2, returning the built segment. |
| Fill | `void Fill(IEdiSegment segment)` | Reads elements 1-2 via `GetChildValue` into `RemarkCode` and `IndustryCode`. |
| Parse | `static LqSegment Parse(IEdiSegment segment)` | Instantiates a new `LqSegment`, calls `Fill(segment)` on it, and returns it. |
