Variable: REMIT_835_LOOP_2000
constREMIT_835_LOOP_2000:LoopSpec
835 Loop 2000 - Header Number. Triggered by LX. Nests Loop 2100.
Cited as Loop 2000 in TR3 X221A1; situational because some payers
(notably Medicare FFS) omit the LX header entirely and ship CLP loops
directly under the transaction set header. The Phase 4 walker handles
both shapes - claims appear inside Loop 2000 if LX is present, at
top level otherwise.
Example
import { REMIT_835_LOOP_2000 } from "@cosyte/x12";
REMIT_835_LOOP_2000.trigger; // "LX"
REMIT_835_LOOP_2000.children[0]?.trigger; // "CLP" (Loop 2100)
