The only place in this corpus that prices an inpatient admission: the payer MRF corpus is fee-for-service throughout and carries no DRG rows in any payer-month. `method\n    [TEXT CUT AFTER 600 OF 1512 CHARACTERS. The whole span is bytes 0-1512 of this document's normalized text.]\n\nSOURCE DOCUMENTS:\n  53 hospital-price-transparency  sha256 b0c2f9fe6a6309707672410b02980a8a2520237cddf3804aa0604ffee9fb1771\n\nThis answer is stated against numbering e492637bb79c8fa9. A claim about any node id above is only true against that numbering, so name it.\nThe TEXT under a chunk is that chunk's indexed span, verbatim, at the byte offsets named beside it. You may quote it and say the document reads this way there. You may not say the chunk is about your query, answers it, or supports your sentence: the retrieval put the span in front of you and reading it is not evidence that the ranking was right.\n\nNO READING IS ATTACHED. These fields carry no interpretation, and this world does not supply one unasked. To obtain a reading, and to find out whether what you are about to write is supported, call judgement_check with receipt \"r2976\" and the claims you intend to make. A claim written without checking it is a claim this world did not license.\n\nIf you can write your claim as an expression over the figures above, for example {\"op\": \"<=\", \"left\": \"anchor.nodes[0]\", \"right\": 12, \"scope\": \"marginal\"}, call claim_check with the same receipt instead. It decides by entailment over those figures and never reads your sentence, so it answers the same way in any language. The two checks are alternatives and neither falls back to the other."
