MS-DRG 998 — PRINCIPAL DIAGNOSIS INVALID AS DISCHARGE DIAGNOSIS

Working the claim behind this DRG

A DRG is assigned from the diagnoses and procedures already on the claim, so the questions that decide MS-DRG 998 are coding questions. Look the principal diagnosis up in the full ICD-10-CM tabular list with its Excludes1 and “code first” notes attached, or start from the condition instead of the code in the codes-by-condition index. For the secondary diagnoses that move a case between the with-MCC, with-CC and without-CC/MCC splits, paste the whole set into the free claim scrubber and see which pairs collide before the claim goes out — no account, no card.

The supplies, drugs and devices billed alongside an inpatient stay are HCPCS Level II, listed in full at HCPCS by section. If the claim comes back rejected, the denial code index explains what each CARC actually means and what to do about it, and the decision guides walk the sequencing calls that most often cause one — sepsis and diabetes above all.

Every one of those is free and needs no account. This page is the payment table: it says what MS-DRG 998 is worth. Which medical DRG a set of diagnoses lands in is the workspace’s DRG impact check, from the CMS CC/MCC lists; it does not group surgical cases.
