What Medicare edits apply to T81.12XA?
The Medicare Code Editor screens inpatient claims before they are grouped. These edits name T81.12XA directly.
CMS will reject this code as the principal diagnosis on an inpatient claim. It describes something other than the condition chiefly responsible for the admission.
Which MS-DRGs does T81.12XA group to?
T81.12XA sits in MDC 15 and helps define the logic of 1 MS-DRG (version 44, FY2027). Which one a stay actually groups to also depends on procedures and secondary diagnoses.

Code first
The underlying condition below must be sequenced before T81.12XA. T81.12XA describes a manifestation and cannot be the principal or first-listed diagnosis.
- underlying infection
Use additional code
Report an additional code alongside T81.12XA to fully describe the condition. T81.12XA is sequenced first.
- code, to identify any associated acute organ dysfunction, if applicable
Inclusion terms
Alternative wording in documentation that is classified to T81.12XA.
- Postprocedural endotoxic shock resulting from a procedure, not elsewhere classified
- Postprocedural gram-negative shock resulting from a procedure, not elsewhere classified
