What Medicare edits apply to K67?
The Medicare Code Editor screens inpatient claims before they are grouped. These edits name K67 directly.
This code describes a manifestation of an underlying disease. The underlying condition must be sequenced before it, so it can never be the principal or first-listed diagnosis.
Which MS-DRGs does K67 group to?
K67 sits in MDC 06 and helps define the logic of 3 MS-DRGs (version 44, FY2027). Which one a stay actually groups to also depends on procedures and secondary diagnoses.
- 371Major Gastrointestinal Disorders and Peritoneal Infections with MCCmedical
- 372Major Gastrointestinal Disorders and Peritoneal Infections with CCmedical
- 373Major Gastrointestinal Disorders and Peritoneal Infections without CC/MCCmedical
As a secondary diagnosis, K67 is a major complication or comorbidity (MCC), which can move a stay into a higher-paying DRG.
How is K67 listed in the Alphabetic Index?
These are the routes through the Alphabetic Index that lead to K67. They show the wording a clinician may have documented, which often differs from the Tabular description.
- Granuloma › peritoneum › due to ova of helminths NOS
- Peritonitis › syphilitic › congenital (adhesive) (bacterial) (fibrinous) (hemorrhagic) (idiopathic) (localized) (perforative) (primary) (with adhesions) (with effusion)
Excludes1 — never code together
The conditions below can never be reported together with K67 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
Code first
The underlying condition below must be sequenced before K67. K67 describes a manifestation and cannot be the principal or first-listed diagnosis.
Excludes2 — not included here — inherited from Chapter 11
The conditions below are not part of K67, but a patient may have both at the same time. When documentation supports it, K67 and the excluded code may both be reported.
- certain conditions originating in the perinatal period (P04-P96)
- certain infectious and parasitic diseases (A00-B99)
- complications of pregnancy, childbirth and the puerperium (O00-O9A)
- congenital malformations, deformations and chromosomal abnormalities (Q00-Q99)
- endocrine, nutritional and metabolic diseases (E00-E88)
- injury, poisoning and certain other consequences of external causes (S00-T88)
- neoplasms (C00-D49)
- symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified (R00-R94)
How long has K67 existed?
K67 has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.
Derived from the official order files for FY2016–FY2026. FY2017 and FY2020 publish no order file, so those years are not covered.
