What Medicare edits apply to C80.2?
The Medicare Code Editor screens inpatient claims before they are grouped. These edits name C80.2 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 C80.2 group to?
C80.2 sits in MDC 17 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.
- 826Myeloproliferative Disorders or Poorly Differentiated Neoplasms with Major O.R. Procedures with MCCsurgical
- 827Myeloproliferative Disorders or Poorly Differentiated Neoplasms with Major O.R. Procedures with CCsurgical
- 828Myeloproliferative Disorders or Poorly Differentiated Neoplasms with Major O.R. Procedures without CC/MCCsurgical
As a secondary diagnosis, C80.2 is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.
How is C80.2 listed in the Alphabetic Index?
These are the routes through the Alphabetic Index that lead to C80.2. They show the wording a clinician may have documented, which often differs from the Tabular description.
- Complication › transplant › malignant neoplasm (s) (from) (of)
Code first
The underlying condition below must be sequenced before C80.2. C80.2 describes a manifestation and cannot be the principal or first-listed diagnosis.
- complication of transplanted organ (T86.-)
Use additional code
Report an additional code alongside C80.2 to fully describe the condition. C80.2 is sequenced first.
- code to identify the specific malignancy
Excludes1 — never code together — inherited from C80
The conditions below can never be reported together with C80.2 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- malignant carcinoid tumor of unspecified site (C7A.00)
- malignant neoplasm of specified multiple sites- code to each site
How long has C80.2 existed?
C80.2 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.
