Which MS-DRGs does C84.7A group to?

C84.7A 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.

  • 820Lymphoma and Leukemia with Major O.R. Procedures with MCCsurgical
  • 821Lymphoma and Leukemia with Major O.R. Procedures with CCsurgical
  • 822Lymphoma and Leukemia with Major O.R. Procedures without CC/MCCsurgical

As a secondary diagnosis, C84.7A is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.

How is C84.7A listed in the Alphabetic Index?

These are the routes through the Alphabetic Index that lead to C84.7A. They show the wording a clinician may have documented, which often differs from the Tabular description.

  • Lymphoma › anaplastic large cell › breast implant associated (of) (malignant)

Use additional code

Report an additional code alongside C84.7A to fully describe the condition. C84.7A is sequenced first.

  • code to identify:
  • breast implant status (Z98.82)
  • personal history of breast implant removal (Z98.86)

Inclusion terms

Alternative wording in documentation that is classified to C84.7A.

  • Breast implant associated anaplastic large cell lymphoma (BIA-ALCL)

Excludes1 — never code together — inherited from C84

The conditions below can never be reported together with C84.7A on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

  • personal history of non-Hodgkin lymphoma (Z85.72)

Excludes1 — never code together — inherited from C84.7

The conditions below can never be reported together with C84.7A on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

  • primary cutaneous CD30-positive T-cell proliferations (C86.6-)

Excludes2 — not included here — inherited from C81-C96

The conditions below are not part of C84.7A, but a patient may have both at the same time. When documentation supports it, C84.7A and the excluded code may both be reported.

  • Kaposi's sarcoma of lymph nodes (C46.3)
  • secondary and unspecified neoplasm of lymph nodes (C77.-)
  • secondary neoplasm of bone marrow (C79.52)
  • secondary neoplasm of spleen (C78.89)

How long has C84.7A existed?

C84.7A first appears in FY2022.

Derived from the official order files for FY2016–FY2026. FY2017 and FY2020 publish no order file, so those years are not covered.
