Which MS-DRGs does C96.A group to?

C96.A sits in MDC Pre 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.

  • 011Tracheostomy for Face, Mouth and Neck Diagnoses or Laryngectomy with MCCsurgical
  • 012Tracheostomy for Face, Mouth and Neck Diagnoses or Laryngectomy with CCsurgical
  • 013Tracheostomy for Face, Mouth and Neck Diagnoses or Laryngectomy without CC/MCCsurgical

As a secondary diagnosis, C96.A is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.

Inclusion terms

Alternative wording in documentation that is classified to C96.A.

  • Malignant histiocytosis

Excludes1 — never code together — inherited from C96

The conditions below can never be reported together with C96.A 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 other malignant neoplasms of lymphoid, hematopoietic and related tissues (Z85.79)

Excludes2 — not included here — inherited from C81-C96

The conditions below are not part of C96.A, but a patient may have both at the same time. When documentation supports it, C96.A 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 C96.A existed?

C96.A 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.
