T86.899 — Unspecified complication of other transplanted tissue

BillableUnspecifiedCC

Is T86.899 billable?

Yes, but T86.899 is an unspecified code. T86.899 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, T86.899 is an unspecified or catch-all code. Payers apply additional scrutiny to unspecified codes and many deny them when the medical record supports a more specific option, so check the documentation before selecting T86.899 — the more specific alternatives are listed below.

Which MS-DRGs does T86.899 group to?

T86.899 sits in MDC 07 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.

  • 438Disorders of Pancreas Except Malignancy with MCCmedical
  • 439Disorders of Pancreas Except Malignancy with CCmedical
  • 440Disorders of Pancreas Except Malignancy without CC/MCCmedical

As a secondary diagnosis, T86.899 is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.

How is T86.899 listed in the Alphabetic Index?

Excludes2 — not included here — inherited from T80-T88

The conditions below are not part of T86.899, but a patient may have both at the same time. When documentation supports it, T86.899 and the excluded code may both be reported.

How long has T86.899 existed?

T86.899 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.
