Which MS-DRGs does T86.5 group to?

T86.5 sits in MDC 21 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.

  • 919Complications of Treatment with MCCmedical
  • 920Complications of Treatment with CCmedical
  • 921Complications of Treatment without CC/MCCmedical

As a secondary diagnosis, T86.5 is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.

How is T86.5 listed in the Alphabetic Index?

  • Failure, failed › transplant › stem cell

Inclusion terms

Alternative wording in documentation that is classified to T86.5.

  • Complications from stem cells from peripheral blood
  • Complications from stem cells from umbilical cord

Use additional code — inherited from Chapter 19

Report an additional code alongside T86.5 to fully describe the condition. T86.5 is sequenced first.

  • code to identify any retained foreign body, if applicable (Z18.-)

Use additional code — inherited from T80-T88

Report an additional code alongside T86.5 to fully describe the condition. T86.5 is sequenced first.

  • code for adverse effect, if applicable, to identify drug (T36-T50 with fifth or sixth character 5)
  • code(s) to identify the specified condition resulting from the complication
  • code to identify devices involved and details of circumstances (Y62-Y82)

Use additional code — inherited from T86

Report an additional code alongside T86.5 to fully describe the condition. T86.5 is sequenced first.

How long has T86.5 existed?

T86.5 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.
