Which MS-DRGs does T86.810 group to?

T86.810 sits in MDC 04 and helps define the logic of 2 MS-DRGs (version 44, FY2027). Which one a stay actually groups to also depends on procedures and secondary diagnoses.

  • 205Other Respiratory System Diagnoses with MCCmedical
  • 206Other Respiratory System Diagnoses without MCCmedical

As a secondary diagnosis, T86.810 is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.

How is T86.810 listed in the Alphabetic Index?

These are the routes through the Alphabetic Index that lead to T86.810. They show the wording a clinician may have documented, which often differs from the Tabular description.

  • Rejection › transplant › lung
  • Complication › transplant › lung › rejection (s) (from) (of)

Excludes1 — never code together — inherited from T86.81

The conditions below can never be reported together with T86.810 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

  • complication of heart-lung transplant (T86.3-)

Use additional code — inherited from Chapter 19

Report an additional code alongside T86.810 to fully describe the condition. T86.810 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 T86.810 to fully describe the condition. T86.810 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 T86.810 to fully describe the condition. T86.810 is sequenced first.

  • code to identify other transplant complications, such as:
  • graft-versus-host disease (D89.81-)
  • malignancy associated with organ transplant (C80.2)
  • post-transplant lymphoproliferative disorders (PTLD) (D47.Z1)

Excludes2 — not included here — inherited from Chapter 19

The conditions below are not part of T86.810, but a patient may have both at the same time. When documentation supports it, T86.810 and the excluded code may both be reported.

  • birth trauma (P10-P15)
  • obstetric trauma (O70-O71)

Excludes2 — not included here — inherited from T80-T88

The conditions below are not part of T86.810, but a patient may have both at the same time. When documentation supports it, T86.810 and the excluded code may both be reported.

  • any encounters with medical care for postprocedural conditions in which no complications are present, such as:
  • artificial opening status (Z93.-)
  • closure of external stoma (Z43.-)
  • fitting and adjustment of external prosthetic device (Z44.-)
  • burns and corrosions from local applications and irradiation (T20-T32)
  • complications of surgical procedures during pregnancy, childbirth and the puerperium (O00-O9A)
  • mechanical complication of respirator [ventilator] (J95.850)
  • poisoning and toxic effects of drugs and chemicals (T36-T65 with fifth or sixth character 1-4 or 6)
  • postprocedural fever (R50.82)
  • specified complications classified elsewhere, such as:
  • cerebrospinal fluid leak from spinal puncture (G97.0)
  • colostomy malfunction (K94.0-)
  • disorders of fluid and electrolyte imbalance (E86-E87)
  • functional disturbances following cardiac surgery (I97.0-I97.1)
  • intraoperative and postprocedural complications of specified body systems (D78.-, E36.-, E89.-, G97.3-, G97.4, H59.3-, H59.-, H95.2-, H95.3, I97.4-, I97.5, J95.6-, J95.7, K91.6-, L76.-, M96.-, N99.-)
  • ostomy complications (J95.0-, K94.-, N99.5-)
  • postgastric surgery syndromes (K91.1)
  • postlaminectomy syndrome NEC (M96.1)
  • postmastectomy lymphedema syndrome (I97.2)
  • postsurgical blind-loop syndrome (K91.2)
  • ventilator associated pneumonia (J95.851)

How long has T86.810 existed?

T86.810 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.
