T86 is a non-billable ICD-10-CM category code for complications of transplanted organs and tissue, so it cannot be submitted on claims. Use a more specific code from this category instead, such as T86.00, T86.01, T86.02, and T86.03.

Coding GuidelinesGuidance

The appropriate 7th character is to be added to each code from block Complications of transplanted organs and tissue (T86). Use the following options for the applicable episode of care:

  • A - initial encounter
  • D - subsequent encounter
  • S - sequela

Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to T86: its own notes plus those printed at block T80-T88 and Chapter 19. A note printed at a category, block or chapter applies to every code under it.

Excludes2

Not included here: the excluded condition is not part of this code, but a patient may have both, so both codes may be reported.

From Block T80-T88 Complications of surgical and medical care, not elsewhere classified applies to 1,683 codes

From Chapter 19 (S00-T88) Injury, poisoning and certain other consequences of external causes applies to 41,187 codes

Use Additional Code

Add a second code, after this one, to fully describe the condition.

On T86 itself
  • 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)
From Block T80-T88 Complications of surgical and medical care, not elsewhere classified applies to 1,683 codes

From Chapter 19 (S00-T88) Injury, poisoning and certain other consequences of external causes applies to 41,187 codes
  • code to identify any retained foreign body, if applicable (Z18.-)

Notes

General instructions on how these codes are used.

From Chapter 19 (S00-T88) Injury, poisoning and certain other consequences of external causes applies to 41,187 codes
  • Use secondary code(s) from Chapter 20, External causes of morbidity, to indicate cause of injury. Codes within the T section that include the external cause do not require an additional external cause code
  • The chapter uses the S-section for coding different types of injuries related to single body regions and the T-section to cover injuries to unspecified body regions as well as poisoning and certain other consequences of external causes.

Questions About T86Overview

What is the ICD-10 code for complications of transplanted organs and tissue?

T86 is the ICD-10-CM category for complications of transplanted organs and tissue, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is T86 (Complications of transplanted organs and tissue) a billable code?

No. This is a category header that groups the codes for complications of transplanted organs and tissue, and headers cannot be submitted on claims. Claims for complications of transplanted organs and tissue need a more specific code from this category, such as T86.00, T86.01, and T86.02.

Does T86 need an additional code?

When the condition applies, yes. The Use Additional Code note reads: 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). The additional code is reported after T86.
