  • Injury, poisoning and certain other consequences of external causes
    (S00–T88)
    • Complications of surgical and medical care, not elsewhere classified
      (T80-T88)
      • Complications of transplanted organs and tissue
        (T86)

T86.0 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of complications of bone marrow transplant. The code is not specific and is NOT valid for the year 2024 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

Specific Coding Applicable to Complications of bone marrow transplant

Non-specific codes like T86.0 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10-CM codes with a higher level of specificity when coding for complications of bone marrow transplant:

  • Use T86.00 for Unspecified complication of bone marrow transplant - BILLABLE CODE

  • Use T86.01 for Bone marrow transplant rejection - BILLABLE CODE

  • Use T86.02 for Bone marrow transplant failure - BILLABLE CODE

  • Use T86.03 for Bone marrow transplant infection - BILLABLE CODE

  • Use T86.09 for Other complications of bone marrow transplant - BILLABLE CODE

Coding Guidelines

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 aplicable episode of care:

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

Patient Education


Bone Marrow Transplantation

Bone marrow is the spongy tissue inside some of your bones, such as your hip and thigh bones. It contains immature cells, called stem cells. The stem cells can develop into red blood cells, which carry oxygen throughout the body, white blood cells, which fight infections, and platelets, which help the blood to clot.

A bone marrow transplant is a procedure that replaces a person's faulty bone marrow stem cells. Doctors use these transplants to treat people with certain diseases, such as:

  • Leukemia
  • Severe blood diseases such as thalassemias, aplastic anemia, and sickle cell anemia
  • Multiple myeloma
  • Certain immune deficiency diseases

Before you have a transplant, you need to get high doses of chemotherapy and possibly radiation. This destroys the faulty stem cells in your bone marrow. It also suppresses your body's immune system so that it won't attack the new stem cells after the transplant.

In some cases, you can donate your own bone marrow stem cells in advance. The cells are saved and then used later on. Or you can get cells from a donor. The donor might be a family member or unrelated person.

Bone marrow transplantation has serious risks. Some complications can be life-threatening. But for some people, it is the best hope for a cure or a longer life.
