ALL MEDICAL CODES IN CATEGORY Certain disorders involving the immune mechanism

2025 ICD-10-CM code D81.31

Severe combined immunodeficiency due to adenosine deaminase deficiency.

2025 ICD-10-CM code D89.813

Graft-versus-host disease, unspecified. This occurs when immune cells from a donor's transplanted tissue attack the recipient's healthy tissues.

2025 ICD-10-CM code D83.9

Common variable immunodeficiency (CVID) is a condition where the body's immune system is unable to effectively fight infections due to low levels of immunoglobulins (antibodies). This code specifies an unspecified type of CVID.

2025 ICD-10-CM code D89.43

Secondary mast cell activation.This condition involves the improper activation of mast cells, leading to an excessive allergic response due to an underlying disease.

2025 ICD-10-CM code D84.822

Immunodeficiency due to external causes.

2025 ICD-10-CM code D81.819

Unspecified biotin-dependent carboxylase (BDC) deficiency, also known as multiple carboxylase deficiency.It is a rare inherited disorder characterized by abnormal carboxylase enzyme function due to biotin deficiency.

2025 ICD-10-CM code D81.2

Severe combined immunodeficiency (SCID) with low or normal B-cell numbers is a type of SCID where T cells are absent, and B and/or NK cell counts can be low, none, high, or normal.B cells, even if present, are non-functional due to the absence of T cells.

2025 ICD-10-CM code D80.9

Unspecified immunodeficiency with predominantly antibody defects (PADs).

2025 ICD-10-CM code D81.810

Biotinidase deficiency is an inherited disorder that affects the body's ability to recycle biotin.

2025 ICD-10-CM code D89.40

Mast cell activation, unspecified. This condition involves inappropriate activation of mast cells, leading to an excessive release of chemical mediators like histamine.

2025 ICD-10-CM code D86.84

Sarcoid pyelonephritis. Tubulo-interstitial nephritis in sarcoidosis.

2025 ICD-10-CM code D86.81

Sarcoid meningitis is the inflammation of the membranes surrounding the brain and spinal cord, caused by sarcoidosis.

2025 ICD-10-CM code D84.821

Immunodeficiency due to drugs. This condition is characterized by a weakened immune system resulting from medication use.

2025 ICD-10-CM code D83.8

Other common variable immunodeficiencies (CVIDs) involve the body's immune system being unable to fight infection due to B lymphocytes or plasma cells not producing antibodies. This leads to low immunoglobulin levels and frequent bacterial infections.

2025 ICD-10-CM code D81.81

Biotin-dependent carboxylase deficiency, also known as multiple carboxylase deficiency.

2025 ICD-10-CM code D86.87

Sarcoid myositis.A manifestation of sarcoidosis causing muscle inflammation characterized by non-necrotizing granulomas.

2025 ICD-10-CM code D81.4

Nezelof syndrome is a rare, inherited immunodeficiency disorder characterized by underdevelopment of the thymus gland, leading to T-cell deficiency but normal immunoglobulin levels.

2025 ICD-10-CM code D82.9

Unspecified immunodeficiency associated with a major defect. This condition involves a compromised immune system with an associated defect, the specific type of which is not documented.

2025 ICD-10-CM code D89

Other disorders involving the immune mechanism, not elsewhere classified.

2025 ICD-10-CM code D89.839

Cytokine release syndrome (CRS), grade unspecified.This code describes a systemic inflammatory response characterized by the excessive release of inflammatory mediators called cytokines.

2025 ICD-10-CM code D86.8

Sarcoidosis of other sites. This code encompasses sarcoidosis affecting areas not specifically classified elsewhere.

2025 ICD-10-CM code D86.86

Sarcoid arthropathy. Polyarthritis in sarcoidosis.

2025 ICD-10-CM code D84.81

Immunodeficiency due to conditions classified elsewhere. Code first the underlying condition, such as chromosomal abnormalities, diabetes mellitus, or malignant neoplasms.

2025 ICD-10-CM code D81.39

Other adenosine deaminase deficiency. This condition is a type of combined immunodeficiency, distinct from severe combined immunodeficiency (SCID) caused by ADA deficiency.

2025 ICD-10-CM code D81.30

Adenosine deaminase deficiency, unspecified. This condition involves a deficiency in the enzyme adenosine deaminase.

2025 ICD-10-CM code D81.9

Combined immunodeficiency, unspecified. This condition involves an inherited disorder leading to recurrent, severe, and/or opportunistic infections, inflammatory diseases, autoimmune conditions, excessive lymphocytes, and increased malignancy risk.The specific type of CID is not specified.

2025 ICD-10-CM code D81.89

This code represents other combined immunodeficiencies, a group of inherited disorders causing recurrent infections and other immune-related problems, not classified elsewhere.

2025 ICD-10-CM code D81.8

This code represents other combined immunodeficiencies, a group of rare, inherited disorders that impair the immune system, leading to increased susceptibility to infections.

2025 ICD-10-CM code D80.8

Other immunodeficiencies with predominantly antibody defects. This encompasses various conditions not specifically classified elsewhere, characterized by impaired antibody production or function, leading to increased susceptibility to infections.

2025 ICD-10-CM code D89.49
