Valid for Submission
D66 is a billable diagnosis code used to specify a medical diagnosis of hereditary factor viii deficiency. The code D66 is valid during the fiscal year 2022 from October 01, 2021 through September 30, 2022 for the submission of HIPAA-covered transactions.
The ICD-10-CM code D66 might also be used to specify conditions or terms like combined deficiency of factor v and factor viii, factor v deficiency, factor viii deficiency, hemophilia, hereditary combined coagulation factor deficiency , hereditary factor viii deficiency disease, etc.
Tabular List of Diseases and Injuries
The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code D66:
Inclusion TermsInclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
- Classical hemophilia
- Deficiency factor VIII (with functional defect)
- Hemophilia NOS
- Hemophilia A
Type 1 ExcludesType 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
- factor VIII deficiency with vascular defect D68.0
Index to Diseases and Injuries
The Index to Diseases and Injuries is an alphabetical listing of medical terms, with each term mapped to one or more ICD-10 code(s). The following references for the code D66 are found in the index:
- - Arthritis, arthritic (acute) (chronic) (nonpyogenic) (subacute) - M19.90
- - Arthropathy - See Also: Arthritis; - M12.9
- - Deficiency, deficient
- - anti-hemophilic
- - factor - See Also: Deficiency, coagulation;
- - Subhemophilia - D66
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Combined deficiency of factor V and factor VIII
- Factor V deficiency
- Factor VIII deficiency
- Hereditary combined coagulation factor deficiency
- Hereditary factor VIII deficiency disease
- Hereditary factor VIII deficiency disease with inhibitor
- Hereditary factor VIII deficiency disease without inhibitor
- Lamellar ichthyosis
- Mild hereditary factor VIII deficiency disease
- Mild hereditary factor VIII deficiency disease with inhibitor
- Mild hereditary factor VIII deficiency disease without inhibitor
- Moderate hereditary factor VIII deficiency disease
- Moderate hereditary factor VIII deficiency disease with inhibitor
- Moderate hereditary factor VIII deficiency disease without inhibitor

Information for Patients
Hemophilia is a rare disorder in which the blood does not clot normally. It is usually inherited. Hemophilia usually occurs in males.
If you have hemophilia, you have little or no clotting factor. Clotting factor is a protein needed for normal blood clotting. Without it, you may bleed for a long time after an injury or accident. You also may bleed into your knees, ankles, and elbows. Bleeding in the joints causes pain and, if not treated, can lead to arthritis. Bleeding in the brain, a very serious complication of hemophilia, requires emergency treatment.
The main symptoms of hemophilia are excessive bleeding and easy bruising. Blood tests can tell if you have it. The main treatment is injecting the missing clotting factor into the bloodstream. You may need it on a regular basis, or just when bleeding occurs.

Hemophilia is a bleeding disorder that slows the blood clotting process. People with this condition experience prolonged bleeding or oozing following an injury, surgery, or having a tooth pulled. In severe cases of hemophilia, continuous bleeding occurs after minor trauma or even in the absence of injury (spontaneous bleeding). Serious complications can result from bleeding into the joints, muscles, brain, or other internal organs. Milder forms of hemophilia do not necessarily involve spontaneous bleeding, and the condition may not become apparent until abnormal bleeding occurs following surgery or a serious injury.
The major types of this condition are hemophilia A (also known as classic hemophilia or factor VIII deficiency) and hemophilia B (also known as Christmas disease or factor IX deficiency). Although the two types have very similar signs and symptoms, they are caused by mutations in different genes. People with an unusual form of hemophilia B, known as hemophilia B Leyden, experience episodes of excessive bleeding in childhood but have few bleeding problems after puberty.
