Lipoprotein deficiencies

This code signifies a group of rare genetic disorders characterized by abnormally low levels of lipoproteins in the blood. These deficiencies can impact the transport of lipids, leading to various systemic manifestations depending on the specific lipoprotein affected.

Use this code for documented cases of primary lipoprotein deficiencies such as abetalipoproteinemia, hypobetalipoproteinemia, or Tangier disease. Supporting documentation should include laboratory findings confirming low lipoprotein levels and a definitive diagnosis from a physician.

• Differentiate between primary (genetic) and secondary lipoprotein deficiencies; this code is for primary forms.
• Ensure the medical record clearly specifies the type of lipoprotein deficiency when possible, though this code is a general category.
• Consider sequencing this code as a primary diagnosis when it is the reason for the encounter, or as a secondary diagnosis if it is a co-morbidity.
