Potential conditions associated with high homocysteine levels include:
Your body uses TMG to convert homocysteines into methionine, helping to reduce the level of homocysteines in your blood. Taking TMG combined with folic acid and vitamin B12 can help lower your homocysteine levels. Make sure to talk to your doctor before taking TMG supplements to lower your homocysteine levels.
Homocysteine is an amino acid produced when proteins are broken down. A high homocysteine level, also called hyperhomocysteinemia, can contribute to arterial damage and blood clots in your blood vessels. High homocysteine levels usually indicate a deficiency in vitamin B-12 or folate.
Homocysteine levels will be covered by Medicare to confirm Vitamin B12 or folate deficiency. known vascular disease or risk thereof (based upon abnormal lipid metabolism, high blood pressure (BP) or diabetes mellitus (DM)) for the purpose of risk stratification.
A homocysteine test measures the amount of homocysteine in your blood. Homocysteine is a type of amino acid, a chemical your body uses to make proteins. Normally, vitamin B12, vitamin B6, and folic acid break down homocysteine and change it into other substances your body needs.
Vitamin B12 deficiency anemia due to intrinsic factor deficiency. D51. 0 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2022 edition of ICD-10-CM D51.
Homocysteine is an intermediary amino acid formed by the conversion of methionine to cysteine (figure 1). Homocystinuria is a rare autosomal recessive disorder characterized by severe elevations in plasma and urine homocysteine concentrations.

On the basis of the same convention, we suggest the abbreviation “HcyH” for the free thiol, homocysteine itself.
There is agreement within the literature that serum vitamin B12 testing should be used to diagnose vitamin B12 deficiency in symptomatic and high-risk populations. One of the leading causes of vitamin B12 deficiency is pernicious anemia, an autoimmune disease that results in the failure to produce intrinsic factor.
ICD-10 code Z13. 220 for Encounter for screening for lipoid disorders is a medical classification as listed by WHO under the range - Factors influencing health status and contact with health services .
2. For 82306: If more than one LCD-listed condition contributes to Vitamin D deficiency in a given patient and/or is improved by Vitamin D administration, coders should use: ICD-10 E55. 9 UNSPECIFIED VITAMIN D DEFICIENCY. This code should not be used for any other indication.
Homocystinuria (HCU) is a rare but potentially serious inherited condition. It means the body can't process the amino acid methionine. This causes a harmful build-up of substances in the blood and urine.
Clear signs that may lead a doctor to test for homocystinuria include a child being extremely thin and too tall for their age or not growing as expected. Additionally, the doctor will look for signs of chest deformity, spinal curvature, and dislocated eye lenses.
Vitamin B12 deficiency, therefore, can lead to increased levels of serum methylmalonic acid. In the second reaction, homocysteine is converted to methionine by using vitamin B12 and folic acid as cofactors. In this reaction, a deficiency of vitamin B12 or folic acid may lead to increased homocysteine levels.

Excess levels in the blood are purported to increase the risk of stroke, certain types of heart disease or peripheral artery disease (PAD). Homocysteine (Hcy), a sulphur-containing amino acid, is formed from the conversion of methionine into cysteine. It is usually rapidly metabolized via 1 of 2 pathways:
a vitamin B6-dependent trans-sulphuration pathway that converts Hcy to cysteine. Thus, low levels of these vitamins/co-factors are associated with hyper-homocysteinemia, which can be classified as moderate (15 to 30 micromol/L), intermediate (31 to 100 micromol/L), or severe (greater than 100 micromol/L).
Aetna considers homocysteine testing experimental and investigational for all other indications, including the following (not an all inclusive list) because its effectiveness for these indications has not been established: As a biomarker for the development and/or progression of erectile dysfunction.

Homocysteine - An elevated concentration of homocysteine is an independent risk factor for cardiovascular disease. When used in conjunction with methylmalonic acid (MMA), these tests are useful to diagnose and monitor vitamin B12 (cobalamin) and folic acid deficiency and are often useful in evaluating macrocytosis (an elevated MCV, ...
