Since vitamin B 12 is not present in plants, humans have obtained their supply from animal products, from multivitamin supplements in the form of pills, and as additives to food preparations. A wide variety of neuropsychiatric abnormalities is also seen in vitamin B 12 deficiency and appears to be due to an undefined defect involving myelin synthesis. A nutritional condition produced by a deficiency of FOLIC ACID in the diet. Many plant and animal tissues contain folic acid, abundant in green leafy vegetables, yeast, liver, and mushrooms but destroyed by long-term cooking. Alcohol interferes with its intermediate metabolism and absorption. Folic acid deficiency may develop in long-term anticonvulsant therapy or with use of oral contraceptives. This deficiency causes anemia, macrocytic anemia, and megaloblastic anemia. It is indistinguishable from vitamin B 12 deficiency in peripheral blood and bone marrow findings, but the neurologic lesions seen in B 12 deficiency do not occur. 266.2 is a specific code that can be used to specify a diagnosis 266.2 contains 26 index entries View the ICD-9-CM Volume 1 266.* hierarchy Alternate Terminology Deficiency: cyanocobalamin folic acid vitamin B12 266.2 Excludes combined system disease with anemia (281.0-281.1) deficiency anemias (281.0-281.9) subacute degeneration of spinal cord with anemia (281.0-281.1)  Index entries containing 266.2: Acid deficiency folic 266.2 pantothenic 266.2 Avitaminosis (multiple NEC) (see also Deficiency, vitamin) 269.2 B12 266.2 Barasheh, barashek 266.2 Burning feet syndrome 266.2 Chacaleh 266.2 Deficiency, deficient biotin 266.2 choline 266.2 cyanocobalamin (vitamin B12) 266.2 folic acid (vitamin BC) 266.2 anemia 281.2 inositol (B complex) 266.2 pantothenic acid 266.2 vitamin (multiple) NEC 269.2 B (complex) NEC 266.9 specified type NEC 266.2 B12 266.2 BC (folic acid) 266.2 folic acid 266.2 H 266.2 Electric feet (foot) syndrome 266.2 Gopalan's syndrome (burning feet) 266.2 Lightning (effects) (shock) (stroke) (struck by) 994.0 foot 266.2 Melalgia, nutritional 266.2 Painful - see also Pain feet syndrome 266.2 Syndrome - see also Disease burning feet 266.2 electric feet 266.2 Gopalan's (burning feet) 266.2 painful feet 266.2
