Pernicious Anemia ICD-10-CM Codes

What ICD-10 Codes Are Used for Pernicious Anemia?

Pernicious Anemia, a type of vitamin B12 deficiency anemia, has unique ICD-10-CM codes, which help to identify it in the medical field:

• D51.0 - Vitamin B12 deficiency anemia due to intrinsic factor deficiency: This code specifically points to pernicious anemia, an autoimmune condition impairing the absorption of vitamin B12.
• D51.1 - Vitamin B12 deficiency anemia due to selective vitamin B12 malabsorption with proteinuria: This code is used for Imerslund-Grasbeck syndrome, a rare disorder causing B12 deficiency, which may resemble pernicious anemia.
• D51.9 - Vitamin B12 deficiency anemia, unspecified: This code is for instances when B12 deficiency anemia is diagnosed, but its specific cause hasn't been determined.

Which Pernicious Anemia ICD Codes Are Billable?

The billability of these codes is subjected to specific factors, including the patient's condition details and their insurance provider's policies.

• D51.0 - Yes, this code is billable, covering diagnoses of pernicious anemia.
• D51.1 - Yes, this code is also billable and applicable to conditions akin to pernicious anemia, like Imerslund-Grasbeck syndrome.
• D51.9 - Yes, this code is billable for non-specific diagnoses of B12 deficiency anemia.

Clinical Information

Pernicious anemia is a complex condition stemming from a vitamin B12 deficiency, essential for making red blood cells and maintaining a healthy nervous system.

• This disorder impairs the body's ability to absorb vitamin B12 from food due to a lack of intrinsic factors produced by the stomach lining.
• Symptoms might include fatigue, shortness of breath, rapid heartbeat, cognitive difficulties, unsteady movements, and numbness or tingling in hands and feet.
• It's usually treated with B12 injections or high-dose oral supplements, dietary advice, and, in some cases, proton pump inhibitors to reduce stomach acid levels.

Synonyms Include:

• Vitamin B12 Deficiency Anemia
• Addision's Anemia
• Biermer's Anemia
• Megaloblastic Anemia Type 1
• Anemia - Pernicious
