Guidelines:
CKD:
When the patient has anemia due to chronic kidney
disease (CKD) you must report a code from N18 (CKD) in addition to D63.1
(Anemia in chronic kidney disease). Codes from N18- indicate the stage of the
illness
Example:
Patient presented for treatment of stage 3 CKD. The
provider also addresses the CKD caused anemia during the encounter. You should
report N18.3 – CKD stage 3 – moderate followed by D63.1 for the anemia.
Neoplastic Disease:
In cases where the patient has anemia due to a
neoplasm, you should report the proper neoplasm code alongside D63.0 (Anemia in
neoplastic disease) However if a patient has anemia caused by his chemotherapy,
immunotherapy, or radiotherapy and he presents for the treatment of the anemia
only your first listed code should be an adverse effect code. Then report the anemia and neoplasm codes.
Drug Induced Anemias:
Autoimmune hemolytic anemia is caused by auto antibody
induced hemolysis. It is usually idiopathic but can be associated with
infection, lymphoproliferative disorders, autoimmune diseases and some drugs.
Category D59 contains
codes used to report the different types of hemolytic anemias. D59.0 (Drug
induced autoimmune hemolytic anemia) and D59.1 (Other autoimmune hemolytic
anemia) codes require an additional code to identify the drug. Select a code
from T36-T50 with 5th or 6th character 5.
Focus on the sequencing of the principal diagnosis
(PDX) when patients present with anemia (Chapter 3 in ICD-10). Anemia is the
most common disorder of the blood and it affects about a quarter of the
population in the world.
Here are a few examples:
· Patient
is admitted with anemia due to chronic kidney disease (CKD) or end stage renal disease
(ESRD). CKD/ESRD would be the appropriate PDX selection even when
treatment is directed towards the anemia only. Per the instructional
notes in ICD-10-CM, code first the underlying cause. The manifestation
code would not be appropriate as the PDX.
Patient
is admitted with anemia due to underlying malignancy. The site of the
malignancy would be the appropriate PDX selection even when treatment is
directed towards the anemia only. Per the instructional notes in
ICD-10-CM, code first the neoplasm. When reading the documentation in the
record coders should look for documentation to see if this is anemia of the
malignancy or if this is due to the treatment of the malignancy (surgical blood
loss anemia or drug induced anemia). If not due to the malignancy but due to
the treatment of the malignancy then anemia may be appropriate as the PDX.
·
Patient
is admitted with anemia and malignancy. The physician documents that the
anemia is due to the anti-neoplastic drugs that the patient has been
taking. In this case, the anemia due to antineoplastic chemotherapy would
be sequenced as the PDX and not the malignancy (if the treatment is only
directed at the anemia).
· Patient
is admitted with anemia due to rheumatoid arthritis and lupus. Treatment
is directed at correcting the anemia. The underlying chronic condition of
rheumatoid or lupus would be the appropriate PDX selection. Per the
instructional notes in ICD-10-CM, code first the underlying chronic condition.
Below are a few
definitions of anemia and the types associated with chronic
diseases/malignancy. Please keep in mind, this is a very small selection
of types of anemia (there are over 400 types but can be divided into three
groups…anemia caused by blood loss, anemia caused by decreased or faulty red blood
cell production, and anemia caused by destruction of red blood cells).
Anemia—decrease in the amount of RBCs or hemoglobin
in the blood
Anemia of Chronic Disease (or of chronic
inflammation)—This type of anemia is associated with many underlying chronic
disorders including cancer, infections, autoimmune disease, inflammatory
diseases or kidney disease being the most common culprits.
Anemia due to Chemotherapy—very common side effect
of use of chemotherapy drugs treating malignancy. Chemotherapy reduces
the bone marrow’s ability to make red blood cells.
Sickle–cell trait (SCT) refers to a type of sickle–cell disorder (SCD) that leads to formation of hard, sticky, and sickle–shaped (C–shaped) red blood cells (RBCs) and decreased number of red cells compared to normal, causing anemia. A patient with SCT receives one sickle cell gene (S) from one parent and one normal gene (A) from another parent.
