This diagnosis is a part of ICD10 collection.

Use this code if the thrombocytopenia is not related to the other options or the cause is unknown.
Regarding a "threshold" to identify low platelets:
- The usual lower reference value (which represent the value for which 97.5% of NORMAL people are above, is 150,000. This means then that 2.5% of normal people DO have <150,000 platelets. This makes it tricky to give a single reference value below which we'll call them thrombocyotpenic.
- Further complicating the situation, normals have relatively little fluctuations in their counts. Thus, a person whose usual count is 300,000, will actually be "relatively thrombocytopenic" if their count falls to 180,000.
THUS, in light of this, we will define, for our use, thrombocyotpenia as a lab finding (not necessarily as a disease or as a cause of bleeding) if either of the following is true:
- Count <120,000
- Fall by >100,000 from baseline

-{{DA| Normal platelet count range is 140-440; what value is considered thrombocytopenia, whenever platelet count is less than 140? Then a patient with a platelet count of 139 could be coded as having thrombocytopenia.
+*Regarding a "threshold" to identify low platelets:
-Should there be a value guideline for collectors to promote consistent data collection? If so, what value should be used? [[User:Ppiche|Pamela Piche]]}}
