Clinical Background. Prothrombin, or factor II, is the precursor of thrombin; as such, it plays a key role in the balance between procoagulation and anticoagulation. A prothrombin genetic variant known as 20210G A is associated with elevated levels of prothrombin and with thrombophilia.
The CPT codebook should be updated every 3-5 years. In a concise statement, ICD-9 is the code used to describe the condition or disease being treated, also known as the diagnosis. CPT is the code used to describe the treatment and diagnostic services provided for that diagnosis.
NCCI Procedure-to-Procedure (PTP) edits have a Column 1 and Column 2 HCPCS/CPT code. If the two codes of an edit pair are reported for the same patient on the same date of service, the Column 1 code is eligible for payment but the Column 2 code is denied unless an appropriate NCCI-associated modifier is allowed and reported.
