Other reasons you may be given a PT test are to:
Procedures/Professional Services (Temporary Codes) G0249 is a valid 2020 HCPCS code for Provision of test materials and equipment for home inr monitoring of patient with either mechanical heart valve(s), chronic atrial fibrillation, or venous thromboembolism who meets medicare coverage criteria; includes: provision of materials for use in the home and reporting of test results to physician ...
The new codes are for describing the infusion of tixagevimab and cilgavimab monoclonal antibody (code XW023X7), and the infusion of other new technology monoclonal antibody (code XW023Y7).
NCD - Partial ThromboplastinTime (PTT) (190.16)
1: Abnormal coagulation profile.
2. 'Subtherapeutic INR levels' means that the patient is underwarfarinised, therefore as per ACS 0303 the correct code to assign is D68. 8 Other specified coagulation defects. 3.
Raised INR can be coded with the ICD-10 code R79. 8 Other specified abnormal findings of blood chemistry.
R79. 1 - Abnormal coagulation profile | ICD-10-CM.
020321: Prothrombin Time (PT) and Partial Thromboplastin Time (PTT) | Labcorp.
Patient has an INR test at a lab in the office or at the point of care and follows up with a visit to discuss results. Report CPT codes 85610 (prothrombin time) and 93793. Patient presents for an office visit during which the physician also discusses INR monitoring.
Most often, the prothrombin time is monitored if you are taking the blood-thinning medication warfarin. In this situation, the prothrombin time is expressed as an international normalized ratio (INR).
ICD-10 code Z79. 01 for Long term (current) use of anticoagulants is a medical classification as listed by WHO under the range - Factors influencing health status and contact with health services .
A PTT may be useful in evaluating patients who have a history of a condition known to be associated with the risk of hemorrhage or thrombosis that is related to the intrinsic coagulation pathway. Such abnormalities may be genetic or acquired. For example: dysfibrinogenemia; afibrinogenemia (complete); acute or chronic liver dysfunction or failure, including Wilson's disease; hemophilia; liver disease and failure; infectious processes; bleeding disorders; disseminated intravascular coagulation; lupus erythematosus or other conditions associated with circulating inhibitors, e.g., Factor VIII Inhibitor, lupus-like anticoagulant, etc.; sepsis; von Willebrand's disease; arterial and venous thrombosis, including the evaluation of hypercoagulable states; clinical conditions associated with nephrosis or renal failure; other acquired and congenital coagulopathies as well as thrombotic states.
A PTT may be used to assess patients with signs or symptoms of hemorrhage or thrombosis. For example: abnormal bleeding, hemorrhage or hematoma petechiae or other signs of thrombocytopenia that could be due to disseminated intravascular coagulation; swollen extremity with or without prior trauma.
The PTT is most commonly used to quantitate the effect of therapeutic unfractionated heparin and to regulate its dosing. Except during transitions between heparin and warfarin therapy, in general both the PTT and PT are not necessary together to assess the effect of anticoagulation therapy. PT and PTT must be justified separately.
Testing prior to any medical intervention associated with a risk of bleeding and thrombosis (other than thrombolytic therapy) will generally be considered medically necessary only where there are signs or symptoms of a bleeding or thrombotic abnormality or a personal history of bleeding, thrombosis or a condition associated with a coagulopathy. Hospital/clinic-specific policies, protocols, etc., in and of themselves, cannot alone justify coverage.
The PTT is not useful in monitoring the effects of warfarin on a patient's coagulation routinely. However, a PTT may be ordered on a patient being treated with warfarin as heparin therapy is being discontinued. A PTT may also be indicated when the PT is markedly prolonged due to warfarin toxicity.

encounter for examination for suspected conditions, proven not to exist (Z03.-)
Note: Z codes represent reasons for encounters. A corresponding procedure code must accompany a Z code if a procedure is performed. Categories Z00-Z99 are provided for occasions when circumstances other than a disease, injury or external cause classifiable to categories A00-Y99 are recorded as 'diagnoses' or 'problems'. This can arise in two main ways:
As far as I remmember v72.84 will cover PT/PTT.
You cannot use a dx code the patient does not have so you will need to evaluate the value of theis test for the physician, if the patient's condition they are having the surgery for justifies performing the test then use that dx code otherwise either do not order the test or let the patient know up front that it is not covered and have them sign an ABN and then bill the patient, or do the test and write the charge off when it returns as non paid due to LCD.
