Blood Coagulation Home Testing Devices

Medica Coverage Policy
Policy Name:
Blood Coagulation Home Testing Devices
Current Policy Effective Date: 2/1/2015
Important Information – Please Read Before Using This Policy
These services may or may not be covered by all Medica plans. Please refer to the member’s plan document for
specific coverage information. If there is a difference between this general information and the member’s plan
document, the member’s plan document will be used to determine coverage. With respect to Medicare, Medicaid
and MinnesotaCare members, this policy will apply unless these programs require different coverage. Members
may contact Medica Customer Service at the phone number listed on their member identification card to discuss
their benefits more specifically. Providers with questions about this Medica coverage policy may call the Medica
Provider Service Center toll-free at 1-800-458-5512.
Medica coverage policies are not medical advice. Members should consult with appropriate health care providers to
obtain needed medical advice, care and treatment.
Coverage Policy
Blood coagulation home testing devices are COVERED for patients requiring long-term (i.e., greater than six
months) or lifelong oral anticoagulant therapy, including but not limited to post-heart valve replacement, recurrent
deep vein thrombosis, or chronic atrial fibrillation.
Note: This policy is no longer scheduled for routine review of the scientific literature.
Warfarin (Coumadin®, dicumarol) anticoagulation therapy interferes with the formation of vitamin K-dependent
clotting factors and has a narrow therapeutic range that is easily influenced by such things as changes in diet, drug
interactions, and illness. This necessitates frequent blood coagulation monitoring. The most frequently performed
test for warfarin monitoring is the prothrombin time (PT). In the office or clinic, PT is measured by adding
thromboplastin and calcium ions to the patient’s plasma following a venous blood collection. Home testing monitors
PT using capillary blood most often collected from a fingerstick. In both cases, PT is reported as an International
Normalized Ratio (INR), which standardizes clotting time by relating it to an International Sensitivity Index (ISI)
that quantifies differences in thromboplastin sensitivities. This allows PT to be reported as a ratio that is
reproducible irrespective of testing location or instrumentation.
Prior to self-monitoring, therapeutic range is established by coagulation testing in a clinical setting. Following selftesting, therapeutic range results are called to the health care provider for regulation of anticoagulant dosage. In
some cases, dosage adjustment may be self-managed. The goal of therapy is consistent maintenance of the patient’s
therapeutic range in order to diminish the risk of internal bleeding or internal clotting.
Anticoagulation home testing is proposed as an alternate to testing at the physician’s office or a coagulation clinic.
Home systems are only available as a prescription issued under a physician’s supervision. Assuming patient
compliance and understanding, blood coagulation home testing is purported to alleviate some of the problems
associated with standard long-term anticoagulation therapy, such as use for patients with poor venous access, with a
life-long anticoagulation need, at an increased risk for hemorrhage or thromboembolism, or who are unable to
access testing facilities. In addition to instruction in the accurate use of the instrument and supplies, a key
component of self-management is a structured patient anticoagulation therapy education program.

FDA Approval
Multiple coagulation systems have received FDA approval for home self-monitoring of prothrombin
time/International Normalized Ratio (PT/INR) by patients receiving warfarin therapy. Examples include, but are not
limited to:
1. CoaguChek® System and CoaguChek® S System
2. ProTime® Microcoagulation System
3. AvoSure™ PT-Pro, AvoSure™ PT-Pro+, AvoSure™ PT
4. Avoset PT-Pro™
5. INRatio® Monitor
Prior Authorization
Prior authorization is not required.
Coding Considerations
Use the current applicable CPT/HCPCS code(s). The following codes are included below for informational purposes
only, and are subject to change without notice. Inclusion or exclusion of a code does not constitute or imply member
coverage or provider reimbursement.
CPT Codes:
• G0248 - Demonstration, prior to initial use, of home INR monitoring for patient with either mechanical heart
valve(s), chronic atrial fibrillation, or venous thromboembolism who meets Medicare coverage criteria, under
the direction of a physician; includes: face-to-face demonstration of use and care of the INR monitor, obtaining
at least one blood sample, provision of instructions for reporting home INR test results, and documentation of
patient ability to perform testing prior to its use
• G0249 - Provision of test materials and equipment for home INR monitoring to 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; not occurring more
frequently than once a week
• G0250 - Physician review, interpretation and patient management of home INR testing for a patient with either
mechanical heart valve(s), chronic atrial fibrillation, or venous thromboembolism who meets Medicare
coverage criteria; includes face-to-face verification by the physician that the patient uses the device in the
context of the management of the anticoagulation therapy following initiation of the home INR monitoring; not
occurring more frequently than once a week.
• E1399 - miscellaneous medical device
