The above is a link to a document which contains the research and reasoning for Medicare's acceptance of INR Home Testing.
Perhaps your doctor will reconsider when she has documentation to show that the government, Medicare, covers in home testing for people with medcanical valves and people with a-fib?
If this does not sway your doctor, you probably might try finding a new doctor, as hard as that may be.

This is a Very Interesting but LONG memo (14 pages) that gets off to a Slow Start citing the reasons skeptics were not in favor of Home Testing.
The Conclusions from multiple studies at multiple sites by different researchers ALL came to the Same Conclusion:
Of the 3 primary test sites,
(1) Physicians Offices, (80% of patients)
(2) Coumadin Clinics, (20% of patients)
(3) Home Testing, (not widely practiced in 2001 when the studies were conducted)
Physicians Offices had the WORST outcomes and greatest variability.
Coumadin Clinics had better results
Home Testing had the BEST results for a number of reasons including more frequent testing (therefore catching changes more quickly which required smaller and fewer dose changes).
The paragraph on Frequency of Testing (page 3) includes an interesting commentary on Anti-Coagulation RISKS vs. INR which (deductively) concludes that the 'safest range' is from 2.0 to 3.0 with a somewhat elevated risk of bleeding from 3.0 to 4.0 and a significantly greater risk of bleeding at 6.0. It also mentions that the risk of STROKE rises RAPIDLY for an INR Below 2.0
I recommend reading the memo for the detailed analysis of the individual studies.
