Your Quick Guide to Understanding the Weird 14 Day Rule (CMS Billing for Lab Tests)

Babe Ruth marveled that he got "paid for playing baseball," since it was so much fun.  I marvel that I get paid for explaining Medicare's lab test "14 day rule" - because it is so bizarre.


For some examples of how unpopular this rule is in policy circles, see here.   More after the break.

In policymaking around 2000-2001, Medicare tried to set uniform national rules for most administrative features of clinical laboratory tests.  (Google the words, Medicare negotiated rulemaking for labs, and see the results; or try this link, here.)   Among other administrative details, Medicare set the date of service for lab tests as the date of specimen collection (rather than, say, the date of test performance or the date of test ordering.)

As often happens, once one rule is set, questions arose.  This specimen was collected on July 1, 2003.  It was stored frozen til February 10, 2004, when a test was ordered on it.  Is the date of service July 1, 2003?  That seems odd.  So a new rule was added, the date of service for such an archived specimen is the date it was pulled from an archive.

CMS wanted to apply the rule to "bundle" hospital outpatient specimens to the hospital where they originated, and so CMS elevated the rule from mere policy to formal rulemaking in 2006.  Some labs protested that 30 days was too long, so CMS made a 14 day exception: if the test is ordered 14 days after a hospital inpatient or outpatient biopsy, then, the date of service is neither the date of specimen collection, nor the date of pull from an archive, but yet another date, the date of test performance.

CMS quickly emphasized that if the date of service rule placed the "date of service" (which is now an administrative fiction, not a real date of a real lab service) on a day when the patient was in a hospital, then only the hospital could bill for it.   So if a hospital draws outpatient blood on clinic patient Mary Jones on July 1, and does three tests itself, and sends one esoteric test to Quest on July 8, only the hospital can bill Medicare for the test.

Wait again - up til January 1, 2014, after which, Medicare "packaged" all clinical chemistry tests to the hospital outpatient office visit or service payment, and nobody could bill for the test anymore.  Unless, through another exception, it was a human genetic test (defined by AMA CPT code series.)  (HIV viral load tests - not a human genetic test.)

And as of January 1, 2015, most pathology tests on hospital outpatient specimens are also bundled.

I've attached a six page PowerPoint deck with my best current efforts to illustrate the rule graphically.  I start with the original 30 day rule, because the 14 day rule is actually only an exception to the previously stated 30 day rule.   PowerPoint deck in the cloud, here.

Pop quiz: Can you name the   s i x  different dates that are required to manage the 14 day rule? (see deck, page 2).

14 Day Rule Extra Credit Question

A patient is hospitalized July 1, with surgical biopsy that day.  60 days later on August 30 he is finally discharged.  

A test is ordered by the attending on August 10 and run on DNA newly extracted from the paraffin block on August 12.  What is the DOS?  Who can bill?   

Answer:  DOS:  The 30 day rule initially locks the DOS as the "date of specimen collection" (July 1).   The 14 day rule does not apply (the new test is not ordered 14 days after discharge.)  The Archive rule states that if a specimen is pulled from an archive after 30 days of date of collection, then, the DOS is the date pulled from an archive.  If the specimen is pulled on August 11 (between the order and the extraction), then that is the DOS, the "date pulled from archive."  

Who can bill?  August 11 is a date that falls during the hospital admission (July 1 - August 30) so it falls under the DRG and no one can bill.
