Kidney Stones
A kidney stone is a solid piece of material that forms in the kidney from substances in the urine. It may be as small as a grain of sand or as large as a pearl. Most kidney stones pass out of the body without help from a doctor. But sometimes a stone will not go away.

Questions About Z87.442Overview
Is Z87.442 (Personal history of diseases of urinary system) a billable code?

Can Z87.442 be a principal diagnosis?
No. The Medicare Code Editor rejects this code as a principal diagnosis because personal history of urinary calculi describes a circumstance that influences health status rather than a current illness. Report it as a secondary diagnosis.
Is Z87.442 exempt from POA reporting?
Yes. CMS lists this code among those exempt from present on admission reporting, so hospitals do not assign a POA indicator for personal history of urinary calculi on inpatient claims.

Under the General Equivalence Mappings, personal history of urinary calculi converts to ICD-9-CM V13.01 (prsnl hst urnr dsrd calc). The mapping is a direct match.
