About R82.992

R82.992 is the ICD-10-CM diagnosis code for hyperoxaluria. It belongs to category R82 (other and unspecified abnormal findings in urine), block R80-R82 (abnormal findings on examination of urine, without diagnosis) and chapter 18 (symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within R82.99 (other abnormal findings in urine), R82.992 is specifically for hyperoxaluria. Related codes cover Hypocitraturia (R82.991), Hyperuricosuria (R82.993), Hypercalciuria (R82.994) and other abnormal findings in urine (R82.998).

Don't report R82.992 together with the conditions in its Excludes1 note: primary hyperoxaluria (E72.53-) and secondary hyperoxaluria (E72.54-).

Use an additional code to identify any retained foreign body, if applicable (Z18.-).

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

In MS-DRG v44.0, it is part of the grouping logic for DRG 695 (Kidney and Urinary Tract Signs and Symptoms with MCC, relative weight 1.1139) and DRG 696 (Kidney and Urinary Tract Signs and Symptoms without MCC, relative weight 0.6679), in MDC 11 (Diseases and Disorders of the Kidney and Urinary Tract), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

It was added in FY2019, effective October 1, 2018.
