About N14.2

N14.2 is the ICD-10-CM diagnosis code for nephropathy induced by unspecified drug, medicament or biological substance. It belongs to category N14 (Drug- and heavy-metal-induced tubulo-interstitial and tubular conditions), block N10-N16 (renal tubulo-interstitial diseases) and chapter 14 (diseases of the genitourinary system). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within N14, choose N14.2 (Nephropathy induced by unspecified drug, medicament or biological substance) only when documentation doesn't support a more specific option: analgesic nephropathy (N14.0), nephropathy induced by other drugs, medicaments and biological substances (N14.1), nephropathy induced by heavy metals (N14.3) and toxic nephropathy, not elsewhere classified (N14.4).

Code first: poisoning due to drug or toxin, if applicable (T36-T65 with fifth or sixth character 1-4).

Use an additional code for adverse effect, if applicable, to identify drug (T36-T50 with fifth or sixth character 5).

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 698 (Other Kidney and Urinary Tract Diagnoses with MCC, relative weight 1.6398), DRG 699 (Other Kidney and Urinary Tract Diagnoses with CC, relative weight 1.0003) and DRG 700 (Other Kidney and Urinary Tract Diagnoses without CC/MCC, relative weight 0.6741), 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 has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 583.89 (nephritis and nephropathy, not specified as acute or chronic, with other specified pathological lesion in kidney).
