Other specified renal tubulo-interstitial diseases

This code represents a variety of non-infectious, non-obstructive kidney disorders primarily affecting the renal tubules and interstitial tissue, which do not fit into more specific categories. These conditions involve inflammation, fibrosis, or damage to these structures, leading to impaired kidney function.

Use this code for documented renal tubulo-interstitial diseases that are not explicitly classified elsewhere, such as certain forms of drug-induced nephropathy, heavy metal nephropathy, or other toxic nephropathies. Documentation should clearly specify the tubulo-interstitial involvement and rule out more specific diagnoses like acute pyelonephritis or reflux nephropathy.

• Ensure documentation specifies the "other" nature of the tubulo-interstitial disease, differentiating it from more common forms.
• Avoid using this code if a more specific ICD-10-CM code exists for the documented tubulo-interstitial condition (e.g., drug-induced acute tubulo-interstitial nephritis).
• Always sequence this code after the underlying cause if known and applicable (e.g., specific drug, toxin exposure).
