Renal tubulo-interstitial disease, unspecified
ICD-10 N15.9 is a billable code used to indicate a diagnosis of renal tubulo-interstitial disease, unspecified.
Renal tubulo-interstitial disease encompasses a group of disorders affecting the renal tubules and interstitium, which can lead to impaired kidney function. This condition can arise from various etiologies, including pyelonephritis, interstitial nephritis, and drug-induced nephropathy. Pyelonephritis, an infection of the kidney, can cause inflammation and damage to the renal interstitium. Interstitial nephritis, which may be acute or chronic, often results from allergic reactions to medications, infections, or autoimmune diseases. Hydronephrosis, characterized by the swelling of a kidney due to a build-up of urine, can also contribute to tubulo-interstitial disease if left untreated. Drug-induced nephropathy is a significant concern, particularly with the use of nonsteroidal anti-inflammatory drugs (NSAIDs), certain antibiotics, and chemotherapeutic agents. Urinary tract infections (UTIs) can exacerbate these conditions, leading to further complications. Management often involves the use of antibiotics to treat infections, alongside addressing the underlying cause of the tubulo-interstitial disease. The unspecified nature of this code indicates that the specific type of renal tubulo-interstitial disease has not been clearly defined, necessitating thorough clinical documentation to guide treatment and coding.
Detailed patient history, lab results, imaging studies, and treatment plans.
Patients presenting with renal failure, unexplained electrolyte imbalances, or recurrent UTIs.
Ensure clear documentation of the etiology and any associated conditions to support the diagnosis.
Surgical notes, imaging results, and post-operative follow-up details.
Patients with hydronephrosis or recurrent urinary tract infections requiring surgical intervention.
Document any surgical procedures performed and their relation to renal function.
Used to evaluate kidney size and structure in patients with suspected renal disease.
Document indications for the ultrasound and findings.
Nephrologists may order this for assessing renal function.
N15.9 is used for unspecified renal tubulo-interstitial disease, while N15.1 specifically refers to acute tubulo-interstitial nephritis, which requires more detailed documentation of the acute condition.
