Range Overview
The ICD-10 code range N10-N16 pertains to renal tubulo-interstitial diseases. These codes are used to classify kidney diseases that affect the renal tubules and interstitial tissue, which includes conditions such as acute tubulo-interstitial nephritis, chronic tubulo-interstitial nephritis, and renal sclerosis. The codes in this range are essential for accurate medical documentation and billing, and they provide a standardized language for clinicians, researchers, and health insurance companies.
Key Usage Points:
- •Always code to the highest level of specificity.
- •Use additional codes to identify any associated conditions or complications.
- •Codes in this range can be used in any healthcare setting.
- •Chronic conditions require documentation of the patient's long-term care.
- •Acute conditions require documentation of the patient's immediate care.
Coding Guidelines
When to Use:
- ✓When a patient is diagnosed with a renal tubulo-interstitial disease.
- ✓When a patient has a history of renal tubulo-interstitial disease.
- ✓When a patient is receiving treatment for a renal tubulo-interstitial disease.
- ✓When a patient's renal tubulo-interstitial disease affects their medical treatment.
- ✓When a patient's renal tubulo-interstitial disease is a factor in their hospital admission.
When NOT to Use:
- ✗When a patient has a renal disease that is not tubulo-interstitial.
- ✗When a patient has a history of renal disease, but it is not currently active.
- ✗When a patient's renal disease is not a factor in their medical treatment.
- ✗When a patient's renal disease does not affect their hospital admission.
- ✗When a patient's renal disease is not documented in their medical record.
Code Exclusions
Always verify exclusions with the patient's medical record and the official ICD-10 guidelines.
Documentation Requirements
Documentation for codes in the N10-N16 range should include the diagnosis, any associated conditions or complications, and the patient's treatment plan. The documentation should be clear, concise, and based on the patient's medical record.
Clinical Information:
- •Diagnosis of a renal tubulo-interstitial disease.
- •Any associated conditions or complications.
- •Patient's treatment plan.
- •Patient's response to treatment.
- •Patient's prognosis.
Supporting Evidence:
- •Laboratory test results.
- •Imaging studies.
- •Pathology reports.
- •Clinical notes.
Good Documentation Example:
Patient diagnosed with chronic tubulo-interstitial nephritis. Patient has a history of recurrent urinary tract infections. Patient is receiving antibiotic therapy.
Poor Documentation Example:
Patient has kidney disease.
Common Documentation Errors:
- âš Not coding to the highest level of specificity.
- âš Not documenting associated conditions or complications.
- âš Not documenting the patient's treatment plan.
- âš Not documenting the patient's response to treatment.
Range Statistics
Coding Complexity
Coding for renal tubulo-interstitial diseases is moderately complex due to the need to understand the anatomy and physiology of the kidney, differentiate between acute and chronic conditions, identify associated conditions or complications, code to the highest level of specificity, and keep up-to-date with changes to the ICD-10 guidelines.
Key Factors:
- â–¸Understanding the anatomy and physiology of the kidney.
- â–¸Differentiating between acute and chronic conditions.
- â–¸Identifying associated conditions or complications.
- â–¸Coding to the highest level of specificity.
- â–¸Keeping up-to-date with changes to the ICD-10 guidelines.
Specialty Focus
Codes in the N10-N16 range are primarily used by nephrologists, but they can also be used by internists, hospitalists, and other clinicians who treat patients with renal diseases.
Primary Specialties:
Clinical Scenarios:
- • A patient with acute tubulo-interstitial nephritis due to a drug reaction.
- • A patient with chronic tubulo-interstitial nephritis due to recurrent urinary tract infections.
- • A patient with renal sclerosis due to hypertension.
- • A patient with a history of renal tubulo-interstitial disease who is receiving dialysis.
- • A patient with a renal tubulo-interstitial disease who is being evaluated for a kidney transplant.

Frequently Asked Questions
Can I use a code from the N10-N16 range for a patient with a renal disease that is not tubulo-interstitial?
No, the N10-N16 range is specifically for renal tubulo-interstitial diseases. Other renal diseases have their own codes.
