N20.9 is a billable diagnosis code used to specify a medical diagnosis of urinary calculus, unspecified. The code N20.9 is valid during the fiscal year 2021 from October 01, 2020 through September 30, 2021 for the submission of HIPAA-covered transactions.
The ICD-10-CM code N20.9 might also be used to specify conditions or terms like calcium oxalate urolithiasis, calculous pyelonephritis, calculus of upper urinary tract, indinavir urolithiasis, long-term disorder of dialysis , magnesium ammonium phosphate urolithiasis, etc.
Unspecified diagnosis codes like N20.9 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Information for Patients
The bladder is a hollow organ in your lower abdomen that stores urine. Many conditions can affect your bladder. Some common ones are
- Cystitis - inflammation of the bladder, often from an infection
- Urinary incontinence - loss of bladder control
- Overactive bladder - a condition in which the bladder squeezes urine out at the wrong time
- Interstitial cystitis - a chronic problem that causes bladder pain and frequent, urgent urination
- Bladder cancer
Doctors diagnose bladder diseases using different tests. These include urine tests, x-rays, and an examination of the bladder wall with a scope called a cystoscope. Treatment depends on the cause of the problem. It may include medicines and, in severe cases, surgery.
