Code Classification

  • Diseases of the genitourinary system
    (N00–N99)
    • Other diseases of the urinary system
      (N30-N39)
      • Neuromuscular dysfunction of bladder, not elsewhere classified
        (N31)

N31.9 is a billable diagnosis code used to specify a medical diagnosis of neuromuscular dysfunction of bladder, unspecified. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

Unspecified diagnosis codes like N31.9 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.

Approximate Synonyms

The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

  • Abnormal compliance of bladder
  • Acquired obstructive nephropathy due to neurogenic bladder
  • Cauda equina syndrome with neurogenic bladder
  • Functional disorder of bladder
  • Functional disorder of bladder co-occurrent and due to prolapse of female genital organ
  • Functional disorder of bladder neck and sphincter mechanism
  • Late effects of poliomyelitis
  • Neurogenic bladder
  • Neurogenic bladder as late effect of cerebrovascular accident
  • Neurogenic bladder as late effect of poliomyelitis
  • Neurogenic bladder due to quadriplegia
  • Neurogenic bladder due to spina bifida
  • Neurogenic dysfunction of the urinary bladder
  • Paraplegia with neurogenic bladder

Clinical Classification

Clinical Information

  • Cauda Equina Syndrome with Neurogenic Bladder

    a rare neurologic disorder caused by impingement of the nerve roots of the cauda equina secondary to disc herniation, spinal stenosis, vertebral fracture, neoplasm or infection. clinical signs may include bladder or bowel dysfunction, paresthesia and weakness of the lower extremities. the development of neurogenic bladder implies that surgical decompression was either ineffective, delayed or not attempted.
  • Acquired Neurogenic Bladder

    neurogenic bladder, the cause of which is not present at birth.
  • Congenital Neurogenic Bladder

    neurogenic bladder, the cause of which is present at birth.
  • Grade 1 Urinary Retention, CTCAE|CTCAE Grade 1 Urinary retention (including neurogenic bladder)|Grade 1 Urinary retention|Grade 1 Urinary retention (including neurogenic bladder)

    urinary, suprapubic or intermittent catheter placement not indicated; able to void with some residual
  • Grade 2 Urinary Retention, CTCAE|CTCAE Grade 2 Urinary retention (including neurogenic bladder)|Grade 2 Urinary retention|Grade 2 Urinary retention (including neurogenic bladder)

    elective invasive intervention indicated; substantial loss of affected kidney function or mass
  • Grade 4 Urinary Retention, CTCAE|CTCAE Grade 4 Urinary retention (including neurogenic bladder)|Grade 4 Urinary retention|Grade 4 Urinary retention (including neurogenic bladder)

    life-threatening consequences; organ failure; urgent operative intervention indicated

    death
  • Neurogenic Bladder

    malfunctioning urinary bladder due to central nervous system disorders or damage to the peripheral nerves that are involved in the control of urination. causes include spinal cord injuries, neural tube defects, brain tumors, strokes, and peripheral neuropathies (e.g., aids neuropathy and diabetic neuropathy).
  • Non-Neurogenic Neurogenic Bladder|Hinman Syndrome

    bladder sphincter dysfunction in an individual with normal bladder innervation, which may lead to renal impairment.
  • Urinary Retention, CTCAE|Urinary Retention|Urinary Retention (Priority 1)|Urinary retention|Urinary retention (including neurogenic bladder)

    a disorder characterized by accumulation of urine within the bladder because of the inability to urinate.

These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.

Patient Education


Bladder Diseases

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.
