Neoplasm of uncertain behavior of meninges, unspecified

Version 2020 Billable Code Neoplasm Uncertain Behavior

Valid for Submission

D42.9 is a billable code used to specify a medical diagnosis of neoplasm of uncertain behavior of meninges, unspecified. The code is valid for the year 2020 for the submission of HIPAA-covered transactions. The ICD-10-CM code D42.9 might also be used to specify conditions or terms like hemangiopericytoma of meninges or neoplasm of uncertain behavior of meninges.

The following anatomical sites found in the Table of Neoplasms apply to this code given the correct histological behavior: arachnoid or dura (cranial) (mater) or meninges or pia mater or subdural .

Table of Neoplasms

The code D42.9 is included in the table of neoplasms by anatomical site. For each site there are six possible code numbers according to whether the neoplasm in question is malignant, benign, in situ, of uncertain behavior, or of unspecified nature. The description of the neoplasm will often indicate which of the six columns is appropriate.

Where such descriptors are not present, the remainder of the Index should be consulted where guidance is given to the appropriate column for each morphological (histological) variety listed. However, the guidance in the Index can be overridden if one of the descriptors mentioned above is present.

Information for Patients


Spinal Cord Diseases

Your spinal cord is a bundle of nerves that runs down the middle of your back. It carries signals back and forth between your body and your brain. It is protected by your vertebrae, which are the bone disks that make up your spine. If you have an accident that damages the vertebrae or other parts of the spine, this can also injure the spinal cord. Other spinal cord problems include

  • Tumors
  • Infections such as meningitis and polio
  • Inflammatory diseases
  • Autoimmune diseases
  • Degenerative diseases such as amyotrophic lateral sclerosis and spinal muscular atrophy

Symptoms vary but might include pain, numbness, loss of sensation and muscle weakness. These symptoms can occur around the spinal cord, and also in other areas such as your arms and legs. Treatments often include medicines and surgery.
