2022 ICD-10-CM Code D42.9

Neoplasm of uncertain behavior of meninges, unspecified

Version 2021

Valid for Submission

ICD-10:D42.9
Short Description:Neoplasm of uncertain behavior of meninges, unspecified
Long Description:Neoplasm of uncertain behavior of meninges, unspecified

Code Classification

  • Neoplasms (C00–D48)
    • Neoplasms of uncertain behavior, polycythemia vera and myelodysplastic syndromes (D37-D48)
      • Neoplasm of uncertain behavior of meninges (D42)

D42.9 is a billable diagnosis code used to specify a medical diagnosis of neoplasm of uncertain behavior of meninges, unspecified. The code D42.9 is valid during the fiscal year 2022 from October 01, 2021 through September 30, 2022 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 .

Unspecified diagnosis codes like D42.9 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:

The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code D42.9 its ICD-9 equivalent. The approximate mapping means there is not an exact match between the ICD-10 code and the ICD-9 code and the mapped code is not a precise representation of the original code.

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

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.
