Malignant neoplasms of eye, brain and other parts of central nervous system (C69-C72)

The ICD-10 codes in the range C69-C72 classify malignant tumors that affect the eye, brain, meninges, spinal cord, cranial nerves, and other parts of the central nervous system. These codes cover specific malignant neoplasms such as those of the conjunctiva, retina, orbit, various brain lobes, meninges, and cranial nerves, helping to specify the exact site and nature of the cancer.

This code range includes detailed classifications for malignant neoplasms of the eye and adnexa (C69), addressing tumors of structures like the conjunctiva, cornea, retina, choroid, and lacrimal glands, with distinctions made for right, left, or unspecified sites. Several synonyms such as "squamous cell carcinoma of conjunctiva" or "retinoblastoma" correspond to specific codes, aiding coders in linking colloquial or clinical names to proper classifications. The codes for meninges (C70) and brain tumors (C71) cover all main brain regions including frontal, temporal, occipital lobes, and cerebellum, reflecting types like glioblastoma or astrocytoma. The range also includes codes for malignant neoplasms of spinal cord, cranial nerves, and other central nervous system parts (C72), specifying tumors in nerves such as the optic, acoustic, and olfactory nerves. This structure supports precise coding necessary for diagnosis, treatment planning, or research concerning malignant central nervous system tumors and eye cancers.
