Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the M47 range.
Spondylosis
A degenerative spinal disease that can involve any part of the VERTEBRA, the INTERVERTEBRAL DISK, and the surrounding soft tissue.
About the M47 Code Range
ICD-10 code M47 covers spondylosis, a group of spinal conditions characterized by degeneration of the vertebrae and related structures. These codes specify different types and locations of spondylosis, helping medical professionals accurately document spinal degenerative diseases and their complications.
The ICD-10 code for spondylosis ranges from general spondylosis (M47) to specific forms involving anterior spinal artery compression syndromes (e.g., M47.012 for cervical region) and vertebral artery compression syndromes. Additionally, codes distinguish spondylosis that affects the spinal cord causing myelopathy (e.g., M47.12 for cervical region), or nerve root involvement known as radiculopathy (e.g., M47.22 cervical region). Some codes, like M47.81, are for spondylosis without myelopathy or radiculopathy, indicating less severe spinal degeneration. Synonyms such as anterior spinal artery compression syndrome and myelopathy due to cervical spondylosis are linked directly to these codes, guiding coders who identify conditions by common names. This coding system accurately identifies the affected spinal site, improving clinical clarity and treatment documentation.
