S12.15 is the authoritative medical code for Other traumatic spondylolisthesis of second cervical vertebra. This classification is used in medical billing and clinical recording to specify the clinical criteria for other traumatic spondylolisthesis of second cervical vertebra (ICD-10-CM S12.15), ensuring healthcare documentation aligns with 2026 federal coding standards.
Billing Status: NO. This is a clinician non-billable / parent hierarchy grouping in the ICD-10-CM system.
Official Registry Overview & Definition
Other traumatic spondylolisthesis of second cervical vertebra is a non-billable ICD-10-CM category code S12.15. A more specific billable subcode must be selected for claims submission. Includes: fracture of cervical neural arch; fracture of cervical spine; fracture of cervical spinous process; fracture of cervical transverse process; fracture of cervical vertebral arch; fracture of neck; injuries of nape; injuries of supraclavicular region; injuries of throat. Excludes2 (not included here): burns and corrosions T20-T32; effects of foreign body in esophagus T18.1; effects of foreign body in larynx T17.3; effects of foreign body in pharynx T17.2; effects of foreign body in trachea T17.4; frostbite T33-T34; insect bite or sting, venomous T63.4. Code first: any associated cervical spinal cord injury (S14.0, S14.1-). 7th character: The appropriate 7th character is to be added to all codes from subcategories S12.0-S12.6.

Frequently Asked Questions (FAQ) & Clinical Guidance
Can S12.15 be billed directly?
No. S12.15 (Other traumatic spondylolisthesis of second cervical vertebra) is a non-billable ICD-10-CM category code. A more specific billable subcode must be selected based on clinical documentation.
Does S12.15 require a 7th character?
Yes. The appropriate 7th character is to be added to all codes from subcategories S12.0-S12.6.
Can S12.15 be reported alongside related conditions?
Per Excludes2 instructions, S12.15 and the following may both be reported when both are present: burns and corrosions (T20-T32); effects of foreign body in esophagus (T18.1); effects of foreign body in larynx (T17.3); effects of foreign body in pharynx (T17.2).
Does S12.15 need to be sequenced after another code?
