Subluxation of unspecified cervical vertebrae, init encntr

This code signifies a partial dislocation or misalignment of one or more cervical vertebrae where the specific vertebral level is not documented. It indicates that this is the first time the patient is being treated for this particular injury.

Apply this code when documentation clearly states a cervical subluxation but does not specify which cervical vertebra (e.g., C1, C2, etc.) is affected. This code is appropriate for the initial phase of active treatment for the injury.

• Ensure "initial encounter" is explicitly documented for the current treatment episode.
• Avoid using this code if a specific cervical vertebral level (e.g., C1, C2-C3) is identified; instead, use a more specific S13.1- code.
• Do not use for follow-up care or sequelae; refer to subsequent or sequela encounter codes for those scenarios.
