Watch out: Careful of what seventh character you apply.
Neck sprain means that the patient presents with damage to the ligaments of the neck. To report the correct code you must specify which ligaments/joints were sprained in the neck.
Here are your options:
Each of these codes requires a 7th character: A (initial counter), D (subsequent encounter), or S (sequela), says Peggy Stilley, CPC, CPC-I, CPMA, CPB, COGBC, revenue integrity auditor for Oklahoma Sports Orthopedics Institute in Norman.
Documentation: The provider probably already specifies which ligaments/joints were sprained in the neck, but now you have codes to reflect that.
The provider may simply document sprain of ligaments of cervical spine as “sprain of anterior longitudinal (ligament), cervical,” “sprain of atlanto-axial (joints),” “sprain of atlanto-occipital (joints),” or “whiplash injury of cervical spine.”
Heads up: Don’t always reach for the unspecified code. You should always code to the highest specificity.

Coding tips: You will see an Exclude2 note under S13 stating that you may report this code with a strain of muscle or tendon at neck level (S16.1) code, but your physician needs to document both conditions.
If you’re seeing a patient for a worker’s compensation claim, you may have to apply an old ICD-9 code, which would be 847.0 (Neck sprain).
