About coding concussion

The ICD-10-CM code for concussion is S06.0X9 (Concussion with loss of consciousness of unspecified duration). The official index lists 14 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on S06.0X9.

Within S06.0X, choose S06.0X9 (with loss of consciousness of unspecified duration) only when documentation doesn't support a more specific option: without loss of consciousness (S06.0X0), with loss of consciousness of 30 minutes or less (S06.0X1) and with loss of consciousness status unknown (S06.0XA).

Codes in this range require a 7th character: A for initial encounter, D for subsequent encounter and S for sequela. Use placeholder "X" characters to fill any empty positions before the 7th character.

Use an additional code, if applicable, to identify mild neurocognitive disorders due to known physiological condition (F06.7-).
