S06.33AA is a billable diagnosis code used to specify a medical diagnosis of contusion and laceration of cerebrum, unspecified, with loss of consciousness status unknown, initial encounter. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

S06.33AA is an initial encounter code, includes a 7th character and should be used while the patient is receiving active treatment for a condition like contusion and laceration of cerebrum unspecified with loss of consciousness status unknown. According to ICD-10-CM Guidelines an "initial encounter" doesn't necessarily means "initial visit". The 7th character should be used when the patient is undergoing active treatment regardless if new or different providers saw the patient over the course of a treatment. The appropriate 7th character codes should also be used even if the patient delayed seeking treatment for a condition.

Unspecified diagnosis codes like S06.33AA are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Approximate Synonyms

The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

Brain injury with open intracranial wound AND concussion
Cerebral cortex laceration with concussion
Cerebral laceration and contusion
Contusion of cerebral cortex
Cortex laceration
Cortex laceration
Cortex laceration
Cortex laceration and contusion
Cortex laceration with open intracranial wound
Cortex laceration with open intracranial wound
Cortex laceration with open intracranial wound AND concussion
Focal brain laceration
Focal laceration of cerebrum
Laceration of cerebrum

Clinical Classification

Clinical Category is Traumatic brain injury (TBI); concussion, initial encounter
CCSR Category Code: INJ008
Inpatient Default CCSR: Y - Yes, default inpatient assignment for principal diagnosis or first-listed diagnosis.
Outpatient Default CCSR: Y - Yes, default outpatient assignment for principal diagnosis or first-listed diagnosis.

Coding Guidelines

The appropriate 7th character is to be added to each code from block Intracranial injury (S06). Use the following options for the aplicable episode of care:

A - initial encounter
D - subsequent encounter
S - sequela

Code Edits

The Medicare Code Editor (MCE) detects and reports errors in the coding of claims data. The following ICD-10-CM Code Edits are applicable to this code:

Unspecified codes - Unspecified codes exist in the ICD-10-CM classification for circumstances when documentation in the medical record does not provide the level of detail needed to support reporting a more specific code. However, in the inpatient setting, there should generally be very limited and rare circumstances for which the laterality (right, left, bilateral) of a condition is unable to be documented and reported. The following pages contain the list of unspecified ICD-10-CM diagnosis codes for which there is a more specific code to identify laterality (right, left, bilateral) within that code family.

Replacement Code

S0633AA replaces the following previously assigned ICD-10-CM code(s):

S06.339A - Contus/lac cereb, w LOC of unsp duration, init

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
