S06.33AS is a billable diagnosis code used to specify a medical diagnosis of contusion and laceration of cerebrum, unspecified, with loss of consciousness status unknown, sequela. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024. The code is exempt from present on admission (POA) reporting for inpatient admissions to general acute care hospitals.

S06.33AS is a sequela code, includes a 7th character and should be used for complications that arise as a direct result of a condition like contusion and laceration of cerebrum unspecified with loss of consciousness status unknown. According to ICD-10-CM Guidelines a "sequela" code should be used for chronic or residual conditions that are complications of an initial acute disease, illness or injury. The most common sequela is pain. Usually, two diagnosis codes are needed when reporting sequela. The first code describes the nature of the sequela while the second code describes the sequela or late effect.

Unspecified diagnosis codes like S06.33AS 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

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

Present on Admission (POA)

S06.33AS is exempt from POA reporting - The Present on Admission (POA) indicator is used for diagnosis codes included in claims involving inpatient admissions to general acute care hospitals. POA indicators must be reported to CMS on each claim to facilitate the grouping of diagnoses codes into the proper Diagnostic Related Groups (DRG). CMS publishes a listing of specific diagnosis codes that are exempt from the POA reporting requirement. Review other POA exempt codes here.

CMS POA Indicator Options and Definitions

POA Indicator	Reason for Code	CMS will pay the CC/MCC DRG?
Y	Diagnosis was present at time of inpatient admission.	YES
N	Diagnosis was not present at time of inpatient admission.	NO
U	Documentation insufficient to determine if the condition was present at the time of inpatient admission.	NO
W	Clinically undetermined - unable to clinically determine whether the condition was present at the time of inpatient admission.	YES
1	Unreported/Not used - Exempt from POA reporting.	NO

Replacement Code

S0633AS replaces the following previously assigned ICD-10-CM code(s):

S06.339S - Contus/lac cereb, w LOC of unsp duration, sequela
