Valid for Submission
S06.820D is a billable diagnosis code used to specify a medical diagnosis of injury of left internal carotid artery, intracranial portion, not elsewhere classified without loss of consciousness, subsequent encounter. The code S06.820D is valid during the fiscal year 2021 from October 01, 2020 through September 30, 2021 for the submission of HIPAA-covered transactions. The code is exempt from present on admission (POA) reporting for inpatient admissions to general acute care hospitals.
S06.820D is a subsequent encounter code, includes a 7th character and should be used after the patient has completed active treatment for a condition like injury of left internal carotid artery intracranial portion not elsewhere classified without loss of consciousness. According to ICD-10-CM Guidelines a "subsequent encounter" occurs when the patient is receiving routine care for the condition during the healing or recovery phase of treatment. Subsequent diagnosis codes are appropriate during the recovery phase, no matter how many times the patient has seen the provider for this condition. If the provider needs to adjust the patient's care plan due to a setback or other complication, the encounter becomes active again.

- S - sequela
Diagnostic Related Groups - MS-DRG Mapping
The ICD-10 code S06.820D is grouped in the following groups for version MS-DRG V38.0 What are Diagnostic Related Groups?
The Diagnostic Related Groups (DRGs) are a patient classification scheme which provides a means of relating the type of patients a hospital treats. The DRGs divides all possible principal diagnoses into mutually exclusive principal diagnosis areas referred to as Major Diagnostic Categories (MDC). applicable from 10/01/2020 through 09/30/2021.
Present on Admission (POA)
S06.820D 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 Code | POA 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 |

Information for Patients
Traumatic Brain Injury
Also called: Acquired brain injury, TBI
Traumatic brain injury (TBI) happens when a bump, blow, jolt, or other head injury causes damage to the brain. Every year, millions of people in the U.S. suffer brain injuries. More than half are bad enough that people must go to the hospital. The worst injuries can lead to permanent brain damage or death. Half of all TBIs are from motor vehicle accidents. Military personnel in combat zones are also at risk.
Symptoms of a TBI may not appear until days or weeks following the injury. A concussion is the mildest type. It can cause a headache or neck pain, nausea, ringing in the ears, dizziness, and tiredness. People with a moderate or severe TBI may have those, plus other symptoms:
- A headache that gets worse or does not go away
- Repeated vomiting or nausea
- Convulsions or seizures
- Inability to awaken from sleep
- Slurred speech
- Weakness or numbness in the arms and legs
- Dilated eye pupils
Health care professionals use a neurological exam and imaging tests to assess TBI. Serious traumatic brain injuries need emergency treatment. Treatment and outcome depend on how severe the injury is. TBI can cause a wide range of changes affecting thinking, sensation, language, or emotions. TBI can be associated with post-traumatic stress disorder. People with severe injuries usually need rehabilitation.
