Replace ICD-9-CM with ICD-10-PCS

Impacts: First Pass of a Mechanical Reperfusion Device

http://www.cms.gov/Medicare/Coding/ICD10/2015-ICD-10-CM-and-GEMs.html



Rationale: This change is to provide additional inclusion terms for abstraction of first pass /deployment of a clot retrieval device. Description of Changes: Inclusion Guidelines for Abstraction: Add:

Access Advance Aspiration Attempt Run

Impacts: ICD-10-PCS Other Procedure Times

Rationale: This change is to provide abstractor clarification about time documentation for procedures performed at the bedside. Description of Changes: Notes for Abstraction: Add: For bedside procedures, e.g. external ventricular drain (EVD) placement, the time

documented on the bedside flow sheet / nursing note should be used if earlier than other times documented on a procedure record or in other sources.

Suggested Data Sources: Add:

Bedside flow sheet ICU notes Nursing notes Nursing flow sheet Operative notes

Inclusion Guidelines for Abstraction: Change to: 1. Locate an inclusion term in a suggested data source in no particular order. Use the earliest time associated with an inclusion term that represents the ICD-10-PCS Other Procedure Time(s). 2. If no inclusion terms are found on any suggested data source, look for alternative terms associated with the procedure start time. If none are found, other sources can be used in no particular order. Use the earliest time that represents the ICD-10-PCS Other Procedure Time(s). * Procedure start * Procedure begin * Procedure initiated



Impacts: ICD-10-PCS Principal Procedure Time

Rationale: This change is to provide abstractor clarification about time documentation for procedures performed at the bedside. Description of Changes: Notes for Abstraction: Add: For bedside procedures, e.g. external ventricular drain (EVD) placement, the time

documented on the bedside flow sheet / nursing note should be used if earlier than other times documented on a procedure record or in other sources.

Suggested Data Sources: Add:

Bedside flow sheet ICU notes Nursing notes Nursing flow sheet Operative notes

Inclusion Guidelines for Abstraction: Change to: 1. Locate an inclusion term in a suggested data source in no particular order. Use the earliest time associated with an inclusion term that represents the ICD-10-PCS Other Procedure Time(s). 2. If no inclusion terms are found on any suggested data source, look for alternative terms associated with the procedure start time. If none are found, other sources can be used in no particular order. Use the earliest time that represents the ICD-10-PCS Other Procedure Time(s). * Procedure start * Procedure begin * Procedure initiated

Impacts: Initial Hunt and Hess Scale Performed

Rationale: This change is to provide abstractor clarification about Hunt and Hess scale documentation. Description of Changes: Notes for Abstraction: Change to: The Hunt and Hess scale may be documented by the physician/APN/PA or nurse

(RN).



Hunt and Hess obtained by teleneurology and documented in the medical record, select 'YES'.

Impacts: Initial Hunt and Hess Scale Time

Rationale: This change is to provide abstractor clarification about Hunt and Hess scale time documentation. Description of Changes: Notes for Abstraction: Add new second bullet: If the time of the first Hunt and Hess is a time prior to hospital arrival because the

score was obtained by teleneurology, use the Arrival Time for the score time. Change 4th bullet to:

Initial Hunt and Hess Scale Time refers to the time that the first Hunt and Hess Scale was performed. If the time performed is mentioned in the body of a note, select the time performed rather than the time stamp on the note. If the only time documented with the scale is the time stamp on the note, then select the time stamped. Examples:

o Documentation indicates that the initial Hunt and Hess scale was done at 0920. Time stamp on the note is 1159. The abstractor should select 0920 for Initial Hunt and Hess Scale Time.

o Documentation indicates that the Hunt and Hess done on arrival was III. Patient arrived at your hospital 2100. Time stamp on the note is 2136. The abstractor should select 2100 for Initial Hunt and Hess Scale Time.

o Hunt & Hess 3 [no time] documented. Time stamp on the note is 1513. The abstractor should select 1513 for Initial Hunt and Hess Scale Time.

Impacts: Initial ICH Score Performed

Rationale: This change is to provide abstractor clarification about ICH score documentation. Description of Changes: Notes for Abstraction: Change to: The ICH score may be documented by the physician/APN/PA or nurse (RN). ICH score obtained by teleneurology and documented in the medical record, select

'YES'. If a total ICH score (i.e., sum of the component points) is documented, select

‘YES’.



If components are scored but the total ICH score is not documented or left blank, select ‘NO’. Do not infer a total ICH score from documented component scores.

Impacts: Initial ICH Score Time

Rationale: This change is to provide abstractor clarification about ICH score time documentation. Description of Changes: Notes for Abstraction: Add new second bullet: If the time of the first ICH score is a time prior to hospital arrival because the score

was obtained by teleneurology, use the Arrival Time for the score time. Change 4th bullet to:

Initial ICH Score Time refers to the time that the first ICH score was performed. If the time performed is mentioned in the body of a note, select the time performed rather than the time stamp on the note. If the only time documented with the score is the time stamp on the note, then select the time stamped. Examples:

o Documentation indicates that the initial ICH score was done at 0920. Time stamp on the note is 1159. The abstractor should select 0920 for Initial ICH Score Time.

o Documentation indicates that the ICH score done on arrival was 5. Patient arrived at your hospital 2100. Time stamp on the note is 2136. The abstractor should select 2100 for Initial ICH Score Time.

o ICH score 5 [no time] documented. Time stamp on the note is 1513. The abstractor should select “1513 for Initial ICH Score Time.

Impacts: Initial NIHSS Score Time

Rationale: This change is to provide abstractor clarification about NIHSS score time documentation. Description of Changes: Notes for Abstraction: Add new second bullet: If the time of the first NIHSS score is a time prior to hospital arrival because the

score was obtained by teleneurology, use the Arrival Time for the score time.

Change 4th bullet to: Initial NIHSS Score Time refers to the time that the first NIHSS score was

performed. If the time performed is mentioned in the body of a note, select the time performed rather than the time stamp on the note. If the only time documented with the score is the time stamp on the note, then select the time stamped. Examples:



o Documentation indicates that the initial NIHSS score was done at 0920. Time stamp on the note is 1159. The abstractor should select 0920 for Initial NIHSS Score Time.

o Documentation indicates that the NIHSS score done on arrival was 12. Patient arrived at your hospital 2100. Time stamp on the note is 2136. The abstractor should select 2100 for Initial NIHSS Score Time.

o NIHSS score 12 [no time] documented. Time stamp on the note is 1513. The abstractor should select 1513 for Initial NIHSS Score Time.

Impacts: Nimodipine Administration

Rationale: This change is to include an oral suspension form of nimodipine (Nymalize), FDA approved in May, 2013, as an inclusion term for abstraction, and provide clarification about the timeframe for abstraction of nimodipine administration. Description of Changes: Notes for Abstraction: Change to:

Nimodipine treatment must be administered at this hospital within the first 24 hours of arrival to select 'YES'. It is not necessary to review documentation outside of this timeframe.

If nimodipine was administered at another hospital and the patient was subsequently transferred to this hospital and nimodipine treatment continued on admission to this hospital, select ‘YES'

If nimodipine was administered at this hospital later than the first 24 hours after arrival, select 'NO'.

If nimodipine was administered at another hospital and the patient was subsequently transferred to this hospital and nimodipine treatment was not resumed or discontinued, select 'NO'.

A physician order for nimodipine that is not executed, select ‘NO'. Inclusion Guidelines for Abstraction: Add: Nymalize

Impacts: Post-Treatment Thrombolysis in Cerebral Infarction (TICI) Reperfusion Grade

Rationale: This change is to provide abstractor clarification about TICI documentation. Description of Changes: Notes for Abstraction: Change to: The TICI grade may be documented by the physician/APN/PA, or a nurse (RN),

circulating nurse, or operating room technician designated to scribe during the procedure.



When multiple TICIs are documented because more than one vessel or branches of an artery are occluded, select the TICI grade associated with the site of primary vessel occlusion.

If unable to determine whether the TICI reflects reperfusion of the primary vessel, then select "UTD".

Impacts: Proximal or Distal Occlusion

Rationale: This change is to increase the accuracy for abstraction of proximal clots associated with higher risk and poorer outcomes. Description of Changes: Definition: Change to: Documentation in the medical record of the location of the clot in either the large arteries in the neck or base of the brain (proximal), or small arteries higher up in the brain (distal). Arterial occlusions arising more proximally are associated with poorer outcomes. Allowable Values: Change to: 1 Proximal cerebral occlusion 2 Distal cerebral occlusion 3 Neither proximal or distal, OR unable to determine (UTD) from the medical record documentation Notes for Abstraction: Change to: If the occlusion is documented in an artery listed as an inclusion term for

"proximal", select ‘1’. If the occlusion is documented in an artery listed as an inclusion term for "distal",

select ‘2’. If multiple occlusions, select "proximal" or "distal" for the primary vessel occlusion. If unable to determine, select ‘3’.

Inclusion Guidelines for Abstraction: Add: PROXIMAL: Internal Carotid Artery (ICA) ICA terminus Middle Cerebral Artery (MCA) Middle Cerebral Artery (MCA) M1 segment



M1 T-occlusion (T-lesion) Vertebral Artery Basilar Artery

DISTAL: Anterior Cerebral Artery (ACA) Anterior Cerebral Artery (ACA) A1 segment A1 Anterior Cerebral Artery (ACA) A2 segment A2 Anterior Cerebral Artery (ACA) A3 segment A3 Middle Cerebral Artery (MCA) M2 segment M2 Middle Cerebral Artery (MCA) M3 segment M3 Middle Cerebral Artery (MCA) M4 segment M4 Posterior Cerebral Artery (PCA) Posterior Cerebral Artery (PCA) P1 segment P1 Posterior Cerebral Artery (PCA) P2 segment P2 Posterior Cerebral Artery (PCA) P3 segment P3

Impacts: Reason for Not Administering Nimodipine Treatment

Rationale: This change is to provide stand-alone reasons for not administering nimodipine. Description of Changes: Definition: Add:

Non-aneurysmal subarachnoid hemorrhage (SAH) Reversible cerebral vasoconstriction syndrome Cerebral amyloid angiopathy

Notes for Abstraction:



Add: The following are acceptable as stand-alone reasons for not administering

nimodipine treatment – Nimodipine linkage is not needed: o Non-aneurysmal subarachnoid hemorrhage (SAH) o Reversible cerebral vasoconstriction syndrome o Cerebral amyloid angiopathy

Impacts: Site of Primary Vessel Occlusion

Rationale: Correct typos. Description of Changes: Format Change to: Length: 2 Allowable Values Change to: 4 Internal carotid artery (ICA) 5 ICA terminus (T-lesion; T-occlusion)
