GG0130A Q401.1Category 4b - OASIS Data Items

GG0130A. For GG0130A - Eating, a patient has had a stroke which has impacted their dominant hand. Upon admission to home health, the patient is noted to use their unaffected, non-dominant hand to feed themselves, and only requires setup/clean-up assistance. However, when asked by the OT to perform eating with the affected, dominant hand, the patient required substantial/maximal assist. These two attempts both occurred before therapeutic intervention was initiated. Which should be recorded as the patient’s baseline status for admission?

The intent of GG0130A - Eating is to assess the patient’s ability to use suitable utensils to bring food and/or liquids to the mouth and swallow food and/or liquid once the meal is placed before the patient. When assessing GG0130A - Eating, allow the patient to complete the activity of eating as independently as possible as long as they are safe.

GG0130A Q401.2Category 4b - OASIS Data Items

GG0130A. How would the following scenario for GG0130A - Eating be coded? A patient was admitted and at Start of Care (SOC) required only set up assistance for eating. The following day, the patient went to the Emergency Department and returned within 24 hours with an overall decline in status and an order for no oral intake due to dysphagia. Would we code 05 - Setup or clean-up assistance based on initial ability or code 88 - Not attempted due to medical condition or safety concerns because this is the new baseline following the decline?

The intent of GG0130A - Eating is to assess the patient’s ability to use suitable utensils to bring food and/or liquid to the mouth and swallow food and/or liquid once the meal is placed before the patient. At SOC/ROC, the self-care or mobility performance code is to reflect the patient’s baseline ability to complete the activity, prior to the benefit of services provided by your agency staff. In the scenario provided, use Code 05 - Setup or clean-up assistance for GG0130A - Eating if this represents the patient’s baseline status. Use of an “activity not attempted” code should only be used if the patient was not able to complete the activity prior to the benefit of services and the performance code cannot be determined based on patient/caregiver report, collaboration with other agency staff, or assessment of similar activities.

GG0130A Q401.3Category 4b - OASIS Data Items

GG0130A. A patient is admitted for home health services with quadriparesis from a previous spinal cord injury. Once an occupational therapist applied a universal cuff to the patient’s hand, the patient was able to eat the entire meal without further assistance. What is the performance code for GG0130A - Eating?

The intent of GG0130A - Eating is to assess the patient’s ability to use suitable utensils to bring food and/or liquid to the mouth and swallow food and/or liquid once the meal is placed before the patient. In the scenario provided, if the patient only required assistance to apply a universal cuff, and no further assistance was required during the eating activity, code 05 - Setup or clean-up assistance. This is because assistance is required prior to or following the activity, but not during the activity.

GG0130A Q401.4Category 4b - OASIS Data Items

GG0130A. A patient is independent with self-feeding but requires encouragement for adequate intake. Would the encouragement to increase food and/or fluid intake be considered when scoring GG0130A - Eating?

The intent of GG0130A - Eating is to assess the patient’s ability to use suitable utensils to bring food and/or liquid to the mouth and swallow food and/or liquid once the meal is placed before the patient. The adequacy of the patient’s nutrition or hydration is not considered for GG0130A - Eating. When coding activities in Section GG, clinicians should code based on the type and amount of assistance required allowing the patient to perform the activity as independently as possible, as long as they are safe. If the patient is able to meet the intent of the activity with no assistance (physical, verbal/nonverbal cueing, setup/clean-up) then code 06 - Independent.

GG0130C Q403Category 4b - OASIS Data Items

GG0130C. Does GG0130C - Toileting Hygiene that includes clothing adjustment before and after voiding, also include incontinence briefs and pads? Does this item include the safe retrieval of the supplies needed to perform the hygiene task?

GG0130C - Toileting Hygiene includes “the ability to maintain perineal hygiene, adjust clothes before and after voiding or having a bowel movement. If managing an ostomy, include wiping the opening but not managing equipment.” Toileting hygiene includes managing undergarments, clothing, and incontinence pad/briefs, etc., and performing perineal hygiene. If the patient can complete toileting hygiene and clothing management tasks only after a helper retrieves or sets up supplies necessary to perform included tasks, code 05 - Setup or clean-up assistance. In situations where a definitive answer to an assessing clinician’s question is not contained in published CMS OASIS guidance (OASIS Guidance Manual, Q&As, etc.), the clinician may have to rely on clinical judgment to determine how to code the item, ensuring that the response coded does not conflict with current guidance.

GG0130 Q405.50Category 4b - OASIS Data Items

GG0130F & GG0130G. How would you code items GG0130F - Upper body dressing and GG0130G - Lower body dressing if you are working with a patient who typically wears a dress or Mumu robe/dress and prefers not to wear undergarments? Can you code both of these items based on putting on and taking off a dress/Mumu alone?

We interpret your question to indicate that the patient does not wear underwear/briefs. If the patient does not wear underwear, nor any other type of clothing that just covers their lower body, code GG0130G - Lower body dressing with the appropriate “activity not attempted” code. Any assistance provided by a helper to put on or remove the dress or Mumu would be considered when coding GG0130F - Upper body dressing.

GG0130 Q405.51Category 4b - OASIS Data Items

GG0130F & GG0130G. If a patient is independent with dressing but requires supervision to gather their clothes from the closet and take them to the bed before they can get dressed, are they “independent” for dressing, “supervision” for dressing or “setup” for dressing?

The intent of the items GG0130F - Upper body dressing and GG0130G - Lower body dressing is to assess the patient’s ability to dress and undress above the waist (GG0130F) and below the waist (GG0130G); including fasteners, if applicable. It is not the type of assistance that is provided that determines Code 05 - Setup or clean-up assistance but rather when (related to the completion of the activity) the needed assistance is provided. If the assistance provided is necessary only before or after the activity is completed, and no assistance is needed during the completion of the activity, select Code 05 - Setup or clean-up assistance.

[Q&A ADDED 05/22; Previously CMS Qtrly Q&A 01/20 Q14]

GG0130G Q406Category 4b - OASIS Data Items

GG0130G. For GG0130G - Lower body dressing, if a patient is wearing a dressing gown and underwear during the first assessment, is this scenario acceptable to code lower body dressing? Or, at a visit the following day within the assessment timeframe, if the patient is wearing more items including underwear and shorts/pants, should we use this later scenario instead as a true baseline of their lower body dressing ability?

The intent of GG0130G - Lower body dressing is to assess the patient’s ability to dress and undress below the waist, including fasteners, if applicable, in clothing routinely worn by the patient. At SOC/ROC, the self-care or mobility performance code is to reflect the patient’s baseline ability to complete the activity, prior to the benefit of services provided by your agency staff. Clinicians should use clinical judgment to determine if observing the patient dress and undress in the lower body clothing (i.e., underwear) worn during the first assessment allows the clinician to adequately determine the patient’s ability to complete the activity of lower body dressing (GG0130G) in clothing routinely worn by the patient. If the clinician determines that this observation is adequate, code based on the type and amount of assistance the patient requires.

GG0130 Q450Category 4b - OASIS Data Items

GG0130 & GG0170. With the GG0130 - Self Care and GG0170 - Mobility items, does the patient need to have a caregiver available to assist? Can I be the helper on the day of assessment in lieu of a caregiver in order to determine which performance code 06 - 01 is correct instead of using an “activity not attempted”?

For the GG0130 and GG0170 items, the assessing clinician would code based on the type and amount of assistance needed to complete the activity safely, not based on the availability of such assistance. The assessing clinician can be the helper on the day of assessment in order to determine which code 06 - 01 accurately reflects the needed assistance to complete the activity, rather than using a “activity not attempted” code 07, 09, 10, or 88, solely because the patient does not have a caregiver.

GG0130 Q450.1Category 4b - OASIS Data Items

GG0130 & GG0170. Does the "day of assessment" convention apply to the GG0130 - Self-Care and GG0170 - Mobility items?

Yes, the day of assessment convention applies to GG0130 - Self-Care and GG0170 Mobility. For most OASIS items, including the function items, the time period under consideration is the “day of assessment”, which is defined as the 24 hours immediately preceding the home visit and the time spent by the clinician in the home. For GG0130 and GG0170, code the patient’s functional status based on a functional assessment that occurs at or soon after the patient’s start of care/resumption of care (SOC/ROC). The SOC/ROC function scores are to reflect the patient’s SOC/ROC baseline status and are to be based on observation of activities, to the extent possible. Other assessment strategies include coding patient functional status based on patient and/or caregiver report. When using patient or caregiver report, it is expected that the patient and caregiver are reporting on the patient’s status within the time period under consideration, (e.g., reporting on the patient’s ability to complete the car transfer within the past 24 hours).

GG0130 Q450.2Category 4b - OASIS Data Items

GG0130 & GG0170. The OASIS Guidance Manual for Section GG clarifies that Code 03 - Partial/moderate assistance indicates the helper is providing less than half the effort and Code 02 - Substantial/maximal assistance indicates the helper is providing more than half the effort. If a helper provides exactly half the effort, how would an activity be coded?

In the situation you describe the helper and patient each are providing exactly half of the effort to complete a GG activity. If the patient performs exactly half of the effort, code the activity 03 - Partial/moderate assistance.

GG0130 Q450.3Category 4b - OASIS Data Items

GG0130 & GG0170. For the GG functional items, I understand that verbal cueing during an activity would be coded 04 - Supervision or touching assistance. Can a verbal cue provided prior to the initiation of the task be considered as 05 - Setup or clean-up assistance, as long as no further cues were provided during the actual activity? For example, prior to the "Picking up an item from the floor" activity, the therapist needed to cue the patient on where to place their hand for stability; then the patient completed all of the activity safely and without any assistance or additional cues. Would this be Code 05 Setup or clean-up assistance or Code 04 - Supervision or touching assistance? Additionally, the OASIS Guidance Manual indicates via an example for chair/bed to chair transfers, that “locking chair brakes” prior to the transfer is 05 - Setup or clean-up assistance, as long as no further assistance was required during the activity. Could a verbal cue reminding a patient to lock wheelchair brakes prior to the initiation of the transfer be considered 05 - Setup or clean-up assistance as well, as long as no further cueing or touching was provided during the activity?

When assessing self-care and mobility activities, allow the patient to complete each activity as independently as possible, as long as they are safe. At Start of Care/Resumption of Care (SOC/ROC), the self-care or mobility performance code is to reflect the patient’s baseline ability to complete the activity prior to the benefit of services provided by your agency staff. This may be achieved by having the patient attempt the activity prior to providing any instruction that could result in a more independent code, and then coding based on the type and amount of assistance that was required prior to the benefit of services provided by your agency staff. Communicating the activity request (e.g., “Can you stand up from the toilet?”) would not be considered verbal cueing. If additional prompts are required in order for the patient to safely complete the activity (e.g., “Push down on the grab bar”, etc.), the assessing clinician may need to use clinical judgment to determine the most appropriate code, utilizing the Coding Section GG Activities Decision Tree found at https://www.cms.gov/Medicare/QualityInitiatives-Patient- Assessment-Instruments/HomeHealthQualityInits/HHQIOASISUserManual In the scenarios described, assuming the verbal cues were only required prior to the activity, were provided prior to the benefit of services, and no other assistance was needed in order for the patient to complete the activity safely, then the verbal cues fit the definition for Code 05 Setup or clean-up assistance.

GG0130 Q450.4Category 4b - OASIS Data Items

GG0130 & GG0170. We understand that if a patient initially refuses to attempt a GG activity during the assessment timeframe, and later agrees to perform the activity, the code which represents the patient’s actual performance will supersede the refusal code (07). If the clinical staff determine on day 1 or day 2 that the patient has a safety or medical issue which prevents them from attempting an activity, but on day 3 has progressed to the point where they can now perform the activity, would that code supersede the earlier code (88)? A patient may not be safe to attempt the activity on day 1 (their baseline prior to the benefit of services), but after two days of therapy, may then be safe to perform the activity. Which code would be reported on the OASIS: Code 88 Not attempted due to medical condition or safety concerns or a performance code 06 01?

At Start of Care/Resumption of Care (SOC/ROC), the self-care or mobility performance code is to reflect the patient’s baseline ability to complete the activity, prior to the benefit of services provided by your agency staff. Use of an “activity not attempted” code should occur only after determining that the activity is not completed prior to the benefit of services, and the performance code cannot be determined based on patient/caregiver report, collaboration with other agency staff, or assessment of similar activities. “Prior to the benefit of services” means prior to provision of any care by your agency staff that would result in more independent coding. In your scenario, if the patient’s baseline status prior to the benefit of services was that the activity could not be completed due to a medical or safety concern and the performance code could not be determined based on patient/caregiver report, collaboration with other agency staff, or assessment of a similar activity, code 88 - Not attempted due to medical condition or safety concerns, even if the patient’s status changes and they are able to complete the activity on a later day during the assessment timeframe.

GG0130 Q450.5Category 4b - OASIS Data Items

GG0130 & GG0170. When determining the appropriate performance code at Start of Care/Resumption of Care (SOC/ROC) for the GG self-care and mobility activities there are times when the patient’s baseline status may differ from their usual status during the assessment timeframe. For example: At the SOC visit when attempting to perform a sit to stand transfer, even with assist from the nurse, the patient is unable to complete the transfer due to pain. The nurse scores GG0170D - Sit to stand as Code 88 - Not attempted due to medical condition or safety concerns. During the remaining days of the SOC assessment timeframe the patient was able to perform the sit to stand transfer with the assistance of two people following intervention from the nurse and therapist. Which code would I use? Code 88 - Not attempted due to medical condition or safety concerns or Code 01 Dependent?

At Start of Care/Resumption of Care (SOC/ROC) the self-care or mobility performance code is to be based on a functional assessment that occurs at or soon after the patient’s SOC/ROC and reflect the patient’s baseline ability to complete the activity prior to the benefit of services provided by your agency staff. “Prior to the benefit of services” means prior to provision of any care by your agency staff that would result in more independent coding. When the baseline function code differs from the usual performance during the assessment timeframe, report the baseline function code. If in your scenario, the patient being unable to complete the sit to stand activity due to medical condition or safety concerns represents their baseline ability, then code 88 - Not attempted due to medical condition or safety concerns.

GG0130 Q450.6Category 4b - OASIS Data Items

GG0130 & GG0170. The guidance for GG0130 - Self Care and GG0170 - Mobility states “the assessing clinician would code each activity based on the type and amount of assistance required to complete the activity safely, not based on the availability of such assistance”. Can you provide an example of “not based on the availability of such assistance?”

When assessing and coding GG activities allow the patient to perform the activity as independently as possible, as long as they are safe. As stated, code based on the type and amount of assistance required to complete the activity, not based on the availability of assistance. For example, a patient requires a physical therapist to provide assistance to ambulate 10 feet safely. However, when the therapist is not available, the patient is unable to ambulate 10 feet safely. The walking activity would be coded based on the type and amount of assistance required (assistance to walk 10 feet), even though a physical therapist may not always be available to provide the needed assistance.
