LITERAL EVIDENCE / DETERMINISTIC RULE CONTEXT / HUMAN CONTROL
Does the documentation support the result?
MDS/PDPM supporting documentation should let a reviewer follow the reasoning back to the source. These synthetic examples show the difference between an observed fact and a complete coding determination.
CHARTTRACE RESOURCES • FOUR SYNTHETIC EXAMPLES · NO PATIENT DATA
Read the sentence. Keep the limitation.
A source statement can support a narrow fact while leaving the assessment response unresolved. ChartTrace’s evidence-first approach keeps that limitation visible alongside the relevant rule context.
These are original educational examples, not actual ChartTrace customer records, clinical advice, payer-specific legal advice or approved coding results.
EXAMPLE 01 / SYNTHETIC
A specific assistance statement
Supported observation
SOURCE SENTENCE
Staff provided verbal cues only; no physical assistance was needed.
Only the displayed text is established for this example.
Assessment / coding issue
Oral hygiene / Section GG
Rule and review context
The excerpt specifies the assistance observed. Compare it with the applicable Section GG instructions and the complete assessment context.
The statement supports that verbal cueing occurred during this observation. It does not establish usual performance across the assessment period or approve a final code.
Human next step
Confirm timing, other relevant observations and any conflicting support before deciding.
EXAMPLE 02 / SYNTHETIC
Assistance without a description
Insufficient detail
SOURCE SENTENCE
Assistance was provided with oral hygiene.
Only the displayed text is established for this example.
Assessment / coding issue
Assistance level / MDS accuracy review
Rule and review context
“Assistance” does not explain whether the task involved cueing, setup, touching or physical help. A reviewer needs the underlying detail.
The sentence supports that some help occurred. It is insufficient to distinguish the assistance level for the coding question.
Human next step
Request clarification through the facility’s secure process. Do not fill the gap with an assumed level of assistance.
EXAMPLE 03 / SYNTHETIC
A diagnosis in the past tense
Insufficient current support
SOURCE SENTENCE
History of pneumonia during a prior hospital stay.
Only the displayed text is established for this example.
Assessment / coding issue
Diagnosis support / current MDS response
Rule and review context
A historical mention and a currently applicable diagnosis are different questions. Review the documentation and timing requirements for the specific assessment item.
This excerpt establishes a historical mention. It does not establish that the diagnosis meets the item’s current requirements.
Human next step
Review the relevant provider documentation and active-status criteria. A qualified reviewer resolves applicability; the excerpt alone cannot.
EXAMPLE 04 / SYNTHETIC
Two observations that do not agree
Needs human review
SOURCE SENTENCE
Note A: “Toothbrushing completed without help.” Note B: “Staff provided physical help with toothbrushing.”
Only the displayed text is established for this example.
Assessment / coding issue
Conflicting assistance observations
Rule and review context
First determine whether the observations concern the same activity and relevant assessment period. The difference could reflect a real change or incomplete context.
The two statements should remain visible together. Selecting the more favorable result or averaging the descriptions does not resolve the coding question.
Human next step
Reconcile the context and evaluate usual performance using the applicable instructions. Retain why the final decision was made.
A supported observation is not a complete PDPM classification.
PDPM classification uses assessment information beyond any one sentence. Review the contributing inputs and applicable CMS classification materials before interpreting an output or investigating a HIPPS mismatch.
Documentation also needs to support the services being billed. A matched result does not independently establish coverage or medical necessity. CMS SNF services guidance ↗ explains that broader documentation context.
