Lund-Mackay CT Sinus Score
Quantifies sinus disease severity on CT to support surgical indication
- Highest activation tier
- Recommended
- How it is scored
- Scored in code; a stated value is compared only from the structured summary or a supplied value
- Scoring type
- questionnaire
- Care settings
- Inpatient, Outpatient
When it activates
Scribeable activates a calculator from the encounter. The Lund-Mackay CT Sinus Score can activate when the transcript or pasted chart context documents any of these:
- Sinus CT interpretation
- Chronic sinusitis surgical planning
- Sinus disease severity quantification
A coded diagnosis can also activate it. ICD-10 prefixes carried by the registry: J32.
Inputs the note needs
1 input. Each is resolved from the transcript, the pasted chart context and charted labs; at this calculator’s tier a missing input is never requested, and a missing required input keeps the score out of the draft.
| Input | Type | Unit / options | Guidance |
|---|---|---|---|
| Lund-Mackay score (0-24) | exam |
Scoring
12 sinus groups (bilateral), each scored 0 (clear), 1 (partial opacification), 2 (total opacification). Total 0-24.
Interpretation
0: Normal. 1-4: Minimal disease. 5-12: Moderate disease. >12: Severe disease — surgery often indicated.

How Scribeable handles it in the note
When an encounter activates the Lund-Mackay CT Sinus Score (its highest tier is recommended), Scribeable does not ask you for missing inputs. The score is computed in code from whatever inputs resolve from the transcript, the pasted chart context or charted labs; a computed value is written into the draft only when every required input already resolves.
The score is computed in code from the resolved inputs, not recalled by the language model. A stated Lund-Mackay CT Sinus Score value is compared against the computed one when the draft's structured summary carries it; a disagreement found there is flagged to the second drafting pass, which is instructed to correct the score and its interpretation, unless Scribeable has supplied the computed value to that pass, in which case the value the draft writes is checked against the supplied one and a detected difference is shown beside the note for you to adjudicate rather than silently rewritten.
Classified as a staging or classification system: activated strictly, because a wrong stage on the wrong patient is a documentation hazard.
