+### Uncoverage Highlighting
+
+`fqm-execution` can also generate highlighted HTML that indicate which pieces of the measure logic did NOT have a "truthy" value during calculation. This is the complement to coverage. Clauses that are not covered will be highlighted red.
+
+HTML strings are returned for each group defined in the `Measure` resource in the lookup object,`groupClauseUncoverageHTML`, which is structured similarly to Group Clause Coverage.
+
+```typescript
+import { Calculator } from 'fqm-execution';
+
+const { results, groupClauseUncoverageHTML } = await Calculator.calculate(measureBundle, patientBundles, {
+ calculateClauseUncoverage: true /* false by default */
+});
+
+// groupClauseUncoverageHTML
+/* ^?
+ {
+ 'population-group-1': '<div><h2> population-group-1 Clause Uncoverage: X of Y clauses</h2> ...'
+ ...
+ }
+
+
+*/
+```
+
+### Coverage Details
+
+Details on clause coverage can also be returned. This includes a count of how many clauses there are, how many are covered and uncovered, and information about which clauses are uncovered.
+
+This information is returned for each group defined in the `Measure` resource in the lookup object,`groupClauseCoverageDetails`, which maps `group ID -> coverageDetails`. See example below for structure of this object.
+
+```typescript
+import { Calculator } from 'fqm-execution';
+
+const { results, groupClauseCoverageDetails } = await Calculator.calculate(measureBundle, patientBundles, {
+ calculateCoverageDetails: true /* false by default */
+});

 ### Clause Coverage of Null and False Literal Values
 
 Since clause coverage calculation and highlighting are based on whether individual pieces of the measure logic CQL were processed at all during calculation and held "truthy" values, `Null` and false `Literal`s that are processed during calculation would prevent 100% clause coverage and highlighting. In order to handle this special case, these clauses that will never hold "truthy" values will be highlighted and counted as covered if they were simply processed during calculation.
