This code system http://ehealth.sundhed.dk/cs/device-measuring-quality defines the following codes:
| Lvl | Code | Display | Definition |
| 1 | none | No quality needed | Quality value where no derivation rule logic nor values are expected |
| 2 | unknown | Unknown quality | Unknown quality (Unlikely to be adequate if a quality value is expected) |
| 3 | derivation-error | Error in deriving or determining the quality | Quality value could not be derived due to insufficient input, unknown/unavailable logic, or other error |
| 4 | normal | Normal/neutral device measuring quality | Normal/neutral device measuring quality |
| 5 | low-precision | Low precision/credibility grade device quality | Low precision/credibility grade device quality. Typically such device is not clinical grade. |
| 6 | low-precision-degraded | Degraded quality for low precision/credibility grade device | Degraded quality for low precision/credibility grade device. Typically such device is not clinical grade. |
| 7 | low-precision-normal | Normal/neutral quality for low precision/credibility grade device | Normal/neutral quality for low precision/credibility grade device. Typically such device is not clinical grade. |
| 8 | low-precision-uncalibrated | Quality for uncalibrated low precision/credibility grade device | Quality for uncalibrated low precision/credibility grade device. Typically such device is not clinical grade. |
| 9 | low-precision-calibrated | Quality for calibrated low precision/credibility grade device | Quality for calibrated low precision/credibility grade device. Typically such device is not clinical grade. |
| 10 | high-precision | High precision/credibility grade device quality | High precision/credibility grade device quality. Typically such device is clinical grade. |
| 11 | high-precision-degraded | Degraded quality for high precision/credibility grade device | Degraded quality for high precision/credibility grade device. Typically such device is clinical grade. |
| 12 | high-precision-normal | Normal/neutral quality for high precision/credibility grade device | Normal/neutral quality for high precision/credibility grade device. Typically such device is clinical grade. |
| 13 | high-precision-uncalibrated | Quality for uncalibrated high precision/credibility grade device | Quality for uncalibrated high precision/credibility grade device. Typically such device is clinical grade. |
| 14 | high-precision-calibrated | Quality for calibrated high precision/credibility grade device | Quality for calibrated high precision/credibility grade device. Typically such device is clinical grade. |
| 1 | TBD | Example value - Under construction | Example value - Under construction |
