Properties Code URL Description Type conversion-factor Defines the conversion factor for a specific ingredient, when the conversion factor is the same for all dose forms and dose amounts for the ingredient. The value of this property will be the decimal representation of the conversion factor. decimal dose-form-conversion-factor Defines the conversion factor for an ingredient when the conversion factor varies by the dose form of the medication. The value of this property will be a string of the form <dose-form-code>:<conversion-factor>[@<doses-per-day>], e.g. 970789:130, where '970789' is the RxNorm dose form code, and '130' is the decimal representation of the conversion factor. An example of a per-day conversion factor is fentanyl, 316987:7200@0.33333333, where 316987 is RxNorm dose form code, 7200 is the conversion factor, and 0.33333333 is the dosesPerDay, expressed as a decimal with a maximum of 8 digits after the decimal. string dose-range-conversion-factor Defines the conversion factor for an ingredient when the conversion factor varies by the overall dose of the medication. The value of this property will be a string of the form <low-value>-<high-value>:<conversion-factor>, e.g. 1-20:4. Note that the low-value or high-value may be a wildcard '*' to indicate the range continues (e.g. '61-*:12' indicates the range is 61 or greater). string Code Display 1819 Buprenorphine 1841 Butorphanol 2670 Codeine 23088 Dihydrocodeine 4337 Fentanyl 5489 Hydrocodone 3423 Hydromorphone 237005 Levomethadyl acetate 6378 Loverphanol tartrate 6754 Meperidine 6813 Methadone 7052 Morphine 7676 Opium 7804 Oxycodone 7814 Oxymorphone 8001 Pentazocine 787390 Tapentadol 10689 Tramadol
This Code System Supplement defines conversion factors for calculating Morphine Milligram Equivalence (MME) using conversion factors used by default for the CDS4CPM Project. The supplement defines conversions factors for ingredients in one of 3 ways: 1, as a direct conversion factor for the ingredient, 2, as a dose-form-specific conversion factor for the ingredient, and 3, as a dose-ranged conversion factor for the ingredient. See the descriptions for each property for information on how the values are represented for the different conversion factors. For a given ingredient, only one type of property will be present, and the properties will enable a unique conversion factor to be determined if the input is within the expected range. If the input is outside the expected range, implementations should indicate a conversion factor could not be determined from the supplied information. All conversion factors supplied in this supplement are in 'mg/d'.
