What Hypomagnesemia ICD-10 codes can I use?
If you’re looking for Hypomagnesemia ICD codes, here are five that you can use:
- E83.42 - Hypomagnesemia
This ICD-10 code is meant to be used on a patient confirmed to have Hypomagnesemia. This is the main ICD-10 code you’re looking for.
- P71.2 - Neonatal hypomagnesemia
This is the same as Item 1, but this time, it’s meant to be used on a newborn patient. Please note that the neonatal period of a newborn is the first four weeks of their life after being birthed.
- T50.905A - Adverse effect of unspecified drugs, medicaments and biological substances, initial encounter
This ICD-10 code is meant to be used on a patient confirmed to be dealing with an adverse effect of a particular drug, medicament, or biological substance. If your patient has Hypomagnesemia due to any of these, you can use this ICD-10 code.
This comes with the initial encounter label, which means the patient is receiving active care for it.
- T50.905D - Adverse effect of unspecified drugs, medicaments and biological substances, subsequent encounter
This is the same as Item 3, but this time, it comes with a subsequent encounter label. This means they are recovering from the problem and still receiving active/routine care for it.
- T50.905S - Adverse effect of unspecified drugs, medicaments and biological substances, sequela
This is the same as Item 3, but this time, it comes with a sequela label, which means they are dealing with the aftereffects of the problem.
Given this, this ICD-10 code should be accompanied by two other ICD-10 codes, one of which should designate the sequela’s nature, while the other should describe the sequela (meaning its effects).
