What perinephric hematoma ICD codes can I use?
If you're having trouble looking for ICD codes for perinephric hematoma, no ICD codes mention perinephric hematoma in their names. That doesn't mean there aren't any, though. Perinephric hematoma is a problem tied to the abdomen and kidneys, so here are four ICD codes that are most suited to it:
K66.1 - Hemoperitoneum
This ICD code is for a patient confirmed to have hemoperitoneum, a type of internal bleeding in the peritoneum that can result from perinephric hematoma.
S37.009A - Unspecified injury of unspecified kidney, initial encounter
This ICD-10 code is meant to be used on a patient confirmed to have an unspecified type of injury to an unspecified kidney. Perinephric hematoma is a kind of kidney injury, so that you may use this ICD code. This code also has an initial encounter label on it, which means the patient is being given active treatment for it.
S37.009D - Unspecified injury of unspecified kidney, subsequent encounter
This is the same as Item 2, but this time, there's a subsequent encounter label, which means that the patient is recovering from the problem and still being active/routine care.
S37.009S - Unspecified injury of unspecified kidney, sequela
This is the same as Item 2, but this time, there's a sequela label on it, which means that the patient is 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).
Do note that items 2-4 have variations. These variations are more specific, meaning they mention which kidney has the problem. If you can determine which kidney is affected, it's best to use the particular ICD codes for it. Given the lack of perinephric hematoma ICD codes, using the unspecified injury of [unspecified/left/right] kidney is best.
