ICD-10-CM Code G72.3
Periodic paralysis

Billable Code
Billable codes are sufficient justification for admission to an acute care hospital when used a principal diagnosis.
| ICD-10 from 2011 - 2016

G72.3 is a billable ICD code used to specify a diagnosis of periodic paralysis. A 'billable code' is detailed enough to be used to specify a medical diagnosis.

The ICD code G723 is used to code Hypokalemic periodic paralysis

Hypokalemic periodic paralysis (hypoKPP) is a rare, autosomal dominant channelopathy characterized by muscle weakness or paralysis with a matching fall in potassium levels in the blood (primarily due to defect in a voltage-gated calcium channel). In individuals with this mutation, attacks often begin in adolescence and most commonly occur on awakening or after sleep or rest following strenuous exercise (attacks during exercise are rare), high carbohydrate meals, meals with high sodium content, sudden changes in temperature, and even excitement, noise, flashing lights and induced by cold temperatures. Weakness may be mild and limited to certain muscle groups, or more severe full body paralysis. Attacks may last for a few hours or persist for several days. Recovery is usually sudden when it occurs, due to release of potassium from swollen muscles as they recover. Some patients may fall into an abortive attack or develop chronic muscle weakness later in life. To differentiate it from Guillian Barre syndrome, deep tendon reflexes are normal and 7th cranial nerve is spared.(Citation Required) - During an attack reflexes may be decreased or absent.

Inclusion Terms:
Inclusion Terms
Inclusion Terms are a list of concepts for which a specific code is used. The list of Inclusion Terms is useful for determining the correct code in some cases, but the list is not necessarily exhaustive.
Familial periodic paralysis

Hypokalemic periodic paralysis (familial)
Myotonic periodic paralysis (familial)
Normokalemic paralysis (familial)
Potassium sensitive periodic paralysis
Code Type-1 Excludes:
Type-1 Excludes
Type-1 Excludes mean the conditions excluded are mutually exclusive and should never be coded together. Excludes 1 means "do not code here."

Periodic paralysis (exact match)

This is the official exact match mapping between ICD9 and ICD10, as provided by the General Equivalency mapping crosswalk. This means that in all cases where the ICD9 code 359.3 was previously used, G72.3 is the appropriate modern ICD10 code.
