About coding Adynamia
The ICD-10-CM code for Adynamia is G72.3 (Periodic paralysis).
Within G72 (other and unspecified myopathies), G72.3 is specifically for periodic paralysis. Related codes cover drug-induced myopathy (G72.0), alcoholic myopathy (G72.1), myopathy due to other toxic agents (G72.2), inflammatory and immune myopathies, not elsewhere classified (G72.4), other specified myopathies (G72.8) and myopathy, unspecified (G72.9).
Don't report G72.3 together with the conditions in its Excludes1 note: paramyotonia congenita (of von Eulenburg) (G71.19).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
Don't confuse with (Excludes1 for G72.3)
- paramyotonia congenita (of von Eulenburg) (G71.19)
