About HZ98ZZZ
HZ98ZZZ is the ICD-10-PCS code for a pharmacotherapy procedure on the psychiatric medication using a none approach with none (qualifier: none). In ICD-10-PCS, pharmacotherapy means the use of replacement medications for the treatment of addiction.
In plain terms, this corresponds to alcohol rehabilitation and drug rehabilitation, the ICD-9-CM procedure titles it maps to (94.61 and 94.64).
For a different body part, codes include HZ90ZZZ (nicotine replacement), HZ91ZZZ (methadone maintenance), HZ92ZZZ (levo-alpha-acetyl-methadol (LAAM)), HZ93ZZZ (antabuse), HZ94ZZZ (naltrexone), HZ95ZZZ (naloxone) and 3 more.
It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.
It has been valid since ICD-10-PCS took effect on October 1, 2015.
