About HZ81ZZZ
HZ81ZZZ is the ICD-10-PCS code for a medication management procedure on the methadone maintenance using a none approach with none (qualifier: none). In ICD-10-PCS, medication management means monitoring and adjusting the use of replacement medications for the treatment of addiction.
In plain terms, this corresponds to drug rehabilitation, the ICD-9-CM procedure title it maps to (94.64).
For a different body part, codes include HZ80ZZZ (nicotine replacement), HZ82ZZZ (levo-alpha-acetyl-methadol (LAAM)), HZ83ZZZ (antabuse), HZ84ZZZ (naltrexone), HZ85ZZZ (naloxone), HZ86ZZZ (clonidine) 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.
