About 00SS0ZZ

00SS0ZZ is the ICD-10-PCS code for a reposition procedure on the hypoglossal nerve using an open approach. In ICD-10-PCS, reposition means moving to its normal location, or other suitable location, all or a portion of a body part.

In plain terms, this corresponds to transposition of cranial and peripheral nerves, the ICD-9-CM procedure title it maps to (04.6).

For a different body part, codes include 00SF0ZZ (olfactory nerve), 00SG0ZZ (optic nerve), 00SH0ZZ (oculomotor nerve), 00SJ0ZZ (trochlear nerve), 00SK0ZZ (trigeminal nerve), 00SL0ZZ (abducens nerve) and 8 more.

The same procedure with a different approach is coded 00SS3ZZ (percutaneous) and 00SS4ZZ (percutaneous endoscopic).

It is an operating-room procedure in the MS-DRG logic for DRG 040 (Peripheral, Cranial Nerve and Other Nervous System Procedures with MCC), DRG 041 (Peripheral, Cranial Nerve and Other Nervous System Procedures with CC or Peripheral Neurostimulator), DRG 042 (Peripheral, Cranial Nerve and Other Nervous System Procedures without CC/MCC), DRG 957 (Other O.R. Procedures for Multiple Significant Trauma with MCC), DRG 958 (Other O.R. Procedures for Multiple Significant Trauma with CC) and DRG 959 (Other O.R. Procedures for Multiple Significant Trauma without CC/MCC), under the surgical categories “Peripheral, Cranial Nerve and Other Nervous System Procedures” and “Other O.R. Procedures for Multiple Significant Trauma”.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
