About 0CM70ZZ

0CM70ZZ is the ICD-10-PCS code for a reattachment procedure on the tongue using an open approach. In ICD-10-PCS, reattachment means putting back in or on all or a portion of a separated body part to its normal location or other suitable location.

In plain terms, this corresponds to other repair and plastic operations on tongue, the ICD-9-CM procedure title it maps to (25.59).

For a different body part, codes include 0CM00ZZ (upper lip), 0CM10ZZ (lower lip), 0CM30ZZ (soft palate) and 0CMN0ZZ (uvula).

It is an operating-room procedure in the MS-DRG logic for DRG 137 (Mouth Procedures with CC/MCC), DRG 138 (Mouth Procedures without CC/MCC), DRG 907 (Other O.R. Procedures for Injuries with MCC), DRG 908 (Other O.R. Procedures for Injuries with CC), DRG 909 (Other O.R. Procedures for Injuries without CC/MCC) and DRG 957 (Other O.R. Procedures for Multiple Significant Trauma with MCC), under the surgical categories “Mouth Procedures”, “Other O.R. Procedures for Injuries” and “Other O.R. Procedures for Multiple Significant Trauma”.

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