About 0L8N4ZZ

0L8N4ZZ is the ICD-10-PCS code for a division procedure on the right lower leg tendon using a percutaneous endoscopic approach. In ICD-10-PCS, division means cutting into a body part, without draining fluids and/or gases from the body part, in order to separate or transect a body part.

In plain terms, this corresponds to Achillotenotomy and other change in muscle or tendon length, the ICD-9-CM procedure titles it maps to (83.11 and 83.85).

For a different body part, codes include 0L804ZZ (head and neck tendon), 0L814ZZ (right shoulder tendon), 0L824ZZ (left shoulder tendon), 0L834ZZ (right upper arm tendon), 0L844ZZ (left upper arm tendon), 0L854ZZ (right lower arm and wrist tendon) and 21 more.

The same procedure with a different approach is coded 0L8N0ZZ (open) and 0L8N3ZZ (percutaneous).

It is an operating-room procedure in the MS-DRG logic for DRG 503 (Foot Procedures with MCC), DRG 504 (Foot Procedures with CC), DRG 505 (Foot Procedures without CC/MCC), DRG 907 (Other O.R. Procedures for Injuries with MCC), DRG 908 (Other O.R. Procedures for Injuries with CC) and DRG 909 (Other O.R. Procedures for Injuries without CC/MCC), under the surgical categories “Foot 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.
