About 0KMM0ZZ

0KMM0ZZ is the ICD-10-PCS code for a reattachment procedure on the perineum muscle 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 reattachment of muscle, the ICD-9-CM procedure title it maps to (83.74).

The same procedure with a different approach is coded 0KMM4ZZ (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 500 (Soft Tissue Procedures with MCC), DRG 501 (Soft Tissue Procedures with CC) and DRG 502 (Soft Tissue Procedures without CC/MCC), under the surgical categories “Peripheral, Cranial Nerve and Other Nervous System Procedures”, “Soft Tissue Procedures”, “Other O.R.
