Billing tips

Document the specific spinal level(s) involved (lumbar, sacral, or lumbosacral) and whether abscess is epidural, subdural, or paraspinal to support medical necessity
Impact: Prevents denials for inadequate documentation; missing anatomic specificity accounts for approximately 30% of audit-related payment takebacks
Bill only once per operative session regardless of number of levels drained; 22015 is not a per-level code
Impact: Prevents automatic denials and potential fraud allegations; unbundling could trigger $940.64+ overpayment recovery plus penalties
Attach modifier 22 with detailed operative note when procedure time exceeds 90 minutes or involves extensive adhesiolysis, multiple loculations, or revision scenario
Impact: Can increase reimbursement by $188-$470 (20-50% above base rate) when supported by clear documentation of increased complexity
Use appropriate ICD-10 codes specifying infection type and location (e.g., M46.26-M46.28 for osteomyelitis, G06.1 for intraspinal abscess) to establish medical necessity
Impact: Matching diagnosis codes prevent medical necessity denials which account for 25% of claim rejections for this procedure
Separate billing for percutaneous drainage (10030) if performed on different date; do not bill both on same operative date
Impact: Prevents bundling denials and potential $940.64 recoupment; CCI edits bundle percutaneous and open approaches on same date
For post-operative infections following instrumented fusion, document whether drainage is related to original surgery (modifier 78) or new unrelated infection (modifier 79)

No, CPT 22015 is billed once per operative session regardless of the number of lumbar, sacral, or lumbosacral levels involved in the abscess drainage. It is not a per-level code. Billing multiple units will result in denial.

What is the difference between CPT 22015 and 22010?

CPT 22015 is specific to incision and drainage of abscesses in the posterior lumbar, sacral, or lumbosacral spine, while CPT 22010 covers the same procedure in the cervical, thoracic, or cervicothoracic spine. The anatomic location determines the correct code.

How do I bill CPT 22015 when performed during the global period of a previous spinal surgery?

Use modifier 78 if the abscess drainage is related to the original surgery (e.g., post-operative infection) or modifier 79 if it is completely unrelated. Modifier 78 results in reduced reimbursement, while modifier 79 allows full payment of $940.64 when properly documented.

Is CPT 22015 bundled with spinal fusion or decompression procedures?
