How Codes Work Together
To report the patient's condition, the services rendered and supplies for claims processing, codes from all three coding systems must be used: CPT, HCPCS and ICD-10-CM.
For example, to code for chemodenervation of the bladder with injection of Botox®a collagen skin test and implant for overactive bladder (CPT, HCPCS and ICD-10-CM) when performed in the physician's office, CPT states that the supply of the chemodenervation agent is reported separately from the procedure.
On the day of the procedure, the physician's service along with the cost of the implant would be billed:
|Cystourethroscopy, with injection(s) for chemodenervation of the bladder|
|HCPCS J0585||Injection, onabotulinumtoxinaA, 1 unit. (This code would be billed based on the number of units injected into the bladder.)|
In addition, ICD-10 diagnostic codes are available to support medical necessity for the performance of this procedure:
|G83.4||Cauda equina syndrome|
|N31.0||Uninhibited neuropathic bladder, not elsewhere classified|
|N31.8||Other neuromuscular dysfunction of bladder|
|N31.9||Neuromuscular dysfunction of bladder, unspecified|
|N39.498||Other specified urinary incontinence|
|R35.0||Frequency of micturition|
|R39.15||Urgency of urination|
