Modifiers with Unlisted Codes

Question:

Can I use modifiers on an unlisted code? 

Answer:

In some circumstances, a modifier may be appropriately appended to an unlisted code. 

For example,  

• CPT says, while uncommon, if multiple separately reportable unlisted codes are performed on the same patient on the same date by the same physician, multiple unlisted codes may be reported. If the two procedures are performed in the same anatomic region, then multiple units of the unlisted code may be reported with a modifier 59 

• Modifier 62 (two surgeons/co-surgery) may also be appended to an unlisted code such as 64999 if co-surgery is documented.  

• Modifier 58 for staged or more extensive procedures may also be appended to alert the payor to a second surgery during the global period, 

• During the global period, it may also be appropriate (and recommended) to append global period modifiers such as 78 or 79 to an unlisted code to fully describe the surgical scenario to a payor. 

Do not append modifier 50 (bilateral procedure), modifier 51 or modifier 52 or 53 to an unlisted code. Your base, or comparison code, should reflect modifier 50 and the associated increase in fee. The same is true for modifier 22.

ARNP Billing Inquiry

Question:

We have an ARNP joining our practice, can you please confirm which pain management procedures they are allowed to perform.  Are they allowed to perform all procedures except RFA procedures?

Answer:

The answer to your question will depend on the NP scope of practice for your state so you will need to research this information for your state.  In addition, check provider qualification requirements with your commercial payors and your MAC. The LCDs for Facet Joint Injections Epidural Steroid Injections, and Nerve Blocks for Chronic Pain and Neuropathy list the provider qualifications.

Denials for Initial Hospital Care and Observation E/M Codes: 2024

Question:

We are experiencing denials when we bill 99221-99223 and the place of service is observation (outpatient hospital).  Are we doing something wrong?

Answer:

You are billing correctly based on CPT 2023 guidelines for E/M that merged inpatient hospital encounters/codes with observation encounters/codes.  Unfortunately, some payor claims processing systems may not yet recognize these changes as they apply to billing.  You will have to appeal these denied claims, with CPT references showing the current guidelines for E/M reporting.
