Modifiers TA and T1-T9
When billing toe or toenail surgeries, Modifiers TA and T1-T9 are necessary to ensure services are processed and paid correctly.
HCPCS Level II toe Modifiers TA and T1-T9 are anatomical modifiers that describe procedures performed on the right and left foot digits. It is incorrect to additionally append Modifiers LT and/or RT. It is also incorrect to use modifier 59 and/or modifier 59 subset “X modifiers” (XE, XS, XP, XU).
Failure to use these modifiers appropriately may result in claims denial. Additionally, post audits will be performed and will result in recoupments if documentation reviewed supports unbundling by incorrect use of modifiers 59, XE, XS, XP, XU, LT and RT.
Required for Claims : Hospital Outpatient Prospective Payment System
Type of Bill : 13X
Coding Guidelines : Generally applied to surgical (CPT 10000-69990) and other diagnostic services
General Guidelines :
* Apply the appropriate modifiers for procedures involving eyelids, fingers and toes. Use the most specific modifier available.
* If more than one level II modifier applies, repeat each line item with the appropriate level II modifiers
* Do not use if CPT/HCPCS code indicates multiple occurrences.
* Do not use if the code indicates the procedure applies to different body parts.
Example: Patient comes to the hospital for drainage of an abscess on the fifth digit on the right hand.
26010 Drainage of finger abscess; simple (Use appropriate modifier to identify the fifth digit on the right hand)
Billing Guide to Avoid Medically unlikely Edit
some instances, it may be appropriate for a provider to report medically reasonable and necessary units of service in excess of a MUE value. Since each line of a claim is adjudicated separately against the MUE value for the code on that line, appropriate CPT modifiers should be used to report medically reasonable and necessary units of service in excess of an MUE value. CPT modifiers such as -76 (repeat procedure by same physician), -77 (repeat procedure by another physician), anatomic modifiers (e.g. RT, LT, F1, F2), -91 (repeat clinical diagnostic laboratory test), and -59 (distinct procedural service) will accomplish this purpose. Modifier -59 should be utilized only if no other modifier describes the service
The current NCCI-associated modifiers are: E1, E2, E3, E4, FA, F1, F2, F3, F4, F5, F6, F7, F8, F9, LC, LD, RC, LT, RT, TA, T1, T2, T3, T4, T5, T6, T7, T8, T9, 25, 27, 58, 59, 78, 79, and 91. Additional modifiers shall be added to the above list of NCCI-associated modifiers that will allow an edit with modifier indicator of “1” to be bypassed when the modifier is utilized correctly. These modifiers are LM (left main coronary artery), RI (ramus intermedius coronary artery), 24 (unrelated evaluation and management service by the same physician during a postoperative period), and 57 (decision for surgery).
* Procedure codes that do not specify right or left require an anatomical modifier. If an anatomical modifier is necessary to differentiate right or left and is not appended, the claim will be denied.
* Likewise, if a modifier is appended to a procedure code that does not match the appropriate anatomical site, the claim will be denied.
* Please append the modifier in 24D of the CMS 1500 claim form, or electronically report the first modifier in SV101-3; use the additional fields SV101-4, SV101-5 or SV101-6 if needed for additional modifiers relevant to the procedure code on the service line.
Would the Maximum Frequency Day value for hand or foot bilateral procedures remain at "1" unit if it is possible to perform the procedure on multiple digits such as fingers or toes?
The MFD value would remain at 1 unit, however, HCPCS modifiers FA or F1-9 may be used to report specific fingers; TA or T1-9 may be used to report specific toes.
