That Medicare claims are denied by Medicare Administrative Contractors (MACs) may not be news, but what about the “Top 10 Denial Codes?”
Palmetto GBA, the nation’s largest MAC, regularly publishes the top denial codes. Earlier this week, Palmetto released December’s figures. The top codes were:
Ranking | Code | Description |
1 |
N29 |
Documentation requested for this date of service was not received or was incomplete |
2 |
N237 |
Information submitted deem illegible. |
3 |
N237 |
Documentation received contains incorrect/incomplete/invalid patient identification or date of service |
4 |
50 |
Payer deems the information submitted does not support medical necessity of services billed |
5 |
MA81 |
Information submitted contains an invalid/illegible provider signature |
6 |
150 |
Payer deems the information submitted does not support the level of service billed; downcoded |
7 |
50 |
Per applicable LCD, payer deems the information submitted does not support medical necessity of services billed |
8 |
N237 |

8 |
N455 |
Documentation lacks the necessary provider order |
10 |
Claim billed in error per Provider |
Denial code “50″ is one of those that gives provider’s fits (rating fourth and seventh on the list), so Palmetto publishes the top reason a claim received that particular code (“This claim was fully or partially denied because there were incomplete or no documentation received for a specific DOS”).
Palmetto’s Top 10 list also breaks denials by provider type and offers recommendations on how to avoid getting claims denied. It also has made available it’s Top 10 lists for the past two years available as a zip file for download here: J1PartBMedicalReviewTopDenialReasonCodes2011-2012.zip (ZIP, 489 KB)
