The 7th character in S10-S19
A code in this block is not complete without its 7th character, and a missing one is a rejected claim rather than a denied one: the clearinghouse never passes it on. 1,459 of the 1,459 codes here take one.
- A
- initial encounter
- D
- subsequent encounter
- S
- sequela
Risk adjustment in S10-S19
0 codes in this block map to a CMS-HCC, which means the diagnosis carries a risk-adjustment payment when it is documented and coded. Under-coding here is money left on the table; over-coding here is what audits are for.
- HCC 401 Vertebral Fractures without Spinal Cord Injury
- HCC 182 Spinal Cord Disorders/Injuries
- HCC 180 Quadriplegia
What else to watch in S10-S19
- 128 codes are laterality-specific. They come in left and right pairs, and the pair is mutually exclusive on a single site: coding both without a bilateral code is a contradiction a scrubber should catch before the payer does.
- 1,025 codes are named in Medicare coverage policies. An LCD or NCD lists them as supporting medical necessity, or explicitly as not supporting it. Which applies depends on the MAC for your state.
