About coding Co-sleeping
The ICD-10-CM code for Co-sleeping is Z72.823 (Risk of suffocation (smothering) under another while sleeping).
Within Z72.82 (problems related to sleep), Z72.823 is specifically for risk of suffocation (smothering) under another while sleeping. Related codes cover sleep deprivation (Z72.820) and inadequate sleep hygiene (Z72.821).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
In MS-DRG v44.0, it is part of the grouping logic for DRG 951 (Other Factors Influencing Health Status, relative weight 0.5577), in MDC 23 (Factors Influencing Health Status and Other Contacts with Health Services), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
